knife safety : apply tension only away from you, when walking/running/climbing stairs hold it with the blade downwards like the murderer in psycho angle grinder safety : 30 minute long video therefore I propose the formula d = u^4 where u = usefulness and d = danger
A model video for others to aspire to. No inane "what's up guys" intro; no boring, self-indulgent efforts at humour, and no irrelevant chatter about the personal life of the presenter. Just a very well presented, very informative and interesting video, containing everything anyone contemplating use of a grinder should know about using one safely.
This is me: 1. Arrogantly thinks I don't need to see the safety tips part " it's boring." 2. Googles grinder accident images. 3. Humbly goes to Home Depot and buys all the recommended safety supplies 4. Finishes watching video and makes wife breath a sigh of relief. 5 Subscribes to Channel. 6 Thanks the Ultimate Handyman for possibly preventing a horrific accident.
Really love the emphasis on PPE, safety is number 1. Don't ever let people make you feel bad about using protection, there are too many examples of accidents to mention. Great video!
Apologies for not uploading a video last week but I am incredibly busy. This video took me days to film (in a cold garage) and edit. I’m sorry that the video is so long but it was difficult trying to cram most of what you learn on an 8 hour abrasive wheel training course into a 30 minute video. If you could please like, comment and share the video that would be much appreciated! I hope everyone has a great Sunday ;-)
Wow what a fantastic video, when it comes to safety there are no compromises. I watched this through as while I’ve bought my Dewalt battery powered unit I’m still to try it out. So for me this was just the job. Thank you for delivering this video, only one way to tell it and you did. Regards Mike
Hey Chez, Happy New Year Mate !, Thanks for taking the time out of your busy days to create and post another great video, I watched every second. These days, I am but a Home DIY’er, but I do own a grinder with a selection of Metal, Masonry, and wire wheels - and the PPE to go with it ! Though I haven’t yet used it, although I have seen how versatile they are, and have watched the safety videos too ! The reason I bought it ? - The batteries ! It’s the DeWalt 60V Flexvolt version ( I’m British, but live in Texas - I think you have them over there, but it’s the 54V Line, same thing, just marketing... ) Anyway, Came across a great Sale, Where I could get TWO of the batteries, the rapid charger and the Grinder itself, for the price of One battery !, couldn’t turn it down, as I already have other Flexvolt tools, plus these batteries are backwards compatible with the 20V ( British 18V ) line, of which I have a few too... I don’t do a lot of metal work, though I may use it soon to do some paint removal ( Mask ! ), And a friend recently discovered he’s lost the key to the lock on his storage unit ... Another reason the battery version will come in handy - Nowhere to plug anything in out where that is.... Anyway Mate, I’m droning on, thanks for the info and advice, Stay safe !
Hi Tom, Happy new year ;-) The Flexvolt stuff looks amazing and from what I have seen it is just like using a mains powered machine. The new (to me) paint removal discs are superb - ua-cam.com/video/aMQMk7J94u8/v-deo.html The beauty of grinders is that they will cut through anything, so it will make real light work of a lock on a storage unit. Have fun with the grinder and stay safe mate ;-) Thanks for the comment
Just when I thought I know enough to buy my first grinder. Never really thought about the danger except flying sparks. Thank the Lord I came here. Thank you boss!
I've never felt nervous about using power tools, recently became a bit of a diy hobbyist during the pandemic; but I must say that the Angle Grinder made me nervous as soon as I tested it out and realised the rotation speed and forces involved. Great video!
Thank you for taking the time to make this. I read below it took you days. I always knew they were called an angle grinder but saw people using them for cutting and polishing in other videos etc... so it's great to finally understand about the different discs and the proper methods of use (i.e. _not_ actually using a cutting disc at an angle). Believe it or not there are people like me who've only ever used a power drill. I can't understand those that are saying you're too pedantic - It's better to show something being done correctly, safely, properly. Once someone is proficient and experienced they can make their own choices about taking shortcuts (I'd hope they don't put anyone else at risk) but it's stupid to learn badly in the first place. Those google accident images were really eye opening. Cheers much appreciated.
One of the most comprehensive, thorough, and well-presented videos I've seen. Part on damaged flange nuts from people using screwdrivers/hammers is advice that could only come from a seasoned veteran. Thank you.
So I just bought my 1st angle grinder for the specific use of removing rust; I am my personal handy-woman. I had watched another video on angle grinders by See Jane Drill who stated that this is the 2nd most dangerous tool after the table saw. That is when I decided to watch more safety videos. Your video is EXCELLENT! I now feel much more confident using the grinder and I am glad I have the appropriate PPE. Thanks so much for being so thorough. Also, I love your accent!
Agreed i have also just got my first grinder and not going to lie it scares the hell out of me but i need it for a very specific job, i have purchased the protection but i am amazed they don't sell anything to protect necks, i have read horror stories about the disc exploding and killed someone when it slashed his neck, i tucked my head and neck right into my mask!
Brilliant video, and so glad I watched all the way through. Having just purchased a DeWalt angle grinder, I am a novice so this video goes through all the types of discs and recommendations clearly. The hints and tips are extremely useful, and the health and safety aspects are handled with authority, without ramming it down your throats. You won't regret watching this. Very well done sir.
I agree, this was incredible and really stressed the safety aspects of this very dangerous machine. I just bought one for a single job in my house, and going in without knowing what you're doing can lead to very serious problems. Who would have thought the discs have an expiration date and can cause so much damage - I will just throw mine out after use so I don't forget and use in 10 years
Hope ur well uhm to be honest I would much rather be called names than be seriously injured. I’ve had a disk explode on me but as I had my face guard on and welding coat so I was absolutely fine. Very informative video !!
Thank you so much for the great comprehensive video, just purchased my first angle grinder and after watching the video, I now have the confidence to use it correctly and safely.
One of the best and structural and safety videos on grinders I have seen thank you so much I actually learned quite a bit from it thanks again great videos one that everyone should see especially beginners
Great great information! Thank you. Would love to see a part 2 where you cover proper grinder use. I burned out my first angle grinder on it's third use. Having a video on how to tell when you are bogging the grinder down or when it's getting caught in a sticky surface coating would really be helpful
Best spent 30 minutes before i start using my newly bought angle grinder. Thank you for all the clear information. EXCELLENT! EXECELLENT VIDEO. Thank you for all the very useful safety information and the coverage of types of discs. Best video I have ever seen.
I’m so glad I found this video. I have a small job to do. I was going to rent an angle grinder at my local home center but changed my mind after watching this. I’m still going to do my job but I’m going to use human powered tools (hack saw, files etc). Thank you for your professional and no nonsense instruction and advice.
An excellent and very informative presentation. I have been using angle grinders for decades, and didn't realize that some of the things I have been doing were both wrong and dangerous. I now know better. Thank you.
i respect you for the PPE emphasis - for the total noob like me who didnt learn about these kinda things in school or collegue - its all super useful. FK the haters bro keep doing ya things - absolutely love your vids mate
Enjoyed that learned alot about grinder which i really should already know having used them my entire working life. I had no idea they had a "use by date" and in all honesty im that guy who removes the guards and says "Can't see F all with that on there". Think i will be checking my discs from now on and perhaps reinstalling a guard or two.
I've been using a grinder for 30 years but I too never knew about the expiry date until I did an abrasive wheels course a few years back. The guard can be a pain in the backside but it is there for a very good reason. Thanks for the comment
Great video. This comment is from a person that has been a welder and metal working for over 30 years, I will always respect the angle grinder. I had a cutting disc brake and a piece from the cutting disc ripped through my leather glove and embedded itself between my knuckles.
Very very nice video. Especially the safety part. For me the worst with wire brushes for angle grinders is that they are usually unbalanced causing serious vibrations.
I hate wire brushes in grinders, I once had to use some when cleaning a weld on a large vessel and I was covered in metal bristles afterwards. Thanks for the comment
Been using an angle grinder for years, but still learnt a thing or two from this vid. 👍🏻Complacency is a very dangerous attitude, especially with any cutting, grinding or slicing equipment. Don’t ever apologise for using PPE, I’ve seen a lot of nasty injuries over the years. Stay smart. Stay safe. 5⭐️
I found it to be an excellent refresher, as I haven't used a grinder for years. Now I will buy the safety gear you recommend. I will always have a heakthy respect for the injury causing potential of grinders as well as table saws and anything with a fast rotating, reciprocating, or otherwise moving blade. The grinder adds the risk of exploding disks, flying scrapnel, and fire/burn causing sparks. It is the dragon of power tools. Thanks again.
all them one eye deaf people calling you a coward for wearing PPE....yep you can usually squeeze a 5 inch in a bosch grinder, hmm not saying anything rude!. why is it americans seem most likely to not have the blade guard?
Funnily enough I saw an American TV program yesterday where a company was making underground steel bunkers for preppers and the guys using the grinders did not have blade guards on! Thanks for the comment
In some ways you are (in my opinion) a bit too pedantic about safety and "proper uses", as i think probably no one is following all of the rules when on a real jobsite On the other hand I really admire you and I think you should always point out what is the right procedure to do something nowadays a lot of people, myself included, are approaching DIY project without any formal training, learning from videos and guides on the internet; doing this can be really useful, but I do admit that a lot of times we tend to pick up bad habits just because we see people doing that, without even knowing why in this situation videos like this are really helpful as they give us the knowledge we lack, because we haven't studied it at school or on a jobsite, so that we fully understand what we are doing, what we are risking, what we should do and what we shouldn't but, most important, why thank you
Thanks, when I first started my website (before UA-cam was heard of) I used to write articles and take pictures of how to do D.I.Y tasks. Back then I used to frequent a few webmaster forums and stumbled across a guy that had a website that was aimed at trailer repair (caravans), he looked at a few of my articles and picked on one in particular that said "simply knock in a nail", in one of the paragraphs. He told me that you can't tell people to "simply knock in a nail" as many people do not know how to do it! From that day on I always tried to make my articles (and videos) absolutely idiot proof (which can make me seem pedantic). As I have mentioned in previous comments, there are a lot of videos and you can even see this on US TV programs where people are using angle grinders without the guard. This is downright dangerous and if people think the guard is not needed they will remove it. I've been lucky to go on courses through my work and feel it is important to pass on information that I have learnt which could keep people safe. Thanks for watching the video and taking the time to comment ;-)
At first, I didn't want to watch because of the 28 minute run time, but wow, I am GLAD that I did. You provided some really REALLy helpful information, and I really appreciate that. Thank you so much!
I've cut myself with an angle grinder a few times and every time it was because of kick back. Once I was grinding the top of a tank of some sort with a flap disk... I was on my knees in a very awkward position with all kind of pipes and stuff around me and the grinder then decided to catch on something and jump straight to my knee. It made a nice oval hole. Remember the trousers being soaked with red liquid. Another incident happened while cutting some steel structure right in front of my face. The grinder then got this great idea to make a quick jump to my face. First I was like... "what just happened" Then I felt something warm and wet gushing down my mouth. the thin cutting disk had made about a 3cm long straight hole between the nose and upper lip. the grinder really just made contact for a fraction of a second in both incidents but it surely cut flesh with ease.
I do know a guy that lost his eye when using a grinder, I should have mentioned it in the video but forgot. Accidents happen very quickly with these machines, often in a fraction of a second. I'm glad you are still ok despite the accidents ;-) Thanks for the comment
I totally agree, angle grinders should only be made with anti-kickback feature, it should be a must, it is a very useful tool but at the same time very dangerous in the wrong hands....
It can be caused when the created gap in the work piece closes onto the rotating disc, say for example you were cutting a large piece of 3 inch square bar that was 6 feet in length and you tried to cut it in the middle to make 2,three foot lengths. If the metal was not supported correctly it could sag in the middle causing the disc to be pinched.
The best video on angle grinders on the internet; perfect balance between safety and practicality, ie what each kind of disk does and does not do, and how to fit them correctly. Liked and subscribed.
thorough, much needed for us backyard enthusiasts. The angle grinder can be a fearsome and dangerous tool in the wrong hands, and needs to be treated with much respect.
Thank you for an excellent teaching demonstration. I'm 71 yrs and have been a wood worker. I had never used an angle grinder until last summer when my good friend asked me to help him with a project. He pulled out an angle grinder and removed several nails and screws that had to go so we could continue. I would have pulled out a screwdriver, hammer and claw, but was amazed at how effective the grinder was. I bought one soon thereafter. Hadn't used it until yesterday and quickly realized I needed to get some basic information about everything concerning the grinder. Your video was perfectly attuned to what I needed. Again, thank you so much, I feel I'll be a lot safer now when using it.
I have used a nine-inch angle grinder to cut through a re-enforced concrete slab in a confined space [a stove alcove] and it was like being in a firefight. I truly respect your advice as I realized just how dangerous this machine was. It is a matter of concern that cheaply made power tools of this kind can be freely available to people on a tight budget who imagine that these can be used D.I.Y. without proper training.
Excellent video mate. I’m a retired Fitter & Turner and have used an angle grinder many times in my trade as well as at home on many projects. I learned quite a few useful tips from your video. You’re never too old to learn, certainly holds true in my case. 😊👍👍🇦🇺🦘
Just bought a new angle grinder. Been looking through UA-cam for instructional videos and stumbled open this one after so many. Very clear, simple instruction and I’ve learned a lot. Thank you.
no, it was not boring at all. thank you so much for all the info! your time and efforts, its MUST watch video before using angle grinder. no waste of time and all points covered very nicely.
This video is an excellent summary of years of experience, which usually taught at good amount of money. Anyone watching this video should show some respect to the effort.
I've wanted an angle grinder for some time now to use in the garage for various cutting and grinding jobs. I will be getting one some time in the next year, and maybe this Christmas if my wife sees my list of wanted tools. All that being said, I am really glad that I stumbled upon this video and really appreciate your words of wisdom. The pictures on Google are horrific, and I wonder what's now going through the minds of all those fellows who had accidents. Do they wish now that they had taken better precautions? I imagine so. This video might have just saved one of my eyes, or the teeth in my mouth, or my life. Thank you. You have every right to sleep soundly with a good conscience.
I'm glad the video helped. I am not sure what some people are thinking when they have such bad accidents with grinders, I have also seen some road collisions and wondered what the hell the driver was doing to cause such an accident! The correct PPE will certainly help to keep you safe with the grinder. Thanks for the comment 👍
I am 55 years old and, to my discredit, wish I had paid more attention interest to my woodwork / metalwork teachers at school. I am a late starter but have just bought an old cottage - doesn't need major renos but I find myself needing to some basic handyman stuff. Before I go and get my angle grinder, I am doing my homework and came across your video. Wow. THANK YOU. Amazing amount of content. I watched it TWICE and have made copious notes. I was feeling scared about using one of these things but I feel more at ease now about my first foray into doing stuff i should have been doing years ago. I really liked your emphasis on safety - all points duly noted. I even asked one of my friends who is a DIY snob and HE CUTS COPPER with his angle grinder!!! I did enjoy telling him why he shouldn't. It was exquisite. Thanks VERY much for sharing your experience and passion. You have a real teaching gift - consider me inspired.
Excellent "how to" video on using Angle Grinder and its danger if not used correctly. Very helpful safety tips. Watch it before using an Angle Grinder. Thanks a lot.
Omg! I've been using an angle grinder professionally for 39 years and your video has taught me so much. You have saved my life literally. I have a cable tie to lock the switch on the 9 inch and i just plug it in when my apprentice is ready. He just kicks out the plug when he's done. None of our grinders have guards so the discs become one size fits all. Makes it a bit cheaper. We also made a chainsaw attachment for the 5 inch. We used the guard for that.
Thank you for your instruction. Forget the naysayers. New to metal work here, using it to take out rivets and unmount school bus seats, repair & modify bbq pits. Also, to cut 55 gallon barrels. I do make sure the insides are not flammable from previous usage. Very informative, and will take your safety guidance seriously. Im using a 11amp 4 1/2 inch Milwaukee grinder. A suggestion: please provide a usage chart; different discs and size thicknesses to apply to various metals, wood, tile and brick application, and why? Great concise common sense approach overall and well done video to compress much info!
i feel much more confident getting to know my new and first angle grinder after this video. I appreciate all of the PPE advice. much respect and gratitude
Excellent explanations especially about the dangers of using one incorrectly. I have seen a disc shatter and hit a worker and almost cut his leg in two. Poor fellow spent a long time in hospital and was lucky it missed his groin. Was not aware of the expiry date but glad I watched your video. Cheers.
This was very helpful, thanks. I’m a home handyman, have used all sorts of power tools correctly and incorrectly at different times, but I have a big grinding job coming up and this was just what I needed! (Best when played at 2x speed tho 😁)
Been using a masonry grinder with water to try to keep the dust down, didn't know that it would degrade the disk and risk exploding it. Very glad I watched this before anything bad happened. Going to take a safety course and make sure I know everything I need to know before picking up another angle grinder. Very timely video, and very informative, thank you!
I've seen people cutting metal on UA-cam, using water to prevent the metal getting hot and it always makes me cringe. If you use a diamond disc you can use water as it will not effect the disc. It's worth going on an abrasive wheels course though as they should cover everything. Thanks for the comment
Thanks. I was completely in aware of how dangerous they were. I googled some injury images & I will remember them before I am behind the machine to keep my safety up
I'm not sure, to be honest. I have seen videos of some of them in use ( I think one brand is Lenox), but they just don't seem as effective at cutting as an abrasive disc. I'm sure they are safe, but I'm just not sure how effective they are. I might have to buy one to test it out, at some point ;-) Thanks for the comments 👍
Thank you for taking the time to make a detailed safety video that explains the proper uses and ways to use these tools. I can tell you right now, I was definitely asking for trouble sooner or later with the way I was using then prior to this video.
PPE saves lives. I’m horrified how many builders/trades work with no regard for their safety or the safety of others. Thanks so much for this detailed video. I bought an angle grinder a year or so ago and I’ve always been terrified of it! This has covered all the questions I had and more! Thanks
I'd just like to thank you so much for this video. I just purchased an angle grinder...and I had no idea they were dangerous. Doing that google search was eye-opening!
Great video. My father cut his forearm open with an angle grinder when I was young. Something like 30 internal stitches and about the same external. He was lucky. He was never silly with tools but he got complacent. He was a lot more cautious with the grinder after. I have a quick job to do with a grinder this week, given my father’s history I wanted to be safe. This has been exactly what I needed.
This video is superbly comprehensive for both training and safety. Essential viewing for an occasional user of grinders like myself and yes, I did learn a few things. Great stuff.
Great video.I went from being scared witless of angle grinders and NEVER using one,to it being my most used tool for all sorts of applications.I now have two Dewalt cordless grinders,inc the Flexvolt,and a 9" Metabo corded. It is by far the most useful tool ive got. Thankyou for making me a grinder addict lol !
I work in Occupational Health and Safety. People underestimate the danger of angle grinders, there are horrible incidents that happen daily around the world. Your suggestion of having people Google the results of the incidents is a great way to open their eyes to the risks...
Thank you for this very informative video. I purchased a angle grinder to sharpen my lawnmower blades and garden tools. Now I know is has many more uses.
Not boring at all. Now I’ve been fully informed and will go and buy an angle grinder. You’ve told me everything I wanted to know especially about the safety tips.👍🏽thanks bro ✊🏽
Wow, this is a very comprehensive safety video! The best I have seen to date. I decided to check this out after I saw the damage one of those chainsaw disks can do! Best 30 minutes I've spent on you tube in a loooong time!
Best spent 30 minutes before i start using my newly bought angle grinder. Thank you for all the clear information.
Thanks for the comment
Great video as usual. I didn't even know about the expiry date on disc so lesson learnt thanks.
I would also like to add this is also a very good video, well worth a watch before touching the tool.
Very informative video. Thank you.
knife safety : apply tension only away from you, when walking/running/climbing stairs hold it with the blade downwards like the murderer in psycho
angle grinder safety : 30 minute long video
therefore I propose the formula d = u^4 where u = usefulness and d = danger
A model video for others to aspire to. No inane "what's up guys" intro; no boring, self-indulgent efforts at humour, and no irrelevant chatter about the personal life of the presenter. Just a very well presented, very informative and interesting video, containing everything anyone contemplating use of a grinder should know about using one safely.
Wow, thank you!
Well said.

Hi Tom, Happy new year ;-)
The Flexvolt stuff looks amazing and from what I have seen it is just like using a mains powered machine.
The new (to me) paint removal discs are superb - ua-cam.com/video/aMQMk7J94u8/v-deo.html
The beauty of grinders is that they will cut through anything, so it will make real light work of a lock on a storage unit.
Have fun with the grinder and stay safe mate ;-)
Thanks for the comment

Great video! Very informative! Thank you!!!!
1. box knife
2. angle grinder
3. chainsaw
Those are in order by how many accidents ive had.
Agreed i have also just got my first grinder and not going to lie it scares the hell out of me but i need it for a very specific job, i have purchased the protection but i am amazed they don't sell anything to protect necks, i have read horror stories about the disc exploding and killed someone when it slashed his neck, i tucked my head and neck right into my mask!

I'm good thanks, but very busy (as usual). I'm glad you had your PPE on when the disk exploded ;-)
Thanks for the comment
People who call you such names for being safe are Darwin Award contestants. Think of the mindset, yikes!
My safety is never too boring. Thanks for getting me started with my new tool.
Best of luck with it 👍
Absolutely brilliant !
Most comprehensive - I learnt a lot and will watch this video a few more times.
Many thanks.
I'm glad you like the video ;-)
Thanks for the comment
I don't think I can overstate how important videos like this are. Thank you
You are welcome
Thanks for the comment ;-)
Yeah. Right. Congratulations on your up coming workplace safety inspector job.
Thank you so much for the great comprehensive video, just purchased my first angle grinder and after watching the video, I now have the confidence to use it correctly and safely.

I’m so glad I found this video. I have a small job to do. I was going to rent an angle grinder at my local home center but changed my mind after watching this. I’m still going to do my job but I’m going to use human powered tools (hack saw, files etc). Thank you for your professional and no nonsense instruction and advice.
Best of luck with it 👍
perfectly informative! Thank you for the safety information which I didn't find to be overkill at all. I want to keep my body parts in tact!
You are welcome
Thanks for the comment
An excellent and very informative presentation.
I have been using angle grinders for decades, and didn't realize that some of the things I have been doing were both wrong and dangerous.
I now know better.
Thank you.
Glad it was helpful!
Thanks for the comment 👍
i respect you for the PPE emphasis - for the total noob like me who didnt learn about these kinda things in school or collegue - its all super useful. FK the haters bro keep doing ya things - absolutely love your vids mate
Thanks Adam ;-)
Best angle grinder training video, getting my first grinder soon. Re watch this again a few times. Thanks
Best video I have watch. Thanks for taking the time to make this outstanding informative video. Cool....
Thanks for the comment
Well done. I'm always careful with tools but figured I'd listen to an actual video. Learned so much. Thank for sharing the knowledge.
I’m glad you found the video useful
Thanks for the comment 👍
Enjoyed that learned alot about grinder which i really should already know having used them my entire working life. I had no idea they had a "use by date" and in all honesty im that guy who removes the guards and says "Can't see F all with that on there". Think i will be checking my discs from now on and perhaps reinstalling a guard or two.
I've been using a grinder for 30 years but I too never knew about the expiry date until I did an abrasive wheels course a few years back. The guard can be a pain in the backside but it is there for a very good reason.
Thanks for the comment
A guard or two? I don't think it's really possible to install more than one at a time on the machine.
Great video. This comment is from a person that has been a welder and metal working for over 30 years, I will always respect the angle grinder. I had a cutting disc brake and a piece from the cutting disc ripped through my leather glove and embedded itself between my knuckles.
Well said!
Thanks for the comment 👍
Very very nice video. Especially the safety part.
For me the worst with wire brushes for angle grinders is that they are usually unbalanced causing serious vibrations.
I hate wire brushes in grinders, I once had to use some when cleaning a weld on a large vessel and I was covered in metal bristles afterwards.
Thanks for the comment
Been using an angle grinder for years, but still learnt a thing or two from this vid. 👍🏻Complacency is a very dangerous attitude, especially with any cutting, grinding or slicing equipment. Don’t ever apologise for using PPE, I’ve seen a lot of nasty injuries over the years. Stay smart. Stay safe. 5⭐️
👍
I’ve learnt a lot yet again. Thank you.
You are welcome
Thanks for the comment
- This video, unquestionably, is the most in depth, relevant, useful info on Angle Grinders on the internet. Thanx 4 sharing.
Wow, thanks!
Thanks, solid in depth info. I really appreciate the tips
You are welcome
Thanks for the comment
I found it to be an excellent refresher, as I haven't used a grinder for years. Now I will buy the safety gear you recommend. I will always have a heakthy respect for the injury causing potential of grinders as well as table saws and anything with a fast rotating, reciprocating, or otherwise moving blade. The grinder adds the risk of exploding disks, flying scrapnel, and fire/burn causing sparks. It is the dragon of power tools. Thanks again.
I’m glad you found the video useful
Thanks for the comment 👍
Thank you for this great video 👍
You are welcome
Thanks for the comment
Excellent safety information for a tool novice like me, thank you.
all them one eye deaf people calling you a coward for wearing PPE....yep you can usually squeeze a 5 inch in a bosch grinder, hmm not saying anything rude!. why is it americans seem most likely to not have the blade guard?
Funnily enough I saw an American TV program yesterday where a company was making underground steel bunkers for preppers and the guys using the grinders did not have blade guards on!
Thanks for the comment
Thank you for for taking the time to show me the ropes.
You are welcome
Thanks for the comment 👍
In some ways you are (in my opinion) a bit too pedantic about safety and "proper uses", as i think probably no one is following all of the rules when on a real jobsite
On the other hand I really admire you and I think you should always point out what is the right procedure to do something
nowadays a lot of people, myself included, are approaching DIY project without any formal training, learning from videos and guides on the internet; doing this can be really useful, but I do admit that a lot of times we tend to pick up bad habits just because we see people doing that, without even knowing why
in this situation videos like this are really helpful as they give us the knowledge we lack, because we haven't studied it at school or on a jobsite, so that we fully understand what we are doing, what we are risking, what we should do and what we shouldn't but, most important, why
thank you
Thanks, when I first started my website (before UA-cam was heard of) I used to write articles and take pictures of how to do D.I.Y tasks. Back then I used to frequent a few webmaster forums and stumbled across a guy that had a website that was aimed at trailer repair (caravans), he looked at a few of my articles and picked on one in particular that said "simply knock in a nail", in one of the paragraphs. He told me that you can't tell people to "simply knock in a nail" as many people do not know how to do it!
From that day on I always tried to make my articles (and videos) absolutely idiot proof (which can make me seem pedantic).
As I have mentioned in previous comments, there are a lot of videos and you can even see this on US TV programs where people are using angle grinders without the guard. This is downright dangerous and if people think the guard is not needed they will remove it.
I've been lucky to go on courses through my work and feel it is important to pass on information that I have learnt which could keep people safe.
Thanks for watching the video and taking the time to comment ;-)
At first, I didn't want to watch because of the 28 minute run time, but wow, I am GLAD that I did. You provided some really REALLy helpful information, and I really appreciate that. Thank you so much!
Glad it was helpful! 👍
I've cut myself with an angle grinder a few times and every time it was because of kick back. Once I was grinding the top of a tank of some sort with a flap disk... I was on my knees in a very awkward position with all kind of pipes and stuff around me and the grinder then decided to catch on something and jump straight to my knee. It made a nice oval hole. Remember the trousers being soaked with red liquid.
Another incident happened while cutting some steel structure right in front of my face. The grinder then got this great idea to make a quick jump to my face.
First I was like... "what just happened"
Then I felt something warm and wet gushing down my mouth.
the thin cutting disk had made about a 3cm long straight hole between the nose and upper lip.
the grinder really just made contact for a fraction of a second in both incidents but it surely cut flesh with ease.
I do know a guy that lost his eye when using a grinder, I should have mentioned it in the video but forgot.
Accidents happen very quickly with these machines, often in a fraction of a second.
I'm glad you are still ok despite the accidents ;-)
Thanks for the comment
Some newer grinders come with anti-kickback features.
I totally agree, angle grinders should only be made with anti-kickback feature, it should be a must, it is a very useful tool but at the same time very dangerous in the wrong hands....
So what causes kick-back? Excellent video BTW.
It can be caused when the created gap in the work piece closes onto the rotating disc, say for example you were cutting a large piece of 3 inch square bar that was 6 feet in length and you tried to cut it in the middle to make 2,three foot lengths. If the metal was not supported correctly it could sag in the middle causing the disc to be pinched.
The best video on angle grinders on the internet; perfect balance between safety and practicality, ie what each kind of disk does and does not do, and how to fit them correctly. Liked and subscribed.
Wow, thanks! 👍
thorough, much needed for us backyard enthusiasts. The angle grinder can be a fearsome and dangerous tool in the wrong hands, and needs to be treated with much respect.
👍
Thank you for an excellent teaching demonstration. I'm 71 yrs and have been a wood worker. I had never used an angle grinder until last summer when my good friend asked me to help him with a project. He pulled out an angle grinder and removed several nails and screws that had to go so we could continue. I would have pulled out a screwdriver, hammer and claw, but was amazed at how effective the grinder was. I bought one soon thereafter. Hadn't used it until yesterday and quickly realized I needed to get some basic information about everything concerning the grinder. Your video was perfectly attuned to what I needed. Again, thank you so much, I feel I'll be a lot safer now when using it.
I'm glad the video has helped ;-)
Thanks for the comment 👍
I have used a nine-inch angle grinder to cut through a re-enforced concrete slab in a confined space [a stove alcove] and it was like being in a firefight. I truly respect your advice as I realized just how dangerous this machine was. It is a matter of concern that cheaply made power tools of this kind can be freely available to people on a tight budget who imagine that these can be used D.I.Y. without proper training.
Thanks for the comment 👍
Brilliant video, I bought an angle grinder last week and this has been very helpful in keeping me safe, thanks for taking the time to do this
Great to hear!
Thanks for the comment 👍
Excellent video mate. I’m a retired Fitter & Turner and have used an angle grinder many times in my trade as well as at home on many projects. I learned quite a few useful tips from your video. You’re never too old to learn, certainly holds true in my case. 😊👍👍🇦🇺🦘
Thanks for the comment, Brian 👍
I'm glad you picked up a couple of tips. I'm also a fitter ;-)
Just bought a new angle grinder. Been looking through UA-cam for instructional videos and stumbled open this one after so many. Very clear, simple instruction and I’ve learned a lot. Thank you.
Great to hear! 👍
no, it was not boring at all. thank you so much for all the info! your time and efforts, its MUST watch video before using angle grinder. no waste of time and all points covered very nicely.
Glad it was helpful!
Thanks for the comment 👍
This video is an excellent summary of years of experience, which usually taught at good amount of money. Anyone watching this video should show some respect to the effort.
Thanks for the comment ;-)
I've wanted an angle grinder for some time now to use in the garage for various cutting and grinding jobs. I will be getting one some time in the next year, and maybe this Christmas if my wife sees my list of wanted tools. All that being said, I am really glad that I stumbled upon this video and really appreciate your words of wisdom. The pictures on Google are horrific, and I wonder what's now going through the minds of all those fellows who had accidents. Do they wish now that they had taken better precautions? I imagine so. This video might have just saved one of my eyes, or the teeth in my mouth, or my life. Thank you. You have every right to sleep soundly with a good conscience.
I'm glad the video helped.
I am not sure what some people are thinking when they have such bad accidents with grinders, I have also seen some road collisions and wondered what the hell the driver was doing to cause such an accident!
The correct PPE will certainly help to keep you safe with the grinder.
Thanks for the comment 👍
I am 55 years old and, to my discredit, wish I had paid more attention interest to my woodwork / metalwork teachers at school. I am a late starter but have just bought an old cottage - doesn't need major renos but I find myself needing to some basic handyman stuff.
Before I go and get my angle grinder, I am doing my homework and came across your video.
Wow. THANK YOU. Amazing amount of content. I watched it TWICE and have made copious notes.
I was feeling scared about using one of these things but I feel more at ease now about my first foray into doing stuff i should have been doing years ago.
I really liked your emphasis on safety - all points duly noted.
I even asked one of my friends who is a DIY snob and HE CUTS COPPER with his angle grinder!!! I did enjoy telling him why he shouldn't. It was exquisite.
Thanks VERY much for sharing your experience and passion. You have a real teaching gift - consider me inspired.
I'm glad the video helped
Thanks for the comment 👍
:) Two years later and I came back to rewatch as a refresher course. I was as 'spell bound' today as I was the first time. Awesome info.
Excellent "how to" video on using Angle Grinder and its danger if not used correctly. Very helpful safety tips. Watch it before using an Angle Grinder. Thanks a lot.
You are welcome
Thanks for the comment 👍
Omg! I've been using an angle grinder professionally for 39 years and your video has taught me so much. You have saved my life literally. I have a cable tie to lock the switch on the 9 inch and i just plug it in when my apprentice is ready. He just kicks out the plug when he's done. None of our grinders have guards so the discs become one size fits all. Makes it a bit cheaper. We also made a chainsaw attachment for the 5 inch. We used the guard for that.
I'm glad the video helped
Thanks for the comment 👍
The clearest explanations about grinder and disc on the net so far.
I'm glad the video helped
Thanks for the comment 👍
Very useful indeed. I've not used a grinder for some time and needed a refresher. This was perfect. Thank you!
You are welcome
Thanks for the comment 👍
Thank you for your knowledge sir !. And taking safety seriously is smart. I learned a lot !.
Very comprehensive, covers every aspect and worth watching. Highly recommended for anyone new to using grinders.
Thanks for the comment 👍
Not boring at all. Very informative and helpful. You are extremely patient and safety conscious. My kind of teacher. Thank you!!
Thanks for the comment 👍
One of your best videos, its rare to learn so many important tips from one video.
Thanks for the comment 👍
Just bought an angle grinder and watched this first - really useful and glad I did, you'd be a fool if you do use one before watching this. Thanks.
I'm glad the video helped
Thanks for the comment 👍
Great video! Safety first always. I looked up the angle grinder accidents. 😱
Thanks for the comment 👍
Thank you for your instruction. Forget the naysayers. New to metal work here, using it to take out rivets and unmount school bus seats, repair & modify bbq pits. Also, to cut 55 gallon barrels. I do make sure the insides are not flammable from previous usage. Very informative, and will take your safety guidance seriously. Im using a 11amp 4 1/2 inch Milwaukee grinder. A suggestion: please provide a usage chart; different discs and size thicknesses to apply to various metals, wood, tile and brick application, and why? Great concise common sense approach overall and well done video to compress much info!
The best tool use video I've seen. An angle grinder is dangerous. You cannot be too careful. Thank you.
You are welcome
Thanks for the comment
i feel much more confident getting to know my new and first angle grinder after this video. I appreciate all of the PPE advice. much respect and gratitude
Thanks for the comment 👍
This is my go-to recommendation video for anyone who asks me about grinder safety overview. Thank you for your efforts.
You are welcome
Thanks for the comment 👍
Excellent explanations especially about the dangers of using one incorrectly. I have seen a disc shatter and hit a worker and almost cut his leg in two. Poor fellow spent a long time in hospital and was lucky it missed his groin. Was not aware of the expiry date but glad I watched your video. Cheers.
Thanks for the comment 👍
All good information, I will be having a clearout in the workshop today as I didn't realise discs had expiry dates.
I'm glad the video helped
Thanks for the comment 👍
This was very helpful, thanks. I’m a home handyman, have used all sorts of power tools correctly and incorrectly at different times, but I have a big grinding job coming up and this was just what I needed!
(Best when played at 2x speed tho 😁)
You are welcome
Thanks for the comment
Been using a masonry grinder with water to try to keep the dust down, didn't know that it would degrade the disk and risk exploding it. Very glad I watched this before anything bad happened. Going to take a safety course and make sure I know everything I need to know before picking up another angle grinder. Very timely video, and very informative, thank you!
I've seen people cutting metal on UA-cam, using water to prevent the metal getting hot and it always makes me cringe.
If you use a diamond disc you can use water as it will not effect the disc. It's worth going on an abrasive wheels course though as they should cover everything.
Thanks for the comment
Excellent video, even in 2023!
Thank you Sir
Thanks for the comment 👍
Just bought my first angle grinder,this was a great tutorial. Thanks.
Great to hear! 👍
Thanks. I was completely in aware of how dangerous they were. I googled some injury images & I will remember them before I am behind the machine to keep my safety up
Do you think metal blades for cutting aluminum or other metals are safe?
I'm not sure, to be honest. I have seen videos of some of them in use ( I think one brand is Lenox), but they just don't seem as effective at cutting as an abrasive disc. I'm sure they are safe, but I'm just not sure how effective they are.
I might have to buy one to test it out, at some point ;-)
Thanks for the comments 👍
Absolutely fantastic video. This video covered all the key point required to safely use a Grinder...thanks!
I’m glad you found the video useful
Thanks for the comment 👍
Thank you for taking the time to make a detailed safety video that explains the proper uses and ways to use these tools. I can tell you right now, I was definitely asking for trouble sooner or later with the way I was using then prior to this video.
You are welcome
Thanks for the comment 👍
PPE saves lives. I’m horrified how many builders/trades work with no regard for their safety or the safety of others. Thanks so much for this detailed video. I bought an angle grinder a year or so ago and I’ve always been terrified of it! This has covered all the questions I had and more! Thanks
You are welcome, thanks for such a positive comment ;-)
Excellent video, everyone who uses an angle grinder should watch this presentation.
I appreciate that!
I'd just like to thank you so much for this video. I just purchased an angle grinder...and I had no idea they were dangerous. Doing that google search was eye-opening!
You are welcome
Thanks for the comment
Great video. My father cut his forearm open with an angle grinder when I was young. Something like 30 internal stitches and about the same external. He was lucky. He was never silly with tools but he got complacent. He was a lot more cautious with the grinder after.
I have a quick job to do with a grinder this week, given my father’s history I wanted to be safe. This has been exactly what I needed.
I'm glad your father was patched up. I had a friend and something similar happened!
Thanks for the comment 👍
Just invested in my first cordless Dewalt angle grinder. Thank you. Great introduction and tutorial to correct handling and safe working.
I love my Dewalt cordless grinder, it is a great piece of kit ;-)
You are welcome

Great helpful safety info, Mate! I just picked up a *Porter* *Cable* 4 1/2 inch Grinder. You just saved my Life 3 times over with your cool work tips!
Great to hear!
This video is superbly comprehensive for both training and safety. Essential viewing for an occasional user of grinders like myself and yes, I did learn a few things. Great stuff.
I'm glad the video helped
Thanks for the comment 👍
I appreciate your focus on proper PPE and proper use of it. I planned to use it before hearing of the Google images; they only underscored the need.
Yeah, you can't be too careful with grinders ;-)
Thanks for the comment 👍
Great video.I went from being scared witless of angle grinders and NEVER using one,to it being my most used tool for all sorts of applications.I now have two Dewalt cordless grinders,inc the Flexvolt,and a 9" Metabo corded.
It is by far the most useful tool ive got.
Thankyou for making me a grinder addict lol !
LOL, they are a superb tool when used properly. I would be lost without mine ;-)
Thanks for the comment
Thanks so much for this! I bought my first angle grinder yesterday--from watching your video I'm now aware of proper usage guidelines. Great stuff!
You are welcome
Thanks for the comment 👍
Brilliant video. Checked my Grinding disc that I came with the grinder, it was 5 years out of date!
Blimey, good job you checked!
Thanks for the comment
Really great video .Super comprehensive. I’ve done a lot of car DIY but never used a grinder. Really thorough safety advice..Thank you👍
Glad it was helpful!
This was great! Bought my first angle grinder today. It feels good to know how real professionals work. Very clear what to do and what not to do.
Thanks for the comment 👍
I work in Occupational Health and Safety. People underestimate the danger of angle grinders, there are horrible incidents that happen daily around the world.
Your suggestion of having people Google the results of the incidents is a great way to open their eyes to the risks...
Thanks Lee ;-)
Thank you for this very informative video. I purchased a angle grinder to sharpen my lawnmower blades and garden tools. Now I know is has many more uses.
I'm glad you found the video useful ;-)
Thanks for the comment
Excellent information regarding specialist disc types. Paint removal disc a very handy tip, must get one now!
