Can angle grinders cut wood? The answer is YES...but it can be tricky. This short video from The Honest Carpenter will show you how to cut wood with an angle grinder. It includes several tips and tricks for cutting wood with angle grinders.
Angle grinders are typically used to cut metal and masonry. But those cutting wheels have abrasive edges instead of teeth, so they won't help much if you want to cut wood.
Graff sent me out their new speedcutter blades, which are specifically designed to cut wood with angle grinders. They have 3 tungsten carbide teeth, and a beefy wheel shape.
Angle grinders spin at about 11,000 RPMs. (Circular saws only spin at about 5,000 RPMs.)
They also lack a snap-back guard. They are a freehand tool. This, combined with their excessive speed, makes them a very dangerous tool
When you cut wood with an angle grinder, be sure to keep body parts and clothing AWAY FROM THE BLADE! Let the blade spin down before you set the tool down.
CAN YOU CUT WOOD WITH AN ANGLE GRINDER?? (Tips + Tricks--cutting wood with angle grinders):
1) Set the blade guard low so it protects your fingers.
2) Use the blade guard as a pivot to lower the blade into the wood.
3) Angle grinders cut on the "Pull", so the teeth will engage if you draw the angle grinder towards yourself, cutting through the wood.
4) Thick material will be harder to cut because the angle grinder wood blade is not very big. You may have to flip wood stock to cut all the way through it with an angle grinder.
5) This Graff speedcutter blade is also rated to cut some aerated concrete products. I like to use it to cut hardie plank siding.
6) You can us an angle grinder with woodcutting blade to SHAPE WOOD! Just hold the blade flat and pass it back and forth across your stock--it will pare or gouge away layers of wood.
7) Angle grinders with woodcutting blades can be used to NOTCH wood as well. Just be sure to wear gloves when you create notches in wood with an angle grinder, because it can throw wood chips back at your fingers.
BE SURE TO EXERCISE ALL CAUTION WHEN CUTTING WOOD WITH AN ANGLE GRINDER. UNPLUG THE TOOL WHEN IT'S NOT IN USE, OR BEFORE YOU CHANGE THE BLADE OR ADJUST THE GUARD. WEAR SAFTEY GLASSES, EAR PROTECTION, AND A RESPIRATOR!

As a kid, we had an angle grinder with a sanding disc on it. I put it on my lap and plugged it in. Well, someone had turned it on and, of course, it tore up my legs. So, another tip is to make sure the tool is turned off before plugging it in. Thanks for sharing this video. Great job!
Good thing it only cut your legs, ...... as opposed to other boy things!!!
Another tip is to not put it on your legs
I’ve used these blades for years on aluminum although it had more teeth. Biggest thing I can tell you is find the handle to that grinder. Never use this type of blade without a handle
I’ve never liked using the handle, Brandon. Always felt like two hands were steering from different directions that way. Maybe dewalts handle setup isn’t that good 🤔
I agree that the dewalt handles are not that great. I always used an old school metabo grinder which has a better handle and a spring lock nut for the blade. Again I will say you are correct in saying these blades are dangerous.....some people actually used to call them “suicide” blades. Definitely not a blade for a novice to power tools. Always love you videos man. Keep it up.
@@TheHonestCarpenter you just need to learn how to handle a grinder, a lot of users don't like a handle, but I think they just don't take the time to learn to use. I am a metal fabricator and use a grinder a lot for many things, I have been using many brands over the last 45 years, they are pretty much the same as far as handles go. The only time I have been bitten is when working for someone else and using their grinder with no handle. My feeling is your hand is just too close to what ever blade you have on, no matter if it is a toothed, cutoff, type 27 grinding, buffing, sanding or wire brush.....stay safe, thanks for making this video, watch out for those chainsaw type carving blades, they are really bad about kickback. Cheers from Florida, Paul
That's what helped me today was the handle. I might not have attempted to cut without it.
Handle/no handle, they're going to be dangerous. I'm much more comfortable with a chainsaw.
Thank you for being responsible! You always stress the importance of safety. Not enough tubers do that! Keep up the good work. Really helpful stuff.
There's no such thing as "the importance of safety", when whom wields the power has not earned the discipline required to perform the work. - Zack Massey
Also, he was not responsible. Both elbows were bent while cutting. Stabilizing handle was not used. And you should NEVER use this to notch ANYTHING. But, he referred to Safety first, which is why you you found this helpful. Safety is an imaginary blanket that consumes people with no prior experience in the trade, or task at hand. Earn the right to use this tool, and you'll find that the tool is not dangerous at all. You are the danger.
35 stitches up the front of my leg from this idea. It opened me up like a salad sandwich. Don’t do it. Wood blades should not be used on this tool. Also, the corded model that your using has no safety switch, so the tool will dance all round your workshop, whilst you are bleeding right next to it. Don’t do it!
i also had 35 stitches , very very dangerous tool
Hope you recovered guys, thanks for sharing.
If you just need to cut wood with that ugly finish, just grab the cheapest circular saw........it will do the job way much better.
Thanks for making my day 🤣😂🤣😂
Thank you for posting this! I had the blade in my Amazon cart to buy, but now I know it's not worth the risk. I hope you are ok now.
I'm so happy to see you warning people of the dangers of power tools. It's better to warn than speak too late.. I bought one of these blades because the regular saw blade with multiple teeth scared the crap out of me with kicking. The 3 blades and depth stop seems like a great design. I didn't have rings to fit the larger arbor so will try it when I have them. When something kicks I'm like "Not worth it," whereas before I'd just go for it. Loosing the tip of your finger after drinking and playing with power tools (finger caught in the chain of a DIY electric chopper) gave me a heightened sense of caution and an appreciation to continue playing the piano. I can't imagine the loss of fingers or even a hand. We wouldn't need OSHA if more people cared to warn like you do. So thanks THC!
I tried one of these. As in the film the seem to be fastened with the labelling down. Nasty backcuts all the time. I work mostly with stone though. So I quickly went back to a universal diamond cutting blade and went back to sculpting. The one good thing with the woodcutting blade is that the particles are rather big and doesn't affect your breathing as much, in the long run.
I've been using angle grinders daily for over 30 years and i must confess that i did get lazy regarding safety when using them. Until i had an avoidable accident resulting in a very nasty injury. Now, every single time i pick up a grinder, every time i have respect for the tool. On a side note i recently got rid of my old grinders and got a new modern model with brakes. Game changing in my opinion.
Thanks for sharing this video. I'm confident it has saved me significant injury. No angle grinder wood-cutting for me!
Just got my first angle grinder for a project I'm working on. Your safety tips were appreciated.
Very nice video! Thanks for trying it out! Have a great day and stay safe!

A grinder nearly broke my leg....and my bone 🍖🦴
@@siyabongasibusiso3467 I'm a Millwright... Your statement is only assuming certain scenarios. In the field it's impossible in a lot of situations to do what you suggested.
Had my first experience using a grinder to cut wood. First and last. Scary, scary stuff. Twice (was stupid to keep going after the first) the blade caught and the grinder jumped - fortunately to the side and away from my body. Happy/lucky to have tens fingers and two eyes still. Never again.
Were you cutting on the pull, as the guy says in this video? That sounds okay if the grinder jumps away from your body.
@@craigmcqueen7992 i was. Blade never came anywhere near me to be honest. But spinning, jumping blades always leave me packing my shorts.
@@scottwalton3708 yeah I reckon I would too.
@@craigmcqueen7992 There was a great Stumpy Nubs video on the chainsaw attachment. He was cutting on the pull, didn't lift the tool a fraction of a second before moving it back for the next pass, a tiny error on his part, so the blade DUG IN, the tool spun and ripped up his hand. ua-cam.com/video/x1hf2UILN80/v-deo.html The chainsaw disk doesn't seem all that different to me than the three carbide teeth here. He goes into some detail, I think the biggest issue is how unforgiving the tool is.
Same here
one of the best opening 10 seconds to an informational youtube video I've seen - clear, concise, the topic, the punchline all up front, details follow - well done, kudos!
Thank you! 😄
I can see keeping a saw blade handy for the occasional tough spot that you would otherwise have to use a recip to get to. I’m building a shed soon and can imagine Having an awkward angle or reach. I’ve seen lots of types of saw blades out there with various numbers of teeth available.
thank you, thank you, thank you. be careful is something i hear so often (using my tools to do things they werent made for) but the fact you said it seventeen times makes me sit up and take notice.
thank you very much, i found your advice is fantastic . please continue to create those video that help novice like me. Will continue to watch your video
Thanks for the advice and info. I am a newbie and will definitely follow your advice
man grinders sometimes catch when im cutting concrete with smooth blades. This has an even higher likelihood of catching and you're not using a handle?
Thank you for your video
People spend so much money on redesigning, repurposing angle grinders.
Thank you for stressing how dangerous these are
I think you explained everything very well. Safety first!!!!
More for shaping and rough cuts.
Thanks Michael! That's exactly what I'd use it for. Carefully! :)
Great advice I agree totally, I would definitely only use the grinder for shaping / carving.
Thanks Karl! :)
Use a router. That’s why they make them.
@@dclinks who are you talking to Donald because I unsure what you mean?
I've used a corded grinder (I borough from a friend) once in my life and I was terrified because the thing looks so dangerous. This week I bought myself a cordless milwaukee and I feel so much safe. It has a pressure paddle, so if you let the tool go it will stop, also has an electronic brake, so it stops spinning very quickly and it's only 8500rpm. Of course it is still dangerous, but I feel so much safe. Highly recommend a cordless grinder for someone looking to buy his first grinder. :)
You shouldn't be working with powerful tool if you're so frisky around even an 8.5k rpm grinder,maybe you should consider trades like cattle herding,it's more peaceful. In the past 40 years of using Grinders,I havent had one injury.
I’m about to buy my first angle grinder… a cordless. Scary though.
I was skepticle of a 20 volt circular saw. But I have several B&D 20 volt batteries and the drill Works great ua-cam.com/users/postUgkxjpBI8OOeUXib_iT7UomCrQ-uauwZJ62c . I saw the 4 stars and some glowing reviews so decided to purchase this saw. Well, leave your money in your pocket and run a cord because this little saw won't cut
excellent, instructions and advise to practice safety. Thanks.
I've had my thumb nearly split down the middle due to my carelessness and an old metal disc. This was with the guard and handle on. Angle grinders + toothed saw blades = certain death or even injury!!
Metal cutting discs are bad enough at those speeds. If you're itching to use a 4" wood blade for some weird reason, get a 4" tile cutting machine. You can still do some surface carving with that machine, and its way safer to use.
I use a 4" tile/marble cutting machine with a flat ground wood blade for scoring plywood and other material prone to tearout, before making a full depth pass with a regular circular saw. It's actually easier than reducing/increasing depth on the one circular saw to make 2 passes.
If all I had on hand was an angle grinder with a wood blade for this job, I'd probably go back and get the right tool. If that isn't an option, I'd certainly return the money and go home hungry. Some risks in life are worth taking, but needless risks like these, are not worth anything. 👍
yep i cut my middle finger almost to the bone before i could say ouch. These this are a last resort tool for me
Working on a high end remodel in Seattle I saw a plumber try using one. He wound up with a two inch deep gash in his thigh and a badly slashed wrist. I heard he took four or five months to recover from the wrist injury. Not worth not using the proper tool!!
Super instructions..with lot of caution .Great job..
Very helpful. Thanks! After watching this, I've decided to buy the proper saw. The grinder is too unstable and it won't cut deep enough. Thanks again!
Good thinking, Sean! I’m glad the video was helpful 🙂
Also worth checking a video on an accident while carving wood with an angle grinder to see what can go wrong. It's a different blade but since this blade here is also used for carving wood I thought it is relevant. How you attack the wood when carving matters greatly to your safety.
Thank you, very much Sir. ❤️👍
Hi thank u for sharing this knowledge of grinder cutting wood I was always hesitant from a long time to work with grinder to cut wood😊
- REALLY good info for a beginner. Thanx a million 4 sharing,
Tank's....luar biasa ide anda...sangat berguna bagi orang2.

You can do this with variable angle grinder or speed controller, also you can buy angle grinder bracket so it would look like circular saw.
yeah I'm thinking of getting an angle grinder with a stand since I have limited space and this combo seems like a pretty good idea
Very useful video with many good tips. Thanks.
Hey buddy, thank you so much for the nice video! Loved it! :)
Thank you for your demonstration, If I was cutting the wood , I was using the handle , that is more gripping power and more control on holding the machine , so as long as handle is there , there should be used as a safety reason.
This is a video I really needed! Thank you!
This helped so much. Thanks
Thank you for your safety advice.
Very lovely information thank you
Thanks for the advice. I was pondering that blade for cutting ventilation in an unvented and angled roof soffit. I can't even get a decent shot at it with an angle drill and hole saw, so I've been considering cutting a slit instead, but so far can't find anything to fit. The soffit material is the same as the wood siding, nearly an inch thick and I'm well experienced, but frankly it looks a bit too hairy to attempt on a ladder above my head ... or should I say I wouldn't be too hairy afterward :) ... Anyway, good demo and I'm going to keep pondering!
Use a multi tool
I have spent the last two days watching all your videos. I am so impressed how well you explain things you are so diy guys can understand them. Keep the videos coming. I will probably finish catching up tomorrow.
VARIABLE SPEED CONTROL is what you need. There are angle grinders with a low rpm settings and low power. Just takes a bit
more time but much safer and easier to keep it under control. Might be good to cut hard to reach things like small tree roots. And make sure to cut in such a way that the grinder will move away from you when there is kickback or it blocks etc. A good angle grinder also comes with a extra handle.
I have recently seen for sale a chainsaw disc for angle grinder. It looks lethal but from the advertising video it looks to be mightily powerful at destroying "EVERYTHING" it comes into contact with.
Thanks for excellent safety reminders. 👍👍
I would suggest using a grinder with a paddle switch so you can cut the tool off without removing a hand from the tool. Grinders are awesome for coping crown mouldings.
I hate the ones that just have a switch -- too easy to make mistakes. Paddles all the way.
Thanks this was very good and useful. Plus I like how you explain how dangerous a tool the grinder is
This video is so valuable. Thank You!!!
You’re welcome, Anita!
Very helpful thank you
Two thumbs for stressing safety! However, grinders don't cut while pulling unless you're handling them backwards. Grinders, like most tools cut throwing all the waste away from you. I use it plenty for welding applications and for cutting tiles. If you need something that looks like a grinder to cut wood, I suggest getting the Dremmel Saw Max. For near a $100 you get the saw, four disks for different applications (wood cutting, metal cutting, flush wood cutting and tile glue removal) a support handle and a carrying/storage bag. I have to grinders which I use one for cutting metal and tiles, the other one for actual grinding metal. If I'm cutting just a piece of wood and I don't want to pull out neither the table saw nor the miter saw, I get the Dremmel Saw Max or the Multi-tool (you call it the multi-purpose). Avoid an accident; don't use the grinder to cut wood.
Then you are using it the wrong way because grinders throw waste at you if used in the correct direction.
I think what you want is a COMPACT CIRCULAR SAW. They are smaller circular saws with an angle grinder form factor, but much safer for wood projects.
Perfect video
Skill is very important here.. 👍
2 things for your consideration, 1 Stumpy Nubs did a video about 3 weeks ago where he was using an angle grinder to carve wood, instead of this blade he had the blade with chainsaw teeth. It grabbed and he will be healing for some time. Second and more important, angle grinders come with support handle, use unless it prevents you from getting the job done.
I had no idea that had happened, Bryan. A couple people have mentioned it. It's terrible to hear, and it shows just how dangerous grinders with aggressive blades can be. I like the handle for buffing and grinding applications, but for anything like cutting, I don't want to use it. One hand can overtake the other in terms of force, and you can push your blade off-center too easily. That's how guaranteed bind happens, and on a toothed blade this strong, it'll kick in an instant. I want both hands BEHIND the guard, and pulling/pushing in the exact same direction. Far less chance of twisting the blade this way, and both hands will remain behind the swing arc of a blade spinning out. I suppose it's personal preference though. No matter what, you need to be careful with these things, which I hope I drove home enough during the video.
I will not be cutting wood again any time soon with my angle grinder, except maybe under very controlled conditions as you show. I had a tree root coming from under a concrete foundation which I could not get anything like a chain saw onto. Then I saw a wood cutting blade in the hardware shop, basically a coarse saw blade and thought aha - just the thing. Access was difficult, I could only use one hand. First contact, that grinder flew out of my hand and straight into my leg. I was wearing heavy gumboots but still that thing cut through them and into my leg. Luckily the blade grabbed the boots and that changed its direction, but not before chewing a 5mm wide 50mm long gash right over my shin bone. So yes, I broke more than one safety rule, like not being able to hold it securely and using it for something I should not have. And PPE - without those boots it would have cut to the bone. Also one big problem with these angle grinders is that power is locked on. If anything like that happens it does not lose power when you let it go, even when it does go flying. It has given me a new respect for safety on this device which I already knew had to be used with care.
I think I'll stick with my circular saw or jig saw for lighter work. I watched your video about circ saw kickback and I feel safer knowing it has a sliding guard and soleplate. The angle grinder only has my wrist for stability with the potential for blade binding and an always partially exposed blade. A kickback from it could be disastrous. I love it, but I'll keep it for grinding.
I’m scared of them so I stay away.
Useful tips.
When cutting woods with angle grinder, I use speed controller. It’s safer and more convenient that way.
There is variable speed grinder, i'm using it, it is more safe
Standard AC grinders don't like that (the speed control) as they need the air flow to cool.
@@stanimir4197 based on my experience, i can't cut lots of wood with angle grinder with or without the speed controller as it's not very comfortable to cut wood with it, i would prefer a jig saw or a real circular saw which are more convivence and produce a lot better result . :)
@@backyard.craftsman me too.
Thank you for this
Very helpful. One thing I didn't find clear: were you using the woodcutting disk when you were shaping the wood, or did you switch to something else?
Thanks for the informative video.
Wow your method is amazing im going to try it on because my circular saw Give Up!! i have a Hart 20v Angle grinder!! Does it fit all model grinders???
Nice vlog! I have no match idea about these tools. Can an angle grinder blde be attached to saw tool or unit?
I got one of these. Had a kickback and nearly ripped half my face off, I got lucky but it won't get used again!
Hi.nice blades. Great video's. See more thing's, soon. Learned to be professional. Too.
Great video.👊🏾💯
I use a circular chainsaw blade on my grinder for wood carving/shaping.
Enjoyed the video Ethan. That's a nice blade and can be used for many cutting applications such as the Hardy board siding. As you said and can't stress enough it is a dangerous tool especially with a blade like that or the more aggressive blades that are available. You may have seen Stumpy Nubs video of him about losing his fingers and or hand. Check out his video if you haven't seen it. Thanks for taking the time to produce the video. Y'all stay well and God bless
Thanks Ron! I’ve seen his videos come up before. I’m going to check it out. Take care.
They don't call him Stumpy Nubs for nothing.
Excellent
Thanks a lot. I was considering to buy a circular saw to make mortise and tenon for only 1 project. Now I feel more confident to use my grinder.
Thank you, that’s a risky endeavor indeed!
No wood blades in my side grinder!!! Thank you for sharing!!👍👍
Fuih, good advice. Thanks.
Do you recommend Reciprocating saw for wood and metal? How many watts should it have at least?
very helpful thanks, after washing this, I lost two fingers, before it was five fingers, so great progress.
How many fingers are you holding up now 🖕🏼 haha
I got a lot of long branches and wanted to use a angle grinder but I think I will go on a course first before buying and using one ..
I have this 5 teeth version.
Same high kick back.
But I have speed variable 125mm Angle Grinder.
Lets say im cutting a big sheet of MDF wood and it grabs, is it a bad time or can i hold it n jam it
This blade design answers my question about Dremel's 4" saw, which also spins fast and uses a wood blade with few teeth.
Hi your videos are really interesting. I am a beginner and would like to know what tools to buy as a beginner. Mostly for making tables, chair, etc
Grinders I've used too easily lock in the on position. Putting a blade like that on a rotating cutting tool that will keep running after it leaves my hands isn't something I have interest in using. And I'm a 'safety second' kind of person.
Paddle switch grinders only.. the only most jobsites allow.. should be the same for homeowners
Thanks! 👍🤩
thank you very much
Actually there are many ways this can go wrong..but eventually i have used my stanley grinder to cut wooden pallets of 8mm with no issue.
So my guess would be that u can cut 16mm of wood easily with angle grinders(working from both sides)
I have a chop attachment for the grinder and this is safe for cutting wood with a suitable blade.
Very informative, thank you!
Thanks a lot
Thanks Ethan, I’ve always wandered if this was possible. FYI, the affiliate links aren’t working
Thanks for the heads up Clinton! I got them fixed :)
It looks like it would be a good stump grinder for small stumps that only need a little material removed. Say, to lower a stump in order to mow over it.
Looks good at making stumps out of fingers.
Good tip, dirch this kind of grinder !! Use a paddle trigger which doesnt lock on. That way if you get a bad kick back and lose control you can just drop the thing itl stop itself.
After reading these comments I’m not even going to try it lmao great example of learning from others mistakes.
Most important thing when using grinders is to understand what makes them kick back and to make sure it will only kick back away from you. Kickback happens, but if you're ready for it, then it's not really that dangerous.
Excellent instructions. I have this exact blade for my 125mm grinder, tried to cut small wood but the teeth got caught and the wood flung away from me. Maybe I needed a much better way of securing the wood instead of just stepping it with my foot.
My grinder is pretty safe with button trigger instead of a switch as it stops as soon as I let go of it.
Please be safe, don't cut like that, you risk losing balance and may cut yourself.
A few days ago I injured myself just a little bit, with brand new grinder.
Put a wire brush wheel on (figured its safer than a disk), has variable speed so I set it on 1 out of 6 (around 3000rpm), turned it on and forgot to put gloves and one finger was close to the wire brush and it bruised my finger a little bit. Had it been on highest speed, who knows what injury could have been. This was just one sec of not paying attention.
My button trigger has click to run and also can be blocked, so doesn't seem very safe to me. In case of injury, it may continue to run.
It's also very close to front of grinder, no idea why.
Initially I didn't mount the wheel guard in the correct position, I had it upside down and it was not tilted properly, this is why my finger could touch an exposed area of the brush.
I have a variable speed angle grinder and i use it with the handle. 11 thousand rpm is way too much and dangerous too. I suggest to use a variable speed angle grinder, use it always with the handle and the guard installed
I have an angle grinder with variable speed. Can I lower the speed and cut wood?
I’ll be buying one
I use metal cutting wheel to cut wood in demolition. It will be charcoaled, but is fast.
This video confirmed my opinion I had before watching the video... never cut wood with a grinder...
umm..food for though.
Go back to school
@@lazarusramaube8291 whats that supposed to mean?
Can it be used on a ryboi
See ive been curious about these blades for my grinder. I do alot of floor replacement and i can never get close enough to the wall to remove the rotted subfloor. I think a tool like this being careful would be great. Ive seen a chainsaw style blade for the grinder but i feel like if loose some fingers if it bit to hard in the floor. Definitely scary stuff.
I know I’m late, but you can get these tools. I’m not sure what there called I call them multi cutters. It’s like an angle grinder but with 2 blades that spin opposite. So there’s no grab, like they don’t grip to the wood and pull off in any particular direction.
This is the tool you want.
I would agree with Scotty B, the lack of support and precession effect from the grinder along with the softness of wood - giving it a tendency to grip the blade makes this attachment potentially dangerous. Chainsaw blades are already banned in the UK (England) and these should be too.
An angle grinder just spins to fast for this accessory, use a jig saw in my opinion.
nah, this one way more safety than a chainsaw disk. But angle grinder is very dangerous tool itself. IMO this 3-teeth disk must be used only on a grinder with handle and a handle should be placed only in a side hole (not central hole) to hold it in the way the grinder will run away from you if disk is jammed (there is no handle in the video)
Thats not saying much since just about everything is banned in the UK. Soon They will have to start cutting the points off of chopsticks, Its basically a country full of slaves.
