Thank-you for your demo, I have seen Die Grinders in tool shops and tool catalogue but because I never knew what they were used for I never gave them a second thought. N.
Wow, a twist drill would work just fine but it would be best in a mill or drill press to control the feed. You can also use a step drill / unitbit as these are great at enlarging drill holes. Die grinders don't do much of anything well, it's just that sometimes they're the only way to get at something difficult to access.
Perhaps the manufacturers ripped me off when I bought the hardened steel shackle. Anyway I tried a blacksmiths drill bit first and it would not enlarge the hole- because its hardened steel, hence I had no option but to use the die grinder ;-)
A bit more metal experience would help you immensely Kevin.. IE; Laser or plasma cut holes as we find in most mass produced brackets and such are hardened around the holes because of the heat involved to cut the hole. We use die grinders all the time to enlarge or smooth a CNC torch cut hole as normal drill bits are useless in these situations.
You can grind a curve with one, but it might be difficult and time consuming. You could do it using an angle grinder though- ua-cam.com/video/XSwLrPMWtHg/v-deo.html
It was too hot to touch for a few minutes. The grinding wheel I was using was a little too large for the hole I was enlarging, which made it difficult to enlarge. Thanks for the comment
coming from an M.E. we use carbide drills all the time to drill hardened steel. I would recommend the hp carbide drills from OSG. they are cheap, well made, and coolant thru
I have spent some money one dremel tools and accessories.. And the dremel has a lot of flaws. Yes it'd light and compact but removing and installing bits takes some time. The cutting wheels can easily break. Can you get cutting wheels for this? Then it could easily replace the dremel tool as the buts seem sturdier
It was slightly worn, but you should be able to do a few jobs from the one bit- especially if you use a carbide bit as they last a lot longer. Thanks for the comment
This is a good demo about the capabilities of die grinders. On a side note, do you think tempering the hardened steel with a torch would have made drilling the hole easier? (assuming paint was removed). Also, do you think tempering it would make it possible to drill with a HSS drill bit using a drill press? Thanks.
Just wanted to ask, can a die grinder be used to enlarge/cut a hole in plastic. I'm planning to make a semi circle at the base of my bumper so the muffler tip can slide through and sit in place. I'm aware that the size of the bit will not meet my requirements but was just wondering if I could use the edge and slowly carve a semi circle until I get the radius that I seek. The bumper is made from flexible plastic and is very thin btw
Hey I install storage units and some times I have to cut in 18 gage metal it install a beam threw the wall for the floor I normally use a angled grinder but can no longer use to to management so I currently use my snips but its to much time consuming so can I use a die grinder and if so what bit can I use to to make plunge cuts in the letter of a Z thank-you
+David Cordero You might struggle controlling it. I have never tried to plunge cut anything with one of these. I normally use them for deburring or enlarging small holes in hardened steel (if the metal is not hardened I use a drill as it's easier).
+David Cordero Not sure. Have you ever tried to use a router free hand? they tend to be difficult to control as they try to move in the direction of rotation. I don't want you buying something that won't do the job as these tools are not cheap. If you can wait a few weeks I'll have a try when I get time?
Yolanda Sinclair A die grinder revolves at a much higher speed than a drill, so you can use it for grinding as in this video where it was used to grind the hole larger in the hardened steel shackle. You could not do that with a drill. Thanks for the comment ;-)
***** Ok, thanks. By the way, I love your videos, some things really helpful, some things I'll never need (like this one) but always really clear and interesting. Thank you
Tungsten burrs work best on steel, they throw off hot chips in your face though. The heads are brazed onto the shaft, if you press to hard they can break off.
Hi, I really enjoy you videos but why not use a masonry bit? *EDIT:* Oops, I see where someone else made the same suggestion. There are videos on youtube showing it being done. The main thing I use my die grinder for is sharpening my mower blades - works a treat ;-).
MakingTheCut It's a pain in the arse sometimes that auto correct! I have only used a Dremel once and it was not much good to be honest, they are OK for model makers but for doing something like this in hardened steel I think you would use a few abrasive bits doing it. Thanks for the comments
Hiya mate, great video. I've got a quick question. I've just recently bought a Makita screwdriver/bit set and there are two little things labelled 'Plastic Finder', they are like a small plastic tube with a spring loaded washer/clip inside. What are they for? Cheers mate....
I think they slide over the screwdriver bit and hold the screw onto it- they might be useful when driving in slotted screws which are difficult using a drill/driver.
at 02:00. the solution is quite simple, drill them using bits meant for concrete. you can drill up to 5-7 holes with the concrete drill bit upto 21mm in depth( heavy duty leaf springs) and they are quite cheap
i won't be posting such videos, because wasting materials just to show you guys is out of my reach here (unless i'm doing something which requires this process, but i surely won't focus on filming it because i'm not familliar with camera etc) because i live in Mauritius and everything is scarce, and i'm just a hobbyist looking for the cheapest alternatives. Anyway thanks for the reply.

@@ultimatehandyman This looks like the Dremel tool I use in the US

What’s the name of the electric die grinder you are using
Not sure of the model number, but it’s just a Bosch 110v die grinder 👍
I came here hoping for a bigger hole.... I've got a really scruffy 3 cm hole that I want to tidy up..... any tips?
If it is not hardened steel, perhaps you could use a step drill?
Thanks for the comment 👍
I have three electric die grinders with a Key chuck at the end they work awesome
👍
Can u cut a curve using die grinders? For kitchen knives.
You can grind a curve with one, but it might be difficult and time consuming.
You could do it using an angle grinder though- ua-cam.com/video/XSwLrPMWtHg/v-deo.html
2:43 grinder porn. literally
😂😂😂😂
Not just me with the dirty mind then lmao.
@@jameznm me too.
@rockthestrand I’ve never laughed like this 😂
Silly question perhaps, but just wondering how hot was the bracket after you enlarged the hole?
It was too hot to touch for a few minutes.
The grinding wheel I was using was a little too large for the hole I was enlarging, which made it difficult to enlarge.

can u grind down a steel screw head with this i have one in a hole that i cant get to with other tools without destroying the wood
Yes, just be careful of touching the sides of the hole, as the die grinder can grab!
Thanks for the comment
Thanks for the video, a great talk through also, brilliant.
I have spent some money one dremel tools and accessories.. And the dremel has a lot of flaws. Yes it'd light and compact but removing and installing bits takes some time. The cutting wheels can easily break.
Can you get cutting wheels for this? Then it could easily replace the dremel tool as the buts seem sturdier
Yes, you can get cut off wheels for them although I have never used one yet.
Thanks for the comment
Awesome video! Was the bit/burr worn down from just this one job? Or will one bit/burr last for many jobs such as these?
It was slightly worn, but you should be able to do a few jobs from the one bit- especially if you use a carbide bit as they last a lot longer.
Thanks for the comment

Tempering it might have helped, although if it has an high carbon content a normal HSS drill bit would probably soon dull.
Thanks for the comment ;-)
***** Thanks!
You are welcome ;-)
is there any other way to grind away hardened steel like on a bench grinder? I need to remove a fair bit of material on a high carbon steel knife
Yes any kind of grinder/abrasive machine should work on hardened steel.
Thanks for the comment
Just curious .. .can an electric drill achieve the same results using the same bits? Thanks!
No, I'm afraid a drill does not rotate fast enough. Die grinders rotate at over 10,000 RPM
Thanks for the comment

Yes it can, but a drill might be easier with a rotary burr as the die grinder might be too aggressive for plastic.

Ok cool thank-you do you think if I make a hole first that I can still make a Z like pattern

+David Cordero If you can use snips, why not use electric shears? They make both corded and cordless.
Shears r no good I pretty much needed a machine that would allow me to make plunge cuts into metal and the grinder makes to much of a cut lol
What is the difference between a die grinder and a drill? Thanks

What do you do so it doesn’t helicopter on you?
A smaller diameter bit can help to prevent it from doing that, but even then you have to be careful.

can i use this to cut thick steel
It's not really good at cutting steel, but is good at filing it away.
Great product especially for the price
🤔
There very common here in the US .. I use mine a ton !!
Thanks for the comment ;-)
what is the bit? Aluminum oxide?
I think they are made from either aluminium oxide or silicon carbide.
Good video, thanks. I'm in an almost identical situation. Also, good joke at 2:53
You are welcome
Thanks for the comment
Brian Boru you need to fill in the hole
Why wouldn't you use a deemed or put the bit in a drill?
Sorry, I do not know what a deemed is?
The bits won't work so well in a drill as they do not run fast enough.
Thanks for the comment
I meant dremel tool, the auto correct changed it,

It's a pain in the arse sometimes that auto correct!

Hi - anyone have any idea what make those safety glasses are?
Rambo Rees They are Honeywell Millenia fave.co/1NzUtuh
Took a similar job down my local Electro Discharge Machine factory for a small job fee. Would use them again.
Thanks for the comment 👍
Thank-you very much appreciated
I thought an asp was a snake. Anyway, just messing, love your content UH. Greetings from the North, but not quite that far (Yorkshire).
Yorkshire is a great place ;-)
Thanks for the comment 👍
and the heat from it didn't effect the hardened steel???
No, the small amount of heat generated is unlikely to alter the properties of the steel.
Thanks for the comment
It's a giant Dremel!
Why didn't you use a brill bit
The shackle is hardened steel, which is very difficult to drill and requires special drill bits that are not normally available in such a large size.
Hiya mate, great video. I've got a quick question. I've just recently bought a Makita screwdriver/bit set and there are two little things labelled 'Plastic Finder', they are like a small plastic tube with a spring loaded washer/clip inside. What are they for? Cheers mate....

cheers mate. I thought it was something along those lines, i'll give em a go but i will probably cope without em....

+Arjoonmoal
Can you upload it to UA-cam and post the link here?
8 minutes wow that seems a long time just for that.
I know. He could have sat and watch two Adelle videos in that time - what a waste!
i have this exact issue and driling will be a pain
Drilling hardened steel is very difficult, without really expensive drill bits or specialist equipment.
Best of luck with it 👍
Is it me or did that whole sequence with the grinder going in and out look kinky ?
It's you LOL
Clempt90 I was thinking the same thing, lol!
@2:47 lol oh yeah!!!!
***** what's the top speed in RPM on the angle grinder.
Die grinders run at very fast speeds, generally between 15,000 and 26,000 RPM. I'm not sure of the exact speed of that die grinder without checking.

Just use a 20 quid air grinder or drill !
Some of the air grinders have smaller shanks.
Hard as a tom cats head!
8 minutes 😳 bro you need double cut carbide burrs !!!!
