I need to grind out a small portion of my rear bumper mount to make room for an aftermarket bumper. I noticed that grinder bits are marked as appropriate for a handheld grinder OR a power drill. I already own a drill. Do I need to buy a grinder too? Has anyone tried a small grinding project with just a drill?

 

so long as it isnt a battery powered drill, which spin too slow, it should work out ok, just slower than a pneumatic die grinder, which spin very fast

a good thing to have for hole drilling projects are "stepped drills" in tungsten

 

That is very helpful info. Thank you!

 

If you get a die grinder, get one that has a variable speed and plugs in.

I use this......so does my friend who does cylinder head porting & flow testing on the side.

thanks!

 

You could also get a carbide burr bit, and use your drill. Cheaper than a 250 dollar corded die grinder.

 

That is my plan!

 

I was told to never use those bits in a drill as they are designed to be used at a much higher RPM. The lower RPM will result in chipped teeth.

 

I use them all the time with both, never had an issue. FWIW I'm a welder/fabricator and deal with metal daily

 

I hear ya, I am too. My Snap On dealer told me he wasn’t supposed to warranty any that were broken using a drill.

 

I think what the issue is that with carbide, it does not take impact well. Although I have treated my carbide burrs badly at times. Just use steady with one hand on the front of the drill. Those bits do work better at high speed

 

Sounds like a cheap bastard, lol....used to have a rep like that, my current rep replaces no questions asked

 

I said IF......

 

Wasn't meant as a diss, I'm all about buying new tools, lol...just meant there's cheaper options other than buying a tool you might not use all the time...it's a different animal if you're gonna be using it a lot

 

Agree...I just finally got tired of making do with a drill and took the leap......I also wanted to be able to control the speed with something other than the trigger.

I simply suggested one if he decides to go that route....

A drill will work, but they aren't designed for the kind of side loading it puts on the shaft...the die grinder is.

I don't use mine a lot, but when I do, I am glad I have it.......and you find uses for it you didn't think of when it was bought too......
