Thread: Buffing with a dremel

They're for small stuff I reckon (both models), you could make a 50mm dia. buffer for it but even that may strain the motor when used for a long time. 10mm steel, don't think so, sounds like you need an angle grinder and a variable speed one at that.

Didn't even know variable speed angle grinders existed

As for cutting 10mm steel with a dremel, not a snowball's chance in hell. You'll fry the motor in no time.

Should be fine for small buffing but a large wheel may need more power than it can give. Probably be hard to control as well unless it's perfectly balanced.

I was going to buy an angle grinder as I sometimes find myself needing to cut small amounts of metal, and I thought maybe as it's only small stuff I could get away with a dremel.

Do people use those buffing clothes that attach to their drill, or do it by hand?

Used the drill mounted buffers with success. It's easiest in a lathe but a drill press or other fixed drill should work a treat.

You should be able to find something like this. I use these on my
RC sailboats and they work great. I use a hand drill, but a drill
press would work as well.

Unless the boxes are very small the Dremel would be a strain
on you as well as the tool.

For Dremel cutting sheet steel, I'd say about 1.5mm maximum. Round bar, smooth or threaded, 5-6mm. Either way, buy cutoff wheels by the ton.

Dremel buffing with a 3/4" wheel can remove CA. BTDT.
