[quote=”wafrederick” post=159232]There is a drawback with the roloc discs used on a die grinder.The roloc discs on a die grinder can do damage,this is when cleaning gasket surfaces used on a die grinder.GM has a TSB on this not to use them.The little pieces can get in the oil which the oil filter can’t trap can cause premature engine failure.There have been cases of this happening including the use of scotchbrite pads.[/quote]
Can you use them on brake drums and rotors? Especially on the hat portion that’s in contact with the hub assembly that’s usually rusted? I just ordered an Astro Pneumatic angle and straight die grinder plus some coarse 3m roloc discs and a 3m roloc holder. thanks
