Question Die Grinder Bits

First off, whats up everyone. Been a while since I came on here and i'm back for a few reasons. One being that most people on here are older more smarter people. (no offense lol)

What kind of die grinder bits do you use to "grind" cast aluminum? And stainless steel? I've tried some bits I got from my buddy, and the stainless ripped all the "teeth" off the bit.... The die grinders I bought came with stone polishers or something, and they looked too weak for stainless or even the cast aluminum. If anyone could link to bits that would withstand the cast aluminum, that'd be awesome. Thanks.

I don't think you quite understand how the bits are used.There are specific "burrs and stones" for aluminum and cast iron/steel.Generally the stones are color coded as what they are used for.Black silicone oxide is used for aluminium and white or grey aluminum oxide is used for cast iron or steel.Stones are used for shaping and smoothing.Burrs on the other hand are used for rapid removal of material.For aluminum work I use a cutting lube to keep the burr from loading up.The lube is like a wax that keeps the aluminum from sticking to the burr teeth or "flutes".
