Not to be picky Jack21, but carbide IS non-ferrous. Tool steel is ferrous. Ferrous meaning iron content.

Try hitting the bit with a bar of soap before you try cutting aluminum. Works pretty well. Just have to keep doing it or it will load up. There are also some solutions available to dip the bit in for non-ferrous work such as aluminum, brass copper etc. I quit using tool steel years ago Gets dull too fast.

Also, using the grinder at full speed makes a smaller chip and is less likely to clog. It also makes a much smoother cut.

Mine is a Craftsman. Never had a lick of trouble with it. 26,000rpm
