Supposedly, the wheel will eventually break apart at speed. I've never actually heard of an incident, but have been warned about it many times. I think the aluminum melts into the pores of the wheel, then expands and contracts as it heats and cools, causing the wheel to crack. At 3500 rpm, it's going about 60 mph.. I wouldn't want to take any chances In case anyone isn’t aware… never grind aluminum on this type of grinding wheel. Supposedly, the wheel will eventually break apart at speed.
