I’m new to bench grinding. My first power grinder is on its way (Rikon 80-808) but I’m unclear about the included wheels. They are white aluminum oxide in two different grits. I’ll be using this grinder to put a hollow ground bevel on chisels and plane irons. My understanding from Asa’s Bench Grinder Basics video is that a “friable” wheel is preferable. Neither Rikon’s online specs nor the downloadable user manual for this grinder specify whether the wheels are friable or not.
Anyone know if all aluminum oxide wheels are friable by nature, or do I need to find an aftermarket wheel that is friable to replace the stock ones on the Rikon?
