In grinding operations like snagging and cut-off work, the surface finish, and even the metallurgical damage the workpiece, may become relatively unimportant. Wheel life and the rate of cut obtainable then become the criteria of grindability. The best way to determine grindability is to start with the selection of the proper wheel.

Safe operation also involves watching the speed. The RPM rating of the accessory should meet or exceed the RPM rating of the tool. For example, a 7-in. grinding wheel that is worn down to a smaller size should not be used on a 5-in. grinder, because the wheel was not designed to be used at the much higher speed of the smaller tool.
