Depending on the size and model of the bench grinder, you can purchase grinding wheels of multiple grits, wire wheels, cutting wheels, and polishing wheels.

Check your manual to find the proper ratings, torque settings, and tools required for maintenance. These can vary from model to model and manufacturer to manufacturer. 

Always wear safety glasses when using a bench grinder.

Warnings
Never exceed the recommended torque when tightening the bolt securing the wheel. Doing so may result in damage to the wheel which could cause the wheel to come apart during normal operation.
