Depending on the model, grinders are supplied with one or two aluminous oxide stones. Stones have two grades, fine for hard
materials and coarse for soft materials.
When grinding, should surface of the stone become "loaded" (coated with particles of the material being ground) it is probably the
wrong grade of stone for the job.
IMPORTANT: Grinding stones MUST ONLy be assembled by a person holding a grinding wheel certificate.
