• Silicon carbide, generally used for non-ferrous metals

• Aluminium oxide or alumina, the most widely used abrasive, generally used for ferrous alloys, high tensile materials and wood.

• Diamond, most often used in ceramic grinding or final polishing due to high hardness and cost

• Cubic boron nitride (CBN)

• Garnet, usually used for machining of wood.

• Zirconia/Alumina alloys, suited to carbon and stainless steels and welds

• Glass, usually used for pressure blasting operations.
