Zr (Zirconium) is the type of abrasive grain suitable for coarse to medium particle size applications on metal, making it an excellent choice for demanding applications, for example on stainless steel. It works best under high pressure, which is necessary for the grain to break, exposing new sharp edges. It is a type of abrasive that has large fracture planes and self-sharpens during the cut.

E or F papers are the most resistant and least flexible standard paper supports used on the market. They are used in belts, discs and rolls that require high resistance, such as large belts where high breaking strength is required.
