A synthetic or man-made diamond material is now available which is extremely tough with a hardness approaching that of natural diamond. A layer of this synthetic diamond material is bonded to a tough shock-resisting base of cemented carbide for use in the form of tips. The range of application is on non-ferrous metals such as aluminium alloys, magnesium alloys, copper, brass, bronze and zinc alloys and non-metallic materials such as ceramics, porcelain and plastics. This material will also machine fully sintered tungsten carbide. 

Manufacturers offer diamond cut-off wheels with metal bonding (bronze or nickel) and resin bonding. Cut-off wheels with resin bonds have proven effective for hard ceramics, e.g., hot-pressed silicon nitride. Aside from their relatively high rate of wear, they are sensitive to tilting of the sample during sectioning. Cut-off wheels with metal bonding are predominantly used with oxide ceramics.
