Gear Cutter Materials

Gear Cutter Materials - High speed steel is used almost exclusively as the material for making, cutting edges of gear cutting tools. The steels most widely used are the general purpose grades. The more highly alloyed grades of high speed steel arc recommended only for conditions where greater red hardness is necessary.

Such conditions include hard work metal, inadequate supply of cutting fluid or high cutting speeds. Cutters are made from these highly alloyed grades only when one of the general purpose grades have proved in adequate. Carbide cutters have been tried for a variety of gear cutting applications, but they have proved uneconomical in all but a few applications.
