The cutting surface must be harder than the material that it will be cutting. That can mean that the teeth of a sawblade might be made from carbide steel, coated with diamond dust or that a drill bit may be made from tungsten carbide, which are both stronger than steel alone. Reducing the heat from friction while cutting by using some fluid medium usually extends the cutting life of whatever is being used.
