There is great demand for superabrasive wheels that have the durability of metal bonds but the free cutting action of resin bonds. These wheels must be durable with extended life and be self-truing and self-dressing in order to provide performance over long periods of heavy use.

Vitrified-bond technology is today's answer. A vitrified bond is actually a ceramic bond. It is extremely hard, yet free cutting, and combines the better characteristics of both resin and metal bonds. It provides a longer tool life, effective grinding, and high productivity, which provides maximum performance with minimum maintenance.
