The resin-based core, available for round tool grinding, is over 75% lighter and eliminates the risk of sparks while reducing chipping, breakage and chatter, for better finishing in round tool applications. The Paradigm bond, which combines the wear resistance of a metal bonded wheel with the ease of profiling in a vitrified bonded wheel, has up to 46% porosity enabling improved coolant flow for cooler cutting and reduced part burning, allowing for truing and dressing.
