60º Sioux-Style General Purpose Valve Seat Stones
Goodson valve seat wheels are built to grind accurately and outlast the competition. We use brass bushing to resist galling or seizing to the holder. Heat-cured, permanent expoxy bonding prevents loose bushings. Our bushings are deep set to expose the most abrasive for long life. Each wheel is pre-trued and checked to assure accurate, vibration-free grinding. General Purpose stones are used to remove material from cast-iron seats or inserts. Ideal for antiques. 11/16" x 16 thread.
