00º Sioux-Style Ruby 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 epoxy 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.

Ruby stones are comparable to the original Black & Decker general purpose stones. 11/16"x16 thread.
