High quality tooling balls provide a precise reference point for critical machining operations. Available with slip fit or light press fit shank diameters.
1144 steel heat treated to 53-57 RC
Weld between ball and shank is designed so the ball will fall off if subject to unusually heavy lateral force, preventing set up and inspection errors that may occur because of a bent shaft.
