Guidance for SUMIBORON GradesSUMIBORON

HARDENED STEEL MACHINING

(2)

Applications Coated SUMIBORON: 1st recommendation for hardened steel machining, best performance in high speed and efficiency machining. Uncoated SUMIBORON: Optimal for machining small items with a limited cutting speed and hardened steel.

Series Applications 300
