AH905 – Aerospace Parts – AH905


High productivity - Specified grade for Superalloy “HMM chip breaker” significantly reduce the contact area with the chips. Specifically, that can be 220% improvement in machining efficiency than the current items. Stabilization - An insert of smooth surface prevents chip adhesion and improves chip flow. Thus, AH905 offers 1.3 times longer tool life than competitors!
