AH905 – Aerospace Parts – AH905


Stable and longer tool life - The combination of HMM chipbreaker and AH905 grade provides high performance due to excellent chip control and high fracture resistance. AH905 grade with PremiumTec reduces chip adhesion on cutting edges, providing 1.5 times longer tool life than the competitor without sudden fracture. AH905 is the great solution for superalloy machining!
