AH905 – Aerospace Parts – AH905


Low cutting force -Sharp land design and unique dots on rake face significantly achieves low cutting force by reducing contact area to chip. HMM chipbreaker offers highly stable chip control. -
Stable tool life -AH905, an ideal grade for superalloy turning, offers stable machining even of the difficult-to-cut materials, which achieves 1.3 times longer tool life than the competitor. This is the best solution for superalloy machining!
