TetraForce-Cut- Clutch Parts – AH725


High productivity
– The current tool was inferior in surface quality because of chip scratching, that required 3 pass in total including finishing. On the other hand, TetraCut with unique three-dimensional chipbreaker achieved outstanding chip control and much better surface only with 1 pass! Thus, TetraCut successfully shortened machining time by 1 / 3 compared to the current item.

Longer tool life
-TetraCut with AH725 has high wear resistance. As a result, 1.7 times longer tool life were achieved against competitors’s one!
