New Product News WffliKJfrM Small-diameter end mill for hardened steel cutting Mold Parts making processing Evolution Hard for cuttiing hardened steel! Extensive lineup of wider coverage in small-diameter range! Hitachi Tool Engineering, Ltd.

Features of Epoch Deep Ball Evolution Hard When cutting hardened steels, these tools provide particularly long tool life to enable stable cuttiing. Makes processing possible without electro-discharge machining and reduces polishing time. Flank face Forming the flank surface to consist of two surfaces results in the first surface suppressing wear. Wear progress direction rIK»|-jp Compound I TYsAAs neck shape Back draft effect Backdraft effect enables good-quality processed surfaces to be achieved. Inherits the reliable backdraft shape to enable chattering to be reduced by performing point We combined...
