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...
