Excellent 0.4μm fine grain cemented carbide material is selected to ensure the stability of the material from batch to batch.

Suitable for complex working conditions and machining of medium and high hardness materials with excellent wear resistance.

The groove shape is strictly controlled and matched with high rigidity structure to obtain good wear resistance and chipping resistance, which can meet the cutting of a wide range of materials such as 316, 304 stainless steel, titanium alloys and hardened steel.

High precision tolerance, quality control.

Recommended emulsion or oil coolant.

Semi-finishing and finishing.
