1. Built to perform at higher machining conditions

Strong and thick insert corner is designed to withstand fracturing force during high feed operations


Thick insert corner Max. 10% thicker than competitors



M2 screws reduce screw neck shears under high cutting forces. A larger screw enhances insert’s fixation and easy handling.

2. Positive inclination angle of the insert provides smooth chip evacuation

The positive cutting edge position contributes to a controlled chip formation and easy chip evacuation when machining next to shoulder and slotting operation



Positive inclination angle



3. Designed with a small entry angle for chatter stability, TungForceFeed’s insert significantly improves efficiency and tool life even when machining in long reach areas
