TungForceFeed

Small-diameter high-feed milling cutter with robust design for stability and efficiency

Indexable high-feed milling cutter, available in as small as ø8 mm diameter, offers free cutting and effective chip control in a wide range of applications

Applications & Features

Applications

Profiling Shoulder milling Shoulder milling R Face milling Slotting Slotting R Ramping Pocketing Plunging Hole enlarging

Features

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
