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

High feedProfilingShoulder millingShoulder milling RFace millingSlottingSlotting RRampingPocketingPlungingHole 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
