DoTwistBall – Planetary Carrier – AH3135


Long tool life and high productivity
- After being switched from shoulder mill to DoTwistBall with HJ chipbreaker, the total machining time has decreased by 25%. Thanks to DoTwistBall’s excellent chip evacuation, chip re- cutting is eliminated, thus doubling the tool life compared to the shoulder mill.
