SW and FW – Shaft Parts – T9215


Improved Productivity
- Due to uniquely designed wiper edge with radius shape, SW chipbreaker
increases productivity by 1.8 times compared to the competitor’s regular insert without wiper.

Stable machining
- With the competitor’s insert, the operation often has to be stopped because of long chips. On the other hand, SW chipbreaker improves chip control and provides stable machining due to the optimized geometry that allows the feed rate to be increased.
