SW and FW – Differential Ring – T9225


Improved productivity
- Due to the wiper edge in the innovative geometry, SW chipbreaker increases productivity by 1.3 times compared to the competitor’s wiper insert.Stable machining- With the competitor’s insert, sudden fracture occurs due to chip jamming. SW chipbreaker provides smooth chip control.
