FB type - Chipbreaker
![](https://www.sumitool.com/en/products/cutting-tools/assets/mt-images/fb.png)
Cutting edge specially designed for chip control
Reduces unexpected fractures, choke stoppages and work damage in pipe steel, rolled steel and low carbon steel.
1. Reduces edge fracture with a ridge.
2. High-raked breaker wall improves chip breaking.
3. Variable rake design within the nose radius increases chip distortion and improves chip breaking.
