According to Dormer Pramet, the balanced shape of the chipbreaker provides a stable and sharp cutting edge with a large area for chip formation and evacuation from the cutting zone. Also, its positive geometry allows for low radial cutting forces, which also serve to minimise vibration in unstable machining applications.
