Features
1. Grade properties
- BXA30: Ultra-fine cBN grain uniquely designed for superior adhesion with the PVD coating provides exceptional wear resistance and eliminates built-up edge, delivering excellent surface quality and tool life predictability.
- BXA40: Thanks to the cBN substrate being formulated for superior adhesion with the coating, edge chipping is significantly reduced for extended tool life during interrupted cuts using extremely light depths-of-cut and low feed rates.
