CBN(Cubic Boron Nitride) grade TB100 is specially designed by ToolingBox (Beijing) Industrial Technology Co.,Ltd for cast iron machining with high-speed, such as normal gray cast iron, engine cylinder and cover etc, with 88-94% pure PCBN content (8-12um particle size) in a metallic based binder which greatly helps in dissipating heat.

This CBN material can produce as good or better tolerances than conventional grinding with longer tool life and machining efficiency.

Revolution for milling cast iron material, recommended cutting data: 

Vc up to 1000m/min;

Fz up to 0.5;

Ap max to 4mm;

Better tool life with high effectiveness. Please visit us for more details via www. toolingbox.com
