1. CBN (Cubic Boron Nitride) sintered alloy is second hardest material next to diamond as right figure, 3 times harder than Tungsten carbide, moreover having features of strong heat-resistance and high thermal conductivity. However, less tough characteristic of CBN often causes chipping of tool edge easily. Accordingly, CBN is recommended for finishing of hard materials with less cutting load on the tool edge, which guarantees extra-long tool life.

2. CBN End Mill has low affinity with iron-based metal,so it can be used for the high speed cutting of iron-based metal,CBN End Mill high precision & surface finished,cutting speed is 10 times than carbide,CBN End Mill hardness& wear resistance is 50 times than carbide cutting tool ,25 times than ceramic tool.
