EDGEV Solid CBN (Polycrystalline Cubic Boron Nitride)
Solid CBN is made from HBN sintered under the process of supper high temperature and supper high press, the hardness approach the PCD cutting tools. These are chemistry and hot stability and high wear resistant than others cutting tool.

ESBN500 90%CBN
Wear resistance, impact resistance, and economy. Apply to the high-speed cutting of the gray cast-iron, spheroidal graphite cast iron workpieces. Suitable for medium-high-speed cutting of the alloy steel. Semisteel.
