Ceramic Inserts are indexable inserts made from Aluminium Oxide Al2O3 or Silicon Nitride Si3N4. They have a hardness of 2,100-2,500 HV (About 40% above carbide), which enables them to machine Hard Steel up to 55 HRC. It can also machine cast iron and nickel-based alloys six times faster compared to coated carbide inserts. Wisker fiber available to get the best toughness.
Triangular Ceramic Inserts with an 11° Positive Flank for Machining Hardened Steel
Black ceramic (Al2O3/TiCN), used for high speed, light roughing and finishing of hardened steel andchilled cast iron.
