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.
Positive 11deg relief ang., M class, square insert, without chipbreaker for finishing to medium cutting
Al2O3 based coated cramic grade for continuous tur ning of ferrous hard materials.
