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.
Our black ceramic grade for cutting high hardness metals with Rc 55 and above, chilled cast iron and powdered metals. This insert has replaced some grinding operations in hardened steel (Rc 60-62). Available with hole for pinlock.
