SUMIBORON Coated SUMIBORON BNC200 Hardened Steel Bearing Steel Excellent wear and fracture resistance Predictable tool life on a wide range of applications General Our silver coloured Sumiboron insert grade BNC200 offers safe reliable cutting and predictable tool life. The newly developed cutting material with enhanced edge strength is coated with TiAlN based ceramic for excellent wear resistance and realises extended tool life even when interrupted cutting. This grade is especially suitable for medium speed machining of carburised surfaces. Predictable tool life Extended tool life is realised even when high speed cutting thanks to excellent wear resistance. Wide range of applications Sumiboron is suitable for a wide range of applications eg. from low to high speed interrupted cutting. The newly developed brazing technology maximises edge strength making Sumiboron suitable for interrupted and continuous cutting.
