BNC2010 and BNC2020 are the latest additions to the coated SUMIBORON series, to provide even better stability and longer tool life for hardened steel machining. BNC2010 grade for high precision hard turning applicable for finishing requiring good surface roughness and dimensional accuracy. BNC2020 grade for general hard turning covers a wide application range. BNC300 grade for interrupted hard turning which work piece has mixture of continuous and interrupted part. New edges expand our line-up of CBN grades.
