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.
Advantages
l Predictable tool life!
Extended tool life is realised even when high speed cutting thanks to excellent wear
resistance.
l Wide range of applications!
Sumiboron is suitable for a wide range of applications eg. from low to high speed
interrupted cutting.
l The newly developed brazing technology maximises edge strength making Sumiboron
suitable for interrupted and continuous cutting.
