(mm/rev) NFB Chipbreaker for Finishing NLB Chipbreaker for Light Cutting The NFB type for finishing and the NLB type for light cutting have been added to the chipbreaker series for low carbon and general steel machining in addition to the already present NLU type for finishing and NSU type for light cutting.

The NFB and NLB type chipbreakers improve chip control in finishing of low carbon and general steel.
