The N80K Blade – BN8110 is a heavy-duty H.S.S. deburring blade designed for key seats, keyways, slots, and narrow machined features.
Its specialized cutting geometry allows controlled removal of burrs from recessed edges and confined areas where standard deburring blades may have limited access. With a working range of 2.4-11 mm, the N80K is particularly suitable for finishing key seats and similar internal features created during machining.
Manufactured from durable High-Speed Steel (H.S.S.) with a hardness of 62-64 Rc, the N80K provides reliable cutting performance and good wear resistance for repetitive machining, maintenance, toolmaking, and production applications.
The 55° cutting angle supports precise manual deburring while maintaining good control along narrow internal edges. The N80K is designed for use with compatible Noga double-edge cutting tools and holders.
