BC8220 utilises a new specially developed, super multi-layer ceramic PVD coating. The high level of both chipping and wear resistance is achieved by a much improved adhesion between the substrate
and coating. Together with the easy identification of use due to the gold coloured TiN top coating layer,
BC8220 achieves high performance and reliability over a wide range of hardened steel machining
The new CBN substrate contains a new ultra-fine grain, heat resistant binder.
This suppresses both chipping and crater wear that promotes longer tool life.
The progress of crater wear is greatly reduced due to the use of a heat resistant binder.
This suppresses chipping, crater wear and fracturing.
The ultra micro-particles binder prevents linear crack development to avoid sudden fracturing.
BC8220 is ideal for both high speed and interrupted cutting and expands the application area of
New VA honing type with improved fracture resistance for high speeds and feed.
CNGM and DNGM types are now available with new inserts that combine a BF chip breaker with a WS
wiper Insert. (BF-oNGMooooooTAWS2)
It is effective for chip control and improvement of finished surface roughness without worrying about the
hand of the tool even in continuous external turning or internal turning and facing.
BC8220 achieves excellent wear resistance and finished surface when compared to conventional products.
BC8220 has excellent chipping and fracture resistance.
