Features & benefits

Raised chip-breaker back wall height forces the chip to curl more tightly which improves the ability to chip break allowing machining of tough work-materials with lower feeds
Positive geometry reduces the cutting forces, temperature and power requirement, exerting less stress on the workpiece, tool and machine spindle which helps to control chatter
WC-Co based substrate submicron grained, provides high hardness and abrasive wear resistance, resistance against comb cracks
PVD coating, enhances thermal cracking resistance and performance in operations involving cutting temperature fluctuations
A multi-layered PVD coating optimized for increased productivity and durability. Thick TiN coating with low compressive stress for crater wear resistance and hard AlTiN layer for flank wear resistance.
Unique Titanium-Boron-Nitride (TiBN) top layer for build-up edge reduction and improved performance.
New coating generation provides increased durability and performance. It is the most versatile grade for general turning and heavy roughing, even in unfavourable conditions.
Rounded edges without T-land enables smooth machining with light feed and shallow depths of cut delivering sufficient edge strength while limiting the risk of work-hardening
3-D chip-breaker ensures chip-breaking control at wide range of feeds and depths of cut
Wide chip-groove enhances the chip-control when machining tough materials improving chip evacuation
Deep chip-groove reduces cutting forces and vibration
