Features & benefits

Medium wide positive T-land improves the cutting edge strength allowing light to medium feeds and enabling versatile machining with lower cutting forces
3-D chip-breaker ensures chip-breaking control at wide range of feeds and depths of cut
Medium width chip-groove reduces the cutting resistance and vibration, hence increase machining performance
Deep chip-groove reduces cutting forces and vibration
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
Highly positive geometry reduces the cutting forces and machining load significantly enabling smooth turning with minimal vibration
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.
