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
- Wide chip-groove enhances the chip-control when machining tough materials improving chip evacuation
- Shallow chip-groove ensures chip breaking at wide range of cutting feeds
- 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.
