Technical Advantages

15° Large Side Relief: Engineered with a significant 15° clearance angle to eliminate friction and interference with the workpiece side wall, even in the most challenging deep grooving applications.
Double-Headed Efficiency: The symmetrical double-edged structure maximizes value—simply rotate the insert to utilize the second fresh cutting edge, doubling the service life per insert.
Optimized Chipbreaker: Specialized front rake geometry with guide ribs forces chips into tight curls, effectively preventing chip wrapping and bird-nesting in narrow channels.
Honed Edge Stability: Precision edge passivation improves the toughness of the cutting tip, significantly reducing the risk of micro-chipping during intermittent or high-load external cuts.
Rigid Clamping: Designed for standard press-plate tool holders, providing high dimensional repeatability and exceptional stability for high-speed CNC parting-off.
