TaeguTec CCMT120404PC TT8115 | High-Speed Steel Turning Insert SOMT 13 GK Chipbreaker: The GK geometry

GK Chipbreaker: The GK geometry is a robust design for cast iron machining

and heat-resistant alloys under high-load conditions

TT9225 (CVD) is optimized for higher speeds and thermal stability in continuous turning

The left-hand (L) orientation combined with a 75° approach angle provides unparalleled radial edge strength for handling scale removal and interrupted cuts up to an extended 3xD to 4xD overhang ratio

45° Optimized Lead Angle: Drastically reduces radial forces by redirecting cutting resistance axially back into the machine spindle for high-stability roughing
