The DNMG-GF is a high-precision 55° rhombic negative-rake indexable turning insert specifically engineered for finishing operations. Featuring a standard 0° clearance angle and double-sided cutting edge structure, this insert delivers superior rigidity and impact resistance compared to positive-rake inserts, effectively suppressing cutting vibration during precision machining.
The professionally optimized GF finishing chipbreaker enables delicate and stable chip breaking with smooth chip evacuation under small depth of cut and low feed rates. This design completely eliminates chip entanglement, workpiece scratching, and burrs.
Versatile for precision turning of carbon steel, alloy steel, and stainless steel, this insert is ideal for high-precision mass production applications.
- Application: Finishing of steel
