Applications
The DNMG-SM RT110S is primarily used in turning applications that involve continuous cuts on heat-resistant super alloys and demanding special materials. Thanks to its geometry designed for medium chip removal, it is perfectly suited for users who require process-reliable chip control at constant cutting depths. Typical tasks such as longitudinal and contour turning of rotationally symmetrical components can be executed with great efficiency.
Special features
The PVD-TialSin coated S10 carbide serves as the foundation for outstanding thermal resistance and reduced edge wear when subjected to high heat. Combined with the SM chipbreaker, this insert achieves reliable tool life and consistent cutting behavior. This material combination guarantees stable performance during continuous cuts, allowing professionals to benefit from reproducible results and minimized tool changeovers.
