Applications
This robust turning insert is tailored to the versatile requirements of machining cast iron. The geometry and coating prove their worth particularly in medium machining, where they support reliable chip evacuation during both uniform material removal and light or heavy interrupted cuts.
The DNMG...-KC RT150K opens up flexible application possibilities in mechanical engineering and series production. With a choice of two corner radii (0.8 mm and 1.2 mm), the tool can be optimally adapted to the specific contour machining requirements.
Special features
The core of this rhombic turning insert is the RT150K grade, a CVD-coated K10-K20 carbide. This coating technology ensures high thermal stability and strong wear protection, which has a positive effect on the overall tool life. The well-thought-out design for interrupted cuts reduces the risk of cutting edge chipping and enables highly efficient workflows.
