Applications
This milling insert is tailored for the professional machining of steel, stainless steel, and cast iron. The round design of the RTHX series permits its use in demanding copy milling and profile milling tasks. The insert's shape ensures a smooth distribution of cutting forces, offering highly flexible application options in modern machining technology.
Special features
A key design feature of this indexable insert is its highly stable cutting edge, which is achieved through a 0° rake angle combined with a defined clearance angle. This robust edge design minimizes the risk of chipping under fluctuating cutting conditions. Complemented by the wear-resistant PVD-coated carbide of grade RT350, the tool supports reliable tool life and solid process security during continuous operation.
