High feed milling insert SNMU 130520-UM for efficient metalworking

The SNMU 130520-UM indexable insert is a proven component explicitly engineered for high material removal rates in professional machining. Thanks to its robust, double-sided design, this milling insert creates excellent conditions for demanding roughing and medium machining tasks. Users can select between the versatile RT250X grade, which features a PVD multilayer coating, and the high-performance RT305H grade to perfectly tailor the tool to their specific requirements. This ensures consistent and convincing results in industrial environments.

Applications

This milling tool is deliberately targeted at challenging high-feed applications in general engineering and batch production. The RT250X variant proves to be a reliable all-round solution, supporting efficient workflows when handling steel and stainless steel components. Meanwhile, the RT305H version expands the operational range by accommodating difficult-to-cut superalloys. As a result, this system represents an excellent choice for a variety of evolving manufacturing tasks.

Special features

The SNMU 130520-UM stands out due to its intelligent layout incorporating eight usable cutting edges, facilitating exceptional cost-efficiency during production. The carefully designed cutting edge geometry promotes smoother running behavior, helping to mitigate mechanical stress on both the milling cutter and machine spindle. This significantly contributes to maintaining robust process stability, even when undertaking heavy roughing operations with large chip volumes.
