Applications

Due to its specific characteristics, the SNMU 130520-UM indexable insert is excellently suited for high-feed applications in modern metal processing. It supports efficient workflows when machining components made of steel and stainless steel. Additionally, the RT305H variant enables the process-reliable machining of superalloys, which provides the tool with flexible application possibilities in general machining and jig manufacturing.

Special features

A key feature of this milling insert is its eight usable cutting edges, which allow for very high cost-efficiency in productive use. The optimized 3D contour of the cutting edge effectively contributes to minimizing the occurring cutting forces and promoting a smooth cut. This not only protects the tool system and spindle but also leads to significantly increased process reliability during intensive roughing operations.
