High-Performance Roughing in Special Materials
The DNMG-SNR RT130S turning insert is a well-thought-out solution for the demanding machining of heat-resistant super alloys. With its stable insert shape and the SNR roughing geometry, it masters continuous as well as light and heavy interrupted cuts. The special PVD coating of the RT130S grade supports efficient workflows when machining difficult-to-cut materials and opens up flexible application possibilities in industrial manufacturing.
