Applications
The turning insert is optimally aligned for machining stainless steels. It is primarily used for roughing operations and medium turning, showing its strengths in both continuous and light interrupted cuts. Thanks to the R and L versions, the tool can be ideally matched to the respective lathe toolholder.
Special features
The PVD grade M20-M30 with its modern coating ensures consistent results during the turning of stainless steel. The choice between 0.4 mm and 0.8 mm corner radii additionally allows for a precise adaptation to the required contour and surface finish.
