Applications
This modern insert is specifically aimed at contouring, profiling, and longitudinal turning of steel components. Due to the acute 35° shape, it opens up flexible application possibilities for complex workpiece contours and intricate boring operations. When soft or tough steel types are being machined, the tool acts as a dedicated problem-solver, preventing troublesome chip tangling during finishing procedures.
Special features
The next-generation CVD coating gives the RT315G grade dependable wear resistance in continuous cutting scenarios. The special PF chipbreaker not only optimizes chip formation but also has a noticeably positive impact on tool life and the resulting surface finish. This supports efficient machining processes and reduces unnecessary machine downtime.
