Applications
This wiper turning insert is designed for mass production and continuous turning operations on steel components. The specialized geometry makes it a strong choice for users in the automotive industry, mechanical engineering, and supplier networks who need to achieve a pristine surface quality directly on the CNC machine, often saving additional polishing or grinding steps.
Special features
The combination of a tough carbide substrate and the modern CVD coating of the RT315G grade provides a strong foundation for high wear resistance in continuous cuts. The negative WNMG design delivers excellent process stability, while the integrated wiper technology reliably enhances efficiency through an extended contact path and optimized surfaces.
