Applications
This tool is ideally suited for the medium machining of various cast iron components. The insert not only handles continuous cuts with ease but also demonstrates high resilience under light to heavily interrupted cutting conditions. This opens up flexible application possibilities in industrial production, where fluctuating process environments or interrupted workpiece contours are part of the daily routine.
Special features
The wear-resistant CVD coating of the RT150K grade creates favorable conditions for consistent workflows in metal cutting. Together with the robust corner geometry, the WNMG insert supports reliable chip formation and efficient material removal rates. Delivery comes in a practical packaging unit of 10 pieces, ensuring a reliable supply at the lathe for professional users.
