Applications

This turning insert is a well-conceived solution for turning operations where flexibility is required. It is primarily used for medium machining tasks involving steel and stainless steel workpieces. Thanks to its tolerance for light interrupted cuts, it opens up variable application possibilities in modern manufacturing without the constant need for tool changes between different materials.

Special features

The positive DCMT basic shape generates relatively low cutting forces, helping to protect both the spindle and the workpiece. A key advantage is the universal RT300 grade: the specifically formulated PVD coating effectively counteracts abrasive wear and contributes to consistent cutting performance. The inserts are supplied in a convenient packaging unit of 10 pieces.
