Applications

This turning insert is specifically engineered for robust roughing applications in stainless steel. Thanks to its negative basic shape and stable cutting edge, it excels in machining tough stainless steels across both batch and individual production environments. Its optimization for continuous and light interrupted cuts makes it a highly versatile choice for facing and longitudinal turning of challenging workpiece contours.

The CNMM insert is frequently used in mechanical engineering, plant construction, and fixture manufacturing, where reliable cutting performance and predictable process security are essential.

Special features

The PVD coating of the RT255M grade provides excellent protection against premature wear and built-up edge formation, which is a decisive advantage when turning stainless steel. The underlying M20-M30 carbide exhibits high toughness, allowing it to withstand mechanical and thermal fluctuations during the cut.

Paired with the specialized SXR roughing geometry, the insert achieves effective chip control, reducing the risk of chip jamming and maintaining consistent surface quality even under demanding roughing parameters.
