CNMG120412-MM5 WMP30G – Rhombic 80° coated turning insert, Tiger·tec Gold by Walter Tools

The CNMG120412-MM5 WMP30G is a coated turning insert engineered for secure machining of stainless steel under medium to robust cutting conditions.

• Tiger·tec Gold coating technology
• Designed for stainless steel machining
• MM5 chipbreaker for stable chips
• 1.2 mm corner radius for robust edges

Longer tool life and consistent performance in stainless steels

The WMP30G grade, developed within the Tiger·tec Gold family, is optimised for the particular challenges of machining stainless steel: high work hardening, adhesive tendencies and elevated cutting temperatures. As a coated carbide insert, it provides improved wear resistance compared with uncoated grades and supports a predictable tool life. For process engineers this means fewer insert changes, reduced downtime and a more consistent surface finish on finished components.

Secure cutting edge and reliable chip control for production environments

The combination of a Rhombus 80° geometry with a 0° (negative) relief angle and a 1.2 mm corner radius provides a strong cutting edge that resists chipping during interrupted cuts. The integrated MM5 chipbreaker promotes controlled chip formation when turning tough, ductile alloys, reducing entanglement and the risk of surface damage. These technical choices translate into stable machining windows and easier handling at elevated feeds and variable depths of cut.

Easy integration and predictable tool management on the shop floor

Designed to the CNMG designation, the insert fits common CNMG toolholders and clamping systems, simplifying tool inventory and changeover procedures. The CNMG120412-MM5 format and the coated grade support repeatable indexability; operators can expect consistent performance across insert seats. Combined with the grade’s tolerance class M and Walter Tools’ manufacturing standards, the result is a reliable component for series production and demanding turning tasks.
