CNMG160612-NRS WMP20S – Turning indexable insert for stainless steel, Tiger·tec Silver by Walter Tools

A CNMG160612-NRS WMP20S turning insert engineered for dependable performance in medium to robust stainless steel turning operations

• Tiger·tec Silver coated carbide grade
• Optimised for stainless steel machining
• Rhombic 80° insert with 1.2 mm radius
• Negative 0° clearance geometry

High-performance turning for stainless steels

The CNMG160612-NRS WMP20S is built around a coated carbide grade from the Tiger·tec Silver family, designed to tackle the peculiarities of stainless steel: toughness, work-hardening and thermal sensitivity. The coated substrate supports a stable cutting edge under increased heat generation, which reduces the risk of built-up edge and extends tool life. By combining a robust grade with a dedicated chipformer, the insert delivers consistent material removal rates and contributes to predictable cycle times in serial production.

Improved chip control and edge security for reliable productivity

A focus on chip control underpins this insert’s design: the NRS chipbreaker shapes chips to avoid entanglement and to support uninterrupted turning. The 1.2 mm corner radius and rhombic 80° form give a secure edge for moderate to heavier cuts, improving surface finish without sacrificing edge strength. The negative 0° clearance geometry provides a firmer orientation in the tool holder, beneficial when facing intermittent cuts or tougher stainless grades. These characteristics together reduce rework and machine idle time, making the tooling choice an efficiency decision.

Practical integration and application advantages

With the standard CNMG form factor and a nominal size indicator 16, the insert fits common indexable turning toolholders, enabling straightforward integration into existing tool sets. The WMP20S grade is oriented towards stainless steels and supports medium to robust cutting regimes, which simplifies grade selection across similar job types. For process planners, the result is a versatile insert that balances edge life and cutting performance, helping to lower tooling-related downtime while maintaining repeatable part quality.
