CNMG120412-NRS WSM10S – Indexable turning insert, Tiger·tec Silver, Walter Tools

The CNMG120412-NRS WSM10S is a negative‑rake, rhombic 80° indexable insert designed for turning stainless steels and heat‑resistant superalloys in demanding production environments.

• Tiger·tec Silver coating for high heat resistance
• Optimised NRS chipformer for secure chip control
• Rhombic 80° geometry with 1.2 mm corner radius
• Suitable for stainless steels and superalloys

Enhanced reliability when machining tough alloys

The WSM10S grade, built on Tiger·tec Silver coating technology, is engineered to improve process stability when cutting tough-to-machine materials. The combination of a heat-resistant coating and a coated carbide substrate supports a stable cutting edge under elevated temperatures, which reduces the risk of edge build-up and unplanned tool changes. The rhombic 80° geometry with a corner radius 1.2 mm and a 0° negative relief improves edge strength and load distribution, providing predictable performance in interrupted or heavy cuts while maintaining surface quality.

Productivity gains through controlled chip formation

The integrated NRS chipformer promotes consistent chip breaking and evacuation, which lowers the likelihood of chip entanglement and secondary finishing operations. Because chip control is optimised, cycle times can be shortened and tool life extended, offering a direct productivity advantage on parts made from stainless steels and superalloys. The insert’s profile and edge preparation support repeatable surface finishes and reduce rework, contributing to cost-efficient series production and fewer process interruptions.

Practical advantages for workshop integration

Designed in a standard CNMG style, the insert fits conventional negative‑rake toolholders and is straightforward to index, keeping changeover times minimal. The WSM10S grade tolerates the thermal and mechanical stresses typical of ISO group M and S materials, so the same insert family can often be standardised across multiple jobs. Clear specification of the insert geometry and chipformer means insertion into tool management systems is simple, helping to streamline tooling logistics and inventory control in the shop.

What this means for everyday machining

Adopting this insert supports a rational approach to problem solving: fewer edge failures, more stable cycles and more consistent part quality. The engineered balance between coating, substrate and chipformer makes the insert particularly useful where heat generation and workpiece toughness present recurring challenges. For planned production runs on stainless steels or heat‑resistant alloys, this insert helps maintain throughput while protecting component surface integrity and dimensional consistency.
