TNMG160408-MU5 WSM20S — indexable turning insert for stainless steel and superalloys (Walter Tools)

The TNMG160408-MU5 WSM20S is a triangular indexable turning insert designed for heavy-duty machining of stainless steel and heat-resistant superalloys.

• Tiger·tec Silver coating for stable cutting
• Optimised MU5 chipbreaker for secure chip control
• Suited for stainless steel and nickel‑based alloys
• Triangle 60° insert with 0.8 mm corner radius

High-performance cutting for stainless steel and superalloys

The WSM20S grade, based on Tiger·tec Silver technology, is formulated to cope with the thermal and mechanical stresses typical of stainless steel and heat‑resistant superalloys. The coated carbide construction supports a stable cutting edge under high temperatures and reduces the risk of built-up edge, which translates into fewer interruptions and more predictable machining cycles. This stability benefits cycle times and repeatability, making the insert suitable for production environments where consistent output is critical.

Robust geometry and chip management for uninterrupted productivity

The combination of the MU5 chipbreaker and a triangle 60° form provides controlled chip formation and evacuation during medium to heavy turning operations. The 0° negative free angle and a 0.8 mm corner radius contribute to a strong cutting edge that resists chipping during interrupted cuts and plunge operations. With a plate size of 16 and a plate thickness of 04, the insert offers mechanical strength and clamping security, helping to maintain cutting parameters and avoid unexpected tool changes.

Durable coating and consistent edge quality to reduce rework

The insert’s Tiger·tec Silver coating improves wear resistance and thermal stability, delivering longer edge life and steadier surface finishes. A tolerance class of M ensures dimensional consistency between inserts, aiding tool setup and repeatable results across batches. These characteristics reduce the frequency of rework and inspection, supporting lean production goals and lowering per‑part machining costs while preserving component quality.
