WNMG080412-NRS WSM30S indexable turning insert – Trigon 80°, Tiger·tec Silver, Walter Tools

WNMG080412-NRS WSM30S is an indexable turning insert tailored for heavy and demanding turning operations, optimised for stainless steel and heat‑resistant superalloys with a negative 0° relief and a 1.2 mm corner radius

• Tiger·tec Silver coated for high thermal resistance
• Optimised NRS chipbreaker for secure chip control
• Trigon 80° geometry with negative 0° relief
• 1.2 mm corner radius for durable cutting edge

High thermal stability and wear resistance for continuous production

The insert features Tiger·tec Silver coating on a coated carbide substrate, engineered to withstand elevated cutting temperatures and abrasive conditions. This results in improved process stability, reduced flank wear and fewer changeovers. The combination of coating technology and a robust substrate supports stable cutting edges when machining challenging materials, ensuring predictable tool life and less unplanned downtime. As a consequence, machining cycles in series production run more smoothly and with consistent quality.

Geometry and chip control that reduce rework and tool loading

The Trigon 80° shape with a negative 0° relief provides a rigid cutting geometry for interrupted cuts and heavy radial engagement. Matched with the NRS chipbreaker, the insert confines and breaks chips reliably, lowering the risk of built‑up edge and tool damage. Improved chip formation translates into fewer surface defects and reduced need for manual cleaning of workpieces, which supports higher first‑pass yields and more efficient downstream operations.

Application range: robust for stainless steel and high‑temperature alloys

Formulated for the ISO groups M and S, this grade is suitable for machining stainless steel as well as heat‑resistant superalloys and titanium. The WSM30S grade balances thermal resistance with edge stability, making it appropriate for both steady‑state turning and tougher intermittent cuts. By choosing this insert for demanding materials, process engineers gain a practical tool for maintaining cycle times while protecting the cutting edge against thermal degradation.

Compatibility, tolerance and economic benefits for workshop workflows

With a size designation of 08, thickness code 04 and tolerance class M, the insert integrates with standard trigon toolholders and clamping systems. The 1.2 mm corner radius offers a compromise between edge strength and surface finish, suitable for many general‑purpose to semi‑finishing tasks. The predictable wear behaviour and the Tiger·tec Silver technology help to lower total cost of ownership by extending usable life per edge and reducing frequency of tool changeovers. For toolrooms seeking repeatable performance, this insert supports higher machine utilisation and steadier output quality.

FAQ

What materials can this insert machine effectively?
The WNMG080412-NRS WSM30S from Walter Tools is designed for stainless steel and for heat‑resistant superalloys/titanium (ISO groups M and S), making it suitable for demanding turning tasks where thermal resistance is required.

How does the 1.2 mm corner radius affect performance?
A 1.2 mm corner radius increases edge strength and improves resistance to fracture and chipping on the WNMG080412-NRS WSM30S, which helps maintain consistent surface quality in heavier cut conditions.

Why is the NRS chipbreaker important for production?
The NRS chipbreaker on this Walter Tools insert shapes and controls chips to prevent long swarf, reduce tool loading and lower the chance of built‑up edge, contributing to safer and more efficient machining.

Is the trigon 80° geometry suitable for interrupted cuts?
Yes. The Trigon 80° form with negative 0° relief provides rigidity and shock resistance, which is advantageous for interrupted cutting and operations with variable engagement.

What tolerance and mounting details are relevant for tool selection?
The insert is supplied in tolerance class M with size designation 08 and thickness code 04; these details help ensure proper seating in compatible trigon toolholders for repeatable clamping and concentricity.
