WNMG100612-MM5 WSM20S — Indexable turning insert, Trigon 80°, WSM20S by Walter Tools

WNMG100612-MM5 WSM20S is a trigon indexable turning insert designed for heavy-duty and difficult-to-machine materials, especially rostfreier Stahl and heat-resistant superalloys

• Tiger·tec Silver coated carbide grade WSM20S
• Trigon 80° form for secure engagement
• 0° negative rake for maximum edge stability
• MM5 chipbreaker for controlled chip formation

Consistent productivity through stable edge and coating technology

The Tiger·tec Silver coating and the WSM20S grade combine to provide enhanced heat resistance and improved wear behaviour when turning demanding alloys. This results in fewer tool changes and a steadier process flow. The coated carbide substrate supports a stable cutting edge, which reduces the risk of built-up edge when machining rostfreier Stahl and superalloys; the net effect is longer productive cutting times and more predictable component quality. For production environments where cycle time and repeatability matter, this insert contributes directly to higher throughput and lower process variability.

Secure cutting geometry for reliable engagement and surface finish

The trigon 80° plate form and the 0° (negative) rake angle prioritise edge strength and cutting security. The corner radius 1.2 mm absorbs cutting forces and reduces chatter, while the robust geometry supports consistent surface integrity on difficult materials. The MM5 chipbreaker is engineered for controlled chip segmentation, improving swarf evacuation and reducing the likelihood of chip re-cutting. In practical terms, this means fewer rejects and less rework when producing turned components from tough alloys or rostfreier Stahl.

Application benefits: what this insert delivers on the shop floor

Specifically developed for applications in groups S and M according to ISO 513, the insert enables confident machining of heat-resistant superalloys and rostfreier Stahl by combining thermal stability with reliable chip control. The insert's execution and tolerance class emphasise repeatable seating and dimensional accuracy in common toolholders. For manufacturers aiming to balance high material removal rates with consistent surface quality, the combination of Tiger·tec Silver, the MM5 chipbreaker and the trigon geometry supports both aggressive and finishing passes, reducing cycle times without compromising component integrity.

FAQ

What materials is this insert suitable for?
The WNMG100612-MM5 WSM20S insert is specified for machining groups S (superalloys, titanium) and M (rostfreier Stahl) and is optimised for these challenging materials.

Which chip control feature ensures safe swarf management?
The MM5 chipbreaker integrated in this insert provides controlled chip segmentation, improving evacuation and preventing entanglement in turning operations.

How does the trigon 80° form affect cutting behaviour?
The trigon 80° shape increases engagement security and supports robust cutting edges; this geometry is beneficial for heavy cuts and maintaining surface finish on demanding alloys.

Is the coating suitable for high-temperature cutting?
Yes—the Tiger·tec Silver coating on the WSM20S grade enhances heat resistance and wear performance, supporting longer tool life in high thermal loads.

Which tolerance and execution are provided for repeatable mounting?
The insert comes in tolerance class M and execution G, which ensure consistent seating and repeatable performance in standard toolholders.
