WCMT040202-RM4 WSM30S turning/boring insert — Tiger·tec Silver, RM4 chipbreaker (Walter Tools)

WCMT040202-RM4 WSM30S is a trigon 80° indexable insert designed for demanding turning and boring operations in heat-resistant and stainless materials

• Tiger·tec Silver for heat-resistant machining
• Optimised RM4 chipbreaker for stable chips
• Trigon 80° form for a robust cutting edge
• For stainless steels and superalloys

High-temperature cutting performance that extends tool life

The WCMT040202-RM4 WSM30S insert combines a WSM30S coated-carbide grade with Tiger·tec Silver technology to deliver consistent wear resistance under elevated temperatures. The coated-carbide substrate and multi-layer coating are engineered to reduce adhesion and thermal impact when machining stainless steels and superalloys, which typically generate heat and promote workpiece build-up. This results in a measurable improvement in cutting-edge life and process stability, enabling longer uninterrupted cycles and fewer tool changes, which benefits productivity and cost efficiency in production environments.

Predictable chip control and cutting stability for safer machining

A defined RM4 chipbreaker together with the Trigon 80° geometry creates controlled chip formation and evacuation during roughing and finishing passes. The combination of a 0.2 mm corner radius and a 7° relief angle provides a balance between edge strength and shear efficiency: the small radius supports a robust cutting edge for interrupted cuts, while the relief angle reduces rubbing and heat build-up. Improved chip control minimises the risk of built-up edge and reduces rework, making component quality more consistent and machine downtimes less frequent.

Application guidance and compatibility for process planning

This insert is intended for machining applications in material groups S (superalloys, titanium) and M (stainless steels), where thermal resistance and edge stability are essential. The coated carbide grade performs well in heavy-duty turning and boring where material adhesion and heat generation challenge conventional grades. For integration into existing tool holders, the trigon form and size designation ensure straightforward replacement and predictable cutting data. For process set-up, select speeds and feeds that favour stable cutting temperatures and exploit the coating’s thermal advantages to extend tool life.

FAQ

Which materials is this insert suitable for?
The WCMT040202-RM4 WSM30S insert is designed for stainless steels and heat-resistant superalloys (material groups M and S) and is optimised for applications that demand thermal and edge stability.

What benefits does the Tiger·tec Silver coating provide?
Tiger·tec Silver on the WSM30S grade improves thermal resistance and reduces adhesion, helping to maintain a sharp cutting edge and extend tool life during high-temperature turning and boring operations.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker promotes consistent chip segmentation and evacuation, improving surface finish and reducing the likelihood of built-up edge when machining difficult materials.

Is the insert compatible with standard trigon tool holders?
Yes, the Trigon 80° form and the WCMT040202-RM4 designation match common trigon tool holders; verify holder compatibility and cutting parameters before full production runs.
