SNMG150612-RM5 WSM20S — Square 90° turning insert, RM5 chipbreaker, Walter Tools

The SNMG150612-RM5 WSM20S is a square 90° indexable insert optimised for turning rostfreier Stahl and hot, difficult‑to‑cut alloys in demanding production environments

• Tiger·tec Silver coating for extended edge life
• Suitable for rostfreier Stahl and superalloys
• RM5 chipbreaker for controlled chip formation
• 1.2 mm corner radius for robust cutting performance

Higher process reliability with advanced coating and substrate

The combination of the Tiger·tec Silver coating and a wear‑resistant cemented‑carbide substrate delivers improved edge life and consistent performance in serial production. Designed for materials classified as M (rostfreie Stähle) and S (heat‑resistant superalloys and titanium) under ISO 513, the insert’s microstructure promotes secure chip formation and reduced tendency for built‑up edge when machining tough, temperature‑sensitive workpieces. For production planning, this translates into fewer interruptions, more predictable tool changes and a stable surface finish across batches.

Geometry that promotes stability and efficient chip control

The square 90° shape with a 1.2 mm corner radius and RM5 chipbreaker provides a balance between edge strength and cutting versatility. A negative 0° rake (0° negative) increases cutting‑edge robustness for interrupted cuts and heavy depths of cut, while the chipbreaker geometry channels chips away from the cutting zone to reduce heat load and tool stress. These design choices lead to lower scrap rates and steadier cycle times, making the insert suitable for shoulders, medium‑deep longitudinal turning and demanding finishing operations where edge security matters.

Practical integration and predictable tool management

The insert is compatible with standard indexable turning systems that accept SNMG‑style geometry and can be used across a range of holders to suit roughing and finishing operations. Classification under the WSM20S grade within the Tiger·tec Silver series simplifies grade selection for mixed‑material production: one grade supports both rostfreier Stahl and high‑temperature alloys, reducing inventory complexity. For machining strategy, expect consistent tool behaviour and an easier path to process standardisation; consult technical data sheets or our application engineers to match feeds, speeds and coolant strategy to specific alloys.

FAQ

What materials is this insert best for? The SNMG150612-RM5 WSM20S grade is engineered for rostfreier Stahl and heat‑resistant superalloys/titanium (ISO groups M and S), providing secure chip formation and edge stability.

How does the RM5 chipbreaker help in production? The RM5 chipbreaker on this Walter Tools insert directs chips reliably away from the cut and reduces heat concentration, improving process stability and surface quality.

Is the insert suitable for interrupted cuts and roughing? Yes, the square 90° geometry combined with a 1.2 mm corner radius and negative 0° rake delivers robust performance for interrupted cuts and moderate roughing operations.

Can one grade be used across different steels and superalloys? The WSM20S grade within the Tiger·tec Silver series is intended to cover both rostfreier Stahl and certain high‑temperature alloys, helping to simplify tooling assortments.

How to select the correct holder and clamping for this insert? Use a turning holder compatible with SNMG inserts and follow the holder manufacturer’s clamping specifications; correct clamping ensures repeatable seat location and optimal cutting conditions.
