TCMT110204-MM4 WSM20S — Triangle 60° Turning Indexable Insert, Tiger·tec Silver — Walter Tools

TCMT110204-MM4 WSM20S is a triangular turning indexable insert optimised for machining rostfreier Stahl and heat‑resistant alloys in demanding turning and boring operations.

• Tiger·tec Silver coating for high process security
• WSM20S grade for rostfreier Stahl and superalloys
• Triangle 60° form for three usable cutting edges
• Chipbreaker MM4 for controlled chip formation

Consistent performance in rostfreier Stahl and superalloys

The WSM20S grade, part of the Tiger·tec Silver series, is a coated carbide designed for challenging materials such as rostfreier Stahl (ISO group M) and heat‑resistant superalloys (ISO group S). The coating enhances heat resistance and adhesion behaviour at the cutting edge, which results in stable chip formation and longer tool life. For production environments where material toughness and thermal load are high, the combination of coating and grade translates into fewer tool changes and improved uptime.

Predictable chip control and surface quality

The MM4 chipbreaker is engineered to produce consistent chip formation under the high heat and strain typical of machining stainless steels and nickel‑base alloys. The triangular 60° plate form provides three indexable cutting edges per insert, enabling rapid index changes and efficient tool use. With a corner radius of 0.4 mm, operators can expect a balance between strength at the edge and the ability to achieve a fine surface finish; this geometry supports both roughing and mixed finishing passes while maintaining dimensional stability.

Geometry and tolerance for repeatable turning

Key geometric features—clearance angle 7°, triangle 60° profile and the plate thickness designation 02—combine to give repeatable clamping and consistent contact conditions at the tool‑workpiece interface. The insert is produced to tolerance class M, ensuring interchangeability and predictable results across batches. These characteristics reduce setup variance and support process standardisation, which is essential for series production and quality control in metalworking.

Application focus and process benefits

Designed for heavy‑duty machining of rostfreier Stahl and, depending on insert geometry, titanium and other high‑temperature alloys, this turning insert supports high process security and a reliable cutting edge under thermally aggressive conditions. The practical benefits are clear: improved productivity through longer tool life, reduced scrap rates due to consistent chip control, and straightforward inventory management thanks to a well‑defined ISO designation and proven Walter Tools quality.

FAQ

What materials is this insert suitable for?
The TCMT110204-MM4 WSM20S turning insert (Walter Tools) is designed for rostfreier Stahl (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), offering enhanced heat resistance and stable cutting edges for these materials.

How does the Tiger·tec Silver series benefit machining?
The Tiger·tec Silver coating improves thermal resistance and reduces adhesion at the cutting edge, which helps the insert maintain stable chip formation and extended edge life during aggressive machining.

What does MM4 chipbreaker deliver in practice?
The MM4 chipbreaker produces predictable, controllable chips under high thermal load, lowering the risk of built‑up edge formation and promoting consistent surface finish during both roughing and mixed finishing.

Is the 0.4 mm corner radius suitable for finishing?
A 0.4 mm corner radius strikes a balance between edge robustness and surface finish capability, allowing for controlled cutting forces while offering the possibility of fine surface quality in follow‑up passes.

Can this insert be used for boring and turning applications?
Yes, the insert is specified as a turning/indexable insert suitable for boring and external turning operations where the plate form and grade match the application demands.
