TPMT090204-MM4 WSM20S indexable turning insert, Tiger·tec Silver — Walter Tools

A TPMT090204-MM4 WSM20S indexable turning insert designed for heavy-duty machining of stainless steels and heat‑resistant superalloys, featuring a triangular 60° shape and a 0.4 mm nose radius for versatile turning tasks

• Tiger·tec Silver coated for heat resistance
• Suitable for stainless steels and superalloys
• Triangular 60° form with 0.4 mm nose radius

High performance for demanding materials

The coated carbide grade WSM20S from the Tiger·tec Silver series is optimised for secure chip formation and edge stability when turning tough materials. This grade supports machining of stainless steels and heat‑resistant superalloys (ISO groups M and S), where high cutting temperatures and workpiece toughness can otherwise shorten tool life. The combination of a dedicated chipbreaker MM4 and the grade’s coating technology reduces the tendency for built‑up edge and contributes to consistent surface finish and predictable tool change intervals.

Geometry that improves process reliability

A triangular 60° insert form delivers three usable cutting edges per body, increasing economy in production. The small 0.4 mm nose radius helps to control cutting forces and achieve the required edge definition on external profiles and light finishing passes. The 11° clearance angle and the insert thickness coded as 02 ensure compatibility with common compact toolholders while maintaining rigidity; this geometry supports stable turning even under interrupted cuts and higher feed rates.

Coating advantages and thermal resistance

The Tiger·tec Silver coating provides a thermal barrier and enhanced hardness at elevated temperatures, which is crucial when machining materials that do not dissipate heat readily. Coated carbide construction enhances resistance to abrasive wear and prolongs the life of the cutting edge, enabling longer tool cycles and fewer tool changes. The WSM20S coating strategy is tailored to maintain a stable cutting edge under the thermal and mechanical loads typical for superalloys and stainless steels.

Practical use and economic benefit in production

Integrating this insert into a turning line can lead to measurable gains in process security and productivity: predictable wear behaviour reduces unplanned stoppages, and the multi‑edge triangular format lowers tooling cost per edge. The MM4 chipbreaker assists in controlled chip formation, which improves chip evacuation and can reduce downtime for manual chip handling. For manufacturers seeking a balance between thermal robustness and repeatable performance, this insert provides a productive solution that is straightforward to implement with standard rigid toolholders.

FAQ

What materials is this insert designed for?
The TPMT090204-MM4 WSM20S is intended for stainless steels (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), offering thermal resistance and stable chip formation for these materials.

How does the MM4 chipbreaker affect performance?
The MM4 chipbreaker promotes controlled chip formation and evacuation, which enhances surface finish and reduces the risk of entangling chips during turning with the WSM20S grade.

What are the key geometry features and their benefits?
The triangular 60° shape provides three usable cutting edges per insert and a compact footprint; the 0.4 mm nose radius aids in producing defined profiles while moderating cutting forces.

Is this insert compatible with general-purpose toolholders?
Yes, the insert format TPMT090204-MM4 is compatible with standard compact turning toolholders designed for triangular 60° inserts; ensure the seat and clamp match the insert code.

How does the Tiger·tec Silver series improve tool life?
Tiger·tec Silver coating increases high‑temperature hardness and wear resistance, extending edge life in demanding applications such as machining superalloys and stainless steels.
