TCMT16T304-RM4 WSM20S — triangle turning/drilling indexable insert for stainless steels & superalloys (Tiger‑tec Silver) — Walter Tools

TCMT16T304-RM4 WSM20S is a triangular indexable insert designed for demanding machining of stainless steels and heat‑resistant superalloys

• Triangle 60° indexable insert
• Tiger‑tec Silver coating for heat resistance
• RM4 chipbreaker for controlled chips
• 7° clearance; 0.4 mm corner radius

Reliable cutting performance for difficult materials

The coated carbide grade WSM20S, part of the Tiger‑tec Silver series, is engineered to handle the thermal and mechanical demands of ISO group M (rostfreie Stähle / stainless steels) and S (superalloys and titanium). The combination of a high‑temperature resistant coating and a stable substrate promotes predictable chip formation and reduced tendency for built‑up edge, which directly lowers scrap rates and interrupts fewer production cycles. For shop floors seeking measurable process stability, this insert offers longer tool life and consistent surface quality under elevated cutting temperatures.

Geometry that balances strength and surface finish

The triangular 60° shape provides three usable cutting corners, while the 0.4 mm corner radius increases edge strength without sacrificing finish when set to appropriate feeds. The 7° clearance angle reduces rubbing and heat generation at the flank, improving dimensional repeatability on turned features. The plate thickness T3 and size designation 16 contribute to mechanical robustness in interrupted or heavy‑cut conditions. These geometric choices ensure a practical compromise between resistance to edge chipping and the capacity to achieve fine surface tolerances in stainless steels and high‑temperature alloys.

Process advantage and application focus

Equipped with the RM4 chipbreaker, the insert promotes short, manageable chips across a range of cutting parameters, aiding chip evacuation and tool‑holder life. The tolerance class M supports consistent seat fitment and repeatability during index changes. The design suits precision engineering environments and production turning operations where reproducible results and low downtime are priorities. The TCMT16T304‑RM4 insert from Walter Tools delivers a combination of thermal resistance, chip control, and mechanical stability that benefits both serial production and jobbing work on difficult‑to‑cut materials.

FAQ

What materials is this insert suited for?
The TCMT16T304‑RM4 WSM20S insert is optimised for ISO group M (rostfreie Stähle / stainless steels) and S (superalloys and titanium), where heat resistance and edge stability are essential.

How does the RM4 chipbreaker help in production?
The RM4 chipbreaker on this Walter Tools insert produces short, controlled chips that improve evacuation, reduce tool‑holder wear and support continuous, interruption‑free machining cycles.

What benefit does the Tiger‑tec Silver grade provide?
Tiger‑tec Silver coating increases thermal resistance and reduces adhesion on the cutting edge, resulting in extended tool life and more consistent surface quality when machining difficult alloys.

Is the insert available in other geometries or radii?
This SKU is a triangular 60° insert with a 0.4 mm corner radius and thickness T3; alternative geometries or radii may be available under different designations from Walter Tools.

What does tolerance class M mean for assembly?
Tolerance class M indicates a medium tolerance standard for seat fit and repeatability, ensuring reliable index changes and consistent positioning in compatible tool holders.
