TCMT16T308-RM4 WSM20S triangular indexable insert – Walter Tools, Tiger‑tec Silver, for stainless steels and superalloys

The TCMT16T308-RM4 WSM20S is a triangular indexable insert designed for turning, boring and related operations, optimised for machining stainless steels and heat‑resistant superalloys.

• Tiger‑tec Silver coated carbide technology
• Optimised for stainless steels and superalloys
• RM4 chipbreaker for secure chip control
• Triangular 60° insert with 0.8 mm corner radius

Consistent cutting in tough materials for greater process reliability

The WSM20S grade, applied within the Tiger‑tec Silver series, is a coated carbide blend engineered to maintain a stable cutting edge under high thermal and mechanical stress. This composition enhances chip control and reduces edge build‑up when working with stainless steels, materials that commonly cause work hardening and elevated temperatures. The result is fewer unplanned interruptions, longer tool life and a more predictable production cadence—advantages that directly benefit cycle time and part quality in serial or batch production.

Geometry that protects the cutting edge and improves surface finish

A triangular 60° format combined with a 0.8 mm corner radius and a 7° relief angle provides a balanced geometry for durable edge strength and reliable contact conditions. The RM4 chipbreaker promotes manageable chip formation, especially under variable cutting conditions, which contributes to consistent surface appearance and repeatable dimensional results. The T3 plate thickness and the insert’s tolerance class M support secure clamping and minimise micro‑vibration, translating into improved process stability on CNC lathes and turning centres.

Practical advantages that support productive machining

Integrating this insert into turning or boring operations delivers a pragmatic efficiency uplift: the Tiger‑tec Silver coating reduces friction and enhances heat resistance, while the substrate and chipbreaker sustain cutting performance across tougher alloys. For workshops seeking reduced downtime and dependable batch quality, the insert’s features enable longer tool life and stable cutting forces, which together lower total machining costs and help maintain predictable throughput in demanding applications.

FAQ

What materials is this insert suited for?
The TCMT16T308‑RM4 WSM20S insert from Walter Tools is formulated for stainless steels (ISO group M) and for heat‑resistant superalloys and titanium alloys (ISO group S), offering stable chip formation and thermal resilience.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker on the TCMT16T308‑RM4 promotes controlled chip fragmentation and evacuation, reducing the risk of entanglement and improving surface integrity during machining of tough materials.

Can this insert deliver consistent tool life in serial production?
Yes; the combination of Tiger‑tec Silver coating and the WSM20S grade provides improved wear resistance and edge stability, supporting predictable tool life and repeatability in serial machining operations.

Which insert geometry ensures dimensional stability?
The triangular 60° form with a 0.8 mm corner radius and a 7° relief angle gives the insert robust edge strength and stable contact, which helps maintain dimensional accuracy and surface finish under varying cutting conditions.

Is the TCMT16T308‑RM4 WSM20S compatible with standard toolholders?
The TCMT ISO format follows common indexable insert standards, and the TCMT16T308‑RM4 WSM20S fits holders designed for TCMT inserts; verification with the chosen holder and clamping system is recommended.
