TCMT16T304-RM4 WSM10S turning insert — Walter Tools, Tiger·tec Silver grade, RM4 chipbreaker

The TCMT16T304-RM4 WSM10S is a coated turning and drilling insert designed for heavy-duty machining of stainless steel and heat-resistant alloys, offering stable cutting edges and consistent chip control in demanding production environments

• Tiger·tec Silver coating performance
• Optimised for stainless steel and superalloys
• Triangle 60° insert with 0.4 mm corner radius
• RM4 chipbreaker for secure chip control

Reliable edge integrity for challenging materials

The Tiger·tec Silver grade WSM10S is formulated as a coated cemented carbide designed to withstand the thermal and mechanical stresses typical of machining stainless steel and high-temperature alloys. The combination of coating technology and carbide substrate increases resistance to heat and flank wear, which results in improved edge life and fewer tool changes. For process planners this translates into steadier cycle times and a reduced risk of built-up edge when confronting long, continuous cuts or interrupted feeds.

Predictable chip formation and stable machining

Equipped with an RM4 chipbreaker, the insert provides controlled chip shaping that supports safe evacuation of swarf in both turning and bore‑facing operations. The chipbreaker geometry promotes short, manageable chips under a wide range of cutting conditions, reducing the chance of entanglement and improving surface quality. As a direct benefit, machine downtimes related to chip clearing are minimised and operator handling becomes simpler, enhancing overall shop-floor efficiency.

Compact geometry for versatile tool set-up

The triangle 60° form and 0.4 mm corner radius deliver a balance between robustness and cutting precision. The triangular shape enables three effective cutting edges per indexable plate, while the modest corner radius supports fine surface finishes without sacrificing edge strength. A relief angle of 7° helps maintain an accurate cutting profile and reduces rubbing at the flank, which is particularly useful when addressing narrow shoulders or tight tolerances in shafts and bores.

Application guidance and process benefits

This insert is specified for S / M applications — that is, for heat-resistant superalloys and stainless steel — and is therefore recommended where high thermal loads and material ductility challenge standard grades. The coated design and dedicated chipbreaker mean the insert performs well under higher cutting speeds and in operations requiring consistent surface integrity. Process engineers will appreciate the grade’s focus on repeatable performance, enabling predictable tool life forecasts and straightforward sort allocation in production planning.

FAQ

What materials is this insert suitable for?
The TCMT16T304-RM4 WSM10S insert is specified for S and M groups, meaning it is suitable for heat-resistant superalloys and stainless steel, offering thermal stability and controlled wear behaviour.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker shapes chips into short, controllable segments, improving swarf evacuation and lowering the risk of chip entanglement during turning and drilling operations with the insert.

What advantages does the Tiger·tec Silver grade provide?
Tiger·tec Silver (WSM10S) combines a robust coated substrate with thermal-resistant properties, delivering longer tool life and consistent edge behaviour when machining challenging materials.

Can the triangle geometry be indexed multiple times?
Yes, the triangle 60° form provides three usable cutting edges per insert, enabling cost-effective indexing and straightforward edge replacement during scheduled tool maintenance.

Is this insert suitable for finishing passes?
With a 0.4 mm corner radius and the 7° relief angle, the insert is capable of producing good surface finishes in semi-finish and certain finish operations when cutting parameters are optimised.
