TCMT16T304-RM4 WSM30S — turning/boring indexable insert (Tiger·tec Silver) by Walter Tools

A TCMT16T304-RM4 WSM30S triangular insert engineered for heavy-duty cutting of stainless steel and heat-resistant superalloys, suited to turning and boring applications where chip control and tool life are decisive

• Tiger·tec Silver coated grade WSM30S
• Optimised RM4 chipbreaker for stable chips
• Triangular 60° shape with 0.4 mm radius
• Designed for stainless and superalloys

Consistent performance for tough-to-cut materials

The combination of the WSM30S coated carbide grade and the Tiger·tec Silver technology provides reliable wear resistance and improved thermal stability during machining of austenitic stainless steel and high-temperature alloys. The coating system reduces diffusion and protects the cutting edge under elevated temperatures, which in turn extends productive tool life. This results in fewer interruptions for insert changes and a more predictable process window, supporting sustained throughput in batch and single-piece production alike.

Reliable chip control and surface quality

The RM4 chipbreaker geometry is designed to produce short, controllable chips when machining sticky or work-hardening materials. Controlled chip formation reduces the risk of chip entanglement and protects the workpiece surface, helping to maintain consistent finish quality. For operations where surface integrity and repeatability matter, the combination of chipformer and coated substrate supports steady cutting forces and minimises unwanted built-up edge formation.

Geometry optimised for secure clamping and edge strength

The insert’s triangular 60° shape with a corner radius of 0.4 mm and a 7° relief angle balances edge strength with versatility in turning and boring setups. The T3 plate thickness and standard ISO designation make the insert compatible with a wide range of standard tool holders, ensuring stable seating and repeatable indexability. Robust geometry contributes to shock resistance and predictable wear patterns, which simplifies process planning and tool-change intervals.

Practical benefits for workshop productivity

Adopting this grade and geometry can shorten setup validation time and improve tool life in series production. The insert is particularly suitable for components made from stainless steel and nickel-based alloys where thermal loads and tenacity compromise conventional grades. By choosing this combination of coating and chip control, machining cycles become more economical through reduced downtime, less scrap and more consistent dimensional stability on finished parts.

FAQ

What materials is this insert suitable for?
The TCMT16T304-RM4 WSM30S insert is designed primarily for stainless steel (ISO group M) and also for heat-resistant superalloys and titanium (ISO group S), offering thermal stability and controlled chip formation.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating enhances thermal resistance and reduces diffusion wear on the cutting edge, which increases tool life and maintains cutting performance under elevated temperatures when machining tenacious materials.

Which tool holders are compatible with this triangular insert?
Standard ISO tool holders for triangular turning/boring inserts that accept a 16 mm inscribed size and T3 thickness are compatible; the insert’s geometry ensures secure clamping and repeatable indexing.

What advantage does the RM4 chipbreaker provide?
The RM4 chipformer produces short, controllable chips that reduce entanglement and help protect the workpiece surface, improving process security and finish consistency in demanding materials.

Is the corner radius suitable for finishing operations?
With a 0.4 mm corner radius, the insert balances edge strength and surface finish capability; it is suitable for a range of semi-finishing and light-finishing conditions depending on cutting parameters.
