TPMT16T304-FM4 WSM20S triangular indexable insert — Tiger·tec Silver, for stainless steels and superalloys (Walter Tools)

The TPMT16T304-FM4 WSM20S is a triangular 60° indexable insert engineered for demanding turning of stainless steels and heat-resistant superalloys, offering stable cutting through a combination of coated carbide and a geometry tuned for secure chip formation.

• Tiger·tec Silver coating performance
• Suitable for stainless steels and superalloys
• Triangular 60° shape for three cutting edges
• FM4 chipbreaker for controlled chips

High-performance coating for heat and wear resistance

The coated-carbide grade WSM20S, part of the Tiger·tec Silver series, is formulated to withstand the thermal and mechanical stresses typical of machining stainless steels and nickel-based alloys. The advanced coating provides improved heat resistance and wear behaviour, which translates into longer edge life and fewer tool changes. This results in more predictable cycle times and a reduction in unplanned downtime, supporting a more efficient production flow.

Geometry that balances stability and surface quality

A triangular 60° insert with a corner radius of 0.4 mm and 11° clearance delivers a compromise between strength and finish. The modest corner radius reduces cutting forces while still enabling a good surface appearance in medium to light turning operations. The insert thickness T3 contributes to seat stability in the toolholder, helping to maintain repeatable part tolerances and reduce vibration during machining of tough materials.

Chip control designed for difficult materials

The FM4 chipbreaker is tuned for secure chip formation when turning ductile and work-hardening materials. In combination with the coated substrate, the chipbreaker supports consistent swarf removal and lowers the risk of built-up edge, which is a common issue when machining corrosive or heat-resistant alloys. Improved chip control also facilitates safer automated operations and simplifies swarf management at the machine.

Process reliability and economical productivity

The combination of the WSM20S grade and cutter geometry aims to offer high process reliability in production environments. Fewer interruptions for index changes and predictable tool life contribute to lower overall machining costs. The insert’s design is suitable for shops that require consistent performance on challenging materials while keeping setup and rework effort to a minimum.
