TCMT090202-FM4 WSM20S triangle insert — Tiger‑tec Silver coated carbide by Walter Tools

TCMT090202-FM4 WSM20S is a triangle 60° indexable insert for turning and boring applications, optimised for stainless steels and heat‑resistant superalloys.

• Tiger·tec Silver coating
• Suitable for stainless steel and superalloys
• Triangle 60° insert geometry
• Corner radius 0.2 mm for fine finishes

High process reliability for difficult materials

The Tiger·tec Silver grade WSM20S combines a coated carbide substrate with a coating technology optimised for high temperature resistance and stable chip formation. This composition supports reliable machining of stainless steel and superalloys, where workpiece toughness and heat concentration can otherwise degrade performance. The FM4 chipbreaker is designed to control chip flow and reduce built‑up edge, which translates into longer tool life and fewer interruptions on the shop floor. Users benefit from predictable tool behaviour and reduced scrap rates in continuous production.

Geometry and small radius for improved surface quality

The triangular 60° shape and the corner radius 0.2 mm contribute to a balanced combination of cutting strength and surface finish. A smaller corner radius helps to achieve finer surface textures while maintaining sufficient edge support for interrupted cuts. The 7° relief angle reduces rubbing and helps maintain a sharp cutting line, especially in finishing passes. Together these geometric attributes allow the insert to deliver consistent part quality in close‑tolerance turning and boring operations.

Operational advantages and productivity gains

Applying the TCMT090202-FM4 WSM20S insert with its FM4 chipbreaker leads to improved process stability and fewer tool changes. Stable chips reduce machine downtime and simplify chip handling in automated cells. Coating performance under the Tiger·tec Silver series enhances resistance to thermal softening, which means higher cutting parameters can be used safely in many cases. The result is demonstrable productivity benefits: longer runtimes per edge and more parts produced between indexings or insert changes.

Practical application guidance and material scope

The insert is particularly suitable where ISO material groups M (stainless steels) and S (heat‑resistant superalloys and titanium) are encountered. In practice, this means milling or turning operations on austenitic stainless steels, Inconel‑type alloys and other high‑temperature materials where heat control and chip management are critical. Selecting an appropriate feed and depth of cut in conjunction with coolant strategy will exploit the WSM20S grade’s strengths; for mixed‑material batches the grade provides a reliable compromise between wear resistance and edge toughness.

FAQ

Which materials are best suited to this insert? The insert is formulated for stainless steel (ISO group M) and heat‑resistant superalloys (ISO group S); the WSM20S grade and Tiger‑tec Silver coating support machining in these demanding materials.

What role does the FM4 chipbreaker play in practice? The FM4 chipbreaker promotes controlled chip formation and reduced built‑up edge, improving edge life and surface finish when machining tougher alloys with the TCMT090202‑FM4 geometry.

How does the corner radius affect part quality? A 0.2 mm corner radius offers a compromise between cutting edge strength and the ability to achieve fine surface finishes, particularly useful for finishing passes on close‑tolerance components.

Is this insert suited for interrupted cuts? Yes; the triangle form and coating combination deliver adequate edge support and heat resistance, making the insert suitable for many interrupted cutting scenarios typical in stainless steel and superalloy machining.
