TCMT090204-FM4 WSM20S triangular indexable insert – Tiger‑tec Silver, FM4 chipbreaker | Walter Tools

The TCMT090204-FM4 WSM20S is a triangular turning and boring insert designed for demanding applications on stainless steels and heat‑resistant superalloys, offering a balance of edge stability and controlled chip formation.

• Tiger‑tec Silver coating for long tool life
• WSM20S grade for stainless and superalloys
• FM4 chipbreaker for predictable chip control
• 7° relief angle reduces cutting forces
• Triangle 60° with 0.4 mm corner radius

Consistent machining on stainless steels and superalloys

The combination of the Tiger‑tec Silver coating and the WSM20S carbide grade is engineered to withstand the thermal and mechanical stresses typical of machining stainless steels and heat‑resistant alloys. The coating increases surface hardness and thermal stability, which in turn reduces adhesive wear and the risk of built‑up edge. This results in improved tool life and fewer interruptions for tool changes, supporting steadier production cycles and reduced unit costs. The insert’s geometry facilitates safe chip formation even under elevated cutting temperatures.

Predictable chip control and improved surface finish

Built‑in features such as the FM4 chipbreaker and a 0.4 mm corner radius enable consistent chip evacuation and refined surface quality. The FM4 geometry controls chip segmentation and curl, lowering the chance of long, stringy chips that can foul workpieces and holders. The 7° relief angle helps keep cutting forces manageable, so feeds and speeds can be set with greater confidence. Together these elements contribute to a reliable, repeatable finish and less downstream rework.

Process stability that raises productivity

Applied to both superalloys and titanium, the grade and geometry offer a stable cutting edge that tolerates common interruptions in constrained operations. Stable edges mean fewer unplanned stoppages and more predictable tool life, which can be an immediate contributor to productivity gains on the shop floor. Where small improvements in cycle time and tool availability matter, this insert provides a measurable advantage through consistent performance and repeatable results.

Integration into existing tool systems and selection guidance

The triangular 60° shape provides three cutting corners per index, supporting economical use of the insert in standard turning and boring toolholders. The M tolerance class and the thickness code 02 correspond to common holder interfaces; this helps simplify procurement and integration into existing tool inventories. For application‑specific recommendations—such as optimal cutting data for particular stainless grades or superalloys—technical guidance is available to ensure the chosen insert and parameters match the machining challenge.
