TCMT16T304-FM6 WSM20S indexable turning insert – FM6 chipbreaker, Tiger·tec Silver (Walter Tools)

The TCMT16T304-FM6 WSM20S is an indexable turning insert designed for reliable machining of stainless steels and heat‑resistant superalloys in demanding turning operations.

• Tiger·tec Silver coating for high process security
• Grade WSM20S for stainless and heat‑resistant alloys
• Triangle 60° form with 0.4 mm nose radius
• 7° clearance angle, T3 plate thickness

Consistent chip control when machining difficult materials

The insert’s WSM20S grade, part of the Tiger·tec Silver series, is formulated for materials that generate heat and tend to work‑harden. This leads to stable chip formation and helps avoid built‑up edge, which in turn reduces unscheduled downtime. The coated carbide substrate improves thermal resistance and wear behaviour so that the cutting edge maintains its geometry for longer. For production environments that demand reproducible results, this combination delivers measurable gains in process reliability and component quality.

Geometry that supports surface finish and dimensional accuracy

A triangle 60° plate form with a 0.4 mm nose radius provides a predictable cutting edge for both light finishing passes and more demanding semi‑finishing work. The FM6 chipbreaker is optimised to break and evacuate chips from the cutting zone, reducing the risk of surface defects and improving tool stability. The modest clearance of 7° and the T3 plate thickness ensure secure clamping in standard indexable toolholders while minimising vibration—advantages that translate directly into improved surface quality and repeatable dimensions.

Productivity and tool life for cost‑efficient batch production

Designed for high‑duty cycles in rust‑resistant steels and superalloys, the insert balances cutting-edge robustness with predictable wear behaviour. The coated surface reduces thermal and abrasive wear, contributing to long tool life and fewer indexings per component batch. This reliability supports shorter cycle times and lower per‑part tooling costs across repetitive production runs. Choosing coated carbide inserts like this one typically reduces changeover frequency and increases effective machine availability.

Practical application notes and compatibility

The insert is suitable for a range of turning tasks on conventional and CNC lathes where stainless steels and heat‑resistant alloys are present. Its ISO designation ensures compatibility with standard triangular indexable holders sized for 16 mm plates. While specific cutting parameters depend on the workpiece alloy, machine rigidity and coolant strategy, the geometry and chipbreaker make the insert a versatile choice for both roughing and controlled finishing.
