TCMT110208-RM4 WSM20S indexable turning insert — Walter Tools, Tiger‑tec Silver coating for stainless steels and superalloys

A TCMT110208-RM4 WSM20S indexable turning insert engineered for stable cutting performance when machining rostfreier Stahl and high‑temperature alloys, suitable for demanding turning and boring operations

• Tiger‑tec Silver coating for high thermal resistance
• Optimised RM4 chipbreaker for secure chip control
• Triangle 60° form with 0.8 mm corner radius

Reliable machining of challenging alloy groups

The insert’s core advantage lies in the combination of a Tiger‑tec Silver coated substrate and the WSM20S grade, formulated for high thermal stability when cutting rostfreier Stahl and superalloys. The coating reduces adhesive wear and supports consistent edge integrity under elevated temperatures, which in turn minimises unexpected downtime. For production environments where material weld‑on and edge build‑up are frequent, this specification delivers measurable improvements in process repeatability and component finish.

Controlled chip formation for safer operations

Equipped with the RM4 chipbreaker, the triangular insert produces short, controllable chips that clear reliably from the cutting zone. Stable chip control reduces the risk of entanglement and improves surface quality in serial turning operations. The insert’s geometry — a triangle 60° form with a 0.8 mm corner radius — balances strength at the cutting edge with the ability to achieve fine surface finishes; the small corner radius supports accurate part tolerances without sacrificing edge stability.

Designed for longevity and predictable tool life

The substrate and coating pairing of this grade emphasise resistance to thermal and mechanical wear mechanisms common in machining heat‑resistant superalloys and titanium alloys. The insert’s 7° relief angle promotes effective cutting engagement while limiting flank contact and rubbing, thereby extending achievable tool life. In practice, this translates into fewer insert changes per shift and improved uptime for turning cells where consistent performance is essential.

Practical integration and machining guidance

The insert is delivered in the standard TCMT110208‑RM4 geometry and thickness, enabling straightforward integration into existing toolholders designed for triangular indexable inserts. For best results, pair the insert with stable clamping and a toolholder that supports positive chip evacuation. When processing rostfreier Stahl, favour moderate cutting speeds and ensure adequate coolant or lubricant strategy as the grade prioritises thermal resilience over extreme speed machining. The specification supports machining strategies that prioritise reproducibility and surface integrity.

FAQ

What materials is this insert suited for?
The TCMT110208‑RM4 WSM20S insert is suitable for rostfreier Stahl (ISO group M) and heat‑resistant superalloys and titanium (ISO group S), reflecting the WSM20S grade focus on thermal and edge stability.

Can the insert be used for finishing passes?
Yes, the 0.8 mm corner radius and the triangular form allow for controlled finishing operations where good surface quality and repeatability are required.

What is the function of the RM4 chipbreaker?
The RM4 chipbreaker is engineered to produce short, manageable chips that aid evacuation and reduce the risk of chip entanglement in turning operations.

Is this insert compatible with standard TCMT toolholders?
The insert follows the TCMT110208 geometry and thickness specifications and is compatible with corresponding toolholders designed for triangular indexable inserts.

Does the Tiger‑tec Silver coating support high cutting speeds?
The Tiger‑tec Silver coating improves thermal resistance and edge life; while it enables robust performance at elevated temperatures, optimal cutting speeds depend on the specific workpiece alloy and machining setup.
