RCMT060300-RM4 WSM20S indexable turning insert for stainless steel and superalloys | Walter Tools, Tiger‑tec Silver

The RCMT060300-RM4 WSM20S is an indexable turning insert designed to machine rostfreiem Stahl (stainless steel) and high‑temperature superalloys, featuring the Tiger‑tec Silver coating and an RM4 chipbreaker for controlled swarf formation.

• Tiger‑tec Silver coating for high temperatures
• Optimised RM4 chipbreaker for secure chip control
• Round insert, 0 radius, 7° relief angle
• Suitable for stainless steel and superalloys

Higher productivity when machining stainless steel and superalloys

The coated grade from the Tiger‑tec Silver family delivers a balance between thermal stability and wear resistance, which is essential when turning stainless steel and heat‑resistant alloys. The chemistry and multilayer architecture of the coating slow crater wear and support a stable cutting edge, reducing the need for frequent index changes. As a result, cycle times remain predictable and tool cost per component is lowered through improved tool life and fewer interruptions.

Geometry and chip control that protect the cutting edge

The RM4 chipbreaker is designed to produce short, manageable chips in sticky or work‑hardening materials. Combined with the round insert shape and a 0 corner radius, it enables light to medium turning operations with consistent contact conditions. The 7° relief angle reduces rubbing and minimises heat transfer into the flank face, which helps to prevent built‑up edge and supports reproducible surface finish. In practical terms, this means fewer rejects and a steadier process window on challenging alloys.

Robust grade and repeatable performance

The WSM20S grade is a coated cemented carbide tailored for materials classified M and S (stainless steels and superalloys/titanium). Its formulation emphasises edge strength and thermal resistance so that the insert withstands the abrasive and adhesive wear mechanisms typical of such workpieces. This translates into process reliability on longer runs and when machining components with variable heat generation, for example interrupted cuts or thin‑wall features.

How to integrate the insert for best results

Select appropriate cutting parameters aligned with the material and part geometry: moderate cutting speeds for stainless steels, reduced feed or depth of cut where deflection or chatter is a risk, and sufficient coolant or minimum quantity lubrication where thermal control is required. The insert’s small size and tolerance class M make it suitable for precision turning and for applications demanding tight repeatability. For custom clamping or holder choices, refer to standard indexable holder specifications that accept RCMT‑style inserts.

FAQ

What materials is this insert designed for?
The RCMT060300-RM4 WSM20S insert is intended primarily for stainless steel and heat‑resistant superalloys, where its coating and substrate provide thermal and edge resilience.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker promotes short, controlled chips in sticky and work‑hardening materials, improving swarf handling and helping maintain a clean cutting zone with stable edge life.

Is the insert suitable for finishing or roughing operations?
With its round shape and 0 corner radius, the insert suits light to medium finishing and semi‑finishing; parameter adjustments permit modest roughing, but heavy stock removal may require a different geometry.

Which coating benefits should be expected from Tiger‑tec Silver?
Tiger‑tec Silver offers enhanced thermal stability and wear resistance compared with uncoated grades, enabling longer tool life and steadier surface quality on demanding alloys.
