VCMT160412-RM4 WSM20S Turning Insert – Tiger·tec Silver coating, for stainless steel and superalloys by Walter Tools

A VCMT160412-RM4 WSM20S turning insert designed for demanding interrupted cuts and continuous production where predictable tool life and secure chip control are required

• Tiger·tec Silver coating for enhanced edge life
• Optimised RM4 chipbreaker for stable chips
• 7° clearance and 1.2 mm corner radius
• Suited to stainless steel and superalloys

Improved productivity when machining difficult-to-cut alloys

The coated carbide grade WSM20S, built on Walter Tools’ Tiger·tec Silver technology, provides a reliable balance between wear resistance and toughness. This makes it especially suitable for machining stainless steel and heat‑resistant alloys (ISO groups M and S). The result is consistent edge stability, which reduces the frequency of tool changes and contributes directly to higher component throughput. For users seeking measurable process improvements, the combination of a robust coating and an application‑oriented chipbreaker supports longer uninterrupted cycles and fewer quality interruptions.

Reliable chip control and surface quality with optimised geometry

The insert’s RM4 chipbreaker is engineered to form short, controllable chips under typical turning conditions for challenging materials. Together with the rhombus 35° geometry and 7° clearance, this leads to lower cutting forces in many applications and a more predictable cut. The corner radius 1.2 mm balances strength at the cutting edge with achievable surface finish, so machinists gain both process reliability and improved part aesthetics. The term “chipbreaker” here denotes the micro‑geometry that shapes and breaks chips to prevent entanglement and protect the workpiece surface.

Practical benefits for workshop efficiency and tool handling

The insert format is industry‑standard and compatible with a wide range of toolholders, enabling simple integration into existing toolsets. The coated carbide construction of this turning insert supports productive machining across a broad material spectrum while maintaining stable cutting edges in continuous production. By selecting a purpose‑matched grade such as WSM20S, procurement teams and process engineers can reduce set‑up variability and focus on optimising cutting data rather than compensating for premature wear. This leads to lower downtime and a clearer return on tooling decisions.
