SNMG190616-RM5 WSM20S indexable turning insert — square 90°, Tiger·tec Silver, Walter Tools

SNMG190616-RM5 WSM20S is a square turning insert designed for machining stainless steels and heat-resistant superalloys with a focus on secure chip control and consistent tool life

• Tiger·tec Silver coating technology
• Optimised RM5 chipbreaker for long chips
• Square 90° form for high edge strength
• 1.6 mm corner radius for balance of strength and finish

High-performance machining for demanding materials

The WSM20S grade, part of the Tiger·tec Silver range, combines a coated carbide substrate with a thermally resilient coating to address the challenges of machining stainless steels and superalloys. The coating improves wear resistance and reduces adhesion of workpiece material to the cutting edge, which in practice means fewer edge build-ups and steadier cutting forces. The insert’s negative relief angle and robust square form deliver a stable cutting geometry that tolerates higher feed rates and interrupted cuts, supporting predictable cycle times in production.

Reliable chip control and surface quality

The dedicated RM5 chipbreaker is shaped to produce controlled, segmented chips when cutting tough, low-thermal-conductivity materials. This results in safer chip evacuation, reduced risk of surface damage, and a more stable cutting zone. The 1.6 mm corner radius is selected to withstand heat and mechanical loads while still enabling acceptable surface finish; where a finer finish is required, the same geometry allows easy adjustment of feed to trade material removal rate for improved surface integrity. These design choices support consistent part tolerances and fewer reworks.

Practical compatibility and application guidance

The square 90° plate offers multiple indexed edges to lower tooling costs per edge and to increase uptime. The geometry and grade suit turning operations where robustness is prioritised—roughing and mixed semi-finishing in particular—on materials classified under ISO group M (stainless steels) and S (heat-resistant superalloys and titanium). The designation SNMG190616-RM5 indicates the insert family and chipbreaker; pairing with appropriate toolholders and cutting parameters tailored to the workpiece alloy will achieve the best life and productivity. For application-specific parameters and process windows, Metav Werkzeuge can provide machining data and recommendations.
