VCMT110308-RM4 WSM20S – Turning indexable insert, Tiger·tec Silver, Rhombus 35° | Walter Tools

The VCMT110308-RM4 WSM20S is a rhombic 35° turning insert designed for machining stainless steels and heat-resistant superalloys with reliable chip control and high edge stability.

• Tiger·tec Silver coated carbide grade WSM20S
• RM4 chipbreaker for controlled chip formation
• Optimised for stainless steels (ISO M)
• Rhombic 35° shape with 0.8 mm corner radius
• Relief angle 7° for robust cutting edges

Stable chips and longer tool life for difficult materials

The combination of the RM4 chipbreaker and the Tiger·tec Silver coating delivers stable chip formation and consistent cutting behaviour when machining materials that tend to work-harden or produce stringy chips. The chipbreaker promotes short, controllable chips which reduce the risk of re-cutting and protect the machine‑tool environment. As a result, the insert supports longer tool life and fewer interruptions in continuous production, translating into measurable process efficiency and lower overall machining cost.

Geometry and edge preparation optimised for stainless and superalloys

Built with a Rhombus 35° profile and a 0.8 mm corner radius, this insert balances edge strength and access for moderate‑depth turning operations. The relief angle of 7° improves edge shear strength while reducing rubbing and built-up edge on stainless steels (ISO M) and superalloys/titanium (ISO S). The insert’s tolerance class M ensures consistent fit and repeatable seating in clamping systems, supporting stable cutting parameters and predictable surface quality across batches.

Process benefits, handling and predictable performance

The insert format VCMT110308‑RM4 is suitable for standard toolholders and offers straightforward indexability for fast tool changes. The WSM20S grade, part of the Tiger·tec Silver family, is a coated carbide developed to withstand thermal and mechanical stresses typical of demanding stainless‑steel turning. This results in reliable edge stability, reduced downtime for tool changes and a more predictable machining window—advantages that improve component consistency and support high productivity in jobbing and serial production alike.
