VCMT110308-RM4 WSM30S — Turning insert (Rhombic 35°, 7° clearance) by Walter Tools

A VCMT110308-RM4 WSM30S turning insert designed for demanding turning of rostfreier Stahl and heat-resistant alloys, combining the Tiger·tec Silver coating technology with an RM4 chipbreaker for steady material removal.

• Tiger·tec Silver coated carbide grade
• Optimised RM4 chipbreaker for tough materials
• Rhombic 35° form, 0.8 mm corner radius
• 7° clearance angle for reliable performance

Higher productivity through tailored grade and coating

The combination of the Tiger·tec Silver coating and the WSM30S grade promotes high process stability when machining challenging alloys. The coated carbide construction reduces flank wear and supports a long tool life even under elevated temperatures typical for rostfreier Stahl and superalloys. As a consequence, cycle times can be shortened and part quality remains more consistent, which benefits batch production and mixed-series machining alike. The insert’s design focuses on repeatable cutting performance and reduced down-times.

Secure chip control and edge security for difficult materials

Equipped with the RM4 chipbreaker and a controlled geometry, the insert provides secure chip control during interrupted cuts and continuous heavy cuts. The Rhombic 35° form and 0.8 mm corner radius combine to offer robust edge strength while maintaining good accessibility in shoulder and profiling operations. For materials that are prone to workhardening or poor heat conductivity—such as rostfreier Stahl, superalloys and titanium—the geometry helps avoid built-up edge and supports predictable machining behaviour, improving surface integrity and reducing rework.

Practical implications for shop-floor use and process planning

The slim clearance of 7° contributes to a stable cutting angle and reduced rubbing, which supports consistent dimensional accuracy and surface finish. The insert’s thickness code and size are compatible with common toolholder systems for straightforward integration into existing turning setups. Selection of coated carbide grades like this one allows higher cutting speeds where coolant or process strategies permit, balancing efficiency and tool life. For series-sensitive production, the insert’s stable cutting edge minimises variation between components and simplifies tool-change scheduling.
