DCMT11T308-RM4 WSM30S turning insert — Tiger·tec Silver, Walter Tools

The DCMT11T308-RM30S WSM30S is a rhombic 55° turning insert designed for secure chip control and stable cutting when machining rostfreie Stähle and high-temperature alloys in production environments.

*Tiger·tec Silver coated carbide grade WSM30S
*Optimised RM4 chipbreaker for secure chip control
*Rhombic 55° insert with 0.8 mm corner radius
*7° clearance angle for stable cutting geometry

High-performance cutting for difficult-to-machine materials

The coated carbide grade WSM30S from Walter Tools is developed for demanding cuts in rostfreie Stähle and heat-resistant superalloys. Its combination of a tough substrate and the Tiger·tec Silver coating increases resistance to thermal and mechanical loading, which translates into longer intervals between indexings and fewer tool changes. For production, this means better process stability and predictable component tolerances when machining materials that typically cause built-up edge or rapid tool wear.

Geometry that ensures consistent chip control and surface quality

The insert’s RM4 chipbreaker is engineered to break and evacuate chips reliably under a range of cutting conditions, reducing the risk of entanglement and improving surface integrity. The rhombic 55° shape offers positive cutting engagement for facing and turning operations, while the 0.8 mm corner radius balances edge strength with achievable surface finish. Together, these geometric choices contribute to repeatable results and reduced secondary operations.

Coating and grade for extended tool life and productivity

The Tiger·tec Silver coating provides a thermal barrier and improved friction characteristics, which help maintain a stable cutting edge even under elevated temperatures typical of machining stainless steels and nickel-based alloys. The coated carbide composition promotes reliable chip formation and supports higher cutting speeds where process planning allows, resulting in better throughput without sacrificing component quality.

Practical integration into machining workflows

Available in the common DCMT format with T3 thickness and size 11, this insert fits many standard toolholders and clamping systems, simplifying stocking and tool change procedures. The combination of robust edge geometry and coating technology is particularly suitable for batch production and mixed-series machining where consistency and predictable tool life reduce downtimes and planning overhead.
