DCMT11T312-RM4 WMP20G indexable turning insert for stainless steel, Tiger·tec Gold | Walter Tools

The DCMT11T312-RM4 WMP20G is an indexable turning insert designed for medium to robust stainless steel applications, offering a Rhombus 55° geometry and optimised chip control for stable, repeatable machining

• Tiger·tec Gold coating for enhanced wear resistance
• Optimised RM4 chipbreaker for stable chip control
• Designed for stainless steel machining (ISO M)
• Rhombus 55° geometry with 7° clearance

Consistent performance for stainless steel turning

The insert’s Tiger·tec Gold coating and carbide substrate deliver wear resistance and thermal stability that directly support consistent production cycles when machining stainless steel. The coated grade reduces flank wear under high cutting temperatures, which means fewer tool changes and improved process reliability. For shops requiring predictable component finish and dimensional stability, the combination of a coated carbide grade and a proven chip control geometry reduces the risk of build-up and rework while maintaining machining productivity.

Reliable chip control that keeps production running

Equipped with the RM4 chipbreaker, this indexable insert ensures controlled chip formation and evacuation in demanding turning operations. A stable chipflow prevents entanglement and minimises downtime for cleaning or manual intervention, supporting uninterrupted batch runs. The chipbreaker design also contributes to improved surface results and reduced tooling loads, which together enhance cutting efficiency and reduce cycle times on long production runs.

Durable edge geometry for repeatable results

The Rhombus 55° shape with a 1.2 mm nose radius and 7° clearance offers a balance between strength and finishing capability. The nose radius provides robustness in interrupted cuts and a consistent cutting edge for toleranced features, while the clearance angle reduces rubbing and heat generation. These geometry choices lead to a stable cutting edge that preserves part quality across multiple indexings, translating into better overall tool economy.

Practical advantages for workshop integration

The insert’s format and tolerance class M simplify toolholder selection and repeatable seating, reducing setup time during tool changes. The grade is specified for medium to robust stainless steel conditions (ISO M), supporting a wide range of components from medical parts to food-industry fittings. With clear specifications and an industry-proven coating, this solution enables process planners to standardise tooling for improved inventory control and predictable machining outcomes.
