DCMT11T304-MM4 WMP20S — indexable turning insert for stainless steel by Walter Tools

The DCMT11T304-MM4 WMP20S is an indexable turning insert engineered for machining stainless steel under medium to robust cutting conditions, offering controlled chip formation and stable edge performance.

• Tiger·tec Silver coating for robust performance
• Optimised MM4 chipbreaker for stable chip control
• Rhombic 55° form with 0.4 mm corner radius
• Designed for stainless steel machining

Consistent cutting in challenging stainless steel applications

The combination of the Tiger·tec Silver coating and the WMP20S grade is tailored to the demands of stainless steel turning. The coating reduces friction and improves thermal stability, which helps to avoid built-up edge and premature flank wear during difficult cuts. As a result, process reliability is increased and the number of interrupted production cycles is reduced. For production planners this translates into a more predictable tool life and fewer changeovers, supporting leaner machining routines.

Geometry that supports surface quality and repeatability

The Rhombic 55° shape with a 0.4 mm corner radius and 7° relief angle provides a balance between strength and edge sharpness. The modest corner radius helps produce a consistent surface finish while maintaining edge robustness in interrupted cuts or harder zones of workpieces. The MM4 chipbreaker is optimised to generate short, controllable chips on stainless steels, minimising chip entanglement and contributing to safer, cleaner machining operations. These geometry choices reduce the need for secondary finishing and support reproducible part tolerances.

Productivity benefits and economical tool management

As an indexable insert, the insert offers quick indexation and predictable reuse of cutting edges, lowering tooling costs per part compared with brazed tools. The T3 thickness and stable tolerance class ensure secure clamping and minimal vibration, which in turn reduces tool wear and improves component consistency. The grade’s suitability for corrosion-resistant alloys means fewer tool variants are required on the shop floor when processing diverse stainless steel grades, simplifying inventory and improving setup efficiency.
