DCMT070204-RM4 WMP20S Drehwendeschneidplatte – Tiger‑tec Silver, for stainless steel (Walter Tools)

The DCMT070204-RM4 WMP20S is a rhombic 55° indexable insert designed for robust turning of stainless steel, offering a balance of wear resistance and reliable chip formation for medium to heavy-duty applications.

• Tiger‑tec Silver coated carbide grade WMP20S
• RM4 chipbreaker for stable chip control
• Rhombic 55° geometry for versatile turning
• 7° clearance and 0.4 mm corner radius

Higher process efficiency with a wear-resistant grade

The coated carbide WMP20S grade, developed within the Tiger‑tec Silver series, delivers a predictable tool life under the thermal and adhesive conditions typical of stainless steel machining. The combination of a modern PVD/CVD-style coating and a stable substrate reduces flank wear and builds resistance to heat-related edge deterioration. This translates into longer intervals between index changes and fewer unscheduled tool interventions, improving overall machine utilisation and lowering per-part tooling cost.

Reliable chip control and consistent surface quality

The RM4 chipbreaker is optimised for secure chip formation in tough-to-cut alloys, promoting manageable chip geometries and safe evacuation from the cut. Stable chip control reduces the risk of built-up edge and improves repeatability of part dimensions. As a result, operators obtain improved surface finishes and can maintain tighter tolerances with fewer reworks, particularly when turning ferritic or austenitic stainless grades that are prone to material adhesion.

Geometry and clearance tuned for flexible turning

The rhombic 55° insert shape and a 7° clearance angle permit a wide range of turning strategies, from light finishing passes to more demanding profiling tasks. The 0.4 mm corner radius supports robust edge strength while allowing for acceptable surface integrity on the workpiece; it is a compromise between edge stability and fine-finish capability. This geometry is suitable for standard toolholders using DCMT‑style inserts and supports both conventional and climb turning methods when process parameters are set accordingly.

Application guidance for repeatable results

This indexable insert is intended primarily for use on stainless steel (ISO group M) under medium to robust cutting conditions. Matching the insert with appropriate cutting speeds, feeds and coolant strategy is essential: lower cutting speeds and stable feed rates commonly reduce the tendency for built-up edge, while the coated grade helps withstand thermal loading. For machining programmes that demand predictable life and constant surface quality, the insert offers a dependable combination of wear resistance and chip management.
