DNMG110412-RM5 WMP20S — Turning indexable insert with Tiger·tec Silver for rostfreier Stahl (Walter Tools)

The DNMG110412-RM5 WMP20S is a rhombic 55° turning insert designed for reliable finishing and medium-to-robust roughing operations on rostfreier Stahl, combining a coated carbide grade with a controlled-chip RM5 geometry.

• Tiger·tec Silver coated for long edge life
• Optimised for rostfreier Stahl (ISO M)
• Rhombic 55° geometry for stable turning
• 1.2 mm corner radius for secure chip control

Greater process security through advanced coating and grade

The Tiger·tec Silver coating together with the WMP20S carbide grade provides a consistent wear pattern and improved thermal resistance, which translates into longer tool life and fewer tool changes. For workshops aiming to increase machine uptime, the combination of a wear-resistant surface and a carbide substrate ensures stable cutting edges even under elevated temperatures typical of rostfreier Stahl machining. The controlled microstructure of the coating reduces adhesive wear and delays the onset of flank wear, so cycle times stay predictable and tool-change planning becomes simpler.

Reliable chip control and surface quality when machining rostfreier Stahl

A dedicated RM5 chipbreaker and a 1.2 mm corner radius are designed to manage the challenging chip behaviour of rostfreier Stahl, which tends to form long, stringy chips and to adhere to cutting edges. The RM5 geometry promotes chip segmentation and evacuation, lowering the risk of built-up edge and improving surface finish. The negative 0° relief angle reinforces the cutting edge and aids in interrupted cuts or variable depth passes; this results in fewer stoppages for manual intervention and a more consistent part finish during serial production.

Practical benefits for workshop integration and productivity

The rhombic 55° insert form balances accessibility for profiling and face turning with a robust cutting edge for heavier cuts. As an indexable insert it simplifies inventory management: a single toolholder can accept multiple edges, reducing the number of dedicated tools required. The insert’s series and grade characteristics support predictable performance on rostfreier Stahl, helping planners to estimate tool life and machining costs with greater confidence.

FAQ

What materials is this insert suitable for?
The DNMG110412-RM5 WMP20S insert is optimised for rostfreier Stahl (ISO M) and performs reliably under medium to robust cutting conditions.

How does the Tiger·tec Silver coating benefit machining?
Tiger·tec Silver on the WMP20S grade increases thermal resistance and wear stability, which extends tool life and reduces flank wear when turning rostfreier Stahl.

What advantages does the RM5 chipbreaker provide?
The RM5 chipbreaker promotes chip segmentation and controlled evacuation, lowering built-up edge formation and improving surface finish in rostfreier Stahl applications.

Why is a 0° negative relief angle used on this insert?
A negative 0° relief reinforces the cutting edge for interrupted cuts and heavy engagement, improving edge strength and process stability during demanding turning tasks.
