DNMG110404‑MM5 WMP20S Turning insert — Tiger·tec Silver for rostfreier Stahl by Walter Tools

The DNMG110404‑MM5 WMP20S is an indexable turning insert engineered for medium to robust machining of rostfreier Stahl, providing reliable chip control and consistent cutting-edge performance in general turning applications.

• Tiger·tec Silver coating for stable edges
• Optimised for rostfreier Stahl (ISO M)
• Rhombic 55° insert with 0.4 mm corner radius

Consistent process security through advanced coating technology

The Tiger·tec Silver series combines a coated carbide substrate with targeted surface engineering to reduce flank wear and support repeatable performance under difficult conditions. As a coated grade, WMP20S improves heat resistance and contributes to stable chip formation, which lowers the risk of built‑up edge when machining rostfreier Stahl. This results in fewer interruptions for tool changes and a more predictable production rhythm, helping to maintain throughput on multi‑shift operations.

Geometry that improves surface quality and edge strength

The rhombic 55° format and the negative 0° relief angle give this insert high rigidity and reliable seating in the toolholder, while the 0.4 mm corner radius balances edge strength with the ability to produce good surface finish. The integrated MM5 chipbreaker is designed to control chips in a wide range of feeds, reducing the likelihood of long, stringy swarf and improving chip evacuation. Together, these features allow stable cuts with consistent part quality and reduced secondary finishing.

Shop‑floor benefits: productivity, repeatability and tool life

Designed for moderate to heavy conditions typical for rostfreier Stahl, the grade supports secure material removal rates and extended tool life thanks to its wear‑resistant coating and robust edge geometry. The insert’s dimensions and form enable straightforward toolholder selection and quick indexation, which minimises setup time and contributes to overall process economy. Using a proven series from a recognised supplier reduces variability between batches and supports predictable maintenance planning.
