DNMG110408-MM5 WMP20S indexable turning insert — Walter Tools, Tiger·tec Silver, for stainless steel

DNMG110408-MM5 WMP20S is an indexable turning insert designed for medium to robust machining of stainless steel, offering process-stable cutting under challenging conditions

• Tiger·tec Silver coating for edge stability
• WMP20S grade for stainless steel applications
• Rhombic 55° geometry for versatile turning
• 0.8 mm corner radius for robust cutting edge

Reliable cutting performance through modern coating technology

The Tiger·tec Silver coating combined with the WMP20S grade provides enhanced wear resistance and reduced friction at the cutting edge, which translates into longer tool life and fewer interruptions in the machining cycle. This technological pairing supports stable chip formation when working with stainless steel, a material group known for its tendency to work-harden and generate heat. For production planners, this means improved process reliability and predictable component quality under medium to demanding conditions.

Geometry and edge definition that support consistent surface finish

The rhombic 55° shape and the 0.8 mm corner radius create a balance between accessibility and edge robustness. The 0° negative rake increases edge strength for interrupted cuts and tougher turning operations, while the chipbreaker MM5 helps control chip flow during machining. These geometric choices reduce the risk of build-up at the edge and help maintain a consistent surface finish, especially important when producing parts that require tight visual or dimensional tolerances.

Application-focused design for stainless steel machining

This insert is specifically suited to stainless steel applications and is optimised for the thermal and mechanical challenges that these alloys present. The cutting grade is engineered to support secure chip control and a stable cutting edge in stainless steels, minimising the tendency for built-up edge and enabling repeatable results. For operators seeking predictability when machining stainless steel, this insert offers an efficient compromise between cutting performance and tool durability.

Practical compatibility and economical use in indexable tool systems

As an indexable insert in the DNMG family, the component integrates with standard holders and established turning systems; this reduces shopfloor complexity and allows straightforward stocking strategies. The combined effect of coating, grade and geometry can lower total machining cost by extending cutting intervals and reducing unplanned tool changes. For production managers, this yields measurable productivity gains and easier process planning without the need to revise existing clamping or holder inventories.
