DNMG150604-MM5 WMP20S – Indexable turning insert with Tiger·tec Silver coating for stainless steel (Walter Tools)

DNMG150604-MM5 WMP20S is an indexable turning insert optimised for machining stainless steel in medium to robust cutting conditions, featuring a rhombic 55° geometry and a stable chip control design.

Precision and process stability for stainless-steel turning

The indexable turning insert is engineered to address the typical challenges of stainless-steel machining: work-hardening, built-up edge and elevated temperatures. The WMP20S grade, part of the Tiger·tec Silver family, combines a wear-resistant coated carbide substrate with an optimised chipformer to promote secure chip control and reduced edge degradation. This results in more consistent cycle times and fewer interruptions for edge changes. The rhombic 55° shape and the modest 0.4 mm corner radius balance edge strength with the capability to achieve good surface finishes in medium-duty turning operations.

Coating and grade that support repeatable results

The multilayer Tiger·tec Silver coating enhances thermal resistance and reduces adhesive wear when cutting austenitic and other stainless steels. Compared with uncoated grades, this coating improves tool life under interrupted cuts and higher cutting temperatures. The WMP20S carbide grade is tuned specifically for the M material group, so it supports stable chip formation and predictable wear behaviour, which simplifies process qualification and reduces scrap rates during production runs.

Geometry and chip control that reduce downtime

The insert’s MM5 chipbreaker is designed to produce short, controllable chips across a range of cutting depths and feeds commonly used in shop-floor turning. The rhombic 55° form provides secure seat engagement in standard toolholders and enables versatile approach angles for both light finishing and heavier turning passes. The 0° negative rake increases cutting-edge stability, helping to avoid chatter and maintain dimensional consistency on shafts and bores. Together, these features promote longer tool life and fewer insert indexings per batch.

Practical integration and measurable benefits

Installation is straightforward in holders compatible with DNMG-format inserts; the flat seating face and secure clamping ensure repeatable positioning. Using this insert in a structured production setting typically yields benefits in process reliability: lower rework rates thanks to stable edge condition, and extended intervals between indexings. For production planners the controlled performance of the WMP20S grade supports reliable cycle-time estimates and predictable tool-change schedules, which aids capacity planning and cost accounting.

FAQ

Is this insert suitable for stainless-steel turning? Yes. The DNMG150604-MM5 WMP20S insert is specifically designed for machining stainless steels and the WMP20S grade supports secure chip formation and heat resistance.

What advantages does the Tiger·tec Silver coating offer? The Tiger·tec Silver coating on the WMP20S grade improves thermal stability and reduces adhesive wear, resulting in longer tool life and more consistent edges when cutting stainless steel.

Which chipbreaker is fitted and what is its effect? The insert uses an MM5 chipbreaker, which produces short, controllable chips across common feeds and depths, reducing the risk of entanglement and improving process reliability.

Can the insert be used for finishing passes? Yes. With its rhombic 55° form and 0.4 mm corner radius, the insert can achieve good surface quality on finishing passes while retaining sufficient edge strength for medium-duty work.

What does the 0° negative rake mean for machining? A 0° negative rake increases edge robustness and reduces the tendency to vibrate under heavier cuts, improving dimensional stability in turning operations.
