DNMG150408-MM5 WMP20S indexable turning insert for stainless steel — Walter Tools

The DNMG150408-MM5 WMP20S is an indexable turning insert engineered for reliable machining of rostfreier Stahl, combining a Tiger·tec Silver coating with an MM5 chipbreaker for consistent chip control and surface quality.

• Tiger·tec Silver coating for wear resistance
• MM5 chipbreaker for controlled chip formation
• 0° negative rake for robust cutting
• Optimised for rostfreier Stahl machining

Precision and wear resistance for demanding stainless steel turning

The coated carbide grade from the Tiger·tec Silver family delivers enhanced wear resistance and improved thermochemical stability in the face of stainless steel’s tendency to work-harden and generate heat. Thanks to the tailored coating and substrate combination, the insert sustains a stable cutting edge under medium to heavy cutting conditions, which supports longer tool life and fewer interruptions for tool change. The described combination reduces flank wear and helps maintain dimensional stability over longer production runs, increasing process reliability and productivity.

Controlled chips and consistent surface finish

Integrated MM5 chipbreaking geometry is designed to fragment and evacuate chips efficiently during turning of rostfreier Stahl, lowering the risk of built-up edge and uneven surfaces. The insert’s corner radius 0.8 mm balances edge strength with the ability to achieve good surface quality on turned components. The combination of chip control and corner geometry contributes to predictable results in automated and semi-automated turning operations, improving cycle times and reducing rework.

Robust geometry that supports stable cutting conditions

A 0° (negative) rake angle and the rhombic 55° insert form deliver mechanical robustness in interrupted cuts and heavier cross-sections. The insert’s geometry, together with the coated grade, enables secure cutting under varied feed and depth-of-cut settings, making the solution suitable for general stainless-steel turning where edge stability is a priority. Clear labelling and ISO designation facilitate quick tool selection and repeatability in production environments.

Application advice and integration into production

This indexable solution is particularly suited to applications where rostfreier Stahl is the primary material group and where process security and repeatable surface integrity matter. For initial parameter selection, moderate cutting speeds with adequate coolant or appropriate lubrication help to control temperatures and support chip control. The insert works well in standard tool holders compatible with the DNMG form and benefits from consistent clamp and seat conditions to exploit the full potential of the Tiger·tec Silver coating.

FAQ

What materials is this insert intended for?
The DNMG150408-MM5 WMP20S insert is designed specifically for machining rostfreier Stahl and is optimised for the challenges of stainless-steel turning.

How does the MM5 chipbreaker improve performance?
The MM5 chipbreaker on the WMP20S grade promotes controlled chip fragmentation and evacuation, which reduces built-up edge and supports a consistent surface finish during stainless-steel turning.

Can the insert be used for heavy interrupted cuts?
Yes. The 0° negative rake and robust rhombus 55° geometry provide mechanical strength suitable for interrupted cuts and demanding turning conditions when using the DNMG150408-MM5 WMP20S insert.

Which series provides the coating and substrate properties?
The insert belongs to the Tiger·tec Silver series; this coating and substrate combination enhances wear resistance and thermal stability during turning of rostfreier Stahl.
