DNMG150612-MM5 WMP20S Indexable Turning Insert — for Stainless Steel | Walter Tools

A DNMG150612-MM5 WMP20S indexable turning insert engineered for reliable, medium-to-robust machining of stainless steels in general turning applications

• Tiger‑tec Silver coating for stainless steel machining
• Stable cutting edge with MM5 chipbreaker
• Rhombic 55° geometry for versatile turning
• 0° negative rake and 1.2 mm corner radius

Increase throughput with a high-performance grade

The combination of the Tiger‑tec Silver series and the WMP20S grade provides a coated carbide solution tailored to the challenges of machining stainless steel. The coating technology promotes secure chip formation and a robust cutting edge, which translates into higher cutting speeds and longer intervals between indexings. For production planners and shop floor managers this means fewer tool changes, more predictable cycle times and improved component consistency under medium to heavy cutting conditions.

Geometry that balances versatility and surface integrity

A rhombic 55° insert form with 0° negative rake delivers a versatile cutting geometry suitable for a wide range of turning tasks. The 1.2 mm corner radius supports moderate stock removal while protecting the edge from thermal and mechanical loading, helping to maintain surface finish and dimensional stability. This geometry is particularly useful where both roughing and semi-finishing passes are required with the same insert type, reducing tool inventory and set‑up complexity.

Effective chip control and process reliability

Equipped with the MM5 chipbreaker, this insert is designed to manage the chip behaviour typical of the ISO M group. Stable chips and controlled evacuation reduce the risk of chip re-cutting and built-up edge formation, improving reproducibility across serial production. The indexable insert format simplifies reconditioning strategies: predictable wear patterns enable more efficient tool-change scheduling and downstream process planning, supporting continuous, traceable manufacturing performance.

Practical guidance for integration and cost efficiency

When implemented in a matched clamping system and paired with suitable cutting data for stainless steel, the grade delivers notable life and consistent results. Operators benefit from the insert’s resistance to edge degradation in sticky, heat‑prone materials, which lowers total tooling costs per part over time.

FAQ

What materials is this insert best suited for?
The DNMG150612-MM5 WMP20S grade is optimised for stainless steel (ISO M); the Tiger‑tec Silver coating and MM5 chipbreaker support secure chip formation and edge stability in these materials.

How does the MM5 chipbreaker influence performance?
The MM5 chipbreaker promotes predictable chip shapes and evacuation, reducing the likelihood of built‑up edge and re‑cutting, which helps to maintain surface quality and tool life during serial turning operations.

Can this insert be used for both roughing and finishing?
Yes, the rhombic 55° geometry with a 1.2 mm corner radius provides a balance between strength and finish capability, making the insert suitable for combined roughing and semi‑finishing tasks in many setups.

Where to obtain cutting data and tooling recommendations?
Metav Werkzeuge can supply application‑specific cutting parameters and holder compatibility advice for the DNMG150612-MM5 WMP20S insert to help optimise process reliability and part quality.
