DNMG110408-MM5 WMP20G indexable turning insert — Tiger‑tec Gold, for stainless‑steel machining | Walter Tools

The DNMG110408-MM5 WMP20G is a robust indexable turning insert designed for medium to heavy machining of stainless steel, combining a coated carbide grade with a dedicated chipbreaker for stable performance.

• Tiger‑tec Gold coated grade WMP20G
• Optimised MM5 chipbreaker for stable chips
• Rhombic 55° geometry for versatile turning
• 0.8 mm corner radius, 0° negative rake

Reliable performance for stainless‑steel turning

The Tiger‑tec Gold WMP20G grade is tailored for the specific demands of stainless steel: high toughness, a tendency to build up on the cutting edge and elevated thermal loads. The coated carbide composition provides a stable cutting edge under such conditions, reducing the risk of built‑up edge and enabling longer intervals between index changes. Choosing a coated grade designed for this material group improves process stability and helps maintain consistent component tolerances in serial production.

Predictable chip control and surface finish

The MM5 chipbreaker is optimised to produce short, controllable chips when machining ductile, work‑hardening grades. In combination with the rhombic 55° shape and a 0.8 mm corner radius, the geometry balances edge strength with the ability to achieve a good surface finish. The 0° (negative) rake increases the robustness of the cutting edge, making the insert suitable for interrupted cuts and harder stainless grades while supporting reliable chip evacuation and reduced rework.

Efficient integration and repeatable tool life

As an indexable insert with a standard ISO designation, this component is straightforward to seat in common toolholders and insert pockets, allowing fast changeovers and predictable set‑up times. The coated grade and geometry aim to deliver repeatable cutting performance and extended edge life, which contributes to higher overall productivity and reduced tooling costs per part. For production environments seeking consistent throughput, the insert supports stable process windows and fewer unscheduled interventions.

FAQ

Which materials is this insert intended for?
The DNMG110408-MM5 WMP20G is formulated for stainless steel machining (ISO group M) and performs best under moderate to robust cutting conditions.

What benefit does the MM5 chipbreaker provide?
The MM5 chipbreaker promotes short, controllable chips and stabilises chip formation when machining ductile stainless‑steel grades, supporting consistent surface quality.

How does the 0° negative rake affect cutting?
A 0° (negative) rake increases edge strength and resistance to chipping, which is beneficial for interrupted cuts and tougher stainless‑steel alloys when using this turning insert.

Can this insert be used in standard toolholders?
Yes — the insert follows ISO indexable insert conventions and fits compatible DNMG toolholders, enabling quick replacement and consistent positioning.

What does the Tiger‑tec Gold series contribute?
The Tiger‑tec Gold coating enhances wear resistance and thermal stability of the cutting edge, extending useful edge life during stainless‑steel turning operations.
