DCMT11T302-MM4 WMP20G — Indexable turning insert, Tiger·tec Gold, for stainless steels (Walter Tools)

The DCMT11T302-MM4 WMP20G is an indexable turning insert engineered for medium to robust machining of stainless steels, optimising chip control and tool life in demanding turning operations.

• Tiger·tec Gold coating for improved tool life
• Optimised MM4 chipbreaker for stable chip control
• 7° clearance angle for secure cutting action
• 0.2 mm corner radius for precise finishing

Consistent cutting performance for stainless steels

The coated carbide grade delivers a reliable balance between wear resistance and toughness. Thanks to the Tiger·tec Gold technology and the WMP20G substrate, the insert maintains a stable cutting edge under the thermal and adhesive tendencies typical of stainless steels, reducing the risk of built-up edge. The combination of a dedicated MM4 chipbreaker and the specified geometry produces predictable chip forms, which contributes directly to improved cycle times and reduced secondary operations.

Better surface quality through controlled geometry

A 0.2 mm corner radius and a rhombic 55° form support fine finishing while providing sufficient edge strength for mid-range cutting depths. The 7° clearance provides consistent engagement and reduces rubbing, which lowers heat generation at the cutting zone and helps achieve a superior surface finish. For workshops aiming to balance productivity and part quality, the insert’s geometry enables both repeatable dimensional accuracy and reduced rework.

Productivity gains from predictable tool life

Using a coated grade in the Tiger·tec Gold family means longer effective cutting time before regrinding or indexing is required. The WMP20G composition, combined with the insert’s MM4 chip management, helps maintain cutting performance across a range of feeds and speeds typical for machining rust‑resistant alloys. This predictability supports planning for tool change intervals and machining throughput, improving process reliability on series and job‑shop orders.

Practical application and selection guidance

The insert is optimised for applications in which stainless steels are the primary material group; the specification supports both medium turning and finishing operations. When selecting cutting parameters, favour stable feeds with moderate cutting speeds to exploit the coating’s heat resistance and the chipbreaker’s efficiency.
