TNMG220412-RM5 WMP20G — Indexable turning insert, Tiger·tec Gold, for rostfreier Stahl (Walter Tools)

The TNMG220412-RM5 WMP20G is a triangular 60° indexable turning insert with an RM5 chipbreaker, designed for medium to robust machining of rostfreier Stahl and for stable edge performance.

• Tiger·tec Gold coated grade WMP20G
• Optimised chip control with RM5 breaker
• Triangular 60° form, 1.2 mm nose radius
• Suited for rostfreier Stahl machining

Consistent cutting performance for rostfreier Stahl

The combination of the WMP20G grade with Tiger·tec Gold coating provides a balance between wear resistance and edge toughness that is particularly advantageous for rostfreier Stahl. The coating technology supports controlled friction and heat management at the cutting zone, which promotes stable chip formation and reduces the tendency for built-up edge. Thanks to the RM5 chipbreaker, chips are segmented and discharged reliably, improving process repeatability and lowering the risk of unexpected stoppages. This technical blend translates directly into fewer scrap parts and steadier cycle times on production lines.

Improved productivity through stable edges and predictable life

A coated cemented-carbide grade that emphasises edge stability increases usable tool life and helps maintain part tolerances over longer runs. The insert’s design—a negative 0° relief for robust engagement—enables secure cutting in heavier cuts and interrupted operations without compromising the cutting edge. The result is a measurable uplift in throughput and reduced frequency of insert changes, which supports leaner tool inventories and more efficient shift planning. These characteristics are particularly valuable in high-mix environments where process security is critical.

Practical geometry for versatile workshop use

The triangular 60° form offers several indexed cutting corners, making the insert cost-effective in daily shop use. The 1.2 mm nose radius smooths surface finish and helps resist edge chipping under variable conditions, while the RM5 chipbreaker is tuned for medium to sturdy cutting parameters. Together, these design elements facilitate straightforward integration into standard turning toolholders and make the insert appropriate for both job-shop and serial production contexts. For customers seeking application guidance, Metav Werkzeuge can advise on holder selection and cutting data.

Clear material match and selection guidance

Classified for ISO group M, this insert is optimised for rostfreier Stahl, which typically requires tools that manage heat and plastic deformation at the cutting edge. The coated grade and chipbreaker reduce the common issues of adhesion and thermal softening, so finishing quality and dimensional stability are easier to maintain. Selecting the TNMG220412-RM5 WMP20G supports a predictable process window and helps ensure repeatable surface integrity across batches, contributing to overall process reliability and component consistency.
