WNMG060408-RM5 WMP20G indexable turning insert – Trigon 80°, Tiger‑tec Gold for stainless steel | Walter Tools

The WNMG060408-RM5 WMP20G is a Trigon 80° indexable insert engineered for dependable machining of stainless steel in medium to robust cutting conditions

• Tiger‑tec Gold coating for stable cutting performance
• Optimised RM5 chipbreaker for reliable chip control
• Trigon 80° geometry with 0.8 mm corner radius
• Designed for stainless steel (ISO M) machining

High process reliability for stainless steel machining

The WNMG060408-RM5 WMP20G insert is based on the Tiger‑tec Gold technology, a coated carbide solution developed to address the specific challenges of stainless steel (ISO M). The composition and coating promote stable cutting edges and reduce the tendency for built‑up edge formation, which in turn lowers rework rates and improves cycle consistency. For production environments that require predictable tool life and steady surface quality, this grade offers a clear advantage by supporting continuous, productive machining under medium to robust conditions.

Geometry that increases edge strength and productivity

The Trigon 80° shape combined with a 0.8 mm corner radius and a negative 0° rake provides mechanical strength at the cutting edge and stability in interrupted or heavy cuts. This geometry reduces stress concentrations and supports higher feed rates without sacrificing finish quality. The insert thickness and standardised form ensure compatibility with common holders, simplifying tool management and enabling quick index changes to maintain uptime and throughput.

Controlled chips and improved surface finish

The RM5 chipbreaker is optimised to produce compact, controllable chips during turning of tough, ductile alloys like austenitic stainless steels. Effective chip control reduces the risk of chip entanglement and minimises manual clearing, which contributes to a safer, more efficient shopfloor. At the same time, the combined effect of the coating and chipbreaker assists in achieving a consistent surface condition, reducing downstream polishing or grinding operations.

Practical integration and application benefits

As an indexable turning insert, this grade is suitable for a wide range of workshop applications where processing stainless steel is routine. The WMP20G grade delivers a balance of wear resistance and edge toughness, making it practical for batch production and jobbing alike. Stocking this insert supports flexible machining strategies and cost‑effective tooling cycles, while its standardised designation facilitates quick ordering and inventory control.
