WNMG080412-MW5 WPP20G – Indexable turning insert, Trigon 80°, Tiger·tec Gold (Walter Tools)

The WNMG080412-MW5 WPP20G is an indexable turning insert designed for steel machining; it pairs a Tiger·tec Gold coated carbide grade with a robust MW5 chipbreaker and trigon 80° geometry to deliver productive, repeatable results in industrial turning applications.

• Tiger·tec Gold coated carbide grade WPP20G
• Optimised MW5 chipbreaker for steel
• Trigon 80° insert with 1.2 mm corner radius
• 0° negative rake for robust cutting

Productive steel machining with a coated carbide grade

The combination of the WPP20G coating technology and a wear-resistant carbide substrate provides a balance of toughness and wear resistance tailored for machining steel (ISO group P). The coated structure reduces flank wear and improves tool life under the heat and chip loads typical of steel turning. As a consequence, cycle times are more consistent and component tolerances remain stable — an important factor when process reliability and throughput matter in production environments. The Tiger·tec Gold designation signifies proven coating performance for universal steel applications.

Geometry engineered for stability and chip control

A Trigon 80° form with a 1.2 mm corner radius offers increased edge strength for interrupted cuts and heavier engagements. The MW5 chipbreaker is optimised for typical steel chip formation, promoting short, controllable chips that evacuate reliably and reduce the risk of workpiece damage or tool interference. The 0° negative rake contributes to a robust cutting edge, making the insert suitable for operations where rigidity and resistance to edge chipping are priorities.

Specification clarity for process planning

Key designations such as the WNMG shape code and the WPP20G grade provide clear guidance for tool selection and replacement. The insert’s size and thickness codes allow simple matching with toolholders and adapters according to established ISO conventions. Using this standardised nomenclature streamlines inventory management in the tool crib and ensures compatibility across toolholder families. The tolerance class M indicates manufacturing precision appropriate for industrial turning tasks.

Application benefits and workshop integration

Integrating this indexable insert into production processes typically results in lower per-part tool costs thanks to the coated carbide’s extended life and the multi-edge usability of the insert form. The MW5 chip control reduces secondary operations and cleanup, improving overall process efficiency. For shops seeking a balance between productivity and reliability, this insert supports consistent finishes and repeatability across batch runs while remaining easy to replace and index when required.
