WNMG060408-MW5 WPP20G turning insert – Trigon 80°, Tiger‑tec Gold (Walter Tools)

The WNMG060408-MW5 WPP20G is a negative‑rake, trigon indexable turning insert optimised for efficient machining of steel components.

• Tiger‑tec Gold coating for extended tool life
• Trigon 80° geometry for stable turning
• 0.8 mm corner radius for robust edge strength
• Optimised MW5 chipbreaker for steel machining

Maximise throughput and lower cost per part with a coated grade built for steel

The coated‑carbide grade WPP20G, based on the Tiger‑tec Gold technology, is designed to balance wear resistance and toughness when machining steel. The coating reduces flank wear and improves resistance to built‑up edge, which directly extends tool life and reduces tool‑change frequency. For production environments seeking predictable output, this combination supports a lower cost per finished component while maintaining surface quality and repeatability.

Stable machining thanks to engineered chip control and geometry

The MW5 chipbreaker is developed for consistent chip formation when working typical steel alloys (ISO group P). By promoting short, segmented chips and reliable evacuation, the chipbreaker reduces the risk of chatter and tool interference with the workpiece. The negative 0° relief and the insert’s geometry contribute to process stability, especially in interrupted cuts or heavy roughing passes, improving cycle time without compromising safety.

Robust edge and form for demanding turning tasks

The Trigon 80° insert shape provides a rigid support base in the toolholder, enabling higher feed and depth‑of‑cut capability compared with more acute geometries. The 0.8 mm corner radius offers a compromise between strength and finishing capability: the edge resists edge chipping under higher loads while still permitting satisfactory surface finish when used in finishing passes. The insert’s tolerance class M implies consistent dimensional accuracy for secure clamping and repeatable installation.

Application scope and handling recommendations for workshop use

Marked for ISO group P (steel), this insert is suitable for unalloyed and alloyed steels where a balance of wear resistance and toughness is required. The combination of coated carbide substrate and the Tiger‑tec Gold coating means it is especially effective in general turning, shoulder work and medium to heavy roughing where chip control and tool life are priorities. For best results, pair the insert with a suitable WNMG toolholder and verify seat and clamp condition to ensure stable support and correct rake alignment.

FAQ

What steels is this insert suited for?
The WNMG060408‑MW5 WPP20G insert is formulated for ISO group P materials; the WPP20G grade and Tiger‑tec Gold coating provide wear resistance and toughness appropriate for unalloyed and alloyed steels.

Can the insert handle interrupted cuts or roughing passes?
Yes. The negative relief (0°) and the 0.8 mm corner radius, together with the Trigon 80° form, give the insert robust edge support and stability for interrupted cuts and heavier roughing operations.

Which chip behaviour can be expected with the MW5 chipbreaker?
The MW5 chipbreaker on this insert promotes short, controlled chips during turning of steels, improving evacuation and reducing the likelihood of entanglement or workpiece damage.

Is this insert suitable for finishing to a high surface quality?
The insert can achieve good surface finishes when used with appropriate feeds and speeds; however, the emphasised strength and chip control make it particularly advantageous for productive roughing and semi‑finishing in steel turning.
