WNMG080408-RP7 WPP20G — Trigon 80° indexable turning insert, Tiger‑tec Gold by Walter Tools

The WNMG080408-RP7 WPP20G is a trigon, 80° turning insert intended for versatile steel machining where secure chip formation and extended edge life are required.

• Tiger‑tec Gold coated carbide
• Optimised RP7 chipbreaker
• 0° negative rake for stable cutting
• 0.8 mm corner radius for durable edge

Consistent productivity through proven coating technology

The Tiger‑tec Gold coating delivers a combination of hardness and oxidation resistance that is designed to extend tool life under the thermal loads typical of steel machining. Because coated carbide reduces flank wear and resists built-up edge, the result is fewer interruptions for insert changes and more predictable cycle times. This stability is particularly valuable in batch production and in setups where reproducible performance is a priority, as the insert's behaviour is easier to predict and integrate into machining process planning.

Better chip control and surface quality with a tailored chipbreaker

The RP7 chipbreaker is engineered to create short, manageable chips when machining steels in the ISO P range. Improved chip formation reduces the risk of chip entanglement and helps maintain tool clearance, which in turn supports a consistent surface finish and lowers the chance of part rework. For operators less familiar with chipbreaker design: the chip geometry actively controls chip curl and breakage, turning potentially hazardous long chips into compact segments that are easier to evacuate from the cutting zone.

Geometry and edge preparation for robust turning performance

The trigon 80° shape provides a positive combination of strength and accessibility to the cutting edge, while the 0.8 mm corner radius balances edge durability with the ability to produce acceptable radii on workpieces. The 0° negative rake configuration gives a stronger cutting edge for interrupted cuts and heavy roughing passes, promoting process reliability under higher mechanical loads. These geometric choices make the insert suitable for a wide range of steel grades as indicated by ISO P, delivering repeatable results across varied production tasks.

Practical advantages for workshop integration

Identification and handling are simplified by the standard WNMG designation and the clear grade marking WPP20G, enabling quick tool selection in toolrooms and automatic tool changers. The insert's coded dimensions and chipbreaker type align with common toolholder systems, minimising compatibility checks and speeding tool changes. If further process data or cutting parameters are required for integration into an existing workflow, Metav Werkzeuge’s application support can supply recommended speeds, feeds and edge treatment notes to suit the specific machine and workpiece material.

FAQ

What materials is this insert suitable for?
The WNMG080408-RP7 WPP20G is formulated for machining steels (ISO P), with the Tiger‑tec Gold coating and RP7 chipbreaker optimised for typical steel heat and chip-forming behaviour.

How does the RP7 chipbreaker improve machining?
The RP7 chipbreaker on this Walter Tools insert produces compact chips that are easier to evacuate, reducing entanglement and improving surface consistency during turning operations.

Is this geometry suitable for interrupted cuts or heavy roughing?
Yes, the trigon 80° form with a 0° negative rake provides a robust cutting edge that enhances stability for interrupted cuts and heavier roughing passes.

Can the insert be used for finishing operations?
While primarily suited to roughing and semi-finishing, the 0.8 mm corner radius permits acceptable finishes; for high-precision finishing, finer radii or dedicated grades may be preferable.

How is the grade WPP20G positioned in terms of wear and toughness?
WPP20G, in Walter Tools' Tiger‑tec Gold family, offers a balanced combination of wear resistance and toughness tailored for reliable performance across a broad range of steel grades.
