WNMG080412-RP5 WPP20G Turning insert — Tiger‑tec Gold, for steel, Walter Tools

WNMG080412-RP5 WPP20G is a coated carbide turning insert designed for productive steel machining with a Trigon 80° geometry and RP5 chip control

• Tiger‑tec Gold coated carbide
• Trigon 80° insert geometry
• RP5 chipbreaker for steel
• 1.2 mm corner radius for stability

Reliable cutting performance through advanced coating and substrate

The combination of the Tiger‑tec Gold coating and a coated carbide substrate provides a balance between wear resistance and fracture toughness. This results in improved process stability when machining unalloyed and alloyed steel under typical heat and chip formation conditions. The coated surface reduces flank wear and helps to maintain a consistent cutting edge, which in turn supports longer tool life and fewer insert changes — a tangible efficiency gain on production lines where uptime and repeatability matter.

Geometry that enhances stability and repeatable accuracy

The Trigon 80° form delivers a favourable approach angle for a wide range of turning operations, while the 1.2 mm corner radius increases edge strength for interrupted cuts and roughing passes. The 0° relief (negative) design contributes to rigidity and reduces vibration in heavier cuts, making the geometry particularly suitable where dimensional fidelity and surface consistency are required. These geometric choices translate into steadier chip loads and a reduced risk of edge chipping, supporting predictable tool behaviour across batches.

Controlled chip formation and cost‑efficient productivity

The RP5 chipbreaker is engineered for effective chip control in the ISO P (steel) group, promoting short, easily evacuable chips under a variety of cutting conditions. Improved chip control lowers machine downtime due to chip-related issues and reduces manual handling or secondary operations for chip clearing. Together with the coated carbide grade, this chipbreaker contributes to a favourable cost‑per‑component ratio by enabling higher cutting parameters where appropriate and by stabilising tool life across mixed steel lots.

Application scope and process guidance for seamless integration

Classified for the ISO P group, the insert is suitable for a broad spectrum of steel turning tasks, from general turning to more demanding roughing operations where wear resistance and edge robustness are essential. The plate identification indicates a universal toughened grade within the Tiger‑tec Gold family, optimised for reliable chip formation and consistent surface finish. For new setups, a stepwise increase of cutting speed and feed while monitoring surface finish and tool wear will help determine the most productive window for any specific steel grade or machine setup.
