WNMG080412-MP3 WPP20G Drehwendeschneidplatte – Trigon 80° (Tiger·tec Gold) by Walter Tools

The WNMG080412-MP3 WPP20G is a negative Trigon 80° turning insert designed for efficient machining of steel in general turning applications.

• Tiger·tec Gold coated grade WPP20G
• Optimised MP3 chipbreaker for continuous cuts
• Trigon 80° insert with 1.2 mm corner radius
• Negative 0° rake for stable turning
• Designed for steel machining (ISO group P)

Greater wear resistance and reliable steel machining

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers pronounced wear resistance and dependable performance when machining steels. The grade is engineered for the thermal and chip-formation characteristics typical of steel (ISO group P, see ISO 513) and provides a balanced compromise between hardness and toughness. For production environments this means fewer insert changes and more predictable tool-life, supporting stable cycle times and consistent part quality.

Stable cutting geometry for improved surface finish

A Trigon 80° geometry with a 1.2 mm corner radius and a 0° rake (negative) offers strong edge support and vibration resistance in conventional turning operations. The MP3 chipbreaker is optimised for continuous and medium feeds, promoting controlled chip flow and reducing the risk of built-up edge. The result is a measurable improvement in surface finish and dimensional stability, with the insert geometry helping to maintain accuracy in longer runs and reducing the need for subsequent finishing passes.

Productivity advantages for series and workshop turning

Manufactured by Walter Tools within the Tiger·tec Gold family, this insert balances economy and process security for small to medium batch production. The grade tolerates standard machining conditions for unalloyed and alloyed steels, enabling consistent cutting performance across a broad range of workpiece grades. With its MP3 chip control and robust negative geometry, the insert reduces downtime associated with edge failures and supports a more predictable production flow, making it suitable for operations seeking repeatable results and improved throughput.
