WNMG080404-MP3 WPP20G turning indexable insert – Trigon 80°, Tiger‑tec Gold by Walter Tools

The WNMG080404-MP3 WPP20G is a trigon 80° turning insert designed for industrial steel machining, combining a high-performance coated carbide grade with a chipbreaker tuned for reliable chip formation.

• Tiger‑tec Gold coated carbide
• Optimised for steel (P) machining
• Trigon 80° geometry for stable cuts
• MP3 chipbreaker for reliable chip control

High-performance coating for longer productive runs

The Tiger‑tec Gold coating paired with the WPP20G grade provides a corrosion-resistant, wear-resistant surface layer that improves cutting-edge stability during prolonged operations. This coated carbide grade is formulated for the thermal and mechanical demands of machining steel, reducing flank wear and helping to maintain dimensional accuracy over longer cycles. The result is measurable economy through fewer indexings and predictable tool life under typical turning conditions.

Geometry engineered for process stability and accuracy

The Trigon 80° form and the 0° negative rake geometry create a robust cutting edge that resists chipping and vibration. A 0.4 mm corner radius supports stronger edges for interrupted cuts and roughing passes, while the trigon shape provides three cutting corners per insert for efficient utilisation. These design elements combine to improve process reliability, reduce the likelihood of unplanned tool changes and support stable surface finish results even in heavier cut regimes.

Chip control that maintains surface quality and throughput

The MP3 chipbreaker is tuned to the alloy-class behaviour of steel (ISO group P), promoting segmented, short chips that evacuate predictably. Controlled chip formation lowers the risk of entanglement and reduces machine downtime due to chip-related issues. Consistent chip flow contributes to repeatable surface integrity and reduces secondary finishing effort, supporting higher throughput in batch production and single-piece flow alike.

Practical application notes for shop-floor integration

This insert is intended for general turning operations in unalloyed and alloyed steel applications where consistent tool life and edge stability matter. The insert's format (size 08, thickness 04) and the MP3 chipbreaker make it suitable for a range of feed and depth-of-cut combinations; experiments on the specific machine/toolholder combination should be conducted to optimise cutting parameters. For mixed operation environments, the coated carbide and trigon form provide a reliable compromise between durability and versatility.

FAQ

What materials is this insert intended for? The WNMG080404-MP3 WPP20G insert is designed primarily for steel (ISO group P) machining and performs well across unalloyed and alloyed steels.

How does the Tiger‑tec Gold coating benefit machining? The Tiger‑tec Gold coating on the WPP20G grade increases wear resistance and edge stability, which helps to extend tool life and maintain consistent dimensional results during production.

What advantages does the Trigon 80° shape provide? Trigon 80° geometry offers a stronger cutting edge and three usable corners per insert, improving stability for heavier cuts and interrupted operations while supporting efficient tool utilisation.

Is the MP3 chipbreaker suitable for finishing passes? The MP3 chipbreaker manages chip formation reliably; in many setups it provides a balanced performance for both medium finishing and general-purpose turning, though parameter tuning is recommended for fine-finishing requirements.

Can this insert be used for interrupted cuts or tough conditions? Yes, the combination of Trigon 80°, 0.4 mm corner radius and the WPP20G grade increases resistance to edge chipping, making the insert suitable for interrupted cuts and demanding steel applications.
