WNMG080412-RP7 WPP20G – Indexable turning insert, Tiger‑tec Gold, Trigon 80° (Walter Tools)

A WNMG080412-RP7 WPP20G indexable turning insert engineered for machining steel, featuring a Trigon 80° form and an RP7 chipbreaker for controlled chip formation.

• Tiger·tec Gold coating for extended tool life
• RP7 chipbreaker optimised for steel chips
• Trigon 80° form for versatile turning
• Corner radius 1.2 mm for robust edge strength

Consistent performance and extended tool life through coating technology

The combination of the Tiger‑tec Gold coating and the WPP20G grade provides a marked improvement in wear resistance during steel turning operations. The coated cemented carbide construction reduces flank and crater wear under typical cutting temperatures, which translates into longer cutting intervals and fewer index changes. This contributes to a steadier production flow and lower tooling-related downtime, delivering measurable gains in process efficiency for batch and continuous turning tasks.

Predictable chip control and stable cutting behaviour

The RP7 chipbreaker, paired with the Trigon 80° geometry and a 0° (negative) rake angle, is designed to produce short, consistent chips when machining steel. The corner radius 1.2 mm increases edge strength and resistance to mechanical shock, improving stability in interrupted cuts and heavier engagement scenarios. Together these features enable more predictable tool life and help maintain surface finish quality, supporting efficient spindle utilisation on CNC turning centres.

Universal applicability and easy integration into turning setups

Classified for steel (ISO group P), the insert offers a balance between toughness and wear resistance suited to a wide range of turning applications. The WNMG form factor and the size/thickness codes make the insert compatible with standard WNMG toolholders, allowing straightforward replacement and inventory management. The tolerance class M ensures consistent fit and repeatability at tool changes, supporting reproducible results across multiple machines and operators.
