WNMG080408-RP7 WPP30G indexable turning insert (Trigon 80°, Tiger·tec Gold) — Walter Tools

The WNMG080408-RP7 WPP30G is an indexable turning insert engineered for steel machining, offering a Tiger·tec Gold coated grade and a robust Trigon 80° geometry for general-purpose and medium-duty turning.

Tiger·tec Gold coated grade WPP30G
Trigon 80° insert geometry
0.8 mm corner radius for edge strength
Suitable for steel (ISO P) machining

High wear resistance and consistent life for steel turning

The combination of the WPP30G grade and Tiger·tec Gold technology delivers enhanced wear resistance and improved thermal stability when machining steels (ISO P). The coated cemented carbide microstructure is optimised for the heat and chip conditions typical of steel turning, which supports stable chip formation and predictable tool life. This reliability reduces unplanned tool changes and stabilises cycle times in batch and continuous production.

Geometry designed to secure cutting edges and surface quality

The Trigon 80° form with a corner radius of 0.8 mm and negative rake (0°) provides a mechanically strong cutting edge that resists chipping during interrupted cuts and heavier feed conditions. The angular geometry contributes to vibration damping and consistent contact conditions, which can improve surface finish and extend edge life. Specifying this insert supports machining strategies where edge stability and repeatability are priorities.

Process reliability and adaptable chip control

Equipped with the RP7 chipbreaker, the insert supports reliable chip control across a range of steel grades, making it suitable for both finishing and more demanding semi‑finishing tasks. The tolerance class M assures dimensional consistency for repeatable clamping and predictable performance. Overall, the insert’s design reduces downtime associated with chip-related issues and simplifies process setup for mixed steel applications.

FAQ

What steels is this insert suitable for?
The WNMG080408-RP7 WPP30G is formulated for ISO P materials, covering unalloyed and alloyed steels where thermal load and typical steel chip formation occur.

How does the Tiger·tec Gold coating benefit machining?
Tiger·tec Gold enhances wear resistance and thermal stability on the insert, which improves tool life and process consistency when turning steel with the Walter Tools insert.

Is the RP7 chipbreaker appropriate for finishing operations?
Yes, the RP7 chipbreaker is designed to provide controlled chip formation for both finishing and medium-depth cuts, contributing to stable surface quality.

Why choose a negative rake (0°) geometry for this insert?
A negative rake increases edge robustness and reduces the tendency to chip under interrupted cuts or heavy feeds, resulting in more predictable performance in demanding turning tasks.

What does the tolerance class M indicate for this insert?
Tolerance class M denotes standard dimensional consistency suitable for reliable clamping and repeatable positioning in toolholders and turret systems.
