WNMG080408-RP5 WPP20G turning insert, Trigon 80°, Tiger·tec Gold for steel – Walter Tools

The WNMG080408-RP5 WPP20G is a Trigon 80° negative-insert designed for productive steel turning, combining a wear-resistant Tiger·tec Gold coating with an RP5 chipbreaker for stable chip formation.

• Tiger·tec Gold coated carbide grade WPP20G
• Optimised RP5 chipbreaker for steel applications
• Trigon 80° form for rigid clamping and stability
• 0.8 mm corner radius for improved surface finish

Consistent productivity through advanced grade and coating

The Tiger·tec Gold WPP20G grade provides a balanced combination of wear resistance and toughness specifically tailored for steel (ISO P) machining. This results in predictable tool life and reduced process variation, which supports higher machine uptime and consistent part quality. The coated carbide layer improves thermal stability and reduces flank wear, enabling longer cutting intervals and fewer insert changes. For operations where repeatable performance and reduced tooling costs matter, this grade delivers measurable benefits.

Reliable chip control for safer, faster turning

The integrated RP5 chipbreaker is optimised for common steel turning tasks, promoting controlled chip formation under a wide range of cutting conditions. Stable chips reduce the risk of surface damage and shorten cycle times because interrupted feed or rework is minimised. The combination of chipbreaker geometry and the Tiger·tec Gold coating improves metal flow at the cutting edge, which is particularly advantageous in medium to heavy roughing where consistent evacuation of swarf is critical for operator safety and machine protection.

Geometry and seat design that enhance accuracy and clamping security

The Trigon 80° insert form, with a 0.8 mm corner radius and a negative 0° relief angle, provides a secure clamping situation and robust cutting edge support. The geometry is especially suitable for turning operations that demand rigidity and repeatable concentricity. A modest corner radius like 0.8 mm helps to deliver improved surface finish without sacrificing edge strength, making the insert well suited for both semi-finishing and finishing passes in steel. This design reduces vibration and supports dimensional stability on conventional and CNC lathes.
