TNMG270616-RP7 WPP20G – Indexable turning insert, Tiger·tec Gold coating, for Stahl | Walter Tools

The TNMG270616-RP7 WPP20G is an indexable turning insert intended for general turning applications in Stahl, designed to balance wear resistance and reliable chip formation.

Tiger·tec Gold coating for high wear resistance
RP7 chipbreaker for reliable chip control
Triangular 60° shape for versatile turning
1.6 mm corner radius for stable cutting edge

Maximise tool life and reduce downtime

The combination of the Tiger·tec Gold coating and the WPP20G carbide grade provides enhanced abrasion resistance and thermal stability, which translates into prolonged tool life under typical turning conditions in Stahl. The coating technology reduces flank wear and supports steady cutting forces, so process windows remain stable across medium to high cutting speeds. This stability helps to lower tool-change frequency and maintain production rhythm without complex interventions.

Consistent chip control and surface quality

The RP7 chipbreaker is tuned for predictable chip formation when machining Stahl, promoting short, controllable chips that evacuate reliably from the cutting zone. The insert’s triangular 60° geometry and 1.6 mm corner radius contribute to a robust cutting edge that resists chipping and supports a consistent surface finish. These features together reduce the need for rework and support reproducible part quality in serial production.

Clear material application and machining guidance

Designed for the ISO P material group, the insert is suitable for unalloyed and alloyed Stahl where typical heat generation and chip behaviour are encountered. The negative 0° relief angle provides a stable cutting geometry for turning operations that require rigidity and edge strength. For best results, match cutting data to the workpiece grade and machine capability; the insert’s specification favours conservative feeds with higher cutting speeds to exploit the coating’s thermal benefits while maintaining edge life.

Practical mounting and economic effect

The triangular form offers three usable cutting edges per index, enabling economical use of the insert before replacement. The plate’s dimensions and thickness code contribute to axial and radial stiffness, which is beneficial for medium-depth turning and interrupted cuts where edge robustness is required. Choosing this insert supports predictable tool-change intervals and an efficient inventory strategy for workshop tooling.
