CNMG190612-RP7 WPP20G indexable turning insert — Tiger‑tec Gold, RP7, for Stahl by Walter Tools

The CNMG190612-RP7 WPP20G is an indexable turning insert engineered for productive Stahl machining with a coated carbide grade optimised for balanced wear resistance and toughness.

Tiger‑tec Gold coating for extended tool life
RP7 chipbreaker for stable chip control
Rhombic 80° form for versatile turning
1.2 mm corner radius for reliable edge strength

High-performance cutting for consistent Stahl results

The CNMG190612-RP7 insert combines the Tiger‑tec Gold coating with a coated carbide substrate to deliver reliable performance when machining Stahl (ISO group P). The coating technology improves resistance to abrasive wear while maintaining edge integrity under the thermal loads typical for turning Stahl. This results in fewer interruptions for tool changes and a more predictable tool life, which supports stable production planning and lower unit costs over longer runs.

Stable chip control and secure cutting edge

A chipforming geometry with the RP7 breaker and a 0° (negative) clearance angle promotes controlled chip formation and evacuation during conventional turning. The controlled chip flow reduces the risk of built-up edge and unplanned downtime, which is particularly valuable in medium to high-volume operations. The negative rake style improves security at the cutting edge, enabling confidence in interrupted cuts and roughing steps.

Economical productivity through grade design and coating

The WPP20G grade within the Tiger‑tec Gold family is a coated carbide composition designed as a universal, wear-resistant option for Stahl applications. The formulation balances hardness and toughness to perform across a broad range of feeds and depths of cut, helping to reduce tool inventory complexity. Optimised wear resistance means longer intervals between indexings, contributing to measurable savings in both tool cost and machine hours.

Geometry and tolerance for flexible integration

The rhombic 80° insert shape, combined with a 1.2 mm corner radius and an insert size of 19, provides a versatile geometry suitable for turning, facing and light profiling operations. The plate thickness 06, tolerance class M and execution G indicate a standardised fit for compatible toolholders, allowing straightforward integration into existing tooling systems. These dimensional characteristics support repeatable set-ups and consistent surface finishes on Stahl components.
