CNMG120412-RP7 WKP30S turning indexable insert — for steel & cast iron, Tiger‑tec Silver, Walter Tools

The CNMG120412-RP7 WKP30S is a rhombic 80° indexable turning insert with a 0° negative rake, designed for productive machining of steel and cast iron in demanding production environments.

Tiger‑tec Silver coating for extended tool life
WKP30S grade for steel and cast iron machining
RP7 chipbreaker for consistent chip control
80° rhombic form with 1.2 mm corner radius

Reliable cutting performance from a modern coated grade

The WKP30S grade, applied within the Tiger‑tec Silver family, is a coated carbide designed for stable cutting in mixed production runs. Its composition balances wear resistance and toughness, which results in extended tool life and fewer unplanned tool changes. For industrial turning where cycle time and repeatability matter, this grade reduces the impact of abrasive wear typical when machining steel and cast iron, so stand‑by time for reconditioning is lowered and spindle utilisation is optimised.

Predictable chip formation and consistent surface quality

The combination of the RP7 chipbreaker, 0° negative rake, and 80° rhombic geometry produces controlled chip flow and stable cutting forces. The 1.2 mm corner radius increases edge strength and helps achieve repeatable surface finish without compromising component tolerances. In practical terms, chip control is improved over a wider range of feeds and depths, reducing interruptions for chip removal and lowering the risk of built‑up edge or vibration‑induced marks on turned parts.

Easy integration and cost‑effective productivity

Produced to M tolerance class and the CNMG ISO form, the insert is compatible with standard clamping systems and indexable toolholders, enabling quick interchange and consistent set‑up. The design supports efficient machining strategies: fewer tool changes, stable process windows and predictable tool‑life curves translate into measurable savings in operator time and machine availability. The CNMG120412-RP7 WKP30S is particularly suited to batch turning where reliability and surface quality are prioritised.

FAQ

What materials is this insert suitable for?
The CNMG120412-RP7 WKP30S from Walter Tools is formulated for machining steel (ISO group P) and cast iron (ISO group K), offering a balance of wear resistance and toughness for these materials.

How does the RP7 chipbreaker benefit production?
The RP7 chipbreaker on this insert promotes predictable chip formation and evacuation, which improves process stability and reduces interruptions on production lathes.

What is the effect of the 1.2 mm corner radius?
A 1.2 mm corner radius provides increased edge strength for heavier cuts while helping to maintain a consistent surface finish and dimensional stability on turned parts.

Is the insert compatible with standard toolholders?
Yes, the insert follows the CNMG ISO form and M tolerance class, enabling straightforward integration into common indexable turning systems.

Can this insert be used for high‑speed cutting?
The Tiger‑tec Silver coating combined with the WKP30S grade is optimised for productive cutting regimes; suitability for high‑speed cutting depends on the specific machine and process parameters.
