WNMG080408-RP7 WKP30S turning insert – Walter Tools, Tiger·tec Silver, RP7 chipbreaker

WNMG080408-RP7 WKP30S is a trigon 80° negative-indexable turning insert engineered for productive machining of steel and cast iron.

• Tiger·tec Silver coating for wear resistance
• Optimised RP7 chipbreaker for stable chips
• 80° trigon shape, negative 0° clearance
• Suitable for steel and cast iron machining

Longer tool life and consistent performance with Tiger·tec Silver

The WKP30S grade, realised in the Tiger·tec Silver family, combines a coated cemented carbide substrate with a surface technology tuned for machining of steel and cast iron. This results in improved wear resistance and a stable cutting edge under the thermal and mechanical loads typical for P and K group materials (ISO 513). The coating reduces flank wear and protects the substrate at elevated temperatures, which translates into fewer tool changes and a steadier production flow — a direct benefit for workshops prioritising uptime and predictable component quality.

Stable chip formation and reliable geometry for fewer interruptions

The RP7 chipbreaker is designed to produce controlled, short chips in a wide range of turning operations, easing swarf management and decreasing the risk of chip-related interruptions. Combined with the trigon 80° form and a corner radius of 0.8 mm, the geometry delivers a robust cutting edge that tolerates interrupted cuts and heavier engagement. The negative 0° clearance enhances insert strength and rigidity, making the insert particularly suitable where edge robustness and process reliability are decisive for cycle-time stability.

Broad application scope and practical shop-floor advantages

This indexable turning insert covers many common turning tasks across unalloyed and alloyed steels as well as cast irons, indicated by its material designation P / K. The versatile combination of grade, chipbreaker and plate form supports a balanced compromise between surface finish and edge life, making the insert a good fit for medium-duty turning where consistent component tolerances and repeatability matter. Procurement through Metav Werkzeuge ensures rapid access to the WNMG080408-RP7 WKP30S and application guidance to match the insert to cutting parameters and holder choices for each specific job.

FAQ

What materials is this insert suitable for?
The WNMG080408-RP7 WKP30S is formulated for machining steel and cast iron (material groups P and K according to ISO 513), offering a balance between edge life and chip control for those materials.

How does the RP7 chipbreaker affect machining?
The RP7 chipbreaker on this insert produces short, manageable chips and promotes consistent chip formation, which reduces interruptions and simplifies swarf handling during turning operations.

What is the advantage of the 80° trigon form and negative 0° clearance?
The trigon 80° shape provides positive seating and multiple usable cutting edges, while the negative 0° clearance increases insert strength and rigidity, improving resistance to edge chipping in heavier or interrupted cuts.

What does the WKP30S grade indicate?
WKP30S denotes a Walter coated carbide grade in the Tiger·tec Silver range, tuned for wear resistance and thermal stability when machining steels and cast irons.

Is a 0.8 mm corner radius suitable for general turning?
A corner radius of 0.8 mm offers a compromise between edge strength and surface finish, making it appropriate for general turning where moderate robustness and acceptable finish are required.
