P4840P-8R-F57 WKP35S Drill/Boring Indexable Insert — for Steel and Cast Iron — Walter Tools

P4840P-8R-F57 WKP35S is a drill/boring indexable insert engineered for high-productivity metalworking in steel and cast iron applications

• Tiger‑tec Silver coating for high wear resistance
• WKP35S grade for reliable, repeatable performance
• Optimised 8R‑F57 chipbreaker for controlled chips
• Suitable for steel (P) and cast iron (K) machining

Maximum machining performance through advanced coating and substrate

The combination of the Tiger‑tec Silver coating and the WKP35S carbide grade delivers higher abrasion resistance and stable edge life under typical drilling stresses. The coating reduces friction and thermal load on the cutting edge, which in turn helps to maintain cutting geometry over longer cycle times. For workshop managers and process engineers this means fewer indexable changes, improved tool-life predictability and more consistent component tolerances when machining steel and cast iron according to ISO 513 material group classification.

Predictable chip control and improved cycle times

An optimised 8R‑F57 chipbreaker geometry controls chip formation during drilling and boring operations, reducing the risk of long, stringy chips or excessive recutting. Controlled chip flow lowers heat build-up and diminishes tool wear, which supports higher effective feed rates and shorter non-cutting times for chip disposal. The insert’s geometry is tailored to common drilling/boring kinematics, offering a clear technical advantage in maintaining surface integrity and repeatable hole quality across series production.

Seamless integration into productive tool systems

Designed as an indexable insert for drilling and boring, this cutting solution is compatible with standard toolholders for insert-based drilling systems and integrates into existing machining cycles without complex retooling. The insert is specified for the material groups P (steel) and K (cast iron), making it appropriate for mixed-production environments where both materials are processed. Process planners benefit from the predictable behaviour of a coated carbide grade and defined chipformer, which simplifies parameter selection and shortens setup validation times.

FAQ

What materials can this insert machine effectively?
The P4840P-8R-F57 WKP35S insert is designed for steel (ISO group P) and cast iron (ISO group K) applications, matching the intended use of the WKP35S grade and Tiger‑tec Silver coating.

How does the 8R‑F57 chipbreaker improve drilling performance?
The 8R‑F57 chipbreaker controls chip shape and evacuation during drilling and boring, reducing recutting and heat generation so that the insert delivers more consistent hole quality and longer edge life.

Is the insert compatible with standard drilling indexable systems?
Yes, the drill/boring indexable insert fits common insert-based drilling toolholders and is intended for straightforward integration into existing machining setups.

How does the Tiger‑tec Silver coating benefit tool life?
The Tiger‑tec Silver coating lowers friction and improves thermal stability at the cutting edge, which helps to resist abrasive wear and extend the service interval of the insert under production conditions.
