Drilling/Boring Indexable Insert P4840P-6R-E57 WKP35S — for Steel and Cast Iron (Walter Tools)

The P4840P-6R-E57 WKP35S is a coated carbide indexable insert from the Tiger‑tec Silver series, engineered for high‑productivity drilling and boring applications in steel and cast iron.

• Tiger‑tec Silver coated carbide WKP35S
• Optimised for steel and cast iron machining
• Stable chip control 6R‑E57 geometry
• High productivity and consistent edge life

Built for productive drilling and boring cycles

The Tiger‑tec Silver grade combines a coated carbide substrate with advanced surface engineering to address the thermal and mechanical demands of holemaking in steel and cast iron. The WKP35S grade is tuned for the typical heat generation when machining steels and for the abrasive, often short‑breaking chips from cast materials. The integrated 6R‑E57 chipbreaker promotes controlled chip formation and evacuation, which reduces interruption time and supports steady cycle times on automated drilling or boring centres. This results in a measurable improvement in machining throughput without sacrificing component quality.

Predictable tool life and lower unit costs

Consistent cutting edge behaviour contributes directly to a lower cost per part. The coating and substrate combination of the WKP35S grade increases edge life under the cyclic stresses of holemaking, so fewer indexable changes are required and less unplanned downtime occurs. Stable chip control from the 6R‑E57 geometry minimises workpiece rework and toolholder cleaning intervals, supporting a more predictable production schedule and allowing planners to calculate machining costs with greater certainty. For process engineers, this translates to improved budget planning and resource allocation.

Simple integration with standard toolholders and cutting data

The insert is designed for straightforward integration into common drilling and boring tool systems; compatibility depends on the specific holder geometry and catalogue recommendations. For best results, match the cutting data to material group and tool diameter, and consider coolant strategy to maintain consistent temperatures in the cutting zone. If cutting parameters require optimisation, Metav Werkzeuge can provide application support and tailored recommendations to align spindle speed, feed per revolution and depth of cut with the WKP35S performance profile.

Clear material suitability and application guidance

According to ISO segmentation, this grade addresses the P and K workpiece groups: ISO 513 P for a wide range of steels and K for cast iron variants. The insert is especially effective where the application demands both wear resistance and thermal stability, for example in medium‑to‑long production runs and in catalogued geometries where hole accuracy and surface finish are critical. Its design supports productive machining of common engineering steels and grey or nodular cast irons without compromising surface integrity.
