P4841P-2R-E57 WKP25S — Drilling/reaming indexable insert, Tiger‑tec Silver coating, for Steel & Cast iron (Walter Tools)

The P4841P-2R-E57 WKP25S is a coated carbide indexable insert from the Tiger‑tec Silver series, engineered for drilling and reaming tasks in steel and cast iron, delivering consistent performance in demanding production environments

• Tiger‑tec Silver coating for enhanced wear resistance
• WKP25S grade optimised for steel and cast iron
• 2R‑E57 chipbreaker for controlled chip formation
• Consistent edge life for productive machining

Increased tool life through advanced coating technology

The Tiger‑tec Silver coating used on this insert is formulated to resist abrasive and adhesive wear during heavy machining cycles. As a coated carbide grade, WKP25S combines a hard substrate with a specialised surface layer to reduce flank and crater wear, which in turn prolongs the interval between index changes. For production-oriented shops, this translates into fewer tool changes, more uptime and steadier cycle times. The technical integration of a surface treatment specifically designed for the thermal and mechanical loads of drilling and reaming ensures repeatable performance across batches.

Reliable chip control and safer metalworking processes

The 2R‑E57 chipbreaker geometry focuses on predictable chip formation when machining steel (P) and cast iron (K). A controlled chip flow reduces the risk of long, tangled swarf and lowers tool vibration during cutting, improving hole quality and surface integrity. The insert geometry also eases swarf evacuation in drilled holes, which benefits tool stability and reduces the chance of workpiece damage. For CNC machinists and job-shop professionals, better chip control leads to higher first-pass yields and a reduction in secondary operations.

Productivity benefits and application guidance for daily use

Designed for productive machining, this insert supports consistent cutting-edge life and repeatability in serial production. The combination of a robust substrate and the Tiger‑tec Silver surface enables effective heat management and wear resistance in common ferrous materials, reducing unplanned stoppages. Specification and tooling decisions are simplified by the clear material-group suitability (steel and cast iron), allowing planners to standardise on grades that fit a wide range of parts. For tailored feed and speed recommendations, Metav Werkzeuge can provide application-specific data to optimise cycle time and component finish.
