P4841P-4R-E57 WKP25S drilling/boring indexable insert, Tiger‑tec Silver – for steel & cast iron | Walter Tools

A P4841P-4R-E57 WKP25S insert engineered for high process stability in drilling and boring, combining a proven chipbreaker geometry with Tiger‑tec Silver coating technology for reliable performance in ISO P and K materials.

• Tiger‑tec Silver coated carbide grade WKP25S
• Optimised 4R‑E57 chipbreaker for stable chips
• Suited for steel (P) and cast iron (K)
• High process reliability for drilling/boring

Delivering consistent chip control for reliable drilling

The combination of the 4R‑E57 chipbreaker geometry with the WKP25S cutting grade provides predictable chip control during drilling and boring operations in ISO P and K materials. This inserts’ geometry reduces irregular chip formation and minimises the risk of jamming, which helps to sustain steady feed rates and reduces unplanned interruptions. The design supports stable cutting forces and improved heat management, which together contribute to longer tool life and fewer tool changes in continuous production runs.

Coating and grade technology that extend tool life and uptime

Built on coated carbide technology within the Tiger‑tec Silver series, the insert is optimised for combined wear resistance and edge robustness. The coating strategy reduces abrasive wear when machining cast iron and mitigates flank wear during steel machining, delivering measurable improvements in wear resistance and process reliability. For operations that prioritise productivity, this results in fewer indexings and maintenance cycles, enhancing overall production efficiency without sacrificing surface quality.

Integration into machining processes and practical benefits

As an indexable insert for drilling and boring tool systems, the item is compatible with standard Walter Tools toolholders designed for insert geometry P4841P‑type. The plate’s balanced geometry supports stable cutting edges that lower vibration and help maintain hole quality over time. For optimal results, match the plate to appropriate feeds and speeds recommended for ISO P and K groups and ensure secure clamping in the chosen holder; this approach yields repeatable results and supports consistent part tolerances across batches.
