P4841P-7R-E57 WKP25S – Drill / Boring Indexable Insert, Tiger‑tec Silver (Walter Tools)

The P4841P-7R-E57 WKP25S is a precision drill and boring indexable insert designed for efficient machining of steel and cast iron, optimised for productive metalcutting operations.

• Tiger‑tec Silver coated grade WKP25S
• Optimised chipbreaker 7R‑E57
• Suited for steel and cast iron machining
• Indexable insert for drilling and boring

Consistent tool life through Tiger‑tec Silver coating

The coated cemented carbide grade WKP25S, part of the Tiger‑tec Silver series, delivers improved wear resistance and stable chip formation during prolonged drilling cycles. The coating architecture reduces adhesive and abrasive wear mechanisms typical when machining steel and cast iron, which translates into longer tool life and fewer interruptions for indexable insert changes. For production environments that prioritise uptime, this means more reproducible component quality and predictable maintenance intervals.

Precise chip control for safer, faster cuts

The dedicated chipbreaker 7R‑E57 geometry provides controlled fragmentation of chips in both drilling and boring operations, reducing the risk of entanglement and improving coolant access at the cutting edge. The result is improved surface finish and reduced load variation on the toolholder, which supports stable feeds and speeds. As an indexable insert engineered for these applications, it enables quick insert replacement and consistent cutting behaviour across repeated cycles, supporting higher process reliability and throughput.

Practical integration and technical support for production

This insert is specified for the ISO material groups P (steel) and K (cast iron), offering a straightforward selection criterion for production engineers and purchasing. Walter Tools’ established reputation for precision tooling supports process consistency and cutting-edge performance in demanding applications.
