P2841S-3N-A57 WKP25S Drilling/Boring indexable insert by Walter Tools — Tiger‑tec Silver, for steel & cast iron

The P2841S-3N-A57 WKP25S is a drilling/boring indexable insert engineered for production environments that require consistent cutting results when machining steel and cast iron.

• Tiger‑tec Silver coated carbide grade WKP25S
• Optimised for steel and cast iron machining
• Stable chip formation and long tool life
• High process reliability for production use

Increase uptime with a wear-resistant Tiger‑tec Silver grade

The combination of the Tiger‑tec Silver coating and the WKP25S cemented carbide formulation is designed to extend tool life and reduce tool-change frequency. Coated carbide provides a hard, wear-resistant surface that delays flank and crater wear during continuous drilling and boring cycles, which translates into fewer interruptions and higher overall equipment effectiveness. For production lines where reliability and repeatability matter, this grade offers a measurable advantage in tool longevity and consistent cutting performance.

Achieve reliable chip control and improved surface results

The integrated 3N‑A57 chipbreaker geometry is tuned for the specific chip forms encountered when machining steel (P) and cast iron (K) according to ISO grouping. Stable chip formation reduces the risk of built-up edge and improves evacuation from the cutting zone, which in turn supports a better surface finish and lower rework rates. For less experienced users, the ISO letters P and K indicate suitability for unalloyed/alloyed steels and cast irons respectively, making material selection straightforward and reducing setup uncertainty.

Seamless integration for production-grade drilling and boring

This indexable insert follows common mounting and designation standards, so it is simple to insert into existing drilling and boring toolholders without extensive adaptation. The standardised designation helps maintenance and purchasing teams to reorder the correct item quickly and avoid downtimes. The combination of a process-oriented grade and a proven chipbreaker geometry promotes process security in high-volume machining and supports predictable cycle times for batch production. The insert is particularly useful where repeatable tolerance and surface quality matter across long runs.

FAQ

What materials is this insert suitable for?
The insert is specified for steel (ISO group P) and cast iron (ISO group K); the WKP25S grade and the 3N‑A57 chipbreaker ensure effective performance on these materials.

How does the Tiger‑tec Silver coating benefit production?
The Tiger‑tec Silver coating on the WKP25S grade increases wear resistance and helps maintain a stable cutting edge, which reduces tool changes and supports uninterrupted production.

Can the insert be used with standard drilling holders?
Yes. The designation aligns with common indexable insert standards and enables straightforward integration into compatible drilling and boring toolholders.

What advantage does the 3N‑A57 chipbreaker provide?
The 3N‑A57 chipbreaker produces controlled, short chips when machining cast iron and manageable chip forms in steels, improving evacuation and reducing the chance of chip-related interruptions.

Is this insert suitable for high-volume production?
Designed for production use, the combination of WKP25S grade and Tiger‑tec Silver coating offers process reliability and consistent performance for extended runs.
