P4841P-3R-E57 WKP25S Drill/reamer indexable insert, Tiger·tec Silver — Walter Tools

The P4841P-3R-E57 WKP25S is an indexable insert designed for drilling and boring operations, optimised for machining steel and cast iron in industrial production environments.

• Tiger·tec Silver coating technology
• WKP25S coated cemented carbide grade
• Optimised for steel and cast iron machining
• Stable chip formation and high productivity

Increase throughput with a high-performance coating

The Tiger·tec Silver surface treatment and the WKP25S grade deliver a measurable improvement in process stability and tool life. As a coated cemented carbide solution, the insert resists abrasive wear and maintains a sharp cutting edge for longer, which reduces the frequency of tool changes and supports continuous production. The result is higher part throughput with fewer interruptions and more consistent dimensional results during drilling and reaming tasks.

Consistent chip control for dependable results

Equipped with the chipbreaker 3R-E57, the geometry promotes controlled chip formation and evacuation, reducing the risk of built-up edge and improving surface finish. The insert is engineered for material groups P / K, which corresponds to steel and cast iron machining under ISO 513. For operations where repeatable chip shape and reliable evacuation are essential, this insert helps maintain cycle times and lowers the probability of part rejects.

Broad material coverage reduces tooling complexity

The WKP25S grade is a versatile, coated carbide formulated to cover a wide material range typical in general machining shops. Its balanced combination of hardness and toughness makes it suitable for unalloyed and alloyed steels as well as many cast irons, allowing fewer grade swaps across mixed production batches. For customers with variable batch mixes, this reduces inventory complexity and streamlines tool management without compromising performance.

Practical integration and selection guidance for production

The insert’s geometry and grade make it suitable for standard drilling and boring tool bodies that accept exchangeable indexable inserts, facilitating straightforward retrofitting. The cutting data recommended for P / K groups will achieve consistent results when combined with appropriate feeds and speeds for the workpiece and machine rigidity. For tailored cutting parameters and matching toolholders, Metav Werkzeuge’s consultants can provide specific recommendations to integrate the insert into an existing process.
