P2841S-5N-A57 WKP25S – Indexable drill/boring insert, Tiger‑tec Silver, Walter Tools

The P2841S-5N-A57 WKP25S is an indexable cutting insert designed for drilling and bore-enlarging operations, optimised for machining steel and cast iron.

• Tiger‑tec Silver coating technology
• WKP25S coated carbide grade
• Optimised for steel and cast iron machining
• Stable chip formation and productive cutting

Engineered for reliable drilling and boring performance

The insert is based on the Tiger‑tec Silver family and the WKP25S coated carbide grade, engineered to withstand the thermally demanding conditions of steel machining while maintaining wear resistance against abrasive cast iron. This combination results in consistent cutting behaviour and helps to reduce the frequency of tool changes. The geometry and coating synergy support predictable tool life and minimise process variation, which directly contributes to uninterrupted production and a lower cost per hole in high‑volume operations.

Consistent chip control reduces interruptions

The integrated 5N‑A57 chipbreaker is designed to produce controlled, repeatable chip shapes when working with both steel (P) and cast iron (K). Improved chip control prevents clogging and reduces the risk of rework or machine stoppages. For machining environments that alternate between interrupted cuts and continuous runs, this insert’s chipformer and coated substrate deliver smoother evacuation and less heat concentration at the cutting edge, translating into longer edge life and fewer unscheduled interventions.

Productivity gains through process reliability

Using a grade and coating technology aligned to the workpiece material enables higher cutting data and more aggressive feed strategies where appropriate. The coated carbide substrate supports reliable cutting under varying conditions, offering measurable productivity benefits such as fewer indexings, reduced tool inventory turnover and improved spindle uptime. These operational gains are particularly relevant for job shops and production cells aiming to increase throughput without compromising surface finish or dimensional stability.

Material compatibility and practical application advice

Marked for workpiece groups P and K, the insert is suitable for a wide range of unalloyed and alloyed steels as well as common cast irons. The designation and geometry make it suitable for integration into standard indexable drill and boring toolholders that accept the P2841S family of inserts. For best results, match the insert grade with coolant strategy and holder rigidity: steel applications tend to benefit from controlled coolant and stable clamping, while cast iron machining often tolerates higher chip-breaking demands.
