P2840S-2N-A57 WKP35S — Drill/Boring indexable insert, Tiger·tec Silver by Walter Tools

P2840S-2N-A57 WKP35S is an indexable insert engineered for drilling and boring applications, optimised for steel and cast iron to ensure controlled chip formation and extended tool life.

• Tiger·tec Silver coating for enhanced wear resistance
• WKP35S grade optimised for steel and cast iron
• 2N-A57 chipbreaker for stable chip control
• Indexable insert for drilling and boring operations

Consistent productivity through advanced substrate and coating

The coated carbide grade WKP35S, incorporating Tiger·tec Silver technology, is designed to balance wear resistance and toughness for demanding machining tasks. This combination reduces flank and crater wear under typical drilling and boring loads, making it easier to maintain productive cutting parameters over longer tool life. For operations in the ISO material groups P (steel) and K (cast iron), the insert’s substrate and coating interaction mean fewer tool changes and more predictable replacement intervals, which supports throughput and reduces machine downtime.

Precise chip control for safer, faster cycles

Controlled chip formation is central to reliable holemaking. The 2N-A57 chipbreaker geometry directs chips away from the cutting zone and encourages short, easy-to-manage fragments during drilling and boring. As a result, chip evacuation is improved, workpiece surface finish is stabilised and the risk of entanglement is lowered. These benefits translate into fewer interruptions for clearing chips and a smoother production rhythm, especially in automated or high-volume setups where consistent cycles are critical.

Application compatibility and practical selection guidance

The insert is suited for a broad range of steels and cast irons as indicated by the P/K designation under ISO 513 principles; this means it is optimised for the thermal and mechanical behaviour typical of these materials. For best results, pair the insert geometry with appropriate drill bodies and follow manufacturer-recommended cutting data—feed and speed adjustments influence chip form and tool life more than many realise. When selecting tooling for specific workpiece grades or hole tolerances, consider the interaction of insert grade, chipbreaker and holder rigidity to achieve the required surface quality and repeatability.
