P2840S-1N-F57 WKP35S Wendeplatten - Walter Tools

Efficient machining of steel and cast iron is achieved with the combination of the WKP35S coated-carbide grade and the Tiger·tec Silver series; this results in stable chip formation and extended tool life. Benefit from the optimised 1N‑F57 chipbreaker for reliable drilling and boring cycles, and order or consult Metav Werkzeuge for application advice.

P2840S-1N-F57 WKP35S – drill/reaming indexable insert for steel and cast iron by Walter Tools

A P2840S-1N-F57 WKP35S indexable insert engineered for productive drilling and boring in steel and cast iron, utilising the Tiger·tec Silver coated‑carbide technology

• Tiger·tec Silver coated carbide for long life
• Optimised chip control for steel and cast iron
• Stable cutting edge for consistent surface quality
• Suitable for productive drilling and boring

Maximised productivity through engineered coating and grade

The combination of the WKP35S grade and the Tiger·tec Silver coating delivers a measurable improvement in machining stability for P and K materials. Designed specifically for drilling and reaming operations, the insert achieves stable chip formation even under varying cutting conditions. The coated carbide layer reduces abrasive wear and improves thermal resistance, which translates into fewer tool changes and a smoother production flow. For workshops aiming to increase output without compromising dimensional accuracy, this insert provides a clear, cost‑effective advantage.

Reliable chip control and geometry that reduces downtime

The 1N‑F57 chipbreaker geometry is optimised to handle the short, breaking chips typical of cast iron and the continuous chips from many steels. This engineered chip control reduces the risk of chip accumulation and tool interference, supporting safer, longer uninterrupted cycles. The geometry also contributes to consistent surface finish and repeatable hole quality, which is particularly valuable for batch production and assembly operations where tolerance adherence is critical. The result is improved process reliability and lower per‑part machining cost.

Practical application advice and process benefits

Suitable for unalloyed and alloyed steel as well as cast iron, the insert is intended for integration into standard drill and boring holders compatible with this ISO designation. The grade and coating combination emphasises tool life and reproducibility, while the insert geometry supports controlled heat generation and predictable wear patterns. For manufacturers pursuing consistent component quality and reduced rework, this insert assists in achieving those targets by focusing on stability, wear resistance and predictable chip evacuation.
