P4841P-1R-E57 WKP35S – drilling/reaming indexable insert with Tiger·tec Silver coating | Walter Tools

A P4841P-1R-E57 WKP35S indexable insert designed for drilling and reaming applications, optimised to deliver consistent performance when machining steel and cast iron.

• Tiger·tec Silver coated carbide grade WKP35S
• Optimised for steel and cast iron machining
• Stable chip formation for consistent results
• High wear resistance for longer tool life

Increase throughput with a wear-resistant coating and consistent chip control

The combination of the Tiger·tec Silver coating and the WKP35S grade provides a clear productivity advantage: improved wear resistance reduces downtime for insert changes and maintains dimensional stability across longer production runs. As a coated carbide cutting solution, this insert is designed to cope with the heat and abrasion typical of machining unalloyed and alloyed steels, which supports faster cycle times and more reliable planning of tool-change intervals. The result is measurable process stability and fewer interruptions.

Reliable chip behaviour and predictable surface quality for steel and cast iron

Built around a specific chipbreaker geometry (1R‑E57), the insert promotes stable chip formation, which reduces the risk of built-up edge and improves surface finish on challenging materials. Its geometry and coating combination have been selected for the typical chip characteristics of both steel and cast iron, so machinists benefit from controlled chip flow and fewer secondary operations. This translates into consistent part quality and reduced rework, particularly in serial manufacturing and demanding workshop environments.

Practical application notes and advantages in production settings

This insert is suitable for drilling and reaming operations where repeatable results and cost-effective tool life are priorities. The indexable insert concept allows for rapid index changes, lowering set-up time and supporting lean workflows. Because the grade targets the P/K material groups, it is a versatile option across mixed production runs that include both steel and cast iron components. Integrating these inserts into existing toolholders typically yields immediate gains in stability and repeatability without complex process changes.

FAQ

What materials is this insert suited for?

The P4841P-1R-E57 WKP35S insert is specified for the P and K material groups, meaning it is suited for machining steel (P) and cast iron (K).

What is the advantage of the Tiger·tec Silver coating?

The Tiger·tec Silver coating on the WKP35S grade improves thermal resistance and wear properties, which contributes to longer life and more consistent performance during drilling and reaming.

Which chipbreaker is used and why does it matter?

The insert uses the 1R‑E57 chipbreaker, which promotes stable chip formation and helps maintain surface quality and process reliability in serial machining.

Can this insert be used for finishing operations?

While primarily designed for reliable drilling and reaming, the controlled chip behaviour and wear resistance of the WKP35S grade can support fine finishes where geometry and cutting parameters are appropriately set.

How does this insert support productivity in a production environment?

By combining a robust coated carbide substrate with an optimised chipbreaker and the Tiger·tec Silver coating, the insert reduces tool-change frequency and improves repeatability, helping to streamline machining cycles.
