P4841P-4R-A57 WKP35S Drilling/Reaming Indexable Insert for Stahl and Cast Iron - Walter Tools

The P4841P-4R-A57 WKP35S is a coated carbide indexable insert from the Tiger‑tec Silver series, engineered for drilling and reaming tasks in Stahl and cast iron applications.

• Tiger‑tec Silver coating for high wear resistance
• Optimised 4R‑A57 chipbreaker for stable chips
• Suitable for Stahl (P) and cast iron (K)
• Coated carbide grade WKP35S for long tool life

Delivering long tool life and consistent throughput

The Tiger‑tec Silver technology combined with the WKP35S grade provides high wear resistance and a stable cutting edge, which reduces downtime for tool changes and regrinds. As a coated carbide solution, this insert balances toughness and hardness to resist abrasive wear from cast materials while maintaining edge integrity in interrupted cuts. The result is more predictable tool life and reduced process variability, supporting higher machine utilisation and lower unit costs per part.

Better chip control for safer, faster machining

The integrated 4R‑A57 chipbreaker is optimised for the typical chip forms encountered when machining Stahl and cast iron. By producing short, controllable chips, the geometry minimises the risk of chip entanglement and reduces the need for secondary chip management. This improvement in chip behaviour contributes directly to surface quality and reduces rework, so production runs complete more smoothly and finishing steps are more consistent.

Practical application: where this insert adds value

Designed as a drilling/reaming indexable solution, the insert supports a range of catalogue-dependent geometries and is suitable where robust, repeatable performance is required. The combination of the Tiger‑tec Silver coating and the WKP35S cutting material makes the grade particularly effective for mixed-series production where both Stahl and cast iron must be addressed without frequent tool changes. The insert’s design enables straightforward mounting in compatible holders and offers an economical alternative to solid tools for high-volume or variable-batch manufacturing.

FAQ

Which workpiece materials are suitable for this insert?
The insert is intended for machining Stahl (ISO group P) and cast iron (ISO group K); the WKP35S grade and Tiger‑tec Silver coating balance abrasive wear resistance and edge stability for these materials.

What does the 4R‑A57 chipbreaker provide?
The 4R‑A57 chipbreaker ensures controlled, short chips during drilling and reaming, improving chip evacuation and reducing the likelihood of chip-related interruptions.

Is this insert appropriate for interrupted cuts or heavy machining?
The coated carbide construction and Tiger‑tec Silver technology give the insert enhanced toughness and wear resistance, making it suitable for many interrupted-cut and moderately heavy-machining scenarios within its intended material groups.

How is the insert identified in catalogues and ordering systems?
This product is listed under the designation P4841P-4R-A57 WKP35S and the SKU P4841P-4R-A57-WKP35S-WALTER; Walter Tools documentation provides matching holder and geometry information.

Can the same grade be used across mixed-series production?
Yes, the WKP35S grade is designed to offer versatile performance across Stahl and cast iron, reducing the need for frequent grade changes when batches include both material types.
