P4841P-4R-E57 WKP35S — drilling/reaming indexable insert (Tiger·tec Silver) by Walter Tools

P4841P-4R-E57 WKP35S is a coated carbide indexable insert designed for productive machining of steels and cast irons in industrial drilling and reaming operations.

*Tiger·tec Silver coating for process security
*WKP35S coated carbide grade for long life
*Chipbreaker 4R-E57 for stable chip control
*Designed for steel (P) and cast iron (K)

Greater uptime through a wear-resistant grade

The use of Tiger·tec Silver technology in the WKP35S grade results in a coated carbide insert that is engineered to resist abrasive wear and maintain a stable cutting edge over extended cycles. This stability reduces the frequency of tool changes, which directly lowers machine idle time and supports higher overall equipment effectiveness. The coating system also contributes to consistent edge integrity in interrupted cuts, which is especially valuable when machining cast components or mixed batches.

Improved chip control for safer, faster cycles

The 4R-E57 chipbreaker geometry is tailored to produce compact, predictable chips when working with both steel and cast iron. Controlled chip formation reduces the risk of entanglement, supports consistent coolant flow, and enables higher feed rates where machine and workpiece rigidity permit. For production environments the result is fewer interruptions and a smoother material flow through the manufacturing process.

Reliable surface quality and repeatable results

A combination of the grade and geometry delivers reproducible surface finishes and dimensional stability part-to-part. The hardened coating and substrate pairing minimise edge degradation, which preserves cutting performance over many components. This repeatability supports quality control targets and lowers scrap rates, delivering a measurable process advantage in series production and small-batch runs alike.

Practical compatibility and application notes

The insert designation P4841P-4R-E57 WKP35S corresponds to a drilling/reaming insert format that is compatible with cutter systems designed for indexable plates of this type. The grade is optimised for ISO material groups P (steel) and K (cast iron), addressing the typical heat and chip characteristics of those materials. Selection of speeds and feeds should follow machine capability and rigidity guidelines; the insert is intended for productive machining rather than fine finishing.

FAQ

Which materials are best suited to this insert?
The P4841P-4R-E57 WKP35S insert is optimised for steel (P) and cast iron (K) applications following ISO material groupings, making it suitable for a wide range of unalloyed and alloyed steels as well as grey and nodular cast irons.

What does the WKP35S grade provide?
The WKP35S grade, part of the Tiger·tec Silver family from Walter Tools, is a coated carbide formulation designed for enhanced wear resistance and extended tool life in demanding drilling and reaming operations.

How does the 4R-E57 chipbreaker affect machining?
The 4R-E57 chipbreaker promotes compact, controlled chips for safer evacuation and reduced risk of clogging, improving cycle stability and enabling higher productive feeds where machine rigidity permits.

Is this insert compatible with indexable drill holders of the same designation?
Yes, the insert follows the P4841P-4R-E57 designation and is intended for cutter bodies and holders that accept this indexable plate format; compatibility should be confirmed with the cutter system documentation.

What operational benefits can be expected in series production?
Using the WKP35S insert yields longer edge retention and predictable chip behaviour, which together reduce tool changes, improve uptime and support consistent part quality across production batches.
