P4841P-8R-E57 WKP35S drilling/boring indexable insert by Walter Tools — Tiger·tec Silver coated carbide for steel and cast iron

P4841P-8R-E57 WKP35S is an indexable insert designed for drilling and hole-enlarging operations, optimised for machining steel and cast iron in industrial turning and drilling applications

• Tiger·tec Silver coated carbide
• Grade WKP35S for robust wear resistance
• Geometry P4841P-8R-E57 for drilling/boring tasks
• Suitable for steel and cast iron machining

Reliable cutting performance for steel and cast iron

The Tiger·tec Silver coating combined with the WKP35S cutting grade ensures consistent edge integrity under the thermal and mechanical conditions typical of steel machining. The insert’s design addresses the heat generation and continuous chip formation characteristic of ISO group P (steel), reducing unpredictable wear and prolonging effective cutting life. For cast iron (ISO group K), the same grade adapts to abrasive wear and the short, breaking chips common to those materials, providing a stable machining result with fewer interruptions.

Predictable chip control and process stability

A defined chipbreaker geometry (code 8R-E57) and the P4841P-8R-E57 geometry deliver controlled chip formation that minimises re-cutting and improves surface integrity. By directing chips reliably away from the cutting zone, the insert reduces the risk of workpiece damage and facilitates higher material removal rates without sacrificing surface quality. The combination of coating and grade contributes to repeatable tool life, supporting lean production and fewer tool changes during series runs.

Practical integration into production workflows

The indexable format enables quick seat replacement and straightforward toolset standardisation on drilling and boring heads that accept this geometry. Using the WKP35S grade simplifies grade selection across mixed production runs that include both steel and cast iron, helping to reduce tool inventory complexity. Where consistent results and predictable maintenance intervals are required, this insert supports smoother changeovers and more reliable cycle times.

FAQ

What materials is this insert suitable for?
The WKP35S grade insert is specified for steel (ISO group P) and cast iron (ISO group K), making it suitable for mixed production runs where both materials are present.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating on the insert enhances wear resistance and thermal stability, helping to maintain a sharp cutting edge and consistent performance over extended cycles.

Which chipbreaker and geometry does the insert use?
This insert features the 8R-E57 chipbreaker and the P4841P-8R-E57 geometry, optimised for controlled chip formation in drilling and hole-enlarging operations.

Is this insert compatible with standard indexable drill holders?
The insert follows the specified geometry designation (P4841P-8R-E57) to match drilling and boring toolholders designed for this format; compatibility should be confirmed against the toolholder specifications.
