P4841P-7R-A57 WKP35S drill/reaming indexable insert, Tiger·tec Silver – for steel and cast iron (Walter Tools)

P4841P-7R-A57 WKP35S is an indexable insert designed for drilling and reaming tasks where robust chip control and repeatable performance are required in steels and cast iron

• Tiger·tec Silver coating technology
• WKP35S coated carbide grade
• Optimised for steel and cast iron

Longer tool life through advanced coating and grade

The combination of the Tiger·tec Silver coating with the WKP35S grade results in a wear-resistant surface that reduces flank and crater wear during interrupted drilling cycles. As a coated carbide solution, this insert balances toughness and hardness to withstand the thermal loads typical of steel machining while maintaining low abrasive wear when facing cast iron. The protective coating improves lubricity at the cutting edge, which lowers friction and helps preserve tool geometry over longer production runs, translating into fewer tool changes and increased uptime.

Consistent chip control and safer machining

The integrated 7R-A57 chipbreaker geometry is engineered for reliable chip control when machining ISO group P (steel) and ISO group K (cast iron). Short, predictable chips reduce the risk of entanglement in drilling and reaming operations and facilitate automatic chip evacuation, improving surface quality and process stability. The insert’s geometry supports steady cutting forces and a stable cutting edge, which contributes to a safer machining environment and more consistent hole quality across batches.

Productivity and process reliability for drilling and reaming

With a geometry optimised for drill/reaming applications, the P4841P-7R-A57 format delivers accurate seating and repeatability in tool holders, reducing set-up times and alignment checks. The insert’s construction promotes stable cutting conditions that help achieve higher feed rates where permissible, so cycle times shorten without compromising bore integrity. The result is improved productivity and predictable performance for component series requiring tight tolerances and regular production runs.

FAQ

What materials is this insert suitable for?
The P4841P-7R-A57 WKP35S insert from Walter Tools is specified for ISO group P (steel) and ISO group K (cast iron), making it suitable for a wide range of unalloyed and alloy steels as well as typical cast-iron grades.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on this Walter Tools insert enhances wear resistance and reduces friction at the cutting edge, which prolongs tool life and supports higher process reliability under cyclic thermal and mechanical loads.

How does the 7R-A57 chipbreaker improve drilling and reaming?
The 7R-A57 chipbreaker produces short, controllable chips that evacuate cleanly during drilling and reaming, reducing entanglement risks and improving surface finish and hole integrity.

Can this insert be used for stainless steel applications?
Stainless steel is not listed among the specified compatible materials; the P4841P-7R-A57 WKP35S is optimised for steel and cast iron according to the provided specification.

What manufacturing benefits does the insert provide for batch production?
By combining a robust coated carbide grade with optimised geometry, the insert delivers repeatable seating, lower tool-change frequency and consistent hole quality, all of which contribute to reduced cycle times and higher throughput.
