P4841P-6R-E57 WKP25S drilling/boring indexable insert – Tiger·tec Silver, for steel and cast iron (Walter Tools)

A P4841P-6R-E57 WKP25S indexable cutting insert designed for drilling and boring operations where long life and reliable chip control are essential

• Tiger·tec Silver coating for extended life
• WKP25S grade for reliable wear resistance
• 6R‑E57 chipbreaker for controlled chips
• Suited to steel and cast iron machining

Proven performance and economy in production

The combination of the Tiger·tec Silver coating with the WKP25S grade delivers a balance of wear resistance and toughness that directly improves process economy. Coating technology reduces abrasive wear and thermal sensitivity, which prolongs tool life and reduces changeover frequency; this leads to lower tooling costs per part and steadier production throughput. The insert’s design targets predictable edge behaviour, enabling planners and operators to calculate tool cycles with greater confidence and to plan maintenance intervals more accurately.

Stable chips and improved surface results

The 6R‑E57 chipbreaker geometry controls chip formation for both short, breaking chips typical of cast iron and the continuous or segmented chips produced when machining steel. Controlled chips reduce the risk of surface damage and interruption, improving surface finish and dimensional consistency. The insert’s characteristics help maintain stable cutting forces, which supports repeatable machining and simplifies fixture and coolant strategies on the shop floor.

Broad material application and integration benefits

Classified for ISO groups P (steel) and K (cast iron), this coated carbide grade is suitable for a wide range of unalloyed and alloyed steels as well as various cast irons. The insert is compatible with standard indexable cutting toolholders used in drilling and boring operations, allowing straightforward integration into existing tool systems. With consistent performance under typical cutting conditions, the product supports higher productivity and predictable results, which are valuable for production planning and quality assurance.

FAQ

Is this insert suitable for stainless steel applications?
The P4841P-6R-E57 WKP25S insert is optimised for ISO group P (steel) and K (cast iron); performance on stainless steel is not specified and should be verified with a process trial.

What advantages does the Tiger·tec Silver coating offer?
Tiger·tec Silver reduces abrasive wear and helps maintain edge integrity under thermal load, extending the service life of the insert and improving process stability when machining steel and cast iron.

How does the 6R‑E57 chipbreaker affect production?
The 6R‑E57 geometry produces controlled chips that reduce rework risk and support consistent surface quality, which contributes to fewer interruptions and more predictable cycle times.

Can the insert be used in standard indexable drilling holders?
Yes, the insert is designed for integration with common indexable toolholders for drilling and boring, allowing easy replacement and compatibility within established tool systems.
