P4840P-2R-E57 WKP25S drilling/boring indexable insert – Tiger·tec Silver, for steel and cast iron | Walter Tools

A P4840P-2R-E57 WKP25S indexable insert engineered for high-productivity drilling and boring applications in steel and cast iron.

• Tiger·tec Silver coated carbide grade WKP25S
• Optimised for steel and cast iron machining
• Stable chip control and long tool life

High-performance coating and substrate for demanding cuts

The insert is produced in the Tiger·tec Silver series and uses the WKP25S coated carbide grade, designed specifically to cope with the thermal and mechanical demands of steel (P) and cast iron (K). The combination of a wear-resistant coating and a tough substrate reduces flank and crater wear during interrupted or continuous cuts, which translates into longer tool life and fewer index changes. For procurement and process planners this means improved uptime and predictable replacement intervals.

Precision chip control that increases productivity

Equipped with the 2R-E57 chipbreaker geometry, the indexable plate offers controlled chip formation for a wide range of feed and speed settings. The defined chip flow reduces re-cutting of swarf and lowers the risk of tool-induced vibration, delivering a consistent surface quality and fewer secondary operations. In production terms, better chip control contributes directly to shorter cycle times and enhanced process security in batch and single-part machining.

Practical advantages for workshop management and tool life

The plate’s material compatibility (ISO groups P/K) gives machining operations flexibility across common workpiece families without needing multiple specialised grades. The insert format simplifies tool inventory and replacement procedures: fewer SKUs are required to cover turning, drilling or boring tasks in mixed-production environments. Together with Walter Tools’ established cutting-edge geometries, this solution supports reproducible performance and easier process standardisation on the shop floor.

FAQ

What materials is this insert suitable for?
The P4840P-2R-E57 WKP25S insert is designed for steel (P) and cast iron (K) applications according to ISO group designations, offering robust performance across typical shop-floor steels and many cast-iron grades.

How does the 2R-E57 chipbreaker affect machining?
The 2R-E57 chipbreaker promotes controlled chip formation and evacuation, reducing vibration and improving surface finish; this geometry supports more stable cutting in drilling and boring operations.

Can this grade be used for interrupted cuts?
Yes. The WKP25S coated carbide grade from the Tiger·tec Silver line provides improved edge stability suitable for interrupted and continuous cutting conditions commonly encountered in drilling and boring.
