P4840P-2R-A57 WKP25S — drilling/boring indexable insert for steel and cast iron (Walter Tools)

P4840P-2R-A57 WKP25S is a high-performance indexable insert engineered for efficient drilling and bore-widening operations in steel and cast iron, combining a robust coated-carbide grade with a specialised chipbreaker for repeatable results.

• Tiger·tec Silver coating technology
• WKP25S coated carbide grade
• Optimised chipbreaker 2R-A57
• For steel (P) and cast iron (K)

Maximise productivity with advanced coating and grade

The combination of the Tiger·tec Silver technology and the WKP25S grade delivers a balance of wear resistance and toughness that is particularly beneficial in interrupted and continuous drilling operations. This insert is a coated carbide solution designed to reduce flank and crater wear, which in turn maintains dimensional stability over longer production runs. The result is fewer tool changes, more consistent cycle times and improved overall throughput on components made from steel and cast iron.

Better chip control and surface quality through optimised geometry

The 2R-A57 chipbreaker is engineered to produce controllable, segmented chips that evacuate reliably from the hole or bore. Controlled chip formation lowers the risk of re-cutting, reduces heat concentration at the cutting edge and supports a stable cutting edge during deep or interrupted cuts. For operations that require predictable surface integrity, the insert’s geometry contributes to a consistent surface finish and reduced risk of built-up edge, especially when machining typical P and K group materials.

Practical advantages for workshop and production environments

As an indexable insert, the component simplifies tool management and enables fast replacement without regrinding, supporting reproducible part quality across shifts. Compatibility with common toolholders and the robust coating technology lead to dependable cycle-to-cycle performance and lower per-part tooling costs. The combination of productivity and process stability makes this insert a practical choice for job shops and production lines seeking to improve machining efficiency while maintaining process reliability.
