P4840P-5R-A57 WKP25S drilling/boring indexable insert – Tiger‑tec Silver, Walter Tools

P4840P-5R-A57 WKP25S is an indexable insert designed for drilling and boring operations, optimised for machining steel and cast iron with reliable chip control and extended edge life

• Tiger‑tec Silver coating for wear resistance
• WKP25S coated carbide grade for steel and cast iron
• Geometry 5R‑A57 for stable chip formation
• Suitable for drilling and boring indexable systems

Maximise productivity with advanced coating technology

The Tiger‑tec Silver coating in this insert combines thermal stability and a low‑friction surface, which reduces built‑up edge and helps maintain cutting performance over longer cycles. For everyday workshop use, that means fewer tool changes and steadier cycle times; the coating is especially effective in applications where heat generation is significant. In plain terms, the technology helps the insert retain its stable cutting edge and supports consistent surface finish and dimensional accuracy during extended runs.

Built for steel and cast iron with predictable chip behaviour

Designed for the ISO groups P (steel) and K (cast iron), the grade WKP25S balances toughness and hardness to resist abrasive wear while avoiding premature fracture. The specified geometry 5R‑A57 promotes short, controlled chips when cutting cast iron and stable, continuous chips in many steels, simplifying chip evacuation. For engineers and production planners, this translates into fewer interruptions and more predictable machining windows, particularly on medium to heavy duty drilling and boring tasks.

Economic tool life and machining reliability

The insert’s coated carbide substrate and tailored micro‑geometry produce a combination of wear resistance and shock tolerance, which supports longer tool life under standard cutting conditions. Longer life reduces tooling consumption and contributes to lower process costs per hole. In addition, the consistent edge integrity helps to secure repeatable results part‑to‑part, a key factor for production environments where quality and throughput are equally important.

FAQ

What materials is this insert suitable for?
The P4840P-5R-A57 WKP25S insert is suitable for steel (P) and cast iron (K) applications, designed to handle the heat and chip behaviour typical of these material groups.

How does the Tiger‑tec Silver coating benefit machining?
The Tiger‑tec Silver coating on the WKP25S grade reduces friction and improves thermal stability, which helps maintain the cutting edge and extend insert life in drilling and boring operations.

Which geometry does the insert use and why does it matter?
The insert uses the 5R‑A57 geometry, which is engineered to promote controlled chip formation and secure chip evacuation, aiding stable machining performance in both steel and cast iron.

Is this insert compatible with standard drilling/boring indexable systems?
Yes, the insert is an indexable insert designed for drilling and boring systems; compatibility depends on the specific tool holder and insert seat, so matching the insert designation and geometry to the holder is recommended.
