P4840P-2R-A57 WKP35S — Drilling/boring indexable insert with Tiger‑tec Silver coating — Walter Tools

P4840P-2R-A57 WKP35S is a drilling/boring indexable insert optimised for high productivity machining of steel and cast iron in industrial applications

• Tiger·tec Silver coating for wear resistance
• Optimised 2R‑A57 chipbreaker for stable chips
• Designed for steel (P) and cast iron (K)
• High productivity for drilling and boring

Reliable performance for demanding drilling operations

The combination of the Tiger‑tec Silver coating and the WKP35S cutting grade delivers pronounced wear resistance and predictable flank‑wear behaviour in continuous production. The coated carbide substrate reduces adhesive wear and improves thermal stability, which translates into longer tool life and fewer index changes. For operations where uptime and repeatable results matter, this cutting grade supports higher cutting parameters without sacrificing component tolerances, helping to keep cycle times consistent and production costs under control.

Consistent chip control and improved surface quality

The integrated 2R‑A57 chipbreaker is engineered to produce short, controllable chips when machining steel and cast iron, reducing the risk of chip entanglement in through‑hole operations and improving evacuation. Stable chip control means fewer interruptions for cleaning and a more uniform contact at the cutting edge, which in turn helps to secure a better surface finish on the bore wall. For workshops targeting higher feeds and steady surface integrity, the insert geometry offers a clear technical advantage over standard grades.

Productivity-focused design with clear material scope

Specified for the ISO groups P and K (steel and cast iron) in accordance with material group classifications, the insert supports a broad range of common structural and grey/ductile cast materials. The grade and geometry are selected to balance cut‑edge robustness and economy of use, enabling fewer tool changes and predictable regrinds where applicable. The result is an insert that contributes to streamlined tool management and measurable improvements in throughput for drilling and enlarging operations.

FAQ

What materials is this insert suitable for?
The insert is specified for steel (ISO group P) and cast iron (ISO group K); the WKP35S grade and the Tiger‑tec Silver coating are tuned for these groups.

How does the 2R‑A57 chipbreaker improve machining?
The 2R‑A57 chipbreaker produces short, consistent chips during drilling and boring, improving evacuation and reducing the risk of chip interference with the cutting edge.

Can this insert be used for high‑feed drilling?
The combination of grade and geometry is designed for productive drilling; parameters should be chosen according to machine rigidity and workpiece specifics for optimal life.

Is the insert a standard indexable type compatible with common drill bodies?
The P4840P‑2R‑A57 form is a standard designation for indexable inserts used in drilling/boring tool systems; compatibility depends on the tool body and clamping geometry.
