P4840C-3R-E67 WKP35S drill/boring indexable insert, Tiger‑tec Silver – Walter Tools

The P4840C-3R-E67 WKP35S is an indexable cutting insert for drilling and boring, engineered for productive machining of steel and cast iron components.

• Tiger‑tec Silver coating for extended tool life
• Optimised chip control with 3R‑E67 chipbreaker
• Suited for steel (P) and cast iron (K)
• Coated carbide grade WKP35S for stable cutting

Increased productivity through advanced coating and grade

The combination of the Tiger‑tec Silver coating with the WKP35S grade delivers measurable gains in tool life and process stability. The coating reduces flank wear under the typical temperatures encountered when machining steel and cast iron, while the substrate provides a stable cutting edge that tolerates interrupted cuts and varying feed rates. For production environments this translates into fewer indexings, less downtime for tool change and a higher net output per tool body. The result is a favourable cost-per-part ratio without compromising surface quality or dimensional repeatability.

Predictable chip control and improved surface finish

The dedicated 3R‑E67 chipbreaker geometry guides chips away from the cutting zone, reducing the risk of rework from chip entanglement and minimising vibration during drilling and boring cycles. Controlled chip formation supports consistent coolant delivery and helps to maintain cutting temperatures within an optimal window. Operators observing the difference will note fewer build-ups on the flute and a more consistent bore finish, which benefits downstream processes such as honing or assembly. In short, the insert’s geometry directly supports stable machining and process reproducibility.

Broad material range and application flexibility

Designed for the ISO groups P (steel) and K (cast iron), this indexable insert covers a wide spectrum of common workshop and production tasks from general drilling to bore enlarging operations. The coated carbide composition suits both continuous and intermittent cutting conditions, making it appropriate for job-shop workloads and series production. For users requiring application guidance, the combination of grade and chipbreaker makes the insert a reliable baseline choice for mixed-component production where changeovers between steel and cast iron occur frequently.
