P4840C-4R-E67 WKP35S — Drill/Reamer Indexable Insert for Steel and Cast Iron (Walter Tools)

The P4840C-4R-E67 WKP35S is a coated carbide indexable insert developed for drilling and reaming operations in steel and cast iron, offering high wear resistance and process reliability

• Tiger·tec Silver coating for extended tool life
• WKP35S grade optimised for steel and cast iron
• Geometry 4R‑E67 for controlled chip formation
• Compatible with P4840C‑4R‑E67 tool systems

Proven hardness and wear resistance for steady machining results

The combination of a coated carbide substrate and the Tiger·tec Silver coating delivers significantly improved wear resistance compared with uncoated grades. That enhanced durability supports longer tool life and more consistent component quality in production environments where thermal and abrasive loads vary. The grade WKP35S is formulated for the specific chip behaviour and heat development encountered when machining both steel (ISO group P) and cast iron (ISO group K), making it a reliable choice for mixed production runs and jobbing operations.

Geometry designed to control chips and boost productivity

The insert's 4R‑E67 geometry is engineered for steady chip breaking and predictable evacuation. Controlled chip formation reduces the risk of entanglement, lowers tool‑holder loads and helps maintain a stable process window during through‑hole drilling or reaming passes. The result is improved productivity through fewer interruptions, reduced tool changes and a consistent surface finish, particularly important in serial production and parts with tight tolerances.

Integration into machining processes and selection advice

As an indexable insert for drill/reamer systems, the P4840C‑4R‑E67 WKP35S is intended for straightforward integration into existing toolholders that accept the P4840C geometry. The coated carbide chemistry and the insert geometry support high feed and moderate cutting speeds where the balance of tool life and cycle time is required. For application matching, process planners often compare material group, required surface quality and cycle time to confirm the best grade; technical spreadsheets and machining data sheets can be provided on request to aid decision making.
