P4840P-1R-A57 WKP35S — Drill/boring indexable insert by Walter Tools (for steel and cast iron)

A P4840P-1R-A57 WKP35S drill/boring indexable insert designed for robust, repeatable metal‑removal in the machining of steel and cast iron.

• Tiger·tec Silver coating for wear resistance
• Optimised chipformer 1R-A57
• Suited for steel and cast iron machining
• Coated carbide grade WKP35S

Longer production runs with reduced tool changes

The insert’s combination of the WKP35S grade and Tiger·tec Silver coating provides enhanced wear resistance and thermal stability, which directly reduces tool-change frequency and unplanned downtime. In practice, this means a lower cost per component and steadier process output. The coated carbide substrate is engineered to withstand the typical heat and abrasion encountered when turning and drilling ISO P and K groups, so the cutting edge retains geometry longer under continuous cycle times.

Reliable chip control for demanding materials

The chipformer 1R-A57 geometry is optimised for predictable chip breaking when working with steel and cast iron. This feature improves swarf evacuation and decreases the risk of re-cutting chips, which helps maintain surface quality and extends tool life. For users less familiar with chipformer terminology: the chipformer is the insert’s flank shaping that controls how chips curl and break; good chip control leads to safer machining and fewer interrupted cycles.

Consistent surface finish and process security

The insert’s stable cutting edge geometry supports a repeatable surface finish and dimensional consistency across production batches. Built for industrial environments, the design contributes to high productivity and reliable cycle times—critical for series production where process security is paramount. The combination of geometry and coating also assists with heat dispersion at the cutting zone, reducing flank wear and preserving the profile of the cutting edge.

Efficient handling and economical machining

Indexable inserts of this type allow rapid replacement and minimal set-up time, supporting lean workflows and flexible production schedules. The insert is compatible with standard drill and boring toolholders that accept the specified designation, enabling quick integration into existing tooling systems. By reducing non-productive time and extending effective cutting life, the overall machining cost per part is lowered, supporting competitive manufacturing.
