P4840P-6R-E67 WKP35S indexable insert for drilling/reaming — Tiger‑tec Silver, Walter Tools

The P4840P-6R-E67 WKP35S is a precision indexable insert designed for high‑productivity drilling and reaming operations, optimised for machining steel and cast iron.

• Tiger‑tec Silver coating for long life
• WKP35S grade for steel and cast iron
• 6R‑E67 chipbreaker for reliable chip control
• Coated carbide for stable cutting edges

Greater productivity through predictable tool life

The Tiger‑tec Silver series offers a balanced coating system that reduces flank and crater wear, resulting in longer tool life and fewer insert changes. The WKP35S coating grade is a coated carbide specification tuned for the thermal and abrasive conditions encountered when machining ISO group P (steel) and K (cast iron) materials. By combining a robust substrate with an advanced coating, the insert reduces downtime and increases machining throughput, which translates into measurable improvements in overall process efficiency.

Clean chip control and surface consistency

The 6R‑E67 chipbreaker geometry is engineered to form short, controllable chips during drilling and reaming, lowering the risk of chip entanglement and improving coolant flow. Effective chip control helps maintain a consistent cutting zone, which supports a stable cutting edge and a reliable surface finish. For workshop planners and production engineers, this means fewer interruptions, more consistent part quality and a reduced need for secondary operations to rework surfaces.

Application support and integration into existing tooling

This insert is suitable for a wide range of catalogue‑dependent drilling and bore‑enlarging toolholders and is particularly effective when paired with tool bodies compatible with Walter Tools insert styles. The grade WKP35S is optimised for general steel and cast iron applications and tolerates the typical heat and chip formation characteristics of these materials. For integration into specific tool setups, Metav Werkzeuge provides technical advice and application tables to match insert geometry, cutting data and clamping systems for reliable performance.
