P4841P-8R-A57 WKP35S Drill/reaming indexable insert, Tiger‑tec Silver — Walter Tools

The P4841P-8R-A57 WKP35S is an indexable insert designed for drilling and reaming applications, combining a coated‑carbide substrate with a specialised chipformer for machining steel and cast iron.

• Tiger·tec Silver coating for high process security
• WKP35S grade for steel and cast iron machining
• 8R‑A57 chipbreaker for controlled chip formation
• Suited for precision drilling and reaming operations

Increased productivity through wear‑resistant coating

The Tiger‑tec Silver coating on this insert significantly improves wear resistance and thermal stability compared with uncoated grades, which translates into longer tool life and fewer interruptions in production. As a result, machining cycles remain consistent for longer periods, reducing the frequency of tool changes and helping to maintain stable cycle times. The combination of a robust substrate and a specialised coating supports economic, continuous operation in demanding metalcutting tasks.

Reliable chip control for safer, cleaner machining

Thanks to the 8R‑A57 chipbreaker geometry, this insert offers predictable chip control when cutting both steel and cast iron. Controlled chips reduce the risk of built‑up edge and tangling, improve coolant access to the cutting zone and simplify swarf handling. The geometry is optimised to produce short, segmental chips on brittle materials and stable, controllable chips on ductile steels, which benefits process reliability and surface finish without the need for complex setup changes.

Grade and substrate engineered for mixed production

The WKP35S grade is a coated‑carbide formulation tuned for machining across ISO groups P and K. It balances toughness and hardness to resist both abrasive wear from cast components and thermal loading typical of steel machining. This makes the insert particularly useful in mixed‑batch production or in operations where tool life consistency is critical. The material pairing ensures repeatable performance and predictable regrinding or indexing intervals.

Geometry and handling suited to precision holemaking

Designed as a drill/reaming indexable insert, the part geometry supports precise holemaking and consistent concentricity in serial production. The cutting edge stability reduces radial deflection and contributes to better hole roundness and surface integrity. Integration into common drill or reamer bodies is straightforward, allowing fast replacement and minimal downtime during insertion changes. The insert’s design supports efficient clamping and repeatable location within toolholders.
