Drill/Boring indexable insert P4160-2R04-E47 WKK20S — Tiger‑tec Silver coated carbide for cast iron (Walter Tools)

The P4160-2R04-E47 WKK20S is a drill/boring indexable insert engineered for efficient machining of cast iron, combining Tiger‑tec Silver coating with a purpose-designed chipbreaker to maintain process stability in abrasive materials

• Tiger‑tec Silver coated carbide grade WKK20S
• Optimised for abrasive cast iron machining
• Stable chip formation for consistent productivity
• Compatible with P4160-2R04-E47 insert geometry

Improved process reliability through a high‑performance coating

The combination of the Tiger‑tec Silver coating and the WKK20S carbide grade provides a measured increase in wear resistance for abrasive cast iron applications. Coated cemented carbide minimises flank and crater wear under typical interrupted-cut conditions, which translates into longer tool life and fewer index changes on the shop floor. Because the grade is designed for the ISO K group, the insert copes well with the short, brittle chips and abrasive particle content commonly found in cast iron, giving predictable service intervals and helping to reduce unplanned production stops. These material and coating choices together support a more consistent surface finish and repeatable cycle times.

Predictable chip control reduces downtime and improves throughput

The integrated 2R04‑E47 chipbreaker is tuned to produce small, manageable chips during drilling and boring in cast iron, which reduces the risk of chip entanglement and machine stoppages. Stable chip formation directly affects spindle load and coolant flow, leading to smoother machining and reduced cleaning or manual intervention between cycles. For production environments where uptime and repeatability are paramount, the combination of chip geometry and coated carbide enables higher effective productivity without complex process changes. The result is a measurable reduction in machine idle time and a more reliable production flow.

Tailored for cast iron: clearer results with less rework

Designed for ISO group K materials, this insert addresses the specific challenges of abrasive cast iron cutting—namely rapid abrasive wear and fragmented chips. By matching coating technology and grade to the workpiece, the insert reduces the frequency of edge failure and contributes to improved surface quality on bores and countersinks. The technical design helps to avoid secondary operations caused by poor surface integrity, which is particularly important in assemblies where bore tolerance and finish matter. In short, the tool supports fewer corrective steps and steadier output quality.

Smooth integration into existing drilling and boring set-ups

The insert geometry and designation are compatible with standard P4160‑style toolholders, allowing for simple replacement and minimal set‑up changes. Because the component follows established insert standards, tool change routines and inventory management remain straightforward. The carbide backing and coated face allow secure clamping and consistent seating, which assists in maintaining tool runout and repeatability across successive inserts. For workshops seeking an efficient upgrade for cast iron operations, this insert delivers an immediate performance uplift with limited process adaptation.
