P4840P-2R-E57 WKP35S – Indexable Drill/Reamer Insert, Tiger‑tec Silver (Walter Tools) for Steel & Cast Iron

A high-performance P4840P-2R-E57 WKP35S indexable insert engineered for drilling and reaming applications, optimised for reliable performance in steel and cast iron components.

• Tiger‑tec Silver coated carbide
• Optimised for steel and cast iron
• Stable cutting edge and wear resistance
• Geometry 2R‑E57 for controlled chip formation

Improved process stability for demanding production

The Tiger‑tec Silver coating combined with the WKP35S grade offers a balance of hardness and toughness that translates into improved wear resistance under typical turning and drilling loads. Coated cemented carbide technology reduces flank wear and maintains a stable cutting edge, so machining cycles remain predictable across production runs. This stability supports higher uptime and contributes to consistent part quality without frequent tool changes.

Predictable chip control and surface finish

The insert’s 2R‑E57 chipbreaker geometry is designed to direct and break chips efficiently during drilling and reaming operations. Controlled chip formation reduces the risk of entanglement and tool interruption, which in turn helps maintain a reliable surface quality on workpieces. For workshops aiming to lower scrap rates and rework, the predictable behaviour of the chipbreaker provides a measurable benefit in throughput and process reliability.

Broad suitability across steel and cast iron applications

The grade is optimised for ISO groups P (steel) and K (cast iron), meaning it is formulated to cope with the heat and material behaviour typical of these groups. In practical terms, the insert performs well on unalloyed and alloyed steels as well as abrasive cast-iron variants, offering versatility for mixed-production environments. The clear designation for steel and cast iron simplifies tool selection and helps ensure the right grade is used for the correct material class.

Operational benefits that matter on the shop floor

By combining a wear-resistant coating with a geometry tailored for chip control, the insert supports higher productivity through longer intervals between indexing and predictable tool life. Fewer process disruptions and stable machining parameters reduce the need for constant readjustment, making planning and scheduling more efficient. The robust design also aligns with standard indexable tool systems, allowing straightforward integration into existing toolsets.
