Bohr-/Aufbohrwendeschneidplatte P4840C-1R-E67 WKP35S – Tiger‑tec Silver coated drill/boring indexable insert by Walter Tools

Bohr-/Aufbohrwendeschneidplatte P4840C-1R-E67 WKP35S is a coated indexable insert developed for drilling and boring applications in steel and cast iron, offering a reliable cutting edge and predictable tool life

• Tiger‑tec Silver coated carbide
• Optimised for steel and cast iron
• ISO designation P4840C-1R-E67
• Suitable for drilling and boring

Consistent cutting performance for mixed production

The insert delivers repeatable machining results in serial and batch production thanks to the WKP35S grade, a coated carbide developed for the thermal and abrasive demands of steel and cast iron. The combination of a robust substrate and the Tiger‑tec Silver technology provides improved heat management and reduced flank wear, which translates into longer intervals between indexings and more predictable maintenance cycles. This reliability supports production planning and reduces unscheduled downtime in machining centres.

Efficient machining through optimised chip control

The 1R‑E67 chipbreaker geometry is designed to promote controlled chip formation during drilling and boring operations. For operations in accordance with ISO 513 material groups P (steel) and K (cast iron), the geometry encourages short, consistent chips, reducing the risk of chip entanglement and improving surface finish. The insert’s behaviour under load helps maintain feed and speed parameters, enabling higher metal removal rates while preserving component quality — a rational advantage for productivity-focused shops.

Broad applicability and process security

Belonging to the Tiger‑tec Silver series, the insert is suited to a wide range of steels and cast irons encountered in general engineering and component manufacture. The coated grade supports both roughing and semi‑finishing operations where edge stability and wear resistance are decisive. By combining a modern coating system with a reliable substrate, the design addresses common machining challenges such as thermal softening and abrasive wear, offering a balance between cutting performance and tool life that benefits cost‑effective production.

FAQ

What materials is this insert suitable for? The P4840C-1R-E67 WKP35S insert is specified for machining steel (ISO group P) and cast iron (ISO group K), utilising the Tiger‑tec Silver coating for improved wear resistance.

Which operations match the geometry 1R‑E67? The 1R‑E67 geometry is tailored for drilling and boring operations where controlled chip formation and consistent feeds are required; it supports both roughing and semi‑finishing passes with the WKP35S grade.

How does Tiger‑tec Silver benefit machining performance? Tiger‑tec Silver provides enhanced heat control and a durable coating layer that reduces flank wear, giving the WKP35S grade a longer useful life and more predictable tool changes.

Is this insert compatible with standard toolholders for indexable drill systems? The insert follows the ISO designation P4840C-1R-E67 and can be used in compatible indexable drill and boring tool systems designed for that insert form and size.

What is the expected advantage in production environments? Using the WKP35S Tiger‑tec Silver insert typically improves process stability and reduces unplanned tool interventions, supporting continuous production and consistent part quality.
