P4840P-3R-E67 WKP35S drilling/reaming indexable insert — Tiger·tec Silver coating, for steel & cast iron | Walter Tools

P4840P-3R-E67 WKP35S is a drilling/reaming indexable insert engineered for high-productivity machining of steel and cast iron

• Tiger·tec Silver coating for long tool life
• WKP35S grade optimised for steel and cast iron
• Stable chip formation under varied cutting conditions
• Compatible with P4840P-3R-E67 holder design

Extend uptime through advanced coating and grade selection

The combination of Tiger·tec Silver technology and the WKP35S grade provides a durable, coated carbide solution that reduces flank wear and maintains cutting-edge geometry over longer cycles. This translates into fewer tool changes and more consistent component tolerances, so production runs stay on schedule. The coating improves heat resistance and reduces built-up edge during interrupted cuts, supporting higher feed rates without sacrificing surface integrity.

Achieve reliable chip control for fewer interruptions

Equipped with the chipbreaker 3R-E67, this insert promotes stable chip formation when machining both steel and cast iron, minimising the risk of chip entanglement and workpiece damage. Predictable chips reduce the need for manual clearing and lower the likelihood of machine stoppages, contributing to smoother unmanned shifts and improved cycle times. The geometry is designed to handle the typical thermal and mechanical conditions encountered when cutting unalloyed and alloyed steels as well as grey and ductile cast irons.

Integrate easily and improve process security

The insert matches the P4840P-3R-E67 designation and fits established drilling and bore-enlarging tool systems, allowing straightforward replacement and compatibility with existing holders. For shops seeking higher consistency in serial production, the Tiger·tec Silver series offers repeatable performance and simplified grade selection. The design supports both roughing and semi-finish operations in mixed-material production, making it suitable for job shops and internal toolrooms that require a balance of productivity and predictable tool life.
