P4840P-7R-E57 WKP35S indexable insert for drilling and boring by Walter Tools

P4840P-7R-E57 WKP35S is an indexable insert designed for drilling and bore-enlarging applications, optimised for machining steel and cast iron with high process stability

• Tiger·tec Silver coating for wear resistance
• WKP35S coated carbide grade for broad material range
• Suitable for steel (P) and cast iron (K) machining
• Chipbreaker 7R-E57 for consistent chip control

Faster, more predictable results in steel and cast-iron machining

The Tiger·tec Silver coating together with the WKP35S grade provides a blend of wear resistance and toughness that is particularly suited to the heat and chip formation typical of machining steel and cast iron. The combination of a coated carbide substrate and a specialised surface treatment reduces abrasive wear and delays flank degradation, which translates into fewer tool changes and steadier cycle times. For operations where repeatability and run-time economy matter, this insert supports reliable throughput while maintaining acceptable surface quality on bores.

Controlled chips and longer cutting intervals for fewer interruptions

Equipped with the 7R-E57 chipbreaker, the insert promotes short, regular chips and improved evacuation from the cutting zone. The defined chip geometry lowers the risk of clogging and reduces vibration during drilling and boring, leading to a more consistent surface finish and fewer micro interruptions in production. Explanation for less technical readers: the chipbreaker shapes how the metal swarf breaks away, so reliable chip control means safer machining, fewer reworks and less unplanned downtime—factors that benefit both manual and automated drilling systems.

Easy integration into production workflows and tool systems

The insert’s designation and geometry ensure compatibility with common drilling and boring toolholders used in high-productivity environments. Its coated carbide construction and application range for steel (P) and cast iron (K) make it a versatile choice for job shops and production facilities seeking to reduce inventory complexity while keeping process stability high.
