P4840P-7R-E67 WKP35S — drill/boring indexable insert, Tiger·tec Silver, for steel and cast iron — Walter Tools

A P4840P-7R-E67 WKP35S drill/boring indexable insert designed for robust, productive machining of steel and cast iron in industrial drilling and boring applications

• Tiger·tec Silver for extended tool life
• WKP35S: high-performance coated carbide grade
• Optimised 7R-E67 chipbreaker for reliable chips
• Suited to steel and cast iron machining

Increase throughput with a coating engineered for endurance

The combination of the Tiger·tec Silver coating and the WKP35S grade delivers a measurable improvement in cutting-edge stability and wear resistance. This translates into longer tool life and fewer insert changes per shift, which improves process efficiency on the shop floor. The insert’s coated carbide construction is tailored to withstand the thermal and abrasive loads typical of machining steel and cast iron, so cycle times remain consistent and tool-change intervals are extended. For production environments where uptime and repeatability matter, this insert supports sustained high-performance drilling and boring.

Consistent chip control for safer, faster machining

The 7R-E67 chipbreaker geometry is optimised for predictable chip formation in both unalloyed and alloyed steels as well as cast irons. Predictable chips reduce the risk of jamming and make swarf handling more efficient, which in turn lowers downtime and improves operator safety. Thanks to the geometry and the coating’s friction characteristics, surface quality after drilling and boring is improved without compromising cutting speed. The result is a stable process that supports higher feed rates and consistent bore quality in medium-to-high volume production.

Practical advantages for the workshop and the production line

As an indexable insert intended for drilling and boring, this grade supports quick replacement and minimal setup effort, aiding repeatable quality across assemblies. The insert’s design focuses on reliable edge retention and stable chip formation, reducing the need for frequent regrinding or disposal. In addition to process benefits, operators and engineers gain clearer tool life forecasts and fewer unexpected stoppages, which simplifies planning and reduces overall machining cost per hole. The insert’s specification aligns with industrial requirements for robustness and predictability.
