P4840P-8R-A57 WKP35S drill/boring indexable insert — Tiger·tec Silver coating, for steel and cast iron — Walter Tools

The P4840P-8R-A57 WKP35S is a drill/boring indexable insert designed to provide productive, repeatable machining performance when working on steel and cast iron components.

• Tiger·tec Silver coating for long tool life
• WKP35S grade for robust, consistent performance
• Chipbreaker 8R-A57 optimises chip control
• Suited to steel (P) and cast iron (K)

Increased productivity through advanced coating and grade

The combination of Tiger·tec Silver surface technology and a coated carbide substrate offers a measurable advantage in continuous machining tasks. This configuration reduces flank and crater wear, which translates into longer service intervals and fewer tool changes. The WKP35S grade is tailored to typical steel and cast-iron cutting conditions, providing stable cutting-edge behaviour and predictable tool life. For contract manufacturers and job shops, these improvements reduce non-productive time and help maintain throughput targets without compromising component tolerances.

Consistent chip control for uninterrupted machining

A decisive process advantage is achieved through the 8R-A57 chipbreaker geometry that promotes short, controllable chips during drilling and boring operations. Improved chip formation lowers the risk of rework and machine stoppages caused by chip evacuation issues. The insert’s geometry works in concert with the coated surface to keep temperatures and friction in check, supporting a stable cutting process. As a result, surface quality and dimensional consistency are improved, which benefits downstream operations such as honing or inspection.

Broad application scope with predictable performance

Designed principally for the ISO material groups P and K, this insert is effective across a wide range of unalloyed and alloyed steels as well as various cast-iron grades. The design emphasises process security: repeatable engagement angles, consistent wear progression and reliable edge stability. Those looking for dependable batch-to-batch results will appreciate the balance between wear resistance and toughness that the Walter Tools grade delivers. For production planning, this means fewer tool variants are required and setups can be standardised across similar machining tasks.
