P2840S-3N-F57 WKP35S drilling/boring indexable insert with Tiger·tec Silver coating — Walter Tools

The P2840S-3N-F57 WKP35S is a coated carbide indexable insert designed for drilling and boring operations, engineered specifically for machining steel and cast iron in demanding industrial applications.

• Tiger·tec Silver coating for higher wear resistance
• WKP35S grade for stable cutting performance
• 3N-F57 chipbreaker for reliable chip control
• Optimised for steel and cast iron machining

Longer tool life through advanced coating technology

The combination of the Tiger·tec Silver coating and the WKP35S coated carbide substrate reduces flank and crater wear under thermal load, resulting in longer service intervals and fewer index changes. For shops running high-volume drilling cycles, this means less downtime and greater throughput. The coating lowers friction at the cutting edge, which permits steady cutting at elevated speeds while maintaining dimensional stability of the bore.

Predictable chip formation and process security

Equipped with the 3N-F57 chipbreaker, the insert produces short, controllable chips that evacuate reliably from the cutting zone during deep-hole drilling and boring. Stable chip control minimises tool interruptions and reduces the risk of workpiece surface damage, improving cycle-time consistency. This predictable behaviour supports automated processes and contributes to enhanced process security on CNC drilling rigs and gang-tool heads.

Broad material suitability for mixed-production environments

Developed for the ISO material groups P (steel) and K (cast iron), the grade is tuned to the thermal and abrasive characteristics of these workpiece families. The carbide substrate and coating balance toughness and hardness to withstand interrupted cuts and cast-iron abrasiveness, offering a single solution for mixed-production lines that would otherwise require multiple tool variants.

Practical benefits for workshop productivity

As an indexable solution, the insert reduces inventory complexity and machining cost per hole: the ability to rotate to fresh cutting edges extends usable life while simplifying logistics. The insert’s geometry supports stable cutting forces and helps to maintain surface finish and bore tolerances across production runs, translating into fewer reworks and a more predictable output rate for high-mix, low-to-medium-volume shops.
