P2841S-3N-A57 WKP35S drilling/boring indexable insert — Walter Tools, Tiger·tec Silver, for steel and cast iron

The P2841S-3N-A57 WKP35S drilling/boring indexable insert is a coated cemented carbide grade from the Tiger·tec Silver series, designed for productive machining of steel and cast iron with a dedicated 3N‑A57 chipbreaker.

• Tiger·tec Silver coated carbide grade
• Optimised for steel and cast iron machining
• Stable chip formation and abrasive wear resistance
• Consistent tool life and process reliability

High-performance coating that reduces wear and keeps cycles running

The Tiger·tec Silver coating combined with the WKP35S grade provides a balance between abrasion resistance and toughness, which is essential for continuous drilling and boring cycles. The layered coating reduces flank and crater wear under typical steel and cast‑iron cutting temperatures, leading to extended intervals between index changes. This technical advantage translates directly into fewer interruptions on the shop floor and more predictable tool life, supporting tighter production planning and lower per‑hole costs.

Optimised geometry for controlled chip formation in P and K materials

With the 3N‑A57 chipbreaker geometry, the insert delivers consistent chip control when machining both unalloyed and alloyed steel (P) and abrasive cast iron (K). The chipbreaker is engineered to produce short, manageable chips on interrupted or continuous cuts, reducing the risk of chip entanglement and improving surface integrity. For engineers assessing tooling options, the combination of chip control and coated carbide ensures process stability across typical ISO 513 workpiece classes.

Productivity gains through repeatable performance and fewer tool changes

The coated cemented carbide construction of this insert emphasises repeatable performance: predictable wear patterns allow for reliable change intervals and less unplanned downtime. In production environments where cycle time and first‑pass accuracy matter, the insert’s wear resistance contributes to consistent hole quality and reduced rework. When paired with suitable toolholders and correct cutting parameters, the result is higher throughput with maintained surface finish standards.

Practical guidance for selection and integration in machining setups

Selection of the P2841S‑3N‑A57 geometry should follow the workpiece material and cutting data: choose the WKP35S grade for mixed production of steel and cast iron where process reliability and tool life are priorities. The insert is intended for standard drilling and boring applications; matching insert seat and clamping system is essential to exploit the coating and chipbreaker benefits.
