P4841C-1R-A57 WKP35S drilling/reaming indexable insert – for steel & cast iron, Walter Tools

The P4841C-1R-A57 WKP35S is a drilling/reaming indexable insert engineered for precision machining operations in steel and cast iron, offering robust wear behaviour and predictable tool life.

• Tiger·tec Silver coating for enhanced wear resistance
• Designed for steel and cast iron machining
• Grade WKP35S coated carbide substrate
• 1R‑A57 chipbreaker for stable chip control

Consistent productivity through optimised coating and grade

The combination of the Tiger·tec Silver coating and the WKP35S grade provides a measurable improvement in wear resistance and edge stability during drilling and reaming. This results in fewer tool changes and longer uninterrupted runs, which directly supports higher component throughput and reduced cycle-time variability. The coated carbide substrate is designed to withstand the thermal and mechanical stresses typical of steel and cast-iron cutting, so the insert contributes to a more predictable production rhythm and lower overall tooling consumption.

Clear compatibility with materials and chip behaviour

This insert is specified for the ISO groups P and K, meaning it is suited to machining steel (P) and cast iron (K). The geometry and the 1R‑A57 chipbreaker are chosen to manage the typical chip shapes and breaking behaviour encountered in these materials, improving evacuation and reducing the risk of chip jamming. Where catalogue or machine geometry dictates, the insert’s benefits are most apparent in operations that require reliable chip control and consistent hole quality for finishing or near‑finishing passes.

Coating technology explained for better tool selection

The Tiger·tec Silver technology denotes a high-performance coated carbide system that balances adhesion, hardness and thermal stability to slow flank and crater wear. For users selecting tooling for mixed-production environments, the coating’s design reduces flank wear rates on interrupted cuts and high cutting-speed operations, preserving edge geometry for longer. Choosing a coated carbide grade such as WKP35S helps maintain surface integrity of the workpiece and reduces rework, which is especially relevant for serial drilling and bore enlargement tasks.

Operational advantages and process security

With the 1R‑A57 chipbreaker and the insert’s intended grade, the main operational benefits are improved process security and simpler tool management. The geometry supports steady chip formation, minimises unexpected tool failures and helps achieve consistent hole tolerances. For production planners, this means easier planning of tool change intervals and more stable cycle times; for machine operators, it means less intervention and clearer signals when an insert requires replacement.
