P4841C-8R-E57 WKP35S indexable insert for drilling and boring (steel, cast iron) – Walter Tools

The P4841C-8R-E57 WKP35S is an indexable insert engineered for high-productivity drilling and bore-enlargement in steel and cast iron, combining a durable coated carbide grade with a dedicated chipformer.

• Tiger·tec Silver coating for extended life
• Optimised chipbreaker 8R-E57 for reliable chips
• Suited for steel and cast iron machining

More throughput with advanced coating technology

The Tiger·tec Silver coating, paired with the WKP35S grade, reduces flank wear and improves thermal resistance, which translates into a longer tool life and fewer tool changes during batch production. This insert’s coated carbide composition is designed to withstand the heat and abrasive conditions typical of machining steel and cast iron, so production runs can be carried out with greater continuity and lower tooling overhead.

Consistent chip control for uninterrupted machining

The 8R-E57 chipbreaker geometry provides stable chip formation, preventing blockages and minimising machine downtime. By controlling chip flow reliably, swarf evacuation is improved and surface finish remains consistent, which supports higher feed rates and dependable cycle times. The result is reduced process interruptions and a predictable machining rhythm for metal-cutting operations.

Broad applicability across steel and cast-iron workpieces

Designed in accordance with ISO material groups, this insert is suitable for the P and K categories, making it a practical choice when machining both unalloyed and alloyed steel as well as cast iron. The wide material coverage reduces the need for multiple tool types, simplifying tool inventories and enabling flexible production scheduling without sacrificing performance.

Process security and repeatable results

Manufactured by a well‑established brand, the insert offers process reliability and reproducible results in series machining. The combination of a robust grade and a proven chipformer supports consistent dimensional accuracy and surface quality, helping to maintain component tolerances and reduce rework rates. Integration into existing toolholders and machining strategies is straightforward, allowing efficient adoption into standard workflows.
