P4841C-8R-A57 WKP35S drilling/reaming indexable insert by Walter Tools — Tiger·tec Silver, 8R-A57 chipbreaker

The P4841C-8R-A57 WKP35S is a drilling and reaming indexable insert engineered for high-productivity machining of steel and cast iron in industrial metalcutting applications

• Tiger·tec Silver coating for extended life
• Optimised 8R-A57 chipbreaker for controlled swarf
• Suited to steel and cast iron (ISO P / K)
• Robust grade WKP35S for industrial runs

Sustained productivity through advanced coating and grade

The combination of the Tiger·tec Silver coating with the WKP35S grade delivers a balance of wear resistance and toughness that supports longer tool life in repetitive operations. Coated carbide inserts use a hard, thin layer applied to a carbide substrate to resist abrasive wear and reduce thermal softening; this means fewer indexings and longer uninterrupted cycles in production. For shops machining ISO group P (steel) and K (cast iron), the result is a more predictable tool life and reduced tooling intervention, which translates into measurable gains in throughput and process reliability.

Stable chip formation for clean drilling and reaming cycles

The integrated 8R-A57 chipbreaker is designed to shape swarf consistently under the cutting conditions typical of drilling and reaming. Effective chip control reduces the risk of clogging, improves coolant access and supports consistent surface quality in the hole. Controlled chip flow prevents sudden load peaks on the tool and machine, enhancing process security and enabling higher metal removal rates with lower scrap risk. For engineers assessing cycle optimisation, improved chip management directly reduces machine downtime and rework.

Designed for dependable industrial use and straightforward integration

As an indexable insert for drilling and reaming applications, this geometry simplifies tool management: the insert locates accurately in a tool holder, is easy to replace or index, and provides repeatable positioning for serial production. The coated carbide composition is suitable for a wide range of steels and common casting alloys, offering a pragmatic compromise between toughness and hardness. For production planners, this means consistent hole quality, fewer tool changes and a reliable basis for process planning in machining cells and centres.
