P4840P-4R-E67 WKP25S Drilling/Boring indexable insert — for steel and cast iron | Walter Tools

The P4840P-4R-E67 WKP25S is a drilling/boring indexable insert engineered for productive metalcutting in mixed production environments, especially for steel and cast iron components.

• Tiger·tec Silver coating technology
• WKP25S coated cemented carbide grade
• Optimised 4R‑E67 chipbreaker geometry
• For steel and cast iron applications

Consistent productivity through advanced grade and coating

The combination of the WKP25S coated cemented carbide grade and the Tiger·tec Silver coating provides a reliable, high-performance cutting edge that keeps production stable. The coating reduces friction and thermal impact during drilling and boring, which helps to extend tool life and reduce downtime. For operations that demand repeatable cycle times and predictable wear, this indexable insert offers an economical balance between longevity and cutting efficiency, reducing the frequency of index changes and maintaining throughput.

Better chip control and surface quality with optimised geometry

The integrated 4R‑E67 chipbreaker is designed for reliable chip formation when machining both steel and cast iron, minimising built-up edge and erratic chip behaviour. Improved chip control translates into fewer interruptions and a cleaner hole or bore finish, which is particularly important in batch production and automated machining centres. The insert’s geometry supports consistent cutting forces, aiding in achieving stable surface quality while lowering the risk of tool-related rework.

Versatile use in mixed-material production

Designed for compatibility with ISO groups P and K, the insert suits a broad range of components found in general engineering and automotive applications. The grade and geometry combination enables productive turning of unalloyed and alloyed steels as well as abrasive cast irons, making the insert a practical choice where tool rationalisation and process flexibility are priorities. The indexable insert concept allows quick orientation changes at the toolholder, helping to shorten machine downtime during index changes.
