P4840P-1R-E67 WKP25S — Drilling/Boring Indexable Insert, Tiger‑tec Silver (Walter Tools)

The P4840P-1R-E67 WKP25S is a drilling and boring indexable insert engineered for efficient machining of steel and cast iron in production environments

• Tiger‑tec Silver coated grade WKP25S
• Designed for steel and cast iron machining
• Chipbreaker 1R‑E67 for stable chip control
• Coated carbide for extended edge life

Consistent productivity through enhanced edge life

The combination of the Tiger‑tec Silver coating and the WKP25S grade delivers significantly improved wear resistance compared with uncoated grades, which translates into longer service intervals and fewer tool changes. This means more productive cutting cycles and a lower incidence of unscheduled stoppages. Coated carbide provides thermal and abrasive protection that maintains the cutting edge under typical steel and cast iron cutting conditions, so operators benefit from predictable tool life and reduced setup frequency.

Predictable chip control reduces rework and cycle time

The 1R‑E67 chipbreaker geometry is developed for consistent chip formation when turning and boring typical steels and cast iron, reducing the risk of built-up edge and uncontrolled chips. Predictable chips improve evacuation and lower the probability of surface damage, which in turn reduces secondary operations and quality-related rework. Good chip control also supports safer automated processes and steadier cutting forces, contributing directly to reliable cycle times on both single machines and production lines.

Broad material range for flexible job planning

Designed for ISO material groups P (steel) and K (cast iron), this insert supports a wide range of production tasks without frequent tool swaps. The coated carbide chemistry and the Tiger‑tec Silver technology are optimised for the heat and abrasion characteristics typical of these materials, enabling a single insert type to cover multiple workpieces and geometries. For shops with mixed batches, this flexibility simplifies inventory and speeds up job changes while maintaining surface quality and dimensional stability.

Straightforward integration into tool systems for fast adoption

The designation and geometry align with common drilling and boring tool-holder standards, facilitating fast installation into existing tool systems and reducing downtime during tool changes. The P4840P-1R-E67 form factor is suitable for conventional indexable tool assemblies, making it simple to standardise the cutting edge across tools. The result is easier tool management, quicker operator familiarisation and seamless adoption in production without extensive machine modifications.

FAQ

What materials is this insert suitable for?
The insert is optimised for steel and cast iron applications; the WKP25S grade and Tiger‑tec Silver coating are developed for these ISO material groups.

How does the 1R‑E67 chipbreaker help in production?
The 1R‑E67 geometry provides controlled chip formation for stable machining, improving chip evacuation and lowering the risk of surface damage and rework.

Is this insert a coated or uncoated grade?
This is a coated carbide insert using the Tiger‑tec Silver technology for enhanced wear resistance and thermal protection.

Will the insert decrease tool-change frequency?
Due to the improved edge life of the WKP25S grade, tool-change intervals are extended compared with less wear‑resistant grades, supporting longer uninterrupted production runs.
