P4840P-3R-E67 WKP25S - Drilling/Boring Indexable Insert, Tiger·tec Silver (Walter Tools)

The P4840P-3R-E67 WKP25S is an indexable insert engineered for drilling and bore enlargement, optimised for use in steel and cast iron machining.

• Tiger·tec Silver coating for long life
• Optimised for steel and cast iron
• WKP25S coated carbide grade
• 3R-E67 chipbreaker for stable chips

Higher lifetime through advanced coating and grade

The combination of Tiger·tec Silver and the WKP25S coated carbide grade delivers enhanced wear resistance and thermal stability under the stresses of drilling and boring. The coated substrate reduces flank wear and protects the cutting edge during interrupted cuts common in holemaking. For traders and production planners, this means fewer tool changes and more predictable maintenance intervals, improving overall process reliability while retaining dimensional accuracy in serial production.

Reliable chip control for safer, faster machining

Equipped with the 3R-E67 chipbreaker geometry, the insert promotes stable chip formation, preventing long, stringy swarf and reducing the risk of re-cutting. The chipbreaker’s profile directs chips away from the cutting zone and tool shank, which helps maintain consistent cycle times and surface integrity in bores. Explaining briefly: a well-designed chipbreaker converts chips into short, manageable segments, which improves evacuation in deep holes and contributes directly to higher productivity and reduced machine downtime.

Practical integration and predictable performance on the shop floor

The ISO-style designation facilitates quick matching with compatible toolholders and drilling systems, simplifying inventory and tool management. As a drilling/boring indexable insert from Walter Tools’ Tiger·tec Silver series, this plate is intended primarily for the ISO P and K material groups—steel and cast iron—making it a versatile choice across common workshop applications. The clear material focus supports process planning: operators can expect consistent cutting behaviour on unalloyed and alloyed steels as well as on a range of cast-iron grades.

FAQ

What workpiece materials is this insert suitable for?
The insert is intended for ISO groups P and K, which covers a wide range of steel and cast iron machining tasks with the WKP25S grade.

Does the chipbreaker suit deep-hole drilling?
Yes, the 3R-E67 chipbreaker is designed to produce short chips and improve evacuation, which supports safer and more efficient deep-hole operations.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating increases thermal and abrasive resistance, extending tool life and maintaining cutting edge stability during high-load drilling and boring.

Can this insert be used for stainless applications?
This insert is specified for steel and cast iron; there is no explicit rating for stainless materials in the provided data, so stainless applications are outside the documented scope.
