P4840P-3R-E57 WKP35S drilling/boring indexable insert – Walter Tools

The P4840P-3R-E57 WKP35S is an indexable insert engineered for drilling and enlarging operations, optimised for steel and cast iron applications and delivered in the Tiger·tec Silver series.

• Tiger·tec Silver coating for improved wear resistance
• WKP35S coated carbide for consistent tool life
• Optimised chipformer for stable chip control

Higher throughput thanks to proven coating and grade

The Tiger·tec Silver technology combined with the WKP35S grade provides enhanced wear resistance and consistent edge stability under the heat and mechanical load typical of steel and cast iron machining. This coated carbide formulation reduces flank and crater wear, which in turn supports predictable tool life and fewer index changes. For production environments this translates into measurable improvements in uptime and process reliability, since the insert maintains its cutting geometry longer under comparable cutting conditions.

Reliable chip control and process security for drilling operations

Designed with the 3R‑E57 chipformer, this indexable solution offers stable chip formation and reliable evacuation during through-hole and enlarging cycles. The geometry promotes short, controllable chips in cast iron and the typical continuous or segmented chips encountered in steel, supporting consistent surface finish and minimised rework. Integration into existing toolholders is straightforward thanks to the standard designation, offering a rapid route to improved cycle times and process security without major fixture changes.

Practical selection and handling benefits for workshop use

As a series member of Tiger·tec Silver, the insert is suited to the ISO material groups P (steel) and K (cast iron), which simplifies grade selection for mixed-production environments. The robust substrate and coating combination reduces the risk of premature edge breakdown when machining abrasive cast materials or when encountering intermittent contact in drilling. For teams seeking a balance of economy and performance, the grade's behaviour supports repeatable results and easier tool management, cutting down on unplanned stoppages and inspection needs.

FAQ

What materials is this insert intended for?
The P4840P-3R-E57 WKP35S insert is intended for steel (P) and cast iron (K) applications, reflecting the Tiger·tec Silver grade’s optimised wear behaviour.

How does the Tiger·tec Silver coating improve performance?
Tiger·tec Silver increases thermal and abrasive resistance for the WKP35S grade, helping the insert retain cutting-edge integrity and deliver consistent tool life under demanding drilling conditions.

What role does the 3R‑E57 chipformer play?
The 3R‑E57 chipformer governs chip geometry to ensure stable evacuation and reduced chip-related disturbances during drilling and enlarging operations, improving surface finish and process security.

Is this insert compatible with standard drilling indexable holders?
The designation and form follow common industry standards for drilling/boring indexable inserts, allowing integration with compatible holders designed for the P4840P-3R-E57 series.

When is WKP35S the recommended grade?
WKP35S is recommended where a coated carbide grade is needed to handle the thermal loads and varied chipbreaking characteristics of both steel and cast iron in medium to high production environments.
