Drill/reaming indexable insert P4840P-6R-F57 WKP35S — Tiger‑tec Silver, Walter Tools

The P4840P-6R-F57 WKP35S is a coated carbide indexable insert designed for drilling and reaming operations in steel and cast iron, offering enhanced wear resistance and reliable chip control for productive machining.

• Tiger‑tec Silver coating for long tool life
• Engineered for steel (P) and cast iron (K)
• Geometry 6R‑F57 for reliable chip control
• WKP35S grade for stable, repeatable cutting performance

Prolonged service life through advanced coating

The insert is equipped with the Tiger‑tec Silver technology and the WKP35S grade, a coated carbide composition engineered for higher thermal resistance and reduced abrasive wear. This results in a measurable extension of cutting edge life under the thermal and mechanical loads typical for machining steel and cast iron. The coating reduces flank wear and contributes to consistent dimensional stability, which in turn minimises machine downtime and tool change frequency — a direct benefit for production efficiency.

Predictable chip formation and geometry-focused performance

The 6R‑F57 chipbreaker geometry is optimised to control the chip flow and breakage tendencies specific to P- and K‑group materials according to ISO 513. Controlled chip formation lowers the risk of built-up edge and improves evacuation in through‑hole and blind‑hole operations, supporting consistent surface quality and fewer interruptions. The geometry's focus on chip control translates into more stable cutting forces and predictable tool behaviour, which assists process planners in defining reliable feeds and speeds.

Integration into machining processes for better throughput

As a drilling/reaming indexable insert from Walter Tools, the part is intended for straightforward integration into compatible tool bodies and drilling systems. The combination of grade, coating and chipbreaker supports higher material removal rates with maintained surface finish, helping to increase overall productivity. For job shops and production lines aiming for repeatability, the insert offers a balance of wear resistance and toughness that supports longer service intervals and fewer unscheduled tool swaps.

FAQ

What materials is this insert suitable for?
The P4840P‑6R‑F57 WKP35S insert is specified for machining steel (P) and cast iron (K) according to the ISO material group designations; the grade and coating are selected to handle the thermal and abrasive conditions typical for these groups.

What does the Tiger‑tec Silver series provide?
Tiger‑tec Silver is a multilayer coating technology that enhances thermal stability and wear resistance; in the WKP35S grade it helps to maintain edge integrity during elevated cutting temperatures and extends usable tool life.

How does the 6R‑F57 chipbreaker improve processes?
The 6R‑F57 geometry promotes controlled chip formation and breakage for drilling and reaming tasks, reducing the likelihood of long, stringy chips and aiding reliable chip evacuation — this supports consistent surface finish and fewer process interruptions.

Is this insert intended for stainless steel applications?
Stainless steel is not listed among the specified material groups for this insert; the P4840P‑6R‑F57 WKP35S is optimised for steel and cast iron. For austenitic or other stainless‑grade materials, a different grade or geometry may be preferable.

How to confirm compatibility with a specific tool holder or drill body?
Compatibility depends on the tool holder system and the insert pocket geometry; the ISO designation P4840P‑6R‑F57 WKP35S should be checked against the holder specifications to ensure fit and correct seating.
