P4840C-7R-F57 WKP35S Drill / boring indexable insert — Tiger‑tec Silver, for steel and cast iron — Walter Tools

P4840C-7R-F57 WKP35S is an indexable insert designed for drilling and boring operations, optimised to deliver reliable cutting performance in steel (P) and cast iron (K) applications, especially where process stability and predictable wear behaviour are required.

• Tiger‑tec Silver coating performance
• WKP35S grade for steel and cast iron
• Optimised chipformer 7R‑F57
• High tool life and stable cutting edge

Consistent cutting results through advanced coating and grade

The insert combines the Tiger‑tec Silver coating with the WKP35S coated-carbide grade to provide enhanced wear resistance and thermal stability during interrupted and continuous cuts. This combination is especially beneficial when machining unalloyed and alloyed steel as well as cast iron, where heat and abrasive wear are common. The coated carbide matrix reduces flank wear and maintains a sharper edge for longer, which translates into fewer tool changes and more predictable cycle times. Where surface finish and dimensional repeatability matter, the improved edge stability contributes directly to reduced rework and higher first-pass yield.

Better chip control and lower process risk with the 7R‑F57 chipformer

Equipped with the 7R‑F57 chipbreaker geometry, the insert delivers controlled chip formation that reduces the risk of entangling or long stringy chips in drilling and boring operations. Optimised chip evacuation leads to lower heat accumulation at the cutting zone and supports consistent material removal rates. For operations that require unattended shifts or high-volume production, the improved chip flow reduces interruptions and the likelihood of tool‑related scrap. The geometric design also aids coolant penetration and helps maintain surface integrity, supporting a cleaner machining environment and less post-process cleaning.

Production benefits: fewer tool changes, higher uptime

The insert’s application focus on steel and cast iron makes it a versatile choice across many production tasks, enabling standardisation of tooling across multiple part families. The robust grade and coating reduce wear-related downtime and support higher cutting parameters where appropriate, improving overall equipment effectiveness. Integration into existing toolholders is straightforward, offering a cost-effective route to improved process security without extensive tooling redesign. For decisions on optimal cutting data and holder compatibility, Metav Werkzeuge can provide tailored advice and machining data to match specific setups and productivity goals.
