• Suitable for steel and cast iron machining

Maximise uptime with robust coating and grade

The combination of the Tiger·tec Silver coating and the WKP35S grade provides a clear production advantage: reduced wear and longer intervals between indexing or replacement. The coating technology improves thermal stability and adhesion, which slows flank and crater wear during continuous holemaking. For shops machining both low‑ and medium‑alloy components, this translates into fewer tool changes and predictable lifecycle behaviour. The result is consistent component tolerances and lower per‑hole tooling cost thanks to the insert’s engineered resistance to abrasive and adhesive wear.

Controlled chips for safer, faster holemaking

The chipbreaker 4N‑F57 geometry is designed to break and evacuate chips efficiently in drilling and enlargement cycles. Controlled chip formation reduces flute clogging and minimises the need for interrupted cutting or manual chip clearing, which supports higher feed rates and stable cutting forces. Improved chip control also contributes to a better surface finish inside the bore and reduces the risk of built‑up edge, especially when machining charted grades of steel and cast iron. For operations where cycle time and process reliability matter, optimised chip flow directly impacts throughput.

Tailored for P and K materials — explained

The insert is specified for material groups P and K according to ISO conventions: P = steel (including unalloyed and alloyed steels) and K = cast iron. This means the substrate and coating pairing are tuned to cope with the heat and continuous chips typical for steel, while also resisting the abrasive tendencies of cast iron. For production planners, that dual‑capability eliminates the need for multiple insert types for mixed batches, simplifying inventory and enabling flexible scheduling across diverse workpieces.

Practical production benefits and toolholder compatibility

As an indexable insert intended for drilling and hole enlargement, the geometry supports rapid seating and repeatable orientation in compatible toolholders, reducing setup time and enabling consistent cutting conditions. The robust edge toughness of the WKP35S grade helps to withstand transient loads and intermittent contact at bore entry. In practice, this yields fewer rejects and steadier dimensional results over long runs. The overall effect is a favourable balance of productivity and predictable maintenance intervals, making this insert a practical choice for job shops and production lines alike.

FAQ

What materials is the insert suitable for?
The P2840S-4N-F57 WKP35S insert from Walter Tools is specified for ISO material groups P and K, meaning it is suitable for steel and cast iron machining applications.

What benefit does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating improves thermal stability and wear resistance, which extends tool life and supports higher productive cutting conditions in continuous holemaking.

How does the 4N‑F57 chipbreaker improve drilling?
The chipbreaker 4N‑F57 produces short, controllable chips that evacuate reliably from the bore, reducing flute clogging and improving surface finish during drilling and enlargement operations.

Is this insert suitable for mixed‑material production batches?
Yes. The WKP35S grade is engineered to handle the heat and chip forms typical of steel while offering abrasion resistance needed for cast iron, making it a practical choice for mixed batches.

Which benefits affect total production cost?
Reduced downtime, fewer tool replacements and improved hole quality from the coating and chip control all contribute to a lower cost per finished part when using this Walter Tools indexable insert.
