P2840S-3N-E67 WKP35S – indexable insert for drilling and reaming, Tiger·tec Silver (Walter Tools)

The P2840S-3N-E67 WKP35S is an indexable insert developed for productive drilling and reaming in steel and cast iron, combining a modern coating system with a geometry optimised for controlled chip formation.

• Tiger·tec Silver coating technology
• WKP35S grade for high wear resistance
• 3N‑E67 chipbreaker for reliable chip control
• Optimised for steel and cast iron machining

Maximised machining performance through advanced coating and grade

The Tiger·tec Silver coating, paired with the WKP35S coated carbide grade, reduces flank and crater wear under the thermal and mechanical loads typical of steel and cast iron cutting. This combination improves tool life and stabilises the cutting edge, which in turn lowers the frequency of index changes and supports predictable production planning. The coated substrate is engineered to resist abrasive wear while maintaining edge integrity at elevated cutting temperatures, offering a measurable advantage in cycle‑time‑sensitive operations.

Reliable chip control for consistent hole quality

The 3N‑E67 chipbreaker geometry is designed to produce short, controllable chips in both P (steel) and K (cast iron) materials, minimising re‑cutting and the risk of surface damage. Stable chipflow reduces interruptions and helps maintain hole diameter and surface finish within tight tolerances. For drilling and reaming applications where repetitive quality is required, the insert’s geometry contributes directly to lower scrap rates and fewer tool interventions, translating into more consistent batch outputs.

Practical benefits and application guidance for process engineers

Specified for machining tasks in the P and K material groups, this indexable insert supports a broad range of drilling and reaming conditions found in general engineering and heavy‑duty production. The WKP35S grade is aimed at balancing wear resistance and toughness, making it suitable where both abrasive cast iron and tougher steels are processed. Process windows can be tightened thanks to the coating and chipbreaker, enabling higher cutting parameters without sacrificing component integrity.

FAQ

What materials is the insert suitable for?
The P2840S-3N-E67 WKP35S insert is suitable for the ISO P and K groups, i.e. steels and cast iron, benefitting from the Tiger·tec Silver coating and tailored chipbreaker.

Which chip behaviour can be expected with the 3N‑E67 geometry?
The 3N‑E67 chipbreaker promotes short, controllable chips in both steel and cast iron, improving chip evacuation and reducing recutting during drilling and reaming operations.

How does the Tiger·tec Silver coating influence tool life?
Tiger·tec Silver enhances thermal stability and wear resistance of the WKP35S grade, leading to longer edge life and fewer index changes in demanding machining cycles.

Is this insert intended for reaming as well as drilling?
Yes, the indexable design and geometry are engineered for both drilling and reaming tasks where consistent hole quality and controlled chip formation are required.

Can the insert be used in automated production cells?
The stability of the WKP35S grade and the chip control of the 3N‑E67 geometry make the insert suitable for automated environments that require repeatable performance.
