P2840S-2N-F57 WKP35S Drilling/Boring indexable insert, Tiger-tec Silver, for Steel & Cast Iron — Walter Tools

The P2840S-2N-F57 WKP35S is an indexable insert engineered for high-productivity drilling and bore-enlargement in steel and cast iron applications, combining a wear-resistant coating with a geometry that stabilises chip formation.

• Tiger-tec Silver coating for extended tool life
• Optimised chipbreaker 2N-F57 for stable chip control
• Engineered for steel and cast iron machining

Boosted performance through advanced coating and grade

The combination of the Tiger-tec Silver coating and the WKP35S cutting grade provides a noticeable increase in tool life under demanding conditions. The coated carbide substrate resists abrasive wear and reduces the risk of built-up edge during continuous drilling cycles, which translates into higher productivity and less frequent index changes. For shops seeking predictable tool behaviour, the coating technology supports elevated cutting parameters without compromising edge integrity, so machining sequences remain stable over longer runs.

Consistent chips and fewer interruptions

The 2N-F57 chipbreaker is designed to produce short, controlled chips when machining typical P- and K-group materials. This stable chip control reduces the likelihood of chip entanglement and minimises secondary operations to clear swarf, improving process security and surface finish consistency. In practice, operators will notice fewer stoppages during bore-enlargement and better evacuation of chips from the cutting zone, which helps preserve tool edges and workpiece quality when working with steel and cast iron.

Clear application range and material guidance

This insert aligns with ISO material group standards and is optimised for the P (steel) and K (cast iron) families, offering a versatile solution for mixed-production environments. The P2840S-2N-F57 WKP35S grade is particularly suitable where a balance between wear resistance and toughness is required; it performs well in both roughing and semi-finishing cycles. For customers less familiar with ISO groupings, the classification indicates reliable behaviour for unalloyed, alloyed steels and abrasive cast materials, simplifying tool selection in multi-material batches.

Reduce downtime and increase process reliability

Investing in an insert with a robust grade and a tuned chipbreaker supports repeatable results and lowers total machining cost through reduced tool changes and consistent part quality. The design emphasises process reliability: fewer edge failures, predictable wear progression and improved surface integrity.

FAQ

What materials is this insert best suited for?
The insert is developed for machining steel and cast iron according to ISO groupings; the WKP35S grade balances wear resistance and toughness for these materials.

How does the Tiger-tec Silver coating help in production?
The Tiger-tec Silver coating reduces abrasive wear and improves performance at higher cutting speeds, helping to extend the service life of the insert and maintain stable cutting conditions.

What benefit does the 2N-F57 chipbreaker provide?
The 2N-F57 chipbreaker promotes short, controlled chips which improves chip evacuation during drilling and bore-enlargement operations, leading to fewer interruptions and a more consistent surface finish.

Is this insert suitable for roughing and finishing operations?
Yes, the combination of the WKP35S grade and the insert geometry supports both robust roughing cuts and semi-finishing passes in steel and cast iron.
