P4840P-1R-E67 WKP35S – Drill/boring indexable insert with Tiger·tec Silver coating, for Stahl and Gusseisen | Walter Tools

The P4840P-1R-E67 WKP35S is a coated indexable insert engineered for drilling and boring operations, offering enhanced wear resistance and controlled chip formation in machining applications involving Stahl and Gusseisen.

• Tiger·tec Silver coating for extended wear life
• WKP35S grade for coated carbide performance
• 1R-E67 chipbreaker for consistent chip control
• Optimised for drilling and boring in Stahl and Gusseisen

Predictable chip behaviour reduces downtime and improves cycle stability

The dedicated 1R-E67 chipbreaker provides predictable chip segmentation and evacuation, which lowers the risk of tool jamming and reduces cycle interruptions. In practice, controlled chip formation supports uninterrupted machining sequences and simplifies chip management in multi-shift production. For operations that must balance throughput and safety, consistent chip control is a concrete contributor to improved overall efficiency. The geometry of the insert promotes reliable chip flow in both interrupted and continuous cuts, helping to maintain machine uptime.

Coating and grade extend tool life while maintaining edge stability

The combination of Tiger·tec Silver surface technology and the WKP35S coated carbide composition increases resistance to abrasive and adhesive wear under typical cutting conditions for Stahl and Gusseisen. This results in a stable cutting edge and a longer effective tool life compared with uncoated grades, which directly reduces tooling costs per component. The coating also supports improved thermal resistance, meaning machining parameters can be maintained for stable productivity without premature degradation of the cutting geometry.

Integration into indexable drilling systems for cost-efficient production

As an indexable insert designed for drilling and boring, the P4840P-1R-E67 geometry allows multiple edge usage and quick index changes, cutting non-productive time during fixture changes. The insert’s design is optimised for common drilling cycles and CNC boring applications, providing a practical route to lower per-part tooling expense while maintaining consistent hole quality. Where exacting tolerances are required, the repeatable edge performance helps keep batch variation to a minimum and supports predictable process results.

Application guidance and material suitability

The WKP35S grade is targeted at the ISO groups P and K, meaning the insert is suited for machining Stahl (unalloyed and alloyed steels) and Gusseisen, with a balance between wear resistance and toughness appropriate to these materials. Selection of cutting speeds, feeds and toolholder rigidity should follow machine and workpiece constraints; the insert’s properties favour stable cutting parameters that promote surface finish and dimensional consistency in serial production.

FAQ

Which materials are recommended for this insert?
The P4840P-1R-E67 WKP35S insert from Walter Tools is recommended for machining Stahl and Gusseisen, reflecting the ISO P and K material group suitability.

What benefit does the Tiger·tec Silver series provide?
The Tiger·tec Silver technology enhances wear resistance and thermal stability of the WKP35S grade, delivering longer tool life and more consistent edge performance under typical drilling and boring conditions.

How does the 1R‑E67 chipbreaker influence machining?
The 1R‑E67 chipbreaker shapes chip formation for controlled segmentation and reliable evacuation, reducing the likelihood of chip-related interruptions and supporting steady production cycles.

Can the insert be used in standard indexable drill holders?
The insert is designed for indexable drilling and boring systems; compatibility depends on the holder geometry and clamping system—confirm holder support for the P4840P-1R-E67 geometry before fitting.

How often should the insert be indexed or replaced?
Indexing frequency depends on process parameters and wear rates; the WKP35S grade and Tiger·tec Silver coating typically extend edge life, but inspection intervals should follow in-house quality criteria and component tolerances.
