• Tiger‑tec Silver coating for extended life
• Optimised for steel (P) and cast iron (K)
• Chipbreaker geometry 8R‑E67 for stable chips

Consistent process reliability for continuous production

The combination of the WKP35S grade and the Tiger‑tec Silver coating provides a balance of wear resistance and edge stability that translates into reliable cycle times. Designed as a coated carbide solution, the insert resists abrasive wear typical of cast components while managing the thermal loads encountered when machining steels. This reliability reduces unplanned tool changes and contributes to a steady production flow, which is especially relevant in high-volume or unattended machining environments.

Improved productivity through controlled chip formation

The designated chipbreaker 8R‑E67 supports controlled chip morphology, minimising the risk of chip-related interruptions and facilitating swarf evacuation in deep-hole or interrupted cuts. Stable chip formation reduces secondary operations and cleaning time at the machine, helping to increase effective spindle utilisation. Engineers will appreciate the measurable gain in throughput when replacing conventional grades with this optimised geometry.

Cost efficiency by extending tool life and repeatability

The coated carbide technology of this insert offers a longer effective life compared with uncoated grades, allowing for fewer indexings and replacements. Longer edge life directly reduces tooling consumption and handling costs. In addition, the repeatable performance of the grade ensures consistent dimensional results across batches, supporting quality control and reducing scrap rates in series production.

Clear application guidance and mounting considerations

Suitable for the ISO material groups P (steel) and K (cast iron), the insert performs well across a broad range of unalloyed and alloyed steels as well as grey and nodular cast irons. The designation indicates its intended use rather than the insert material itself. For best results, match the insert geometry to the holder and adjust feeds and speeds according to workpiece grade and rigidity; stable clamping and correct coolant strategies help to exploit the full potential of the WKP35S grade.

FAQ

What materials is this insert suitable for?
The P4840P-8R-E67 WKP35S is designed for machining ISO groups P (steel) and K (cast iron), with the Tiger‑tec Silver coating tailored to typical heat and wear conditions of these materials.

How does the WKP35S grade improve tool life?
WKP35S uses a coated carbide formulation that enhances wear resistance and edge stability; in combination with the Tiger‑tec Silver surface it provides longer cutting life and consistent performance.

What advantage does the 8R‑E67 chipbreaker offer?
The 8R‑E67 chipbreaker promotes controlled chip breakage and evacuation, reducing the likelihood of chip jams and improving process reliability during drilling and bore enlargement.

Is this insert compatible with standard drilling holders?
The insert designation P4840P-8R-E67 refers to the insert geometry; compatibility depends on the chosen holder type. Match the insert seat and clamping style with the holder specified by the tooling system.
