P4840C-8R-E67 WKP35S — drill/boring indexable insert, Tiger‑tec Silver (Walter Tools)

A robust P4840C-8R-E67 WKP35S indexable insert engineered for high‑productivity drilling and boring operations in steel and cast iron, combining a Tiger‑tec Silver surface treatment with a dedicated chipbreaker geometry.

• Tiger‑tec Silver coated carbide grade WKP35S
• Optimised for steel and cast iron machining
• Stable chip control for consistent productivity
• Reliable edge life for repetitive operations

Achieve consistent cutting performance with optimised coating and grade

The combination of the Tiger‑tec Silver technology and the WKP35S grade delivers a dependable balance between wear resistance and toughness. Designed as a coated carbide solution, this insert copes with the typical heat and abrasive conditions encountered when machining steel and cast iron, which reduces flank wear and extends useful tool life. The result is a measurable increase in process stability and fewer indexings per component batch, supporting higher overall throughput in series production.

Secure process reliability through controlled chip formation

The 8R‑E67 chipbreaker geometry provides predictable chip control under the cutting conditions typical for P and K materials. Stable chip formation reduces the risk of interruptions and toolholder damage, enabling smoother coolant flow and easier chip evacuation. In practical terms, this means reduced cycle‑time variability and more consistent surface finishes, which benefits both component quality and downstream assembly processes. The insert’s reliable edge retention supports repetitive performance across production runs.

Easy integration into existing tool systems and predictable handling

As an indexable insert for drilling and boring applications, the design is compatible with standard toolholders that accept the P4840C‑style designation. The clear material classification (P / K) makes process planning straightforward: select the WKP35S grade where steel and cast iron predominate. Documentation and handling procedures remain simple thanks to the standardised designation and visible chipbreaker marking, allowing quick identification and replacement during shift changes. This pragmatic approach aids maintenance planning and reduces machine downtime.

FAQ

What materials can this insert machine effectively?
The insert is designed for steel (P) and cast iron (K), with the WKP35S grade optimised for the thermal and abrasive conditions typical of these material groups.

How does the Tiger‑tec Silver coating improve performance?
Tiger‑tec Silver increases wear resistance and reduces built‑up edge on the cutting lip, so the P4840C‑8R‑E67 WKP35S maintains cutting geometry longer and supports more consistent component quality.

Is the chipbreaker suitable for interrupted cuts?
Yes, the 8R‑E67 chipbreaker is engineered to provide controlled chip formation, which is beneficial in interrupted and continuous cuts common in drilling and boring.

Can this insert be used in existing holders with P‑style designations?
The insert follows the P4840C designation and is compatible with holders engineered for that style, enabling straightforward replacement and integration into current tooling systems.

What production benefits can be expected from using this grade?
Expect improved process stability, fewer tool changes due to longer edge life, and more consistent surface finishes—advantages that translate into higher productivity and lower per‑part machining time.
