P4130-4R12-E47 WKK20S drill/boring indexable insert — coated carbide for cast iron | Walter Tools

A P4130-4R12-E47 WKK20S drill/boring indexable insert engineered to provide robust performance and controlled chip formation when machining cast iron materials.

• Tiger·tec Silver coating for long tool life
• Optimised chipbreaker 4R12-E47 for cast iron
• Coated carbide grade WKK20S for abrasive wear

Steady production through advanced coating and grade selection

The insert combines Tiger·tec Silver coating with the WKK20S grade, a coated carbide formulation tuned for abrasive cast iron applications. This combination increases tool life and reduces the frequency of index changes, which translates directly into lower process interruptions and more predictable production cycles. The substrate and coating technology are focused on withstanding the high abrasive wear typical of grey and ductile cast iron, so the cutting edge remains sharp for longer and delivers a consistent surface finish throughout batch runs.

Reliable chip control for secure machining processes

Equipped with the chipbreaker 4R12-E47, the insert promotes stable chip formation and effective evacuation during drilling and boring tasks. Short, controllable chips minimise the risk of snaring and reduce the need for manual chip handling, improving operator safety and machine uptime. In practical terms, the optimised chip geometry contributes to process security by lowering the incidence of unexpected tool stops and enhancing repeatability across successive holes and bores.

Practical integration and measurable productivity benefits

Designed as an indexable insert for drilling and boring operations, the designation supports straightforward replacement in standard toolholders and modular tool systems. The combination of high wear resistance and predictable edge behaviour reduces tool management overheads and helps maintain throughput in series production. The result is improved productivity and a more economic machining routine when working with cast iron components in workshop or production environments.

FAQ

What materials is this insert intended for?
The P4130-4R12-E47 WKK20S insert is specified for cast iron applications, reflecting the material group K and the WKK20S grade’s adaptation to abrasive, short-chip conditions.

How does the Tiger·tec Silver coating benefit tool life?
The Tiger·tec Silver coating on the WKK20S grade reduces abrasive wear and helps maintain edge integrity, which extends the service life of the Walter Tools drill/boring insert in repetitive cast iron operations.

What role does the 4R12-E47 chipbreaker play?
The chipbreaker 4R12-E47 shapes chips into shorter, more manageable forms, improving evacuation during drilling and boring and supporting consistent cycle times with fewer interruptions.

Is the insert compatible with standard toolholders?
The P4130-4R12-E47 is an indexable insert for drilling/boring tool systems; compatibility depends on the tool holder design, and Metav Werkzeuge can advise on specific holder models and mounting requirements.

How does this insert affect production reliability?
By combining a wear-resistant grade with controlled chip formation, the insert contributes to process security and repeatable results, reducing unplanned downtimes in serial machining of cast iron parts.
