Sandvik Introduces Golden Shank

Sandvik’s new Golden Shank is equipped with a patented, low-friction, nickel-plated coating with a polymer top sealant for improved corrosion resistance. Applied throughout the entire shank and flushing slot, except for the striking area, this coating minimizes wear on flushing seals and rock drill parts and reduces breakages on other rig and tool machine parts, says the company.

“Prioritizing operator safety and minimizing environmental impact through reduced tool replacements are critical considerations in our product development process. The Golden Shank will enable some customers to potentially double efficiency.” said Thomas Blomfeldt, Product Manager Top Hammer at Sandvik Mining and Rock Solutions.

Sandvik say that field tests have confirmed 30-100 percent longer product life. Reaching further between service intervals enables customers to proactively schedule shank adapter replacements during intended service stops and mitigate time-consuming and costly occurrences of unexpected breakage during ongoing drilling operations.
