Sandvik has introduced its new Golden Shank, a corrosion protection coating for increased service life and lower drilling cost per metre.
Sandvik’s Golden Shank is equipped with a low-friction, nickel-plated coating with a polymer top sealant for improved corrosion resistance.
Applied throughout the entire shank and flushing slot, this coating minimises wear on flushing seals and rock drill parts while reducing breakages on other rig and tool machine parts.
“Prioritising operator safety and minimising environmental impact through reduced tool replacements are critical considerations in our product development process,” Sandvik Mining and Rock Solutions product manager top hammer Thomas Blomfeldt said.
The Golden Shank will enable some customers to potentially double efficiency.”
Sandvik’s field tests have confirmed a 30–100 per cent longer product life.
Even at mine sites where corrosion is not prevalent, Golden Shank field tests have consistently demonstrated two to three times longer performance life.
The extended service life of the shank adapter enhances safety and sustainability for customers by reducing operator handling and heavy lifting, inventory needs and emissions from transportation.
A coating with less environmental impact also improves the sustainability footprint in manufacturing.
