Sandvik has released its new longer life +Range of surface mining drill rods and tubes.
The manufacturer said this new +Range is designed with premium grade steel alloy, developed by Sandvik Material Technology, which can increase service life by more than 30%, and in turn reduce rod changes, cut operating costs, and slash handling.
They have been designed for surface mining bench drilling application, such as production blasthole drilling and pre-split drilling.
Sizes available include T38+, T45+, T51+ and GT60+, and includes top-hammer MF (male/female) rods and drill tubes, Sandvik says.
The rods have been tested to Australian conditions, and have proven a longer life on the job, Craig Johnston, Sandvik's Business Line Manager – Rock Tools, said.
“This increased service life results from Sandvik’s new steel alloy, which is far more resistant to heat and thread wear,” Johnston said
“With drill rods and tubes representing a significant part of tool cost in bench drilling, a 30% plus increase in tool life allows customers to drill more metres every shift, and reduce drill costs per metre.”
He explained that as the industry is digger deeper for longer the consumption of drill rods and tubes is only likely to rise.
“Keeping rod and tube expenses under control will be more important than ever – and our premium +Range will offer one of the longest service lives in rock tools.”
He went on to say that as there are few rod changes safety and costs are increased.
“Fewer rod changes are required with our new rock tools, resulting in less transporting and handling of equipment. This minimises exposure to risks such as strain and back, arm and hand injuries.
“And because of the extended service life, our new +Range products require fewer shipments and less transporting once on site, and fewer rods to recycle. “In addition, the manufacturing process for our +Range tools uses less energy and fewer raw materials, further reducing their impact on the environment,” said Johnston.
