Sandvik launches hybrid tools for longwall applications

SANDVIK Mining’s new hybrid cutting tool provides smooth cutting efficiency and durability in conditions ranging from soft rock to the harshest of environments, the company says.

The new hybrid design offers a blend of the efficient cutting characteristics of its patented cap designs, combined with the durability and long life of an insert style tip. This can eliminate the need to stop and change tools when conditions change, saving time and money.

Sandvik hybrid tools are robust, but they feature an optimised profile for speed and productivity.

Their design offers a tool with an efficient “slim” profile but outlasts larger tools with wide, blunt designs, enabling higher production rates and increased revenue.

The tapered lower portion provides added strength and stability precisely where it’s needed, minimising the risk of breakage. This amounts to fewer interruptions for maintenance and, as a result, more time spent producing, according to product line support manager for Sandvik mineral ground tools Mark Salter.

“Our hybrid tips have also been designed with safety in mind, they contribute significantly to improving our customers’ working conditions,” he said.

“This is achieved via our low energy profile tip that penetrates better and generates less dust. Thanks to the robust design less time is spent changing tools and reducing human exposure to the working face.

“This coupled with increased up-time, higher productivity and the ability to work in a variety of conditions means lower cost per tonne at the end of the day.”

The new Sandvik hybrid tools come in a variety of sizes that range from 30mm shank to 43mm for longwall applications. Hybrid cemented carbide tips include widths from 18mm to 25mm.
