Rockmore International introduced its retrac reaming bit for tunneling, mining and underground construction drilling operations.

The bit is designed with unique retrac-style cutting fins in the rear section to promote better retraction out of the hole, according to the company. The fins effectively force out any rock chips from behind the bit when the drill string is pulled from the blasthole, resulting in more efficient reaming operations, Rockmore says.

“Our field support engineers recognized the need for better bit retrieval in face drilling operations,” says Pejman Eghdami, executive vice president at Rockmore. “After close collaboration with various drilling teams, our designers introduced the innovative retract features in this new reaming bit.”

Founded in 1948, Rockmore is a manufacturer of rock drilling tools for a range of industries.
