Hydraulic adapter / drill pipe / threaded

Threaded directly into the spindle of the rotary gearbox, the Foremost Cushion Connector helps protect the rotary drive and mast assembly against torsional and axial vibrations and shock loading in moderate and extreme drilling conditions. The result is reduced drill maintenance, increased uptime and lower drilling costs.

Disc springs are utilized which allow a range of axial movement between the drill stem and the rotary drive. The disc springs accommodate operating loads ranging from 8,000 to 120,000 lbs. (3,630 - 54,430 kg). In most cases, this is sufficient to help keep the tri-cone bit in continuous contact with the formation, thereby reducing the possibility of fracturing or breaking the carbides in the bit.
