Challenger - Model RC100 -Down Hole Hammer

Valveless down hole hammer design. Ability to drill efficiently against high heads of water. Designed to operate at pressures up to 250 PSI (17.0 BAR). Reversible non-ported piston case for extended life.  Superior directional stability in horizontal applications. Ejecting cuttings through the collection tube eliminates traditional hole cleaning problems. Environmentally sensitive- no foam required for hole cleaning and lubricants are not free to contaminate the formation. Typical vertical and horizontal applications include: caissons, piles/rock sockets, tunneling underloads, foundation drilling and other jobs where large volume rock excavation is required.
