Hyper Deep Hole Hammers
Created on：2020-09-07 20:13
The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs. Roschen group limited offers a wide range of DTH hammers suitable for a variety of drilling operations.
