In down-the-hole drilling a drill rod is fitted with a hammer at its lower end. The hammer, which is mounted on the drill bit, is activated through the addition of compressed air and driven into the ground – simultaneously rotating and impacting. A flushing current collects the loosened drill cuttings and conveys them Geosystems LP[PDF]AN INTRODUCTION TO WATER-POWERED DOWN-THE Rotary percussive (down-the-hole hammer) drilling is typically preferred in medium-hard materials for holes over 4-inch (101 mm) diameter and over 40 feet ( m) deep. High pressure, high volume flushing media are required, whereas feed and torque requirements are low. DTH drilling has many advantages over top Drilling Supply StoreDTH Hammers - Drilling Supply StoreDown-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. 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.Sandvik Mining and Rock TechnologyDown-the-hole drilling tools - Sandvik Mining and Rock Down-the-hole hammers DTH hammers combine intensive impact power with low energy loss and reduced fuel consumption.
