DTH Hammers

A down-the-hole hammer delivers percussive impact directly at the bit face, so almost all of the drill rig's air energy becomes rock-breaking energy. That makes DTH the tool of choice for drilling through competent rock where rotary bits would stall. The rig supplies rotation and down-pressure; the hammer supplies the impact.

Drillworx stocks DTH hammers across the full contractor size range: 3" and 4" for water-well piloting, 5" and 6" for bread-and-butter water and geothermal work, 8" and 10" for larger municipal and foundation bores. Shank options include IR 3 and 4, Mincon, Numa, and Epiroc-compatible — pick the shank that fits the bits your shop already stocks rather than starting a new bit inventory.

Hammer selection is not just about bore diameter. Air consumption, rig pressure capacity, and down-pressure rating all need to match. A hammer that is too big for the compressor drills slow; one that is too small for the rig under-utilizes the equipment. The salesperson for your region can help you pair hammer, bits, and compressor before you spec tooling for a new ground type.
