  • DTH Hammer - HPE

    2009-11-1 · DTH is unique in that the more air pressure the hammer can hold, the faster the penetration rate. Most DTH hammers on the market today will hit anywhere from 1,600 to 2,300 beats per minute (bpm) at 350 psi 900 CFM, and most can steer in rock or dirt. They do not require much thrust or rotational torque for the hammer to work, and you do not have to anchor the drill.
