Down the Hole Hammers

Down-the-hole (DTH) hammers ride at the bottom of the drill string, right behind the bit, so impact energy stays strong at any depth — the reason DTH drilling stays fast and straight in hard rock where top-hammer drills fade. We stock the Mincon MP-Series DTH hammers and sell Rock Hog and Rockmore lines to order, covering every hole from 3 to 24 in. Bits are universal — chosen by shank designation (DHD, QL, SD) and head diameter, not by brand — so match the shank family to your hammer and the head to your hole. New to DTH? Our DTH hammer buyer’s guide walks hole size, air, pressure, foot valve, and shank in order. For shallower holes, see handheld rock drills.
