Down the Hole Hammers

Drill deep, straight holes in hard rock with down-the-hole hammers that ride right behind the bit so impact stays strong at depth. Mincon and Rock Hog DTH hammers cover water-well, quarry, and foundation drilling, paired with matching DTH drill bits.

Deep, Large-Diameter Holes

DTH hammers keep penetration high where surface hammering fades, with hammer sizes matched to bit diameter and air pressure. Run them on an air compressor with the volume to drive the hammer, and see DTH bits for the cutting end. For handheld drilling, see rock drills, or our guide to choosing a rock drill.
