The Mincon MP100-SD is an 8.6 in. OD down-the-hole hammer that water-well drillers, blast-hole production crews and foundation-piling contractors run for 10 to 12 in. holes. It weighs 650 lb with a 172 lb piston, takes SD10 shank bits, and connects to the drill pipe through a 6-5/8 API backhead thread foot valve included, with impact delivered right at the bit no matter how deep the hole gets.

Because the hammer travels with the bit, penetration stays consistent on deep wells and anchor shafts where top-hammer energy would die in the string provided the rig’s compressor and booster are sized for high-pressure DTH service. Browse DTH drill bits for the business end, step up to the MP120 hammer when the plan calls for 12 to 15 in., and let the DTH hammer buyer’s guide and the complete down-the-hole hammer range frame the choice.
