The Mincon MP60-QL is a 6 in. class down-the-hole hammer for rig-mounted drilling of 6 to 8 in. holes in quarry blast-hole, water-well, construction and mining work. The QL60 shank version carries a 5.6 in. outside diameter, 185 lb tool weight and 48 lb piston behind an API backhead thread, with a foot valve fitted as standard and Mincon’s proprietary heat treatment on every component.
Shank options QL60, MQ60 for footvalve-free tubeless bits, and Mincon’s own MC61 plus standard, button and backreamer backheads let the hammer match the DTH drill bits and casing system on your rig. For opening a cased hole past bit gauge, Crowder Supply also stocks a QL60 underreaming bit, and the DTH hammer buyer’s guide covers pairing hammer size to compressor output.
