The Mincon MP120 is a large-diameter down-the-hole hammer for 12 to 15 in. bits the class of tool foundation-piling, deep water-well and production drilling rigs turn to when hole size outgrows mid-range hammers. Choose QL120, N125 or SD12 shank support to match your bit inventory; every variant carries a 10.8 in. outside diameter, an API backhead thread and a factory-fitted foot valve, machined and heat treated in Mincon’s Ireland and Finland plants.

Tool weight runs 998 to 1,014 lb by shank variant with pistons of 288 to 305 lb, so plan rig handling and compressor capacity accordingly. It anchors the big end of the DTH hammer lineup at Crowder Supply; the step down is the MP100-SD hammer for 10 to 12 in. bits. Face it with matched DTH drill bits and lean on the DTH hammer buyer’s guide when sizing the air package.
