The optimum range of hole size for blast hole drilling with DTH is 76 mm to 254 mm (3”–10″). Smaller blast holes are generally drilled using tophammer hydraulic drifter, and larger holes generally use DTH rotary machines.
Our DTH hammers are widely used in rock drilling, mineral exploration, mining, quarrying, water well, construction, foundation, HDD, horizontal boring, oil & gas and geothermal of the drilling industries.
DTH drill pipe is made of high-quality alloy steel, and the seamless steel pipes at both ends are connected by friction welding, it’s mainly used for rock drilling and crushing, anchor drilling, geothermal air conditioning drilling holes, water well drilling etc.
DTH hammer spare parts include drive chuck driver sub, back adapter top sub, O-ring, check valve dart, spring, steel washer, disc spring, rigid valve air distributor, internal cylinder, piston, control tube piston case external cylinder, retainer sleeve, bit bearing, bit retainer ring stop ring, “O” ring of stop ring, guided sleeve, seal kit, consumable etc.
DTH Odex drilling system includes eccentric overburden and concentric drilling equipment, such as ring bit, central drill bit, guide device, casing shoe, casing tube, reamer, pilot bit etc., which will be matched with related DTH hammers.
