DTH BIT

DTH drill bit (also called DTH drill bit) is a kind of rock drilling tool used in supporting DTH drilling rig. The down-the-hole drill bit, the down-the-hole impactor and the down-the-hole drill pipe together form the down-the-hole drill tool. The working principle of the down-the-hole drill tool is to use compressed air as the power to submerse the rock drilling impact power part into the rock drilling hole, and the air distribution device in the impactor controls the piston to make a reciprocating motion to impact the down-hole drill bit and the drill bit breaks the rock. DTH drilling tools are mainly used in open-pit mining, geothermal drilling of water wells, quarries, excavation of building foundations, anchoring operations of water conservancy and hydropower projects, etc. Compared with other rock drilling machinery and equipment, the DTH drilling tool has a deep drilling depth, a large drilling hole size, a high drilling straightness, a low investment in the DTH drilling machine, and a wide range of applications.

Production process of down-the-hole drill bit: steel incoming inspection-brazing body processing-trouser body heat treatment-drilling tooth hole-inlaid alloy tooth-anti-corrosion treatment-product inspection-packaging and warehousing
