Transferring impact and rotation by connecting DTH hammers through splines, DTH bits are put into blast holes together with DTH hammers for breaking stones. The DTH bits are divided into high air pressure DTH bits and middle-low air pressure DTH bits, which are mainly used in open-pit mining, underground mining, anchoring, quarrying, construction, etc.
