DTH (Down-The-Hole)Drilling Tools

DTH Bits

Transferring impact and rotation by connecting DTH hammers with splines, DTH bits dive into blast holes together with DTH hammers for breaking rocks. The DTH bits are divided into high air pressure and middle-low air pressure DTH bits, which are mainly used in surface mining, underground mining, bolting, quarrying, construction, etc.
