JCDRILL is one the professional manufacturer and supplier of high performance rock drilling tools like DTH Hammers and Bits. High middle low DTH hammer and Bit, DTH drilling pipes and Top Hammer Drilling Tools.Our tools are widely used in different drilling applications including mining, quarrying, water well drilling, geotechnical industries and etc.In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
