Down The Hole Drilling Tools

 DTH Drill Pipes

Length: 1000mm - 6000mm



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.DTH drilling enables drillers to reach hole depths that are double of what top hammer drilling can do. This is possible with the use of DTH Pipes and DTH Subs.


Drill pipe is a major drill component which connects rotary system,hoisting system,circulation system with drill collar and bit.Through it the rotary table drives the bit rotation,hook drives bit up and down and drill fluid flows to the bottom forming circle to make the bit breaks rock and reaches continuous drilling.


Down th hole drill pipes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability. KSQ DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe.The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.
