>> Application

DTH drilling is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.

Type:With or without foot valve

>> Application

DTH (Down The Hole) drill bit, also called spline connected drill bit, is mainly used in large scale mine (open and underground), open quarry and construction. The hammer is situated down the hole in direct connected with the drill bit with splines in the bit. The hammer piston strikes the drill bit resulting in an efficient transmission of the impact energy and insignificant power losses with the hole depth.

>> Application

The eccentric reamer drill is an overburden drilling system designed for conditions where a cased hole is required. Collapsing holes tend to make overburden drilling expensive, with lost drilling equipment and down time.

>> Application

The tricone drill bit is the most popular drill bit in the world, it can be widely used for oil&gas drilling, mining, water well, geological exploration areas.Our tricone drill bit is divided into metal sealed drill bit and rubber sealed drill bit.

IADC CODE:117 127 217

>> Application

Tricone bits, which some may also call roller cone bits or tri-cone bits, have three cones. Each cone can be rotated individually when the drill string rotates the body of the bit. The cones have roller bearings fitted at the time of assembly. The rolling cutting bits can be used to drill any formations if the proper cutter, bearing, and nozzle are selected.
