The coupling sleeve is an indispensable part of rock drilling tools for rock drilling. During the drilling process, the coupling sleeve is at the joint part of the matching drill, which bears the corrosion effect of stress such as axial tension and compression, bending and torsion, contact, and friction. The coupling sleeve used for threaded connection rock drill tools is to use its thread to connect two or more drill rods or shank rods on the same axis, transfer the impact function of the rock drill, and achieve the purpose of drilling rock holes, which is the same as the drill rod. It acts as a stress wave propagation carrier. Coupling sleeve classification 1. Classification by the geometric structure There are straight-through coupling sleeves, reducing coupling sleeves, and middle-stop-type coupling sleeves. 2. Classification by thread structure There are coupling sleeves such as wave thread, compound thread, trapezoidal thread, etc. Product Parameters Coupling sleeve type: full bridge coupling sleeve and reducing coupling sleeve Thread size: R32, R38, T38, T45, T51.

Drag bit is a drill bit usually designed for use in soft formations such as sand, clay, or some soft rock. However, they will not work well in coarse gravel or hard rock formations. Uses include drilling water wells, mining, geothermal, environmental and exploration drilling. Whenever possible, they should be used to drill pilot holesbecause they produce cuttings that are easiest to log.
Eccentric casing Systems Drilling through formations with loose, unconsolidated material always comes with problems such as the bore hole cave-in collapse. How to avoid these problems? With years of field practice and research, Team whole had developed its eccentric casing system application for strata with silt, sand or small size pebbles. With its simple structure,easy operation and reliable performance, this system can advance the casing easily for depth within 30 meters. And it's retrievable with long service life. Concentric Casing Systems Usually the land surface of the earth is covered with loose, unconsolidated material such as soil, clay, silt, sand, gravel and boulders, which varies in depth from a few centimeters to hundreds of meters. Use concentric system can drill this complex formation very well. The systems are available through the whole product range the smallest being for 114 mm (4 1/2") casing and largest size available at the moment is for 1220 mm (48") casing.
TOP HAMMER drilling tools include: bit, rod, shank and sleeve. The piston of drill rig directly impacts the shank, makes impact power reach the bit through rod by the form of stress wave, so as to work on the breakage of rock. The primary breaking way is impacting while the secondary is cutting; both are with high drilling efficiency.
