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.
Overburden systems

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.
Rock Drills Other stone breaking tools
DOWN THE HOLE drilling is a kind of big diameter borehole drilling by extending the impacting power to the bottom of the hole. With high straightness, clean hole wall, good rigidity of drill pipe and hammer, without high axial thrust, no restriction of drilling depth and low cost, DTH drilling tools are widely used in open-pit mining.
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.

The down-the-hole hammer is a new type valveless hammer driven by compress air.It is the ideal rock drillling tool with advages of large impact energy,high penetration rate,long service life,good efficiency of drilling cuttings removal,easy operation,reliable working performance and so on. TH----for wet drilling Wadely applied to all kinds of rock boring hole drilling and excellent in projects for casing system and water well drilling. Can be matched to various types of hammers popular in the world and drill the holes from 76mm to 1200mm in diameter. TS----for deep hole and super deep hole drilling Can be meet to the needs of drilling holes from 203mm to 660mm in diameters. TG----for drying drilling Have stable performance, fast speed, long service life in sleeves, and 10% less air consumption than other ordinary hammers, and can also work well without the foot valves. Drill holes from 90mm to 254mm. All our Hammers can be easily adapted to accept different types of bit shanks as COP, BR, DHD, SD, XL QL, MACH, Halco and Mission by simply changing a few basic components. Several models are available in Heavy-Duty format to suit particularly arduous and abrasive drilling conditions. In wooden case or in carton
