Hole Openers can be quoted with new/unused surplus or used Steel Tooth or TCI Cutters Hole Openers. At some point it may be necessary to increase the size of a pre-drilled hole to a larger diameter or to drill large diameter holes. Hole opener bits are designed specifically for this purpose. Bits are custom manufactured in a wide range of styles to meet field requirements. A custom hole opener is an effective way of enlarging holes, hence the name "Hole Opener". The Hole Opener Advantage Straighter Holes - By drilling a smaller hole with a "pilot" bit, then attaching that said bit onto the bottom of the the hole opener. The hole opener will follow the path of the hole drilled by the smaller bit. Larger Holes with Smaller Rigs - By drilling a hole in stages, larger holes can be drilled with smaller rigs. A smaller hole requires less power. Replacing Cutters and Cutting Cost - On most Hole Opener designs, the cutters can be easily replaced. The cost to replace a cutter is a fraction of the cost to replace a large tricone rock bit. Cost of Large Rock Bits - Larger diameter rock bits not only cost a lot, they can be difficult to find. A more economic solution is to use a hole opener that uses smaller tricone rock bit segments.. Flexability - Hole Openers can be fabricated in just about any size, and can be configured to drill through any formation. Operational Considerations Drilling Weight - The choice of drilling weight is determined based on the recommendations of the bit manufacturer and the number of cutters on the hole opener. Number of Cutters - The number of cutters placed on a hole opener is governed by the following facts: 1.Maximum number which will fit around the perimeter. 2.The greater the number of cutters, the less the weight, which therefore reduces the penetration rate. 3.In softer formations, less weight is needed to penetrate. 4.The greater the number of cutters, the smoother the tool will run. 5.The greater the number of cutters, the greater the cost. 6.The greater the number of cutters, the longer the cutters will last Rotary Speed - Maximum speed is determined by the manufacturer's recommendation and the calculation to account for the linear distance the cutter is moving per revolution. Hole Cleaning - A frequently over looked point of hole opener operation is hole cleaning. The volume of cuttings to remove from a hole increase by a squared factor with an increase in hole diameter.

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.
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.
