COPROD is the name of Atlas Copco’s patented system of rigs and drill tubing that offer the high penetration rate of tophammer drillstrings with the hole straightness and hole quality of DTH drillstrings. The ROC F9 CR is the smaller of the two COPROD drilling rigs and uses CR76 or CR89 tubes to drill holes 90–127 mm in diameter. ROC L740 CR, a second-generation COPROD drilling rig, can be equipped with CR89, CR102, CR127 or CR 140 drillstrings to produce holes 105–180 mm in diameter. The company has developed the third generation COPROD drillstrings for introduction to the market in 2010. The objectives of the new design, it explains, were to improve hole straightness and reduce noise; the solution was achieved by removing the welded center guides in the drill tubes and replacing them with a  patented plastic stabilizer with a unique geometrical design that acts as an inner lining, reducing vibrations in the tube while dramatically reducing noise levels. The COPROD 102- and 127-mm products were scheduled to reach the market in the first quarter of 2010, with the rest of the range to be launched during the second half of the year.
