Single shift record by wholly owned Kettle Drilling

"Kettle Drilling Inc. of Idaho, USA celebrated 10 years in business by setting a new drilling record – 609 feet (185.6 m) in a single, 10-hour shift. The company used Atlas Copco’s underground core drilling rig, the Diamec U8 APC for the job and surpassed their previous record by one foot (30.5 cm). The computerized Diamec U8 allows operators to download data from each hole, indicating, for example, penetration pressure, water pressure, rotation speed and weight on the bit. This allows drillers to select the correct parameters to optimize bit life and penetration rate."
