World-record Drilling

July 16, 2007
Two-cone rock bit drills almost 5 miles and sets three individual records.

Timken Co. reports that an end user, Houston-based Smith Technologies, has been recognized for setting three world records with a two-cone rock bit made from Timken steel. In February, Smith Technologies’ two-cone bit was used in Qatar to drill the longest single distance by a roller-cone bit – 24,591 feet.

Made of two specialized grades of alloy steel forging bar, the rock bit used for a gas well in Qatar set three individual records: longest distance drilled with a roller-cone bit, longest distance drilled with a milled-tooth bit and longest distance drilled by a two-cone bit.
