SERIES AC-600

Blade Sizes 3⁷/₈" (98.4mm) through 6¾" (171.4mm) for air, water or mud

The Series AC-600 bit is desgned for heavy weight drilling, usually employing the use of 2³/₈" (60.3mm) or 2⁷/₈^" (73mm) tool joint or heavy-duty drill pipe to drill holes from 4¼" (108mm) through 5⁵/₈" (142.9mm). While drilling through shale and other formations of similar strength with 6" (152.4mm) or larger bits using 3½" (88.9mm) and 4½" (114.3mm) drill pipe, it is recommended that Series SH-800 bits be used.
