The tool may have a straight shank, tapered shank, bit stock shank or special shank requiring a special holder, for holding in a power- or hand-operated machine. It may be designed to be driven or turned by means of a wrench or carpenter's brace. For items requiring a holder but the holder is not included, use CUTTER, COUNTERSINK. View more Countersink
