A well pipe spinner includes two body parts carrying rollers and mounted by two pivotal connections for swinging movement between a closed position in which the rollers grip and drive a well pipe and an open position releasing the pipe. A structure extends between and interconnects the two pivotal connections in a relation permitting relative adjustment of their pivotal axes toward and away from one another for gripping different sizes of pipe. The tool is supported by a structure which is adapted to be suspended from a line or other element and which suspends the two body parts and pivotal connections at essentially the locations of the two pivotal axes.
