    • A tool support for mounting a working tool on a pipe comprises a base having inverted V-shaped saddle portions engaging the pipe and a clamping chain extending between opposite sides of the base for clamping the base on a pipe. A first end of the chain is mounted on one side of the base by a biasing spring arrangement which provides for limited displacement of the end in the direction of tensioning of the chain, and the free end of the chain is adapted to be releasably interengaged with an adjusting mechanism on the opposite side of the base and by which the chain is tensioned to clamp the base against a pipe. A pipe drilling tool is removably mounted on the base and includes a handle by which the tool can be carried and supported during mounting on and dismounting from the base and by which the base and tool can be carried as a unit.
