An impact tool driver is provided and configured for removable attachment to a drive spindle of a power tool, for example a conventional drill. A body member is removably attached to the drive spindle and includes a first impact member containing a number of radially spaced impact lugs defined thereon. Second impact member includes a number of radially spaced impact lugs in engaging and opposing contact with the impact lugs defined on the first impact member. A drive member is connected to the second impact member and is rotational mounted on the body member. The drive member includes a device for connecting a tool or working device thereto. Rotational drive of the body member and the first impact member is imparted to the second impact member and drive member through rotational impacting engagement of the impact lugs.
