An auto body buffing and grinding machine has a fixed handle with a trigger mechanism, a surface with threaded opening for attachment of an adjustable handle, and an adjustable handle that is quickly and easily attached, adjusted, or detached. The adjustable handle has two angularly adjustable mechanisms working in mutually perpendicular planes, each being secured by a hand operable nut. One attachment mechanism works by insertion from the outside of the threaded opening and then the tightening of its associated nut against the surface surrounding the opening. The other attachment mechanism works by securing parallel plates with roughened surfaces together, and includes a spring normally urging the roughened surfaces of the plates apart. The plates are rotatable by more than ninety degrees.
