ABSTRACT:
A hand tool having a motor rotating a drilling bit is made more useful by a power transmission collar. An auxiliary tool, such as a riveter, scheduled for use selectively during intervals between drilling operations, is powered by the electric drill. The auxiliary tool has a driven member with a well adapted to receive the bit. A power transmission collar is secured to the bit near the chuck of the drill. The collar has self-guiding spiral surfaces and pin-engageable surfaces. The driven member has a socket featuring a single pin toward which the spiral surfaces guide the collar to the pin-receptive surface for the power transmission connection.
