ABSTRACT:
A drill bit adapter tool is provided having a lock member, sliding member, and spring that are slidably positioned on the tool body. The lock member engages the driver of a drill and thereby holds the adapter tool to the drill. The lock member is disengaged to permit removal of the adapter tool from the driver by moving the sliding member, lock member, and spring relative to the tool body. The adapter tool facilitates convenient and rapid replacement of drill bits or other working pieces.
