ABSTRACT:
A chuck for a rotary tool includes a body having a cylindrical bore for receiving the shank of a work performing member. A sleeve surrounds the body and forms an annular space in which is disposed a pair of opposed jaws which extend through opposed slots in the body for forcibly engaging the shank. The jaws each include an integral lever and an outer edge forming a fulcrum about which the levers are pivoted to force the jaws into engagement with the shank. A nut with a conical cam surface is threadedly disposed on the body and engages the levers in response to manual turning of the nut to clamp or release the shank.
