Abstract:
A quick-release multi-drive drill motor chuck for receiving a rotary tool is provided. The chuck body has a first end, a second end, and an axis and a defined cylindrical bore from the first end toward the second end. The chuck body defines a plurality of orifices extending from the bore at a finite distance from the first end, the chuck body defining a keyway or relief embodiment in the first end. A plurality of detent balls are disposed in the plurality of orifices such that one ball is placed inside of each orifice. A collar having an axis is disposed concentrically around the chuck body in axial slip fit relationship, such that slipping the collar axially along the chuck body will alternately expose the orifices to either the inner wall or a recess, thereby positioning said recess for receiving the detent balls.
