Abstract
A tool comprising a housing having a handle and a distal end wherein the distal end includes a spindle capable of receiving a bit and defining an axis of rotation. The tool further comprises a quick-release chuck assembly that includes a sleeve and a trigger. The sleeve is disposed about the spindle and spring biased in a locked position wherein the sleeve is capable of being moved axially to an unlocked position to permit insertion of such a bit. The trigger includes a finger receiving portion and an actuator portion where the finger receiving portion extends from the housing in a position that enables the user to actuate the trigger with a finger of the hand holding the handle. The actuator portion is in physical communication with an engagement portion of the sleeve wherein the activation of the trigger causes the sleeve to move axially to the unlocked position.
