Abstract
A hand-held knockout punch driver includes a housing, a motor positioned within the housing, a head unit removably coupled to the housing, the head unit including a body, an input member movable relative to the body, and a draw rod to which at least one of a punch or a die is attachable. The draw rod is configured to move axially relative to the body in response to movement of the input member relative to the body. A quick-release mechanism removably couples the body to the housing and includes radially inward-extending locking members on one of the housing or the head unit and a plurality of radially outward-extending locking members on the other of the housing or the head unit engageable with the radially inward-extending locking members to lock the head unit to the housing.
