Abstract
A hand-held knockout punch driver includes a housing, a motor, a drive assembly with an output member movable relative to the housing, and a head unit removably coupled to the housing. The head unit includes a body, an input member movable relative to the body, and a draw rod to which 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. The knockout punch driver also includes a quick-release mechanism to removably couple the body to the housing. The output member is configured to engage the input member such that the input member moves relative to the body in response to movement of the output member relative to the housing, and the body engages the quick release mechanism separately from engagement between the output member and the input member.
