Abstract
A hand tool for performing an axially reciprocating operation on a workpiece includes a rigid drive member having a longitudinal axis and a coupling formation for releasably securing one of a plurality of task-specific attachments, the coupling formation configured for engaging the attachments along the axis, and a handle portion operatively connected to said the member for grasping by a user to apply force to a workpiece through the drive member to perform an operation thereon. The drive member may be reciprocated manually or by a motorized mechanism. The coupling portion of the drive member secures the attachment against unwanted axial movement. The attachment exerts a clamping force on the drive member.
