ABSTRACT:
A modular broach handle for use with a broach having a tapered configuration beginning at a wider upper end tapering to a smaller lower end. An elongated handle body portion has a longitudinal axis, with one end portion of the handle body defining a connection end portion for attaching a broach thereto at the wide upper end portion of the broach. A slot extends a distance along the handle terminating at one end thereof adjacent a connection end poriton of the handle body. A socket communicating with the slot is formed at the connection end portion of the handle body, the socket having an open end portion receptive of an attachment post on the wide end portion of the broach. A spring loaded slider bar is disposed within the slot for sliding movement therein and with respect to the handle between engaged and disengaged positions, and includes an end portion that extends into the socket when in the engaged position to form a connection with the post. The slider bar and handle socket form a releasable locking mechanism between the post of the broach and the handle that is perfected upon assembly by pushing the post into the socket, without manipulation of the slider bar.
