ABSTRACT:
The present invention is a tool holder which permits lateral insertion and removal of a tool means into and from the holder thereby making it unnecessary to move the machine or work piece to provide excess clearance. The tool holder includes a main body having a shallow tool cavity formed in one end thereof for receiving the tool means. A locking element having a u-shaped collar is rotatably mounted to the main body for clamping the tool means within the tool cavity. The u-shaped collar defines a tool slot having a tool slot opening which extends from the side of the locking element. When the locking element is in an unlocked position, the tool slot opening aligns radially with the open side of the tool cavity to permit lateral insertion and removal of the tool means into and from the cavity. When the locking element is rotated to the locked position, tool slot opening is moved out of alignment with the open side of the cavity thereby preventing removal of the to tool means.
