The tool changer in this invention is characterised by a draw bar which has a gripper on one of its ends and incorporates a tightener on the opposite end which is released on full retraction of the milling quill to release the draw bar, thus opening the gripper to release a tool holder from it. The released tool holder may be replaced with a new tool holder and the quill extended causing the tightener to be activated to tighten the draw bar to cause the gripper to be closed around the new tool holder.
