<p>A retraction tool (10) for removing the shank of a tool holder from a base block mounting (14) includes an elongate threaded member having a hook (50) threaded on one end thereof. The hook has a hook end for attachment to a receptacle in the forward end of a tool holder. A hammer (74) moveable along the length of the elongate member impacts against the stop for pulling said tool holder from the base block mounting. In the preferred embodiment, the receptacle in the tool holder is a hole having an axis at an angle of 45 to 90 degrees to the axis of the axial bore of the tool holder. When the receptacle hole has a diameter equal to that of the axial bore, a worn tool can be inserted in the receptacle hole and the worn tool can be struck with a hammer as an optional extraction device.</p> |
