ABSTRACT:
A two piece boring bar, one piece of which provides a recessed free end to which a cutting bar extension member is attached. When a cutting element as a separated component is used it may be removably secured upon the free end of the boring bar extension by a clamp that in turn provides a conically shaped socket which receives the similarly shaped head of a connecting member, threadable into the end portion of the boring bar extension, outside the boundaries of the recess formed therein. The clamp is also provided with a bendable depending stud projectable into an aperture formed outside the recess in parallel relation to the threaded connection of the clamp fastener, for locating and maintaining the clamp in position prior to its clamping engagement with the cutting element.
