A unique boring bar is disclosed which comprises a body having a generally radially extending formed through it at one end. A slide member is axially slidably positioned within the body throughbore and a standard cutting tool is secured to the slide member. In addition, one end of the slide member is externally threaded and threadably cooperates with an annular dial. The dial is locked against axial movement with respect to the body so that rotation of the dial axially displaces the slide member with its attached cutting tool. |
