ABSTRACT:
A boring tool is disclosed for machining holes in various materials which comprises a one piece body have a plurality of cutting members secured thereto in circumferentially spaced relationship. The cutting members are designed so as to enable them to be interchanged between a variety of different diameter bodies, the number of such cutting members increasing with greater diameter bodies. The body is provided with mounting surfaces positioned in such a manner so as to automatically accurately locate the cutting elements with respect to the body and to substantially eliminate any shear loading on the fastening elements securing the cutting members thereto thereby enabling use of only a single fastener element to secure each of the cutting members to the body. The cutting members are preferably circumferentially and radially spaced relative to each other so as to substantially balance the cutting loads thereby assuring positive accurate hole formation.
