ABSTRACT:
A boring tool for use in a tool holder, such as a boring head, that is driven about a drive axis and includes a pair of parallel bores for mounting boring tools generally includes a body including a cutting edge and a pair of mounting shanks for mounting in the bores of the tool holder. Preferably, the mounting shanks can be mounted in either bore and the cutting edge is disposed on the body so as to be different distances from the driven axis depending upon in which bores the mounting shanks are mounted.
