ABSTRACT:
A boring bar apparatus for removing material from the interior of a rigid structure through an elongated cylindrical opening therein. A bar mounted for rotation within the cylindrical opening carries a cutting head whose position relative to the opening can be independently varied radially and axially as the bar rotates. In this way, precision cuts can be made on otherwise inaccessible areas of the structure.
