A boring tool is disclosed and claimed herein that utilizes indexible and replaceable polygonal cutting inserts. The inserts are preferably triangular and are received in a slot in the forward, cutting end of a tool. A mounting plate is secured within the slot and provides rigidity for the cutting inserts. Adjustment means are provided which cooperate with the mounting plate to position the cutting inserts simultaneously at a predetermined position to set the cutting diameter of the tool at a predetermined amount. Cutting inserts are thus adjusted to provide the proper diameter cut with removal from the tool.
