ABSTRACT:
A boring tool assembly is provided and has a cutting tool mounted on one end thereof and permits the boring of a straight hole through a member. The boring tool assembly includes a boring bar having integral guide members disposed thereon that follows behind the cutting tool and maintains contact with the machined surface just cut in order to keep the cutting tool in proper alignment. To permit the continued use of the boring bar after the outer diameter of the cutting tool has been reduced due to wear, each of the integral guide members are resiliently mounted on the boring bar. This permits the guide members to collapses inwardly to maintain a perfect fit with the pilot pore. This collapse inwardly of the guide members is important to maintain bearing contact of the guide members with the pilot bore if the hole being cut by the cutting tool reduces in size due to wear or if the cutting tool has been re-sharpened or replaced with a different cutting tool. A resilient member is bonded in respective slots between the bottom of the associated slot and the guide member to provide the resilient mounting of the hardened guide members to the boring bar.
