Abstract
An improved tool and method for the machining (e.g., boring, cutting, grinding and the like) of a workpiece. The tool includes a body that can be connected in a cantilevered arrangement to a machine for rotating machining operations and has fluid distribution channels formed in the body in a predetermined arrangement. The tool also includes a machining surface and at least one bearing surface formed on the peripheral surface of the tool. Pressurized fluid is provided through the fluid distribution channels in use, which, enable creation of a fluid bearing between the tool and an opening in the workpiece which has been machined by the tool. In addition, the tool can also include additional fluid distribution openings for cooling and cleaning of machining surfaces.
