ABSTRACT:
A machine tool includes a driver, a tool holder, and a locking device in the form of, for example, an alignment collar. In use, the machine tool carries a tool, such as a surface refinishing bit, which may be lowered into a workpiece bore, such as a cylinder head valve seat, and subsequently rotated by a machine spindle for resurfacing the bore. The machine tool receives a pilot shaft placed in a reference bore associated with the workpiece bore. The pilot shaft functions to ensure general alignment of the machine tool cutting axis and the refinishing surface.
