Abstract:
1. An apparatus for boring a hole with a cutting tool and a boring machine, comprising: an adjustable position tool holder having a first contact surface and including a cutting tool; a coupling element for coupling said tool holder to the boring machine, said coupling element being slidably coupled to said tool holder and having a second contact surface in sliding contact with the first contact surface, said tool holder being adjustable laterally within a range of positions relative to the coupling element; and means for applying a frictional force between the first and second contact surfaces which is sufficient to restrain the lateral position of the tool holder when the cutting tool is boring a hole, but which frictional force is insufficient to restrain the lateral position of the tool holder when the lateral position of the tool holder is adjusted, wherein said applying means includes an electromagnetic solenoid.
