Abstract
An adjustable boring bar wherein the adjustment of the cutting end is provided by a prestressed internal bar bearing against the cutting end to selectively distort the boring bar in the direction of the cutting bit to compensate for wear. The adjustment is by means of rotation of the prestressed internal bar to direct the pressure of the internal bar against the boring bar and cutting bit in the desired direction.
