Abstract

A boring tool head has a movable element which can be moved by means of an adjuster relative to a centerline. Attached to the movable element is a cutting tool which moves with the movable element. A hole which is slightly smaller in size than the desired hole is first bored with the boring tool head and its size precisely measured. The fitting of the invention is then clamped onto the boring tool head by means of a clamping lever. The fitting has a position sensor which abuts against the movable element of the boring tool head, an indicator being attached to the sensor which provides an indication of the sensor's lateral position. The indicator is set to zero and the boring tool head adjuster set to bring the movable element of the boring tool head, as indicated on the indicator, to the desired position for increasing the size of the initially bored hole to the desired precise dimension.
