Abstract
A boring head with a longitudinal axis includes a leading cutting portion and a trailing portion. A pair of adjustable work engagement devices are releasably secured to the leading portion by individual fasteners. Individual mechanisms for adjusting the position of each of the work engagement devices in a first direction generally parallel to the longitudinal axis of the boring head, and individual mechanisms for adjusting the position of each of the work engagement devices in a second direction, generally transverse to the first direction, are provided. The first and second direction adjusting mechanisms are positioned coaxially of each other in the boring head. Each work engagement device is adjustable in the first and second directions individually and independently of the other.
