Abstract
A cutting tooth is carried on the outer end portion of a shaft which is eccentrically mounted within a power-rotated boring bar and which may be selectively turned within the bar to enable the tooth to be adjusted between an inactive retracted position and an active cutting position. By sliding the shaft in one direction, serrated rings mounted on the outer end portion of the shaft and within the outer end portion of the bar may be uncoupled to permit turning of the shaft. When the shaft is slid in the opposite direction, the rings are recoupled to establish a torsionally stiff rotational drive to the tooth by way of the outer end portions of the bar and the shaft. Turning of the shaft to adjust the tooth to its cutting position also effects outward adjustment of support pads for maintaining the outer end portion of the bar in a stable radial position during the boring operation.
