ABSTRACT:
A sleeve is axially aligned with the bore which is to be cut by a cutting bar rotated in the sleeve. The sleeve is placed and held in proper position by radially projecting brackets having holes in them. These holes are aligned with holes in a member having its holes in preselected positions remote from the axis of the bore. The sleeve also serves as a stop to prevent excessive forward or rearward longitudinal travel of the cutting bar by abutment with collars detachably secured at suitable positions on the bar.
