ABSTRACT:
For enlarging the bore in a workpiece, the present invention provides a collar that can be secured to the workpiece with a plate rotatably mounted on the collar. A handle supports a housing in which a cutting tool is rotatably positioned. The cutting tool extends through a slot in the plate so that the handle may move the cutting tool from a first position within the workpiece and spaced from the bore thereof to a second position in engagement with the bore that is to be enlarged. Further rotation of the handle moves the cutting tool concentrically about the axis of the workpiece so that the bore may be enlarged to the desired size. Adjustable stop means are provided for accurately determining the second position of the cutting tool prior to the cutting tool being moved circumferentially. Various adapter means of different sizes may be employed for utilizing the present invention with workpieces having different, correspondingly sized, diameters.
