ABSTRACT:
The present invention relates to a relatively small hand-held tool for cutting grooves in the ends of small diameter pipe and for sizing the outside diameter for a predetermined length. More particularly the tool has a drive housing in which cutting blades are located and a pipe housing, pivotally connected to the drive housing, in which the pipe end is positioned. A coil spring, acting against both housings, provides the blade pressure on the pipe. Grooving is done by rotating the tool about the pipe.
