Plastic pipe chamfering tool

DETAILED DESCRIPTION A first object of the invention is to provide a single chamfering tool for multiple sizes of plastic pipe.
This has been accomplished by creating a chamfering tool body having various concentric circular grooves of different diameters which are shaped and sized to receive the square-cut ends of standard size plastic pipe.
Each circular groove has an associated cutting blade mounted transversely with respect to the circumference of the pipe in a recess on the outer surface of the main body and positioned so that as the tool is rotated about the square-cut end of a pipe inserted in its correspondingly-sized groove, a chamfer is cut on the outer circular edge of the pipe.
The problem of cuttings from the chamfered edge entering the interior of the pipe has been solved by maintaining the pipe end covered by the tool body during the chamfering process.
In order to further reduce the possibility of cuttings entering the pipe, the cuttings are expelled through the blade recess as they are shaved from the pipe edge.
The problem of over-chamfering is solved by the invention because cutting automatically ceases when the pipe end becomes seated in the groove.
