ABSTRACT:
This invention relates to a tapered finishing reamer having an overall taper of about ten degrees and having only two teeth diametrically opposite one another. Each tooth is formed to present a negative cutting angle on the order of ten degrees leading a diameter extending between the apexes of the two teeth. The tapered body of the reamer between the two teeth being cylindrical in cross-section and forms guiding surfaces of slightly less diameters than the diameter through the apexes of the teeth.
