A tapering tool having an expandable collet over which the end of a fiberglass pipe is received incorporates a mechanism to lock an expandable collet in a fixed position to prevent same from expanding outwardly and becoming tightly wedged against the interior of the pipe during the cutting cycle. The tapering tool further includes a radially-fed cutter blade arrangement which progressively draws the cutter blade onto the pipe being tapered during the cutting operation.
