• said tool body having a plurality of holes formed in the outer peripheral surface thereof and extending radially inwardly thereof, each of said holes being displaced axially rearwardly of said tool body from a respective one of said mounting recesses, each of said holes having an outer portion having an inner wall and opening to the outer peripheral surface of said tool body and an internally threaded portion extending radially inwardly of said tool body from said outer portion;
• (b) a plurality of indexable cutter inserts each releasably secured to a respective one of said mounting recesses, each of said cutter inserts having a face held in contact with said abutment face of a respective one of said mounting recesses;
