PROBLEM TO BE SOLVED: To enable suppression of burrs without reducing the strength of a tip cutting edge.SOLUTION: A cutting tool for grooving work comprises: a rake face 10 provided on a tip part upper surface 4 of a tool body 2; a tip cutting edge 11 provided at the tip edge of the rake face 10, to which cutting edge processing is applied; and side cutting edges 12 provided at both end edges of the rake face 10 so as to be continuous to the tip cutting edge 11, to which the cutting edge processing is applied. Cutting edges for deburring are formed at positions that are both side edges of the tool body 2 in a width direction and are adjacent to the side cutting edges 12. |
