Summary: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. 【課題】先端切刃の強度を低下することなくバリを抑制することができるようにする。【解決手段】工具本体２の先端部上面４に設けられたすくい面１０と、すくい面１０の先端縁に設けられ且つ刃先処理が施してある先端切刃１１と、先端切刃１１に連なるようにすくい面１０の両端縁に設けられ且つ刃先処理が施してある側面切刃１２と、を備えている溝入加工用の切削工具において、工具本体２の幅方向両側縁であって側面切刃１２に隣接する位置に、バリ取り用の切刃が形成されている。【選択図】図２
