PROBLEM TO BE SOLVED: To provide a groove cutting tool having high accuracy and low manufacturing cost in a cutting tool for processing an annular groove such as a groove for an O-ring on a flat surface. A base material for a groove cutting tool, the shank extending in a circular cross section from a center of the shank along a vertical central axis, and an end surface of the shank extending parallel to the central axis apart from the central axis. The removable base material of the cutting blade for groove cutting (hereinafter abbreviated as the cutting base material) and one end surface of the shank can be attached and detached at a position substantially symmetrical to the cutting base material with respect to the central axis. And an auxiliary member provided to assist processing of the cutting blade base material. A method of manufacturing a groove cutting tool, comprising a step of simultaneously processing the outer periphery of a cutting blade base material and an outer periphery of an auxiliary member of a base material of the groove cutting tool by grinding, and a cutting blade during the machining. And a step of measuring a distance between an outer circumference of the base material and an outer circumference of the auxiliary member, and a step of removing the auxiliary member after the outer circumference is processed into a predetermined size. And a groove cutting tool manufactured by this manufacturing method. [Selection diagram] Figure 1
