PROBLEM TO BE SOLVED: To provide a tool for efficiently cutting a face gear to be meshed with a helical gear.SOLUTION: When a circular tooth thickness of a tooth tip of a cutting edge part is represented as S, a circular tooth thickness on a virtual outside diameter of a tooth profile of the helical gear in a cross-sectional view perpendicular to an axis is represented as S, a helix angle on the virtual outside diameter of the tooth profile of the helical gear in a cross-sectional view perpendicular to the axis is represented as &bgr;, and a face width of the cutting edge part is represented as b, formula is satisfied. |
