摘要
A cross hole deburring tool which performs rotary cutting on a cross hole burr occurring on a cross ridgeline part between a through path and an inner circumferential surface of a spherically-shaped hollow part. A tool main body includes a tip part and a shank, and the tip part has a shape obtained by setting a diameter axis of a circle, setting an eccentric axis parallel to the diameter axis and away therefrom by a predetermined eccentric distance, setting a closed region in a bow shape formed of a line segment obtained by cutting the eccentric axis by the circle and a minor arc on the circle by defining this line segment as a chord, setting an outer surface shape of a bow-shaped solid of revolution formed by rotating this bow shape about the eccentric axis, and taking this outer surface shape as the shape of the tip part.
