Abstract
A shaft (2) of a deburring tool (1) has a distal end surface (5) orthogonal to its axis L, an annular connecting surface (6) extending in an X2 direction from an outer peripheral end of the distal end surface (5) toward an outer peripheral side, and an annular outer peripheral surface (7) extending parallel to the axis L from an end in the X2 direction of the connecting surface (6). The shaft (2) also has notches (8) at four locations in a circumferential direction. Each of the notches opens to the distal end surface (5), the connecting surface (6), and the outer peripheral surface (7). Each of the notches (8) has an inner wall surface (10) having a pair of opposed surface portions (11) and (12) opposed to each other in the circumferential direction. Each of the pair of opposed surface portions (11) and (12) extends in a radial direction around the axis L. The edges of the pair of opposed surface portions (11) and (12) are cutting edges (25).
