Summary: | An impact tool comprises an end-bit holding section (3a) and a driving source (2). The end-bit holding section is formed with a hole (3a) for receiving an end bit (12), the hole having a center axis defining an axial direction, the hole having one end in the axial direction functioning as an end-bit insertion opening (3c) for passing the end bit therethrough, the hole having a generally polygonal cross section perpendicular to the axial direction. The driving source is configured to rotate the end-bit holding section. An arc-shaped cutout (3g) is formed at each apex angle of the hole in proximity to the end-bit insertion opening such that the arc-shaped cutout has a largest arc dimension at the opening (3c) and the arc dimension decreases gradually from the opening toward another end of the hole in the axial direction. |
