摘要： The present invention discloses a tool assembly being capable of reducing considerably an axial length of a working member (tool), in particular, a length of a male spigot to be coupled with a coupling member and transmitting a torque to a working member without generating a loss by means of a secure coupling between a male spigot of a working member (tool) having a short length and a coupling member. A tool assembly according to the present invention comprises a tool (100) including a head (110) to be approached to a work-piece, a male spigot (120) extended from a rear end of the head (110) and a flange (150) formed at a border portion between the head (110) and the male spigot (120) and having a ring shaped flat rear surface; and a coupling member (200) consisting of a first section (210) having a cavity (211) formed on a central portion of a front side thereof for receiving the male spigot (120) and a second section (220) formed at a rear side of the first section (210) and connected to a driving means. The male spigot (120) has a tapered surface (121,122) formed on a side thereof, a through hole (212-1,212-2) communicated with the cavity (211) is formed on a side of the first section (210) of the coupling member (200), and an end of a coupling screw (412,411) coupled with the through holes (212-1,212-2) is capable of pressurizing the tapered surface (121,122) of the male spigot (120) received in the cavity (211).
