PURPOSE: A tap or drill jig is provided to reduce the fatigue of a worker by performing a work for processing a hole or a female screw without a tap or a drill. CONSTITUTION: A tap or drill jig (100) is composed of a base panel (110), guide bars (122), sliders (123), a holder (124), and a pressing lever (130). The guide bars are formed on the top surface of the base panel and have elastic bodies (121). The sliders face the guide bars and are vertically moved when the elastic bodies are stretched. One side of the holder is coupled to the guide bar, and the other side is coupled to the sliders to fix a tap or drill. The pressing lever is installed on the top of the holder and presses the holder. |
