The disclosed embodiments include a rectangular jig tool that has a substantially rectangular body with a square cross-sectional shape, and this able to be held in a vice. The device has a number of features which enable the drilling of aircraft parts. First, the longitudinal slot is used to receive one portion of a part, and allow another portion to extend over a recess in the tool. When the drill passes through the part, it does not damage the tool because the recess accommodates. An optional clip-on feature is also provided which holds the parts in the longitudinal channel so that they are secured during drilling. Other parts are inserted such that they extend out away from a longitudinal slot in the tool for uninterfered drilling. Another features includes a longitudinal corridor/slit arrangement that allows a number of parts to be securely held and stick out from the device for drilling.
