PURPOSE: An auxiliary processing device of a hole is provided to improve the working efficiency and convenience by guiding the processing position of the hole and the forward direction of the drill accurately, and to prevent the failure rate by processing the hole precisely. CONSTITUTION: An auxiliary hole processing device is composed of a body part(100) having a first support part(110), a connecting part(130) and a second support part(120), and a fixing part(200) having an operating handle and a screw extended from the center of the operating handle and engaged with a female screw hole(121). A drill insertion hole is formed in the first support part to insert the drill, and the connecting part is extended and bent perpendicularly in the end of the first support part. The second support part is bent perpendicularly from the end of the connecting part and arranged in parallel with the first support part. The female screw hole is formed in the second support part corresponding to the drill insertion hole.
