PURPOSE: A jig for processing holes is provided to reduce time required for processing a plurality of hole at predetermined depth and to improve the productivity of a hole processing with a drill. CONSTITUTION: A jig for processing holes comprises a body member(200), a processing guide member(300), an elastic member, and a moving distance controlling unit(500). One side of the processing guide member guides the body member to be moved and the other side of the processing guide member is formed to make a drill edge penetrate through. The elastic member is formed between the body member and processing guide member. The moving distance controlling unit is connected to the body member and the processing guide member to make the depth of holes formed in the workpiece by the drill edge uniform and the body member move for a predetermined distance.
