The invention belongs to the field of metering equipment which is characterized by using a mechanical method, and particularly relates to a die-casting fitting hole detection tool. The die-casting fitting hole detection tool comprises a detecting table, a center pillar and a plurality of measuring pillars. The center pillar is arranged in the middle part of one face of the detecting table, the measuring pillars are arranged on the circumference using the center pillar as the original point, and the measuring pillars are matched with holes of a standard die-casting fitting. By the aid of the die-casting fitting hole detection tool, whether the positions and the sizes of the holes of the die-casting fitting meet a criterion or not can be rapidly detected at one time.
