description The utility model relates to the technical field of machining, in particular to a threaded type handheld air drill hole-making limiting device which comprises an air drill clamping end used for clamping an air drill and an adjusting end connected with the air drill clamping end through threads. The adjusting end can adjust the total length of the air drill clamping end and the adjusting end through thread rotation according to the length of the air drill and the thickness of a metal structural part, the stroke of the air drill in the drilling process is controlled, the connecting length of the adjusting end and the air drill clamping end can be freely adjusted through threads, and therefore the working stroke of an air drill bit is adjusted. By means of free adjustment of the overall length of the device, the stroke of the air drill during drilling is controlled, protection can be provided for other parts on the rear portion of the metal structural part, tool operation steps are simple and easy, the operation
