Abstract: A hole saw accessory device that is used with a conventional drill chuck. The device includes a mandrel assembly that includes a tubular member and a locking assembly slidably mounted thereon. The locking assembly is locked against a ring member that is integrally built on one end of the tubular member. An arrowhead drill is used and the mandrel assembly is allowed to slide over a portion of the shank of the drill so that the slug of wood cut out by the conventional hole saw is easily ejected.
