Abstract: An adapter device holds a conventional ice auger and mounts the auger on a conventional cordless drill. A rigid elongated shaft has a first end adapted for retaining and operating an auger bit held thereon. A second end mounts on a cordless drill, which is a standard shape of a drill-attaching end of a bit for a cordless drill. A midsection between the two ends has a shield mounted thereon. The shield is larger than the auger and prevents the adapter device from falling through a hole made by the auger bit. The shield comprises an element, such as a rigid disc or rod, rotatably mounted on the elongated shaft so the shield will not spin when the elongated shaft and auger bit are rotating.
