This adapter is made by Clam, and attaches to a cordless drill. I use a 20V lithium ion DeWalt drill. My friend was drilling a hole with his 10" gas auger, while was drilling an 8" hole. It was just as fast as his. Although I have the small battery , I wish I had the bigger 20 V. I can still about 10-20holes with the 2 battery's. However ice thickness is a big factor in how many holes you get.
