Has anyone tried this attachment to the drill on the ice last year? I know most of all the brand name augers have a safety plate of some kind to prevent losing the blade down the hole if it comes loose. The manufacture suggests positioning the flattened sides in the chuck to match how it sits when tightened, but with all the torque does it still loosen up more often than not? Tightening it down with a chuck key rather than your hand on the collar was the way I always did it with electric drills. I have no time put in the cordless drill systems but plan on using the Milwaukee brushless lithium this year.
