I've never used a drill on mine, but use and own a plethora of cordless drills of several makes, every day IMHO, the noise level will be the same, that wonderful crunching sound of grain getting ready to give up the goods.Just curious. What is the noise level running with that motor (or similar, since the Ale works isn't available) compared to using a cordless drill? I use a Bosch 18V cordless on my Malt Muncher 3 roll mill.
