I have had a 110v casals mixing drill, Spanish company I think. I can't praise it enough its filthy but still going strong (12 years), never even had the brushes changed. It's been absolutely thrashed all its life even mixes sand and cement no probs, just wish I could find another. I love that periodic tap on the casing of a mixing drill with a hammer and watch all the dust bellow out, it's like beating the seats of the school bus.
