The Bauer right angle drill is a nice cheap alternative for sanding bowls. However, the output air at the base is directed outward, causing sanding dust to go everywhere. This deflector directs a bulk of the air toward the drill head, which in nearly all cases is going to move air towards the dust extractor instead of away from it. I removed the rubber bottom piece on my drill and simply hot-glued this on.
