This is a great addition to the home workshop or craft-room, for anyone who wants a truly convenient and space-saving drill-press substitute without the expense and weight and bother of adjusting drive belts. You set this device on your bench or table and secure it with bolts or C-clamps, and then use your own electric drill, drill-driver, or dremel tool (with which you're already familiar) to do the drilling or shaping. It has two reasons for deserving only three stars instead of five: (1) The instruction sheet is all pictures, and the pictures are neither reproduced well enough nor large enough to let the user actually see the small parts s/he's trying to put in the appropriate place. I got the thing put together, but I used to have a drill press, and I take full credit for my success. (2) The bolt that is supposed to join the two parts of a metal "arm" is the wrong size; if I used it instead of searching and searching for a shorter one, then the two parts would not be held tightly together and the main lever (what you pull down to lower the drill bit) would be shaky to use, and I'd feel no confidence at all about using this device; I would think it is a piece of cheap junk. But I persevered mightily despite the most unclear instruction sheet, and I did find a bolt of the right length somewhere, so I have a neat, lightweight and portable, very nice little thing to get holes of precise depths drilled absolutely perpendicular into whatever I am making and to hold a sanding drum or wire brush wonderfully steady while I shape or clean or polish something; and I can use a corded drill for prolonged work, a cordless drill for super convenience, and a dremel or rotary tool, too. I'm glad I bought it.[two weeks later: It hasn't fallen apart ☺, and I doubt that it will. But the collar-like opening into which one's drill is supposed to fit does not accommodate a Ridgid cordless drill, and there's no way to adjust it to get that drill to be held by this drill press stand. The OPENING is 42 MM or 1 5/8 IN IN DIAMETER with the 1-mm thick plastic collar (that keeps the drill from getting scratched) in place. My Ridgid drill's rubber grip for the keyless chuck will fit snugly into it, but that doesn't do any good because the grip turns when the drill is running, and that is all wrong because the drill is supposed to be held stationary while the chuck and the bit turn and make the holes. My old corded electric Skil drill will fit in the opening if I remove the plastic collar; my dremel tool will fit, too. So if your electric drill has a tubular or cylindrical part between the chuck and the motor housing (the fat, wide part), and this tubular part does not turn when the drill is on, and the tubular part is smaller than 1 5/8" in diameter, this drill press stand will work for you. If you have a dremel or other rotary tool, its smaller diameter will fit, and you'll have no problem. I'm still glad I have it, but I'll have to use an extension cord if I want to use it outdoors. Maybe only two stars now. . . .
