I must admit I am surprised with this tool. I tried a IR version that is very similar but no variable speed. This drill not only has variable speed control, you can even drive wood screws at the lower speeds and it has plenty of power. You must have variable speed to drill in steel, trying to drill @ 2000 rpm in steel is just a recipe for disaster. You would surely wind up with a burnt up drill bit and the metal you were trying to drill would be too hard to drill with anything! I am a 30+ year auto mechanic and I have used my share of air tools, I still have many decades old air tools that still work and many are CP. I expected them to be going down in quality as so many things are today but this tool is well made, part composite but mostly metal. Many reviewers have been disappointed with the chuck, although mine seems fine, no missing teeth or loose key fit, it also doesn't appear to be the best chuck. I have an old CP 3/8" pistol type air drill that has a commercial Jacobs chuck and although it is very worn but you can see the huge quality difference. In automotive or any hard use I believe the chuck will most likely be the first thing to fail. These drills are obviously designed to fit tight spaces and that it does that well, 3 1/2" high at chuck I would highly recommend this drill. It is made in Taiwan if that is a concern for you...
