Thanks for the link. That's interesting that there isn't any ball bearing in it. Last night my father and I were taking apart an older 12v Ryobi cordless drill to take a look at the transmission inside, and we found out the hard way that there is ball bearings in the 12v (non-hammer) model. Then again, the drill we took apart was almost ten years old, which may have explained the better quality.

I love the Dewalts, and I know that they are of a way better quality than the Ryobis. I just found this drill, and thought I would post it here because there may be some applications (non drive-train) where you could use a cheaper transmission. I was just looking around for a cheap source of a second transmission identical to the one we now have when I found this. Once we get a second one, I'd like to try using them on a Vex robot drivetrain. When that Vex robot hits 8.8 feet/sec, you'll see some serious stuff!
