I picked this drill up at Home Depot where the display and box said "Drywall and Deck" Drill. Now I was buying the drill to do some framing 2x4 to 2x4's with 2 1/2 screws. I found that the drill bit would bounce around and spin in the screws at the slightest provcation. I ended up pre-drilling each hole. Even still slow or fast it would bounce out and begin the stripping. Oddly about every 4 screws zip in one would go. I finished the job. My 14.4 Dewalt cordless drove them in flawlessly. I even tried the same bit in this one and no luck. I think the problem was the degree of speed was difficult to control and the drill over rev'ed. Larger treaded drywall screws were no problem. This is not a deck screw drill.
