DeWalt XTREME 12V MAX DCF801F2

“An impact can be beneficial when driving the larger screws. They are noisy however. But, since you already have the 12v DeWalt drill (the brushless xtreme one ?, or older model?), their 12v brushless xtreme impact is very nice and it has a setting to allow you to use it like a screw driver until enough resistance is encountered and then it goes into impact mode. It is a nice feature. Now since you will collecting DeWalt 12v drivers, don't overlook the 12v xtreme brushless screwdriver. It has a very good torque range and especially on the low end for driving in the smallest of Ikea furniture screws without stripping out the MDF crap. (If you don't have the 12v xtreme drill, the drill/impact can usually be had together in a kit with batteries and charger)”
