Bosch is one of the premiere brands in the cordless drills market and this new (2010) compact and lightweight model doesn't disappoint. More driver than drill, the Bosch 12V Pocket Driver PS21-2A (starting at $105, Amazon) is powerful and fast, according to Bosch 12V Pocket Driver PS21-2A reviews. Tool Guyd says this short-nosed driver lives up to its advertising claims and surpasses the performance of its well-received PS20-2A predecessor. It also scores high in users' reviews on Amazon. Users rave about its 1.8-pound weight and 5.6-inch head, noting it slides into a pocket, fits into most any space, and doesn't cause hands to cramp. The battery's staying power draws applause in reviews, as does its ability to drive screws with ease and its precision control. But perfect this cordless tool is not. Users express a desire for a battery gauge, say the universal bit holder is in reality less than universal, and the slight delay after pressing the trigger (when the LED light goes on) takes some getting used to.
The Bosch 12V Pocket Driver PS21-2A features a variable speed trigger and two reversible speeds (0-350 rpm and 0-1,300 rpm), a 1/4" bit holder, and 20 clutch settings. The tool comes packaged with two lithium-ion batteries, a 30-minute charger, and a carrying case.
This model does OK as a drill but really shines as a driver. It boasts enough torque and speed to suit the needs of home hobbyists and DIYers as well as seasoned professionals, including maintenance mechanics. If your project plans call for heavy use of screws, this one's for you.
