Bosch 14.4 V Impactor By Nicholas Harrell on Jan 08, 2008 - Updated Sep 18, 2011

Quite possibly the best screwgun I ever used. This impactor can run just about any kind of self tapping screw in any kind of material. Wood, metal, even concrete. I have personally used it to run a 3/8 head self tappings creen about 3 inches long into a 3/8 thick carbon plate, without breaking the head off the screw or ruining the tip on it. If you do any kind of sheet metal work, like putting together sheds and buildings, this is a must have. Also very good for running phillips and torx head screws in thicker woods, pressure treated or not. The warrenty on it too is great, as bosch handles batteries for 3 years. Easy to get repaired too at most stores. Im very glad with my purchase, and would buy another one in a heartbeat.
