You get two tools in one when you buy this kit. Milwaukee's Magnum hammer drill can be used as a regular drill for boring in wood or metal, or it can be switched over for use as a hammer drill, allowing percussion carbide-bit drilling in concrete and masonry. You can feel the quality of this tool when you hold it--its reinforced nylon resin casing, which is lighter and stronger than metal, offers better heat dissipation and chemical resistance. We found the convenient keyless chuck on this model to have an impressively tough grip, even in the toughest concrete drilling applications.Of course, when a hammer drill is used in heavy-duty industrial situations, the brushes wear out quickly. Taking this into account, Milwaukee's Magnum drill conveniently comes with a removable brush cartridge system so you can change brushes in seconds (there are even two extra brushes stored inside). We also liked the Quik-Lok cord set, which makes it easy to switch cord lengths (if you have one of the optional cords). There's also a handy depth guide adjustment that makes it easy to repeat accurate holes. While the dual operation of this drill is a great feature, if you intend to use it primarily for wood and metal work, you may want to consider a drill designed for that purpose; the Magnum, because of its dual-action capability, is larger and heavier than standard drills. But if you're interested in a tool that can handle both applications, we think this is a great choice. --Tim Block
