Point blank: This is the best 12-volt drill/driver I've ever used. As powerful and versatile as it is small, Festool's C12 sets a new category standard. I tested it drilling small and large holes, driving various lengths of wood screws and Tapcons, and even mixing thinset. The C12 was a great tool at every step.
Out of the Box. The C12 is an impressive if unorthodox-looking tool. Its compact slide-on 1.3-amp-hour nicad battery exchanged nicely, the tool was well-balanced, and all switches were easy to reach and work. At 3 pounds 6.8 ounces, it's one of the lightest 12-volt nicad drill/drivers on the market. Its onboard bit storage is excellent: Instead of pinching driver bits in fingernail-bending metal clips, it holds them securely with magnets. To remove bits, slide them in the storage channel, up a ramp, and out. Top-notch design.
The tool also ships with a hex drive bit holder (finally!) and a keyless 1/2-inch chuck that are exchangeable using no tools. And, both chucks have bearing collars to protect work–very smart. Remove either chuck and the C12 also turns bits directly from the tool. I used the hex drive with Festool's magnetic bit holder the most. While I liked it, I'd get extras because the shank isn't compatible with standard 1/4-inch hex-drive accessories. The C12 also ships with an incredibly sharp 1/8-inch brad-point drill bit.
