Milwaukee has brought brushless-motor technology to its 12-volt platform with the new M12 Fuel compact drill/driver. Because of the added efficiency provided by the motor, the tool is the first 12-volt with a 1/2-inch chuck. It’s under 8 inches in length and weighs 2.9 pounds with the compact battery. It has an onboard fuel gauge and a built-in LED. The kit comes with two batteries (2.0 compact and 4.0 extended run), a belt clip, a charger, and a carrying case. Price: $180 (bare tool, $130). 800-729-3878. milwaukeetool.com.
