The Milwaukee 3404-20 is a subcompact 12V hammer drill/driver built for tight spaces. Its brushless POWERSTATE motor and REDLINK PLUS electronics make it the shortest tool in its class at 6 inches, with an all-metal 1/2-inch chuck and all-metal gearcase for durability. It runs on M12 REDLITHIUM batteries, which are sold separately, and shares the M12 platform with over 125 tools. It suits electricians, installers and remodelers who want hammer capability and a real 1/2-inch chuck in a small package, and it trades outright power against 18V drills for size and weight.
