The Milwaukee M12 FUEL™ 1/2 in. Drill/Driver is a compact bare-tool cordless drill built for lighter weight and tighter-space access than Milwaukee's larger M18 options. It uses a POWERSTATE brushless motor, a two-speed gearbox, and a 1/2 in. all-metal ratcheting chuck, with a body length of 5.95 in. and listed weight of 2.5 lbs. The tool is part of the M12 battery platform and is sold without battery or charger. The box includes the drill/driver and a belt clip, making it a straightforward option for buyers already using Milwaukee's 12V lineup.
Does the 3403-20 come with a battery or charger?
No. The 3403-20 is a bare tool. It includes the drill/driver and belt clip only, so M12 batteries and a charger must be supplied separately.
Is the 3403-20 meant for compact everyday drilling and driving work?
Yes. Milwaukee positions it as a subcompact drill/driver, and its 5.95-inch body length is aimed at tight spaces, lighter carry weight, and routine drilling and fastening work.
How heavy is the 3403-20?
Milwaukee's product overview calls it out at 2.5 lbs. That lighter build is one of the main reasons to choose it over larger 18V drill platforms.
What chuck does the 3403-20 use?
It uses a 1/2 in. all-metal ratcheting chuck. That gives it broader bit compatibility than many smaller compact drills while still keeping the tool size down.
Is this a good option if I already use Milwaukee M12 batteries?
Yes. The 3403-20 is best suited to users already on Milwaukee's M12 platform because it is sold tool-only and designed around the 12V battery system.
Does the 3403-20 include hammer-drill or ONE-KEY features?
No. This model is a standard drill/driver without hammer mode or ONE-KEY connectivity. It is intended as a compact drilling and driving tool rather than a masonry or connected-tool variant.
