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.

§ FAQ

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.
