Overview

The Milwaukee M12 Subcompact Brushless 3/8" Drill/Driver Kit is a compact cordless drill kit built for drilling holes and driving fasteners in tight spaces. This is a drill/driver designed for drilling and fastening . Model Number 3401-22 . If you spend your day inside cabinets, between studs, above your shoulders, or moving from room to room on service work, this size matters. Milwaukee kept this tool short at 5.4 inches and light at about 2 pounds with the kitted battery, which makes it easier to control when you are working one-handed or reaching into awkward spots.

For performance, Milwaukee gave this subcompact drill a brushless motor rated at 350 inch-pounds of torque with a 2-speed gearbox. Low speed runs from 0 to 450 RPM for controlled fastening, while high speed runs from 0 to 1,550 RPM for faster drilling in wood and general installation work. That combination makes it a practical everyday drill driver for electricians, cabinet installers, maintenance techs, punch-out crews, and serious DIY users who want something smaller than a full-size drill but still capable enough for real work.

The hardware is set up the way most buyers want it. You get a 3/8 inch all-metal keyless chuck for durability, 12 clutch settings for better fastener control, and a variable speed trigger so the tool responds the way your hand tells it to. Milwaukee also built in an LED work light and a battery fuel gauge, which are small features until you are working in a dark corner or trying to finish one more task before swapping packs.

From a design standpoint, the biggest win here is balance. A lot of compact drills are short, but not all of them feel planted when you actually put a bit in material. This one is built around the M12 platform and sized to stay nimble without feeling toy-like. The premium rubber overmold helps with grip, the belt clip makes it easier to keep the tool on you during ladder work or service calls, and the under-2-pound working weight helps cut fatigue during overhead drilling and repetitive fastening.
