Overview
The Milwaukee 3403-20 draws 4 amps and tops out at 1550 RPM, covering a wide range of drilling and driving tasks. At 2.1 pounds it is noticeably lighter than full-size Milwaukee M18 drills, improving comfort for extended overhead work and tight-space installs.
With 197 reviews at a 4.6-star average and about 100 units sold per month, the 3403-20 has consistent real-world validation. The $109.86 price places it below the 2903-20, making it a logical entry point into Milwaukee's drill lineup for buyers who do not need maximum torque.
The compact body dimensions at 4.1 x 6 x 8 inches confirm this is a smaller-format Milwaukee drill, suited to finish work, cabinetry, and everyday trades tasks where reduced size aids maneuverability.
