Overview
Drawing up to 4 amps and reaching 1,550 RPM, the Milwaukee 3403-20 is a battery powered drill weighing 2.1 pounds inside a compact 4.1 by 6 by 8 inch body.
At 2.1 pounds this sits toward the lighter end of drill drivers, which helps with overhead work and extended use without arm fatigue. The 1,550 RPM top speed is modest compared to high speed drills, suggesting it is tuned more for driving and general drilling than fast hole boring in metal.

Who it's for

Performance notes
At 4 amps and 1,550 RPM, the motor is set up for controlled drilling and driving rather than high speed boring. The compact 4.1 by 6 by 8 inch footprint and 2.1 pound weight make it easier to maneuver in tight spaces than larger corded drills.
