Key Features
Compact Driving PowerThe Milwaukee M12 FUEL 1/4″ Hex 2-Speed Screwdriver packs up to 325 in-lbs of torque into a short 6.6 inch body, so you can drive fasteners in cabinets, panels, and other tight spots without dragging out a larger drill. 2-Speed ControlWith a 0 to 400 RPM low range and 0 to 1,700 RPM high range, you can slow down for controlled fastening or step up the speed when you need to move through repetitive screwdriving work faster. Built for Daily UseThe POWERSTATE brushless motor, REDLINK PLUS electronics, onboard fuel gauge, and LED light make this a more jobsite-friendly cordless screwdriver for users who want runtime, protection, and better visibility in real working conditions.
Overview
The Milwaukee M12 FUEL 1/4″ Hex 2-Speed Screwdriver, Model 2402-20, is a compact cordless fastening tool built for users who need more control and less bulk than a full-size drill. This is a cordless screwdriver designed for fastening screws and small fasteners in wood, metal, and general construction materials. If you already run Milwaukee’s 12V platform and want a bare tool that is quicker and easier to manage for repetitive driving work, this is the one that makes sense.
What matters most here is the balance between size and output. Milwaukee rates this tool with up to 325 in-lbs of torque, along with a 2-speed gearbox that runs at 0 to 400 RPM on low and 0 to 1,700 RPM on high. On the job, that means you can stay controlled when you’re setting cabinet hardware, trim screws, electrical devices, or lighter duty construction fasteners, then shift up when you need to run screws faster. The 15 clutch settings also help keep you from overdriving fasteners when finish quality matters.
The compact layout is a big part of why this tool stands out. At 6.6 inches long, it is easier to fit between studs, inside casework, under sinks, and in mechanical spaces where a larger drill gets awkward fast. The 1/4 inch hex quick-change chuck keeps bit swaps simple, which is exactly what you want when you’re bouncing between pilot bits, driver bits, and specialty fastening accessories. This is a screwdriver first, not a do-everything compromise tool, and that focused design is what makes it useful.
Milwaukee also built in the features that matter over a long workday. The POWERSTATE brushless motor is there for efficiency and service life, while REDLINK PLUS intelligence helps manage overload protection and tool performance. Add the onboard fuel gauge and built-in LED work light, and you get a tool that is easier to trust in dim corners, above-ceiling work, punch lists, and finish phases where you’re constantly checking battery status and visibility.
For platform users, compatibility is straightforward. This bare tool runs on the Milwaukee M12 battery system and works with all M12 batteries and chargers. That makes it a strong add-on for anyone already carrying M12 installation tools, inspection tools, compact lights, or service tools. If you are already invested in M12, adding this screwdriver is usually cheaper and more practical than stepping up to a bigger tool that you do not need for light to medium fastening.
This Milwaukee cordless screwdriver is a good fit for electricians, HVAC techs, maintenance crews, cabinet installers, remodelers, and serious DIY users who want a compact driver for controlled fastening. It is especially useful when you are working overhead, inside finished spaces, or anywhere a lighter, shorter tool reduces fatigue. If your work is mostly screwdriving and precision fastening, this is the smarter pick than carrying a heavier drill all day.
Compact Size That Actually Helps on the Job
This is the kind of fastening tool you reach for when a larger drill feels like overkill. The short body and hex bit interface make it faster to handle in tight spaces and easier to carry through finish work, service calls, and repetitive punch-list tasks.
