Milwaukee 3453-21 M12 Compact Brushless 1/4″ Hex Impact Driver Kit (1) 2AH

Milwaukee’s 3453-21 M12 FUEL™ 1/4″ Hex Impact Driver Kit delivers subcompact size with serious speed for daily fastening. Measuring about 5″ in length, this cordless impact driver gets into tight cabinets, between studs, and overhead spaces where larger 18V tools struggle. The POWERSTATE™ brushless motor produces up to 1,300 in-lbs of torque with no-load speeds up to 3,300 RPM and 4,000 IPM, giving installers fast driving performance on structural screws, Tapcons, and hardware. Four Mode Drive Control lets users choose the right output for delicate starts or full-power driving, while REDLINK PLUS™ Intelligence manages heat and load to help maintain consistent performance.

A Tri-LED array surrounds the bit for maximum workspace visibility with fewer shadows, improving accuracy in low-light areas. Pair it with the included M12™ CP2.0 battery for an all-day, lightweight setup that fits easily in a pouch or service bag. As part of the M12 System, this impact driver works with 100+ compatible 12V tools, so crews can standardize on one compact platform for maintenance, install work, and punch-list tasks.

The short body improves reach in ceiling spaces and cabinets, while 4-Mode control adds finesse for small hardware and the speed to run longer screws when needed. Tri-LED lighting makes it easier to find driver slots and avoid cam-out, improving results in tight or dark areas. With a brushless motor and REDLINK PLUS electronics, the tool runs cooler under load and pairs well with the lightweight CP2.0 pack for long shifts.

Why Customers Choose the Milwaukee M12 Compact Brushless 1/4″ Hex Impact Driver Kit

Crews choose the 3453-21 because a cordless impact driver that’s truly compact saves time in real-world spaces—inside panels, under sinks, and between studs. The Tri-LED ring lights the fastener from all sides for cleaner starts, while 4-Mode Drive Control helps avoid stripped heads and broken screws. With 1,300 in-lbs on tap, the M12 impact driver handles anchors, cabinet hardware, and light structural screws without the bulk of a full-size 18V tool. Running on the M12 platform, teams keep packs and chargers consistent across drills, lights, and inspection tools, reducing carry weight and simplifying setup. The result is faster changeovers, better visibility, and dependable power in a compact package that fits the pace of daily install and service work.
