Dewalt DCD803B 20V MAX ATOMIC Multi-Head Drill / Driver – Tool Only

The DEWALT DCD803B 20V MAX* ATOMIC Multi-Head Drill/Driver is a compact, high-performance solution built for professionals who need flexibility, power, and control in tight or awkward spaces. Designed with a brushless motor delivering up to 569 Max Watts Out (MWO), this cordless drill/driver includes four interchangeable heads: a 1/2″ metal chuck, 1/4″ hex quick release, right-angle, and offset attachments. Each attachment connects using a secure drop-in system and features a yellow safety collar that confirms the head is locked in place, making it easier to switch between applications with confidence on the jobsite.

Ideal for tight quarters, overhead tasks, or jobs with limited tool clearance, this drill/driver stands out with its short 4.91″ tool body and variable speed (0–450 / 0–1650 RPM) two-speed transmission. The ATOMIC platform balances power and size, giving contractors, maintenance workers, and tradespeople up to 15% more power over previous models and a performance edge over the competition. From cabinetry and framing to electrical or HVAC installs, this tool gets into spots where standard drills can’t—while still delivering pro-grade torque and bit retention.

Note: Battery and charger are sold separately.
