Core Performance & Features The Milwaukee 2503-20 M12 Sub-Compact Drill/Driver is powered by a POWERSTATE Brushless Motor, delivering 0-470 RPM for high-torque applications and 0-1,650 RPM for fast drilling. This compact cordless tool delivers a maximum torque of 45 Nm (approx. 400 in-lbs) for fastening and up to 60 Nm (approx. 530 in-lbs) for drilling tasks. The all-metal 10mm keyless chuck provides secure bit retention and durability. A 13-position mechanical clutch offers precise torque control to prevent overdriving screws in delicate materials. REDLINK Intelligence provides real-time communication between tool and battery for optimized performance and overload protection. An integrated fuel gauge displays remaining battery charge, and a built-in LED work light illuminates dark work areas. Bare tool only — battery and charger sold separately.
