The Milwaukee 3601-21P M18 Compact Brushless Drill/Driver delivers speed and control in a small, lightweight form for daily drilling and fastening. At just 5.7″ long and only 3.2 lb with the included battery, it fits overhead and between studs while keeping wrist strain down over a full day. A brushless motor, paired with REDLINK™ Intelligence and an M18 REDLITHIUM™ CP2.0 battery, provides up to 550 in-lb of torque and two speed ranges (0–500 / 0–1,700 RPM) to cover pilot holes, spade bits, self-tappers, and common fasteners. The all-metal gear case and 1/2″ metal chuck hold up to jobsite use and maintain bit grip under load.

This kit includes one compact 2.0Ah battery, an M18/M12 multi-voltage charger, and a contractor bag. As part of the M18 System, the 3601-21P works with 250+ compatible solutions so crews can stay on a single 18V platform for drilling, driving, cutting, and lighting around the site.

Why Customers Choose the Milwaukee M18 Compact Brushless 1/2″ Drill / Driver Kit

Installers choose the Milwaukee 3601-21P because a compact cordless drill with a brushless motor gives enough torque and speed for most daily tasks without adding bulk. The 1/2″ metal chuck holds up to step bits and hole saw pilots, while the two-speed gearbox helps start clean and then finish fast. On ladders and in ceiling spaces, the short 5.7″ length makes a difference—less snagging, better balance, and fewer missed holes. Staying on the M18 drill platform also means one set of batteries and a single M18 charger, so crews can move from drilling to cutting or lighting with fewer pack changes and less time walking back to the truck.
