Milwaukee's M18 Compact Brushless 1/2 in. Drill/Driver Kit w/ 2 Batteries & Charger is built around the M18 cordless platform and includes two batteries and a charger to support continued workflow between charges. Brushless motor construction is designed to provide efficient power delivery while reducing routine motor maintenance associated with brushed designs. Its compact form factor makes the drill/driver practical for overhead work, cabinetry, framing, fixture installation, and other applications where a full-size drill can be cumbersome. The 1/2 in. chuck and adjustable clutch provide versatility for both drilling and screwdriving tasks, while the cordless configuration eliminates the need to work around a power cord.
