Thanks to its competitively compact design, this drill is perfect for fitting within wall studs, cabinetry, electrical boxes and other tight spaces. Featuring an efficient brushless motor and a heavy duty 1/2" ratcheting metal chuck, the Worx Nitro drill driver is built for professional performance and superior bit retention. The 2-speed gearbox allows you to back off when high speed might damage your screws or materials. The 20V Power Share batteries provide clean, rechargeable power so you can drill and drive screws anywhere in the house or on-the-go.
