5.4. Brushless Motor Technology

This DEWALT drill features a brushless motor, which provides increased efficiency, longer runtime, and extended tool life compared to brushed motors. This technology contributes to the tool's ability to complete challenging projects with up to 40% more Unit Watts Out (UWO) versus the DCD796B when using a DCB205 battery or DCBP034 DEWALT POWERSTACK battery (sold separately).
