The DEWALT® 60V MAX* Mixer/Drill with E-Clutch® System has over 2x the power of our corded mixer allowing it to easily mix thinset, tile mortar, and fiber reinforced concrete†. In addition to mixing, the powerful brushless motor allows the DCD130 to tackle demanding drilling applications. In order to improve control the Mixer/Drill has anti-rotation E-Clutch® System, which offers technology capable of detecting the motion of the tool. This feature senses the motion of the tool and shuts it down if necessary. The red indicator LED illuminates when the E-Clutch® System is engaged.
