The DEWALT 60V MAX Mixer/Drill with E-Clutch System has over 2X the power of our corded mixer, allowing it to easily mix thin-set, tile mortar, and fiber-reinforced concrete. In addition to mixing, the powerful brushless motor allows the DCD130 to tackle demanding drilling applications. To improve control, the mixer/drill has an 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 light illuminates when the E-Clutch System is engaged.
