THIS 60V MAX* Mixer/Drill with E-CLUTCH System has over 2x the power of our corded mixer, allowing it to easily mix thin-set and tile mortar, as well as fiber reinforced concrete***. In addition to mixing, the powerful brushless motor allows the mixer to tackle demanding drilling applications. In order to improve control, the Mixer/Drill has the 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.
