The Makita DTW701Z is a cordless impact wrench powered by an 18V LXT Li-Ion battery with a brushless motor, electric brake and handy LED job light. Compact and lightweight, the DTW701Z also has a ergonomic soft grip for comfortable operation. Variable speed control is provided by the trigger whilst variable speed mode can be changed to full speed mode simply by pushing a button. Because in full speed mode the trigger travel is shorter, the full speed is reached faster. The DTW701Z also features forward / reverse rotation and auto-stop system is available in both modes. There is also electronic 4 stage impact power selection.
