The Makita DTW300Z is a cordless impact wrench powered by a 18V LXT Li-Ion battery. It’s key features include a brushless motor, electric brake and a handy LED job light. Both forward and reverse rotation is provided, with an auto-stop system available in both modes. It also has electronic 4 stage impact power selection. The DTW300Z offers variable speed control by trigger whilst the 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.
