The Makita DTW700 Brushless LXT Impact Wrench combines high operational efficiency with high torque. Ideal for steel fabrication, steel erection or for automotive work. It has a trigger switch and can switch between variable and full-speed mode. The variable speed mode can be changed to full speed mode simply by pushing a button.
