The 40V Max XGT Brushless Cordless 4-Speed High-Torque 3/4 in. Sq. Drive Impact Wrench w/ Friction Ring Anvil (GWT01Z, tool only) provides improved fastening control, ideal for automotive, installation, and fabrication trades. The Makita-built brushless motor delivers 1,510 ft.lbs. of Nut-Busting Torque and 1,330 ft.lbs. of Fastening Torque to out-power similar impact wrenches in heavy-load applications. Precise fastening control is achieved through the 4-speed power selection switch, which accounts for a wide range of applications. Three forward and three reverse rotation auto-stop modes offer increased efficiency when fastener is adequately loosened. The full-speed mode function reduces the trigger pull to reach full speed. The GWT01Z features Makita's Extreme Protection Technology (XPT)
