Makita GWT04Z 40V max XGT Brushless Lithium-Ion 1/2 in. Cordless 4-Speed Impact Wrench with Friction Ring Anvil (Tool Only)


The 40V Max XGT Brushless Cordless 4-Speed 1/2 in. Square Drive Impact Wrench Kit w/ Friction Ring Anvil (GWT04Z, tool only) provides improved fastening control, ideal for automotive, installation, and fabrication trades. The Makita-built brushless motor delivers 465 ft-lbs. of Nut-Busting Torque and 260 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 GWT04Z features Makita's Extreme Protection Technology (XPT), a series of protective seals inside the tool. It is designed to improve a tool’s operation in harsh conditions by channeling water and dust from key internal components. Reinforced gear housing provides additional durability on the job site. XGT is a system of equipment, tools, batteries and chargers utilizing 40V Max Lithium-Ion batteries.
