Makita’s 18V LXT® Lithium-Ion Brushless Cordless 4-Speed 1/2" Sq. Drive Impact Wrench w/ Friction Ring Anvil, Tool Only (XWT14Z) provides improved fastening control, ideal for automotive, installation, and fabrication trades. The impact wrench combines extended run time and speed control for unmatched fastening performance. It is powered by a Makita-built brushless motor for longer run time. The brushless motor delivers 240 ft.lbs. of Max Torque and 430 ft.lbs. of Nut-Busting Torque. 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 XWT14Z features Makita's Extreme Protection Technology (XPT™), a protective seal inside the tool. It is designed to improve a tool’s operation in harsh conditions by channeling water and dust from key internal components. It is part of Makita’s 18V LXT System. The LXT Cordless System, the world’s largest cordless tool system powered by 18V lithium-ion slide-style batteries, takes a user from power tools to outdoor power equipment to get the job done. Makita 18V LXT Batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. Batteries are sold separately. For improved tool performance and extended battery life, Makita created Star Protection Computer Controls™. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT Lithium-Ion Batteries with the star symbol on the battery indicating Star Protection inside.
