"The 18V LXT Lithium-Ion Brushless Cordless 4-Speed Mid-Torque 1/2"" Sq. Drive Impact Wrench with Detent Anvil, Tool Only (XWT18Z) 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 520 ft.lbs. of Fastening Torque and 740 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. Additional precision features include three forward and three reverse rotation auto-stop modes, and a full-speed mode function that reduces the trigger pull to reach full speed. Makita's proprietary hammer and anvil impact mechanism are manufactured using the best raw materials with the highest quality steel and unique heat hardening process for maximum fastening and driving power. The XWT18Z 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. 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."
