Features and Benefits:BL™ Brushless Motor delivers 240 ft.lbs. of Fastening Torque and 430 ft.lbs. of Nut-Busting Torque;Compact and ergonomic design at only 5-5/8" long;4-speed power selection switch (0-1,000 / 0-1,800 / 0-2,600 / 0-3,200 RPM & 0-1,800 / 0-2,600 / 0-3,400 / 0-4,000 IPM) for precise fastening control in a wide range of applications;3 forward and 3 reverse Auto-Stop modes for increased efficiency;Full speed mode function reduces trigger pull to reach full speed;Efficient BL™ Brushless Motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge;The electronically-controlled BL™ Brushless Motor efficiently uses energy to match torque and RPM to the changing demands of the application;Built-in L.E.D. light with an independent on/off switch illuminates the work area;Weighs only 4.0 lbs. with battery for reduced operator fatigue;Rubberized soft grip provides increased comfort on the job;Makita�s 18V LXT® Lithium-Ion Brushless Cordless 4-Speed 1/2" Sq. Drive Impact Wrench Kit w/ Friction Ring Anvil (5.0Ah) (XWT14T) 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 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 XWT14T 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.
