The Makita 18V LXT® Lithium-Ion Cordless 7/16” Hex Impact Wrench (model XWT01Z, tool only, batteries and charger sold separately) combines cordless high-torque fastening power with additional features that phone and power utilities demand. It’s part of Makita’s expanding 18V Lithium-Ion series, the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Makita 18V Lithium-Ion 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® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside. Speed, Capacity and Ergonomics The XWT01Z is a powerful and convenient substitute for air-powered and AC impact wrenches. The Makita-built 2-Pole Motor delivers a top no-load speed of 1,900 RPM and 2,200 IPM, with a full 325 foot-pounds of Max Torque for fast and efficient drilling and fastening into treated wood and utility poles. Consistent with all of Makita’s best-in-class impact tools, the proprietary hammer and anvil impact mechanism in the XWT01Z is manufactured using the best raw materials with the highest quality steel and unique heat hardening process for maximum fastening and driving power. Ease of Use Features The XWT01Z has an ergonomic grip and large rocker trigger switch for easier operation, and a single L.E.D. light to illuminate the work area. The design also features a jobsite-tested shock-absorbent handle to protect the battery housing for extra durability, a quick-change 7/16” hex chuck, and an oversize ring for added convenience. At 10-3/4” long and 7.8 pounds (with battery, sold separately), the XWT01Z provides superior balance and control. The XWT01Z is designed with features for electrical and phone utility workers who spend a big portion of the day working with 7/16" hydraulic impact wrenches. The XWT01Z provides the contractor with the speed and power they need to drill and fasten into treated wood telephone poles without rotational torque.
