Makita Max XGT 1/2" Square Impact Wrench Kit w/Detent Anvil, 2.5 Ah features the powerful 40V max XGT® brushless cordless 4-speed 1/2" square drive impact wrench with detent anvil, designed to deliver superior fastening control i for automotive, installation, and fabrication trades. Equipped with a Makita-built brushless motor, this tool provides an impressive 465 ft.lbs. of nut-busting torque and 260 ft.lbs. of fastening torque, outperforming similar impact wrenches in heavy-load applications. The 4-speed power selection switch allows precise fastening control across a wide range of tasks, while three forward and three reverse auto-stop modes enhance efficiency by stopping the tool once the fastener is adequately loosened. A full-speed mode reduces trigger pull to quickly reach maximum speed, and the compact 5-5/8" length makes it for working in tight spaces. Built with Makita’s Extreme Protection Technology (XPT™), this impact wrench is engineered to resist dust and water infiltration, ensuring durability in harsh job site conditions. The reinforced gear housing further enhances its toughness for demanding environments. The XGT system integrates advanced brushless motor engineering, intelligent digital communication, and multi-layer contact interfaces to optimize performance and deliver up to twice the sustained power under heavy loads. Additionally, the digital communication actively monitors and protects against overload, over-discharge, and overheating for extended tool life. Compatible with Makita 40V max XGT® lithium-ion batteries, this tool supports high-current demands with impact-resistant battery rails and fast, efficient charging via the XGT Rapid Charger (batteries and charger sold separately).
