Makita TW003GZ 40Vmax XGT Brushless 1/2″ High Torque Impact Wrench – Tool Only

The Makita 40Vmax XGT Brushless 1″ Long Anvil Impact Wrench Kit delivers massive fastening power with professional-grade precision, making it an ideal choice for the heaviest-duty applications. Offering up to 2,320 ft-lbs (3,150 Nm) of torque and 2,950 ft-lbs (4,000 Nm) of nut-busting torque, this battery-powered unit is designed to replace traditional pneumatic wrenches for tightening and loosening large diameter bolts. The long anvil and 1″ square drive provide extra reach and secure socket engagement, while the 3-mode automatic stop system in both forward and reverse rotation prevents over-tightening and damage to fasteners. With a variable speed trigger, selectable full-speed mode, and four impact power settings, this tool adapts easily to a wide range of fastening tasks.

Built with Makita’s XGT brushless motor technology, the impact wrench delivers high torque without sacrificing maneuverability. The vertical motor layout shortens the overall length for better balance and reduces reaction force at startup, making it easier to control even during extended operation. A ring-style LED light improves visibility while minimizing socket shadows, and the vibration-dampening rubber joint design helps protect both the tool and the battery connection from long-term wear. This kit includes two 40Vmax 5.0Ah batteries, a rapid charger, a side handle with 360° tool-free adjustment, and a heavy-duty 21″ tool bag for convenient transport and storage.
