Tired of stubborn rusted nuts, low work efficiency, sudden battery drain, dim narrow working spots, fragile tools, rigid speed control and incomplete kits? This 1/2 inch cordless impact wrench solves all your repair frustrations at once. Built with a 21V premium brushless motor, it delivers 1500Nm torque and up to 3500 RPM, installing truck wheel bolts in just 3 seconds and raising efficiency by 90% over manual wrenches, ideal for car and pickup tire removal, auto maintenance, industrial construction and home DIY for both professionals and daily users. It includes two 21V 4.0Ah batteries to avoid work downtime, perfect for tire shops and long on-site tasks. The fast charger fully charges in 2 hours and hits 80% power in 30 minutes, with indicator light and cordless design for easy portability. The built-in LED light auto turns on when triggering and stays on around 20 seconds, lighting up dark tight areas under vehicles and wheel wells. It features simple start, safety lock to prevent accidental activation and one-touch forward reverse switch for effortless control. Made of premium tungsten steel and alloy, it gains 60% higher impact resistance with great wear resistance; lightweight aluminum head reduces hand fatigue, while TPE non-slip grip and shock-absorbing cover ensure stable use even in oily environments, with a lifespan over 10000 cycles. One-key forward reverse switching is supported, and intelligent reverse brake slows down automatically once nuts loosen, stopping fasteners from flying away and protecting bolt threads for safer work. Three speed modes of 2500, 3000 and 3500 RPM can be adjusted freely to match different tasks, saving battery and avoiding part damage. The all-in-one kit includes impact wrench, sockets, extension bar, charger, dual batteries, tool box and user manual, ready to use directly with no extra accessories needed.
