The BATTERYGUARD technology aims to extend battery life, though it's worth noting that the battery is sold separately. Weighing 7 pounds, it is relatively heavy, which could be a concern for prolonged use. Ergonomics-wise, it aims to balance power and user comfort but might not be the best for everyone due to its weight. Durability is a strong point, backed by a 3-year limited warranty, a 1-year free service contract, and a 90-day money-back guarantee.

Considering its solid build, power, and the brand reliability of DEWALT, this impact wrench is well-suited for both professional mechanics and DIY enthusiasts dealing with lug nuts. However, the need to purchase the battery separately adds to the cost and might be a drawback for some users.

The TaskStar Cordless Impact Wrench excels in high torque delivery, offering a peak of 1200 N·m (886 ft·lbs), which is quite powerful for a range of demanding tasks including loosening or tightening lug nuts. It comes with two 4.0Ah batteries that ensure extended working time, and the fast charger can fully recharge the batteries in 1-2 hours. The variable speed settings (0-1700RPM/0-2500RPM/0-3300RPM) allow for precise control depending on the task, paired with a variable speed trigger for additional accuracy.

The Milwaukee 2967-20 M18 FUEL™ 1/2" High Torque Impact Wrench is a strong contender for anyone needing a reliable tool for lug nut applications. With a remarkable maximum fastening torque of 1,100 ft-lbs and an impressive nut-busting torque of 1,600 ft-lbs, it can tackle even the toughest lug nuts with ease.

One of its standout features is the AUTO SHUT-OFF control, which limits torque to 50 ft-lbs for hand-tightening. This helps prevent overtightening, which is particularly beneficial for users who might not have much experience working with impact wrenches. The Bolt Removal Control in Mode 4 is also a great addition, as it ensures that once a bolt is loosened, the RPMs decrease, minimizing the risk of dropping fasteners.

Additionally, while its power and features are impressive, some users might find it a bit more complex compared to basic impact wrenches.
