10 Best Impact Wrenches 2025 in the United States

The Milwaukee M18 FUEL 18V impact wrench is a powerhouse in the cordless category, offering up to 2000 ft-lbs of torque, which is among the highest you'll find for this type of tool. It uses a 1-inch drive size that suits heavy-duty applications like automotive lug nuts and industrial tasks. The brushless motor paired with two 12.0 Ah lithium-ion batteries provides excellent runtime, capable of handling around 120 lug nuts on a single charge, making it very productive for extended jobs. This wrench also stands out with its ONE-KEY technology, allowing users to set exact torque limits to avoid over-tightening, which adds precision and protects your work.

The 4-mode drive control lets you adjust speed and power to fit different tasks, which is helpful since not all jobs need full torque. Ergonomically, the D-handle design combined with a removable, adjustable side handle and a lanyard loop helps manage its fairly heavy weight of 23.2 pounds, improving control and comfort during use. The built-in LED lights brighten the workspace well, reducing shadows where you’re working. One downside is its weight, which might be tiring for prolonged overhead use or for users who prefer lighter tools. However, the rugged build and rubber overmolds increase durability and grip comfort.

It includes two high-capacity batteries and a rapid charger, so downtime is minimized. This impact wrench is best suited for professionals or serious DIYers who need a reliable, high-torque tool with smart features for heavy and precise fastening tasks.

The impact wrench features a 4-mode speed setting and a variable speed trigger, allowing for better control in different applications. Additionally, the Precision Wrench control helps prevent overtightening and fastener run-off, which can be beneficial for both novice and experienced users. The BATTERYGUARD feature aims to reduce wear and tear on the battery, enhancing its longevity. An on-tool LED work light is included to illuminate dark workspaces, which is a helpful feature in low-light conditions.

Weighing 7 pounds, the tool is relatively heavy, which may lead to fatigue during extended use, but the ergonomic design aims to offset this to some extent. The plastic construction may not be as durable as metal alternatives, and the absence of an included battery adds to the cost. It comes with a 3-year limited warranty, 1-year free service contract, and a 90-day money-back guarantee, providing peace of mind. This tool is ideal for both professional and DIY enthusiasts looking for a reliable and powerful impact wrench.

With an impressive torque output of up to 1,100 ft-lbs for fastening and 1,600 ft-lbs for nut-busting, it excels in heavy-duty applications. The brushless motor contributes to its efficiency and longevity, making it a reliable choice for both professionals and serious DIYers. Weighing in at 5.94 pounds and measuring 7.6 inches in length, it strikes a balance between power and portability, although some users might find it slightly heavier compared to non-brushless alternatives.

One of the standout features is the AUTO SHUT-OFF control, which limits torque to 50 ft-lbs for hand-tight fastening. This helps prevent overtightening, making it suitable for delicate tasks where precision is key. Additionally, the Bolt Removal Control in Mode 4 enhances usability by allowing full torque output initially, then reducing RPMs after loosening the bolt to prevent fastener drops, which can be a real convenience on the job.

This product is sold as a tool only, meaning it does not come with batteries or a charger. This could be a downside for users who don’t already own compatible Milwaukee batteries. Also, while the weight and ergonomic design are manageable for most, those with smaller hands or less upper body strength might struggle during prolonged use.
