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.
