Best Hybrid: Bosch Freak GDX18V-1800B12 18-volt Cordless Impact Driver

Sometimes a tool that is required to do two things at once actually does one thing better than the other. This isn't the case with the Bosch Freak 18-Volt Impact Wrench. It’s both a driver and a wrench, and it makes quite an impact.

It uses ¼-inch hex screwdriver bits and ½-inch impact sockets. The practical tool quickly switches between screwdriver and nut-driver bits (as well as sockets), so you won’t have to search around for an adapter for the more complicated jobs that require different tools. The powerful brushless motor delivers a maximum of 1,800 in-lbs of torque and up to 4,200 impact-per-minute for professional power and impact.

The Freak comes with battery, charger, and soft case, as well as a belt clip to keep it near at hand.

Best for Lug Nuts: DEWALT 20-Volt Max XR Lithium-Ion 1/2 in. Cordless Impact Wrench Kit with Detent Pin Anvil

DeWalt 10V Max XR Lithium-Ion Cordless Impact Wrench Kit

Removing stubborn lug nuts can be a painstaking task, so you'll want to invest in a heavy duty tool that can get the job done quickly. Our top pick is the DeWalt 10V Max XR Lithium-Ion Cordless Impact Wrench because it has 2,000 in-lbs of maximum torque and a brushless motor that will extend its life. A ½-inch anvil with a dent pit makes the wrench resistant to breakage and the annoying shearing that so often comes with lug nut removal. It can handle drops from as high as 8 feet with its compact design and durable casing. This impact wrench also has an LED light with a 20-second delay for use in dark spaces.

Best Air: Ingersoll Rand 2235TiMAX Drive Air Impact Wrench

If you're looking for a high-performance tool that is lightweight but still able to pull off big jobs, the Ingersoll Rand 2235TiMAX Drive Air Impact Wrench is a great option. It has a well manufactured drive mechanism to put out serious spin ability with 1,350 in-lbs of torque. Ingersoll’s ½-inch air impact wrench is known for its power-to-weight ratio, as it weighs in at only 4.6 pounds and has a four-position power regulator (which makes the torque easy to adjust).

Best Quick Change: Chicago Pneumatic CP7732 ½-inch Stubby Impact Wrench

The Chicago Pneumatic CP7732 ½-Inch Stubby Impact Wrench is an absolute workhorse. It can easily maneuver tight spaces and it packs a powerful punch. It can strip pull out stubborn stripped screws or oxidized bolts that are squirreled away in an inconvenient location. If a bolt or lug nut is lodged in a difficult place, the user-friendly stubby impact wrench won’t hold you up as you grapple with finding a good grip on the handle. It has a one-hand operation trigger with three position settings that come in both forward and reverse. Plus, this tool works well for people who are left-handed and right-handed.

Final Verdict

The Milwaukee Fuel High Torque Impact Wrench (available at Amazon) is one of the most powerful impact wrenches for its size; it makes quick work of even the toughest nuts and bolts, letting you loosen or tighten them with ease. But if you merely need an impact wrench for simple tasks around the house or garage, and don’t demand the utmost in power and torque, you’ll find the Porter-Cable PCE211 (available at Amazon) is very reasonably priced and a great choice for the average DIYer.
