1. DEWALT DCF880HM2 20-volt MAX Lithium Ion 1/2-Inch Impact Wrench Kit

The DEWALT DCF880HM2 is a 20 volt cordless xi li-ion battery operated drill with a hog ring anvil. This unit came first on our list for a variety of reasons. First, you’ll notice how compact this drill is for a portable unit of its power. With a size of only 5’7″ from front to back, this power drill can fit in pretty much any space. In addition, the xi li-ion battery holds 33% more charge than standard packs.

The second reason why this unit came first on our list is the incredible power it offers for such a small package. There aren’t many cordless units out there that can offer 300ft/lbs of torque power. You’ll be able to remove eveything from rusted lug nuts to heavy suspension parts with ease.

This unit is perfect for anyone who is looking for a unit that can handle most tasks a pneumatic drill would without having to spend hundreds of dollars on a compressor. And at a price of around $250 on Amazon, it is also very reasonably priced when considering it’s specs. For all these reasons, we gave the DEWALT DCF880HM2 a 5 star rating.

2. AIRCAT 1150 Killer Torque 1/2-Inch Impact Wrench

The AIRCAT 1150 is a pneumatic impact wrench which offers an astounding 1,295 ft/lbs of torque power and 1,400 blows per minute making it the most powerful in its category. It also features a patented quiet technology that allows it to run under 86 decibels. It comes with a 2 year warranty from the manufacturer.

There is pretty much nothing this impact wrench can’t do. And with its size of only 7.5 by 2.8 inches, it is great for under the hood work as well as for taking bigger components apart.

It is also extremely light at only 4 pounds. This unit is probably the most powerful unit for its size. It is also very versatile with its variable speed settings and reverse rotation lever. The only reason we didn’t rate it number one is because it doesn’t offer the portability a wireless unit like the DEWALT DCF880HM2 does. Besides that, this unit is nearly perfect. This is why we give it a 4.8 out of 5 stars.

3. Ingersoll-Rand 231C 1/2-Inch Super-Duty Air Impact Wrench

The Ingersoll-Rand 231C is a hard hitting pneumatic drill equipped with a twin hammer impact mechanism. It also offers 500 ft/lbs of reverse torque and up to 350 ft/lbs of forward torque. It also features a maximum rotor speed of 8000 RPM delivering an astounding 1200 blows per minute.

This unit is extremely light at 5.8 pounds and is one of the most ergonomically designed unit we came across. It also offers great power for its size. It was able to remove tightly bolted nuts in seconds without any signs of struggle.

While it isn’t as powerful as the Aircat 1150, it is also a lot more reasonably priced at around $115 on Amazon. The only issue we had with this unit is the unusual controls which can be counter intuitive at first. Because of this and the lack of power compared to the Aircat, we gave this unit a score of 4.5 out of 5 stars.

4. DEWALT Bare-Tool DC820B 1/2-Inch 18-Volt Cordless Impact Wrench

Click here for more details

The DEWALT Bare-Tool DC820B is a 12 volt, 1/2 inch impact wrench capable of delivering 145 ft/lbs of torque power. It features a highly portable and compact design making it great for hard to reach areas. Its heavy duty impact mechanism provides respectable performance without any kickback making it a very comfortable unit to use for longer periods.

This unit, while being very sturdily built and rather powerful for its size still isn’t as powerful as the DCF880HM2 with only 18 volts of power and 145 feet per pound of torque. It might do the job for easier tasks, but you might have issues removing rusty nuts or suspension components with this unit.

This unit is perfect for a handy man that needs a portable unit to do some minor jobs around the house or car, but it isn’t as heavy duty as some other units in its category. But still, with its reasonable price and portability, we give it a 4.3 out of 5 stars.

5. BOSTITCH BTMT72391 1/2-Inch Impact Wrench

Click here for more details

The BOSTITCH BTMT72391 is an über powerful pneumatic drill which offers 500 ft/lbs of raw power making it suitable for a wide variety of jobs. It also features a twin hammer mechanism. This unit comes with a 3 year warranty from the manufacturer. It offers three different power settings as well as a full power reverse option which comes very handy when comes the time to remove stubborn bolts.

While this unit will handle pretty much anything you throw it’s way, we had to say that it was struggling to remove nuts that were bolted with 250lbs/ft of torque. However, it still did the job after it struggled a bit. With that said, it was able to handle small jobs like removing most lug nuts and heavier jobs such as RV and truck wheels.

It is also one of the most reasonably priced units on the market starting at only 83$ on Amazon, which makes it a great choice for anyone on a budget. We give it a rating of 4.2 out of 5 stars.

These were our choice for the top 5 best impact wrenches on the market. Before you go for a particular wrench, make sure that it fits your budget and your needs. Also make sure that it comes with a good warranty in case anything happens. All the units featured on this page come with a great warranty and can all be found for a reasonable price on Amazon, so we suggest you give these units a closer look before you make a decision.
