the best impact wrenches

Last updated on March 19th, 2023 at 12:29 am

Have you ever had to loosen a rusted nut with just a simple spanner or simple power drill with a socket attachment? No doubt, you know how it went. Sometimes, you either end up stripping the nut or damaging the socket wrench without even loosening the rusted nut.

A simple solution to prevent all that from happening is to use an impact wrench.

If you work on vehicles, tractors, engines, ships, construction or other types of heavy-duty machinery with nuts and bolts holding parts together, then you must already be familiar with the function of an impact wrench.

Unlike a regular power drill, an impact wrench is designed to deliver a sudden high torque output measured in ft-lbs through the output shaft called the anvil.

This high torque output applied on a nut or bolt by means of a socket wrench allows the user to loosen stuck or rusted lug nuts and bolts that will be extremely difficult or impossible to loosen with a regular socket.

Just like many other power tools, impact wrenches come in different types based on their power sources such as pneumatic or compressed air powered, cordless electric or battery powered and corded electric.

Back in the days, pneumatic or air powered wrenches where the go-to tools for projects like this. However, since the early 2000s, cordless or battery powered wrenches have been coming on pretty strong.

They’re not only portable, but can now produce as much torque in ft-lb as air powered units. Without an air compressor, you can’t use a pneumatic impact wrench.

rusted nuts and bolts

That also means they’re limited to use in the workshop, because taking them out means you have to string along a bulky air compressor machine.

On the other hand, a cordless or battery powered impact wrench has none of those limitations. It’s very portable, and there’re many latest models that will produce as much torque as those air powered ones.

Apart from pneumatic and battery powered impact wrenches, there’re also hydraulic units which make use of high-speed hydraulic motors.

Hydraulic wrenches like this produce very high torque and have high power to weight ratio. You’ll find these in large construction sites like shipyards, automobile factories, and large repair shops where a suitable hydraulic supply is on standby.

With so many types of impact wrenches and even more number of tool brands producing them, choosing one for your own projects can be quite difficult and time consuming.

However, we’ve taken our time to review many of these impact wrenches and I’ve listed 5 of the best right here in this article.

Here’s my list.

Aircat 1778 VXL vibrotherm drive air impact wrench

While we talk about cordless battery powered impact wrenches, it will be a very huge mistake to forget about pneumatic ones because even though it’s a little inconvenient to use them due to their air compressor reliance and the messy air hoses, pneumatic impact wrenches have served the craftsman for years. They have a better power to weight ratio and they’re still very applicable till date.

Now, if you have a good air compressor in your garage and you’re in the market for an air powered impact wrench, one of the best ones I’d quickly recommend is the Aircat 1778-VXL with Vibrotherm drive.

It comes in 3 drive sizes. You’ll find a ¾ inch, ½ inch and 3/8 inch drive size. This one here is the ¾ inch drive and it’s capable of producing 1700 ft-lbs of torque, allowing you to handle the toughest fasteners like those on trucks, trailers, tractors and other farm machinery.

Equipped with Aircat’s patented vibrotherm drive pin-less/twin hammer clutch, the absence of a pin that takes the full impact of the hammer in the Aircat 1778-VXL makes it lasts longer than the competition due to the reduced wear and vibration.

The pin-less twin hammer clutch reduces the vibration of the tool by up to 40 percent and increases the lifespan by up to 50 percent. Thus, if you get one of these, you’ll find out that it works quieter compared to other pneumatic impact wrenches, and you’d definitely be using it for a longer time.

An inbuilt noise muffler also helps to reduce the noise helping to keep your hand and ears at ease as you work with the tool.

6. Porter Cable PCE211 Corded ½ Inch Impact Wrench

Porter Cable PCE211

Most mechanics and pros normally gear towards using battery powered impact wrenches due to their portability. They can easily be picked up and used anywhere inside the workshop and around the workshop as long as the battery is charged.

However, some folks still prefer the old ole corded model, one of which is the Porter Cable PCE211. This is a 7.5 Amp corded impact wrench capable of producing 450 Ft-lbs. of torque.

Now this is not as portable as a cordless model, but the advantage for someone using this is there’s no more downtime as result of battery running down. It’s just plug and play any time you want.

For cordless and air powered units, the torque produced reduces as air pressure drops or as the battery runs down. On the other hand, with a unit like this corded Porter Cable, it receives consistent electric current and power from an outlet and therefore produces consistent torque.

Producing 2,200 rpm of speed and 2700 BPM, the Porter Cable PCE211 is a very efficient power tool suitable for intense or very demanding jobs. It’s a workhorse that will not slow down like battery powered units as their battery runs down.

It comes equipped with a ½ inch hog ring anvil for easy and quick socket changes during use.

7. AVID Power Cordless 1/2 Inch Impact Wrench

AVID Power cordless impact wrench

Producing a maximum torque of 330 ft-lbs, the AVID power cordless impact wrench is not your ideal tool for loosening lug nut of tractors and those of bridges.

However, it will fit perfectly for the average car owner or small workshop owner for loosening wheels off cars, motorcycles, trucks, automotive repairs and construction such as scaffold dismantling.

It has a maximum speed of 2000 rpm, but it also features a variable speed trigger that allows the user to vary the speed between 0 and 2000 rpm to match the application.

Equipped with a 3.0 AH battery with a fast charger that charges it in less than 2 hours, the AVID power impact wrench kit comes with every accessory you need to increase your productivity on the job.

Other accessories include 4 pieces of ½ inch impact sockets and a tool bag to carry and stow the tool when not in use.

8. WORKPRO ½ Inch Cordless Impact Wrench

WORKPRO impact wrench

If you own a simple auto repair shop and you need a relatively inexpensive impact wrench to break off lug nuts off cars on a daily basis, this WORKPRO will work just fine.

It’s advertised as producing 320 ft-lbs of torque. However, it doesn’t really produce as much as that, but it will work well for most car maintenance issues you may have like some rusted suspension nuts, bolts, and wheel nuts.

Like I said, it’s a relatively inexpensive tool just below 100 bucks. So, you shouldn’t expect to knock off nuts holding bridges together with this. Don’t go into the tractor yard looking to break off some lug nuts. This might not be powerful enough. But for your car and SUVs, you’ve got a good chance.

It features a ½ inch chuck, which means sockets will be easier to come by, and it comes with a 20V 2.0 AH battery pack. Also included is a fast charger to energize the battery once it’s down.

The battery may be a 2.0 AH battery but it holds its own, allowing the user to get a lot of work done before running down, and sometimes with lots of battery juice still remaining.

Sharing is caring!
