A screw that’s too loose or too tight will cause problems sooner or later. Enter impact wrenches.

These powered tools use a cool combination of torque and force to help you tighten loose screws and loosen extremely tight screws.

No need to break a sweat (or your tools) to ensure a screw or bolt is fixed properly. An impact wrench produces an amount of torque most of us usually can’t. It does so via a motor that powers a rotating mass.

If you’re looking for quality 1/2 & 1 inch impact wrenches, read on. I’ll cover the best wrenches and a helpful buying guide in this post.

Impact Wrenches Buyer’s Guide

As with any other tool, there’s a lot to consider when buying an impact wrench.

Each one has different variations, and what you choose solely comes down to personal requirements.

Here are some key factors you should consider before you pick up an impact wrench:

Power Source

Usually, an impact wrench would be powered by either of the three: compressed air, hydraulics, or electricity.

Impact wrenches using air pressure and electricity are more commonly used in the mechanical world.

While the hydraulic-powered impact wrenches are usually limited to industrial applications.

Okay, but which one should I get? Well, let’s take a closer look at these.

  • Compressed Air Impact Wrenches. These are usually connected to an air tank and use air pressure to create the force required for the job.

    You’ll usually find this kind of impact wrench at the mechanics since they’re more powerful than electric ones.

    Most of these are lightweight but require a full air tank to work. So they’re better suited for professional use.
  • Electric Impact Wrenches. Varying in size from a pistol to a drilling machine, electrical impact wrenches are far more convenient to handle. Although not quite as powerful as the compressed air type, they’re sufficient for many jobs.

    You can also choose between a corded and cordless impact wrenches.

If you’re a non-professional and looking to get an impact wrench for home use, I’d say go for an electrical one.

Torque

In case you slept through that physics class – torque is the twisting force that (in our context) acts on the screw or bolt to fasten or loosen it.

It’s the defining feature of any impact wrench and each of them has a defined maximum. You can use a torque chart, like the one below, to see which torque you need.

It’s important to make sure you use the right torque for your bolts. Make sure to match yours to this chart (or similar)

Some electrical impact wrenches let you choose between different torque settings to make them more versatile. Choose a range that’s more suitable for whatever you’ll use the wrench for.

Socket size

This one’s pretty self-explanatory. The socket size defines what size of nut or bolt you’d be able to use the impact wrench on. Usually, machines with a bigger socket size offer more torque and vice versa.

Voltage

Generally, impact wrenches with a higher voltage will be more powerful. Machines of 18-20 volts are more suitable for heavy-duty use. Smaller impact wrenches with a rating of 12 volts or less are better for smaller, remote, overhead work.

Corded vs Cordless Impact Wrenches

To keep things simple, I’m basically focusing on electrical impact wrenches in this post, which I assume you’re more interested in.

As I said, there are two kinds of electrical impact wrenches you can get; corded or cordless. Here are some main differences between the two:

Flexibility

Cordless impact wrenches offer you more mobility and flexibility. They also offer more freedom in terms of where or when you can use it as you’re not always eyeing a power source to plug it in.

Corded impact wrenches limit movement and might be a bit of a hassle to handle with the wire getting in the way.

Power

Most corded impact wrenches have a force of 250-300 ft/lbs which is adequate for lug nut use. However, if you need more power cordless impact wrenches are better for the job.

Price

Corded impact wrenches will cost anywhere between $50 and $100. While cordless ones can set you back $250-$400.

Now, let’s look at the best ½ and 1-inch impact wrenches I rounded up – these will last you decades.

Great Value Corded 1/2-Inch Impact Wrench

PORTER-CABLE Impact Wrench 1/2-Inch (PCE211)

It’s totally understandable if you don’t want to spend extra on a tool that you won’t use a lot.

You can get a corded impact wrench instead, for a fraction of the cordless price. And this one by PORTER-CABLE is one of the best corded ones on the market.

It only costs about $79.99 but comes with a 7.5 amp motor that can produce a torque of up to 450 ft/lbs. That rating may not be much but it should be sufficient enough for lug nuts, and for installing and removing other fasteners.

It produces a speed of up to 2200 RPM with an impact of 2700 BPM.

In terms of design, this impact gun has a drill-like look to it. It weighs around 8 lbs and is about 12-inches long. This might be heavy for some users but a powerful motor is a heavy motor.

It comes with a hog ring anvil for easy socket change and features a rocker switch for forward/reverse rotation.

The Porter-Cable PCE211 was first available in April 2017 and comes with a 3-year limited warranty.

Pros Cons

The biggest downside I believe is the weight and the bulky body which might make it difficult to work with in confined spaces.

But otherwise, in terms of torque and performance, this particular Porter-Cable Impact Wrench PCE211 delivers a winning combination of power and consistency.

AirCat Impact Wrench

Need a 1-inch impact wrench without breaking the bank? Get the AirCat 1992 1″ Truck Tire Impact. Priced at $303.18, this impact wrench promises great value and reliable performance.

Unlike other impact wrenches that depend on charged batteries and power outlets, the AirCat 1992 Truck Tire Impact is air-powered.

This means it derives its energy from compressed air to produce a torque of 1800 ft/lbs at a speed of 5000 RPM. It connects to a 1/2inch NPT air inlet that works best with a 220V compressor.

Since it’s air-powered, the wrench weighs about 26 labs. But it’s designed with an inner cavity of a D grip handle that you can adjust for both left or right-handed use by rotating it.

The wrench is designed as a hard-hitting pin-less hammer for greater impact. It also features an 8-inch extended anvil and a combined- friction ring and a through-hole anvil that enforces socket lock-on.

The wrench’s body is designed with triple-heat-treated Nickel chromium and Molybdenum alloy steel. This is powerful enough to withstand high pressures and last a long time. It’s reliable for heavy-duty tasks that electric-powered impact wrenches fail at.

This AirCat 1992 1″ Truck Tire Impact was first launched in August 2017. It comes with a 2-year warranty.

Pros Cons
AffordableMight be a bit too heavy for some
Good quality constructionAdded hassle of connecting to an appropriate air tank
Can withstand heavy-duty use
Lightweight compared to other 1-inch air-powered impact wrenches
Great impact

Our Verdict

If you’re on a budget and can’t compromise on power, this AirCat impact wrench will make you happy. It delivers high-impact torque that’s unmatched by its electric competitors and it’s made to withstand the massive power for decades.

The downside is, it’s bulky and you need a full compressor tank to fuel it. But if you see yourself using it quite often, it just might be worth the hassle.

Plus this model is designed to enhance comfort with its D-grip and extended anvil. So if you’re looking for an air-fueled impact wrench, it doesn’t get better than this.
