Let’s find out!

Understanding the Basics of an Impact Wrench

Before we go any further, let’s start from the basics. This includes understanding what an impact wrench is used for and how it works.

What is an Impact Wrench Used For?

If you’re a newbie, you may be asking, “What is an impact wrench used for?” 

Well, it’s simple. An impact wrench is a power tool that has an exceptionally high rotational torque. This makes it perfect for any job that involves tightening and loosening lug nuts, bolts, or even rusted fasteners. 

While impact wrenches are used in a wide range of industries, they’re more commonly used for automotive assembly, machine tool production, heavy equipment repair, and major construction tasks.

Let’s look at some practical examples of impact wrench use cases.

  • Professionals in auto body shops and car companies often use impact wrenches to remove tight lug nuts when changing car tires
  • Aerospace engineers can use an impact wrench for the assembly and maintenance of important aircraft components
  • DIY enthusiasts will find impact wrenches helpful for small tasks in the garage, such as engine repairs or suspension work
  • Impact wrenches can be used for home improvement tasks like fence installation, deck building, or furniture assembly
  • Impact wrenches can also be used when maintaining pipelines and drilling equipment by oil and gas professionals

How Does an Impact Wrench Work?

Looking at all the numerous ways in which an impact wrench can be used, we bet you’re wondering, “how does an impact wrench work?”

Again, it’s pretty simple.

Impact wrenches work the way they do because they’re equipped with a powerful high-torque motor. This motor produces a hammering mechanism, which enables it to deliver powerful, quick concussive blows.

As a result of the hammering mechanism, the motor delivers a strong twisting motion with high torque, usually in short bursts. This powerful motion is powerful enough to either loosen or tighten stubborn bolts and nuts, depending on the use case. 

Types of Impact Wrenches: Choosing the Right Tool

Like most power tools, impact wrenches come in different types. It is essential to know the difference between the types of impact wrenches, as this will help you make an informed decision. 

Air Impact Wrench vs. Electric Impact Wrench

As mentioned, an impact wrench uses a motor to produce the torque needed for tightening and loosening motions. Now, this motor can be powered by either air or electricity.

An impact wrench that uses an air-powered motor is called an air impact wrench, while one that uses electricity is called an electric impact wrench.

  • Air Impact Wrench: Also called a pneumatic impact wrench, an air impact wrench uses compressed air to generate torque. As such, it is equipped with an air compressor, which serves as its power source.

It is commonly used in automotive shops and industrial settings. It is also a popular choice because it doesn’t have an electric motor, making it lighter than the electric impact wrench.

The VEVOR air impact wrench is made from lightweight aluminum. So, although it is powerful enough to deliver up to 4950 foot-pounds high torque output, it still remains lightweight and easy to operate. 

  • Electric Impact Wrench: This type of impact wrench is powered by electricity, and so must be plugged into an electrical outlet to work. This makes it unsuitable for tasks that require a lot of mobility due to the length of the chord. 

It is also heavier than an air impact wrench due to the type of motor it uses. As such, it is more suitable for stationary projects in workshops where power can easily be accessed. 

Cordless vs. Corded Impact Wrenches

An impact wrench can also be cordless or corded.

  • Cordless Impact Wrench: As the name implies, a cordless impact wrench does not require a cord to operate. It typically runs on batteries, making it portable and perfect for situations where mobility is a priority. 
  • Corded Impact Wrench: On the other hand, an impact wrench can also be corded. This means it has to be plugged into an electrical outlet before it can function. It is better suited for stationary tasks that do not require a lot of mobility.

Key Factors to Consider When Choosing an Impact Wrench

Choosing an impact wrench is serious business. You must consider certain factors like power, weight, drive size, and durability if you want to make the right choice. Let’s discuss these factors in detail below. 

Power and Torque Output

An impact wrench is essentially useless without the right power and torque output. As such, power and torque are some of the most essential factors you must consider when choosing an impact wrench.

For automotive tasks, you’d usually need an impact wrench with a torque of about 100 to 500 foot-pounds. However, you will need a higher torque for more heavy-duty tasks.

If you use a wrench with insufficient torque, it can lead to loose bolts and nuts, which pose safety hazards. On the other hand, an impact wrench with excessive torque can over-tighten bolts and nuts, which can cause severe damage to machine parts.

To avoid this, always check the instructions of the impact wrench to check its minimum and maximum torque output. This will help you pick a tool that can adequately meet your needs. 

Weight and Ergonomics

The weight of an impact wrench plays a huge role in its usability. If it’s too heavy, you may find it difficult to carry about, which will affect the efficiency of your work. As such, you must look out for an impact wrench that is portable and lightweight yet still effective.

It is also important to pay attention to the design of the impact wrench. An impact wrench is a power tool that does most of the work for you. However, it must be designed in a way that makes it easy to hold onto, especially during long tasks. This will greatly enhance your user comfort and reduce strain and arm fatigue. 

Drive Size

An impact wrench is typically equipped with different drive sizes. The drive sizes could be 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, or 1 inch.

If you want to carry out tasks that require a high level of precision and accuracy, you’ll need smaller drive sizes, such as 1/4 and 3/8 inches. 

On the other hand, the 3/4 or 1-inch diameter impact wrenches are ideal for larger industrial tasks where precision may not necessarily be a priority. For example, they can be used for tightening and loosening bolts and nuts in large industrial tires.

The most common drive size is the 1/2-inch diameter wrench. It provides the perfect balance of precision and efficiency. You’ll often find them in use in regular-sized automotive repairs. 

Durability and Build Quality

Impact wrenches are often used in high torque operations, so they need to be of high build quality in order to remain durable.

The VEVOR air impact wrench does not disappoint in this aspect. In fact, it is made from high alloy steel, which provides a high level of resistance to extreme torque changes. It is also equipped with high-strength casings, which provide excellent durability. 

How to Use an Impact Wrench Safely and Effectively

Like most power tools, impact wrenches must be operated with care, or they can cause safety concerns. Let’s look at how to use an impact wrench safely and effectively. 

Step-by-Step Guide to Using an Impact Wrench

  • Gather Your Equipment: Ensure you have your impact wrench ready, along with the necessary impact sockets. Don’t forget to use personal protective gear like safety goggles and gloves.
  • Check the Air Pressure: Ensure you set the air pressure according to the manufacturer’s recommendations. Use the air regulator to adjust the air pressure accordingly.
  • Select the Appropriate Socket: The impact socket you choose should match the bolt or nut you’re working on to avoid accidents. Additionally, do not use regular sockets as they can crack under high torque. 
  • Put the Impact Wrench to Use: Once your safety gear is in place, you can then power up the impact wrench and put it to use. Position the wrench by placing the socket over the bolt or nut.

While holding the wrench with both hands, gently press the trigger to begin. Start slowly and gradually increase the pressure as you go. Use reverse mode to loosen a bolt and use forward mode to tighten it. Be careful not to overtighten bolts as this will cause problems. 

Maintenance Tips for Prolonging the Life of Your Impact Wrench

The key to elongating your impact wrench is maintaining it regularly. Here are some tips to keep in mind.

  • For optimal performance, regularly inspect your impact wrench for signs of wear and tear. Look out for cracks, rust, or loose parts and fix them early on, or they can cause issues down the line
  • Dust, dirt, and debris can pile up on your impact wrench and interfere with the effectiveness of its operations. To avoid this, wipe the wrench down regularly before and after each use. Avoid using harsh chemicals to clean. Instead, use a soft cloth and mild detergent
  • When the impact wrench is not in use, store it in a clean, dry place away from direct sunlight. Always ensure it is kept in a protective case or inside a toolbox
  • Sometimes, you may need to use lubricants to ease the operation of your impact wrench. When you do, always refer to the manufacturer’s manual for proper instructions
