What kind of power tool do you need for your project? If you’re looking for something that can deliver a lot of torque, you might want to consider an impact wrench. Impact wrenches come in different sizes and styles, so it’s important to know which one is suitable according to your requirements.
Here, we will deliberate about the different types of impact wrenches according to their power source and size; and also discuss their uses. An impact wrench is more valuable to you if you’re an experienced contractor or just someone who enjoys DIY around the house. Read on to learn more about impact wrenches!
Different types of impact wrenches – according to their power source
According to their power source, impact wrench are three types-
- Electric-powered or corded
- Compressed powered or air (pneumatic)
- Battery-powered or Cordless
Corded impact wrench
A corded impact wrench is a more powerful tool that can loosen or tighten enormous stubborn bolts and nuts. It uses a rotating mass to create torque and an anvil to store energy. When this energy is released, it makes a sudden impact that can loosen even the most tenacious bolts.
Corded impact wrenches are generally suitable for those who work in industrial and automotive settings, where they can be used to remove fast or install heavy parts.
While power is the most crucial consideration, and don’t worry about portability, a corded model is ideal for you because it gives you more power with a longer run time.
However, they can also be used for smaller projects around the house, such as assembling furniture. A corded impact wrench may be the right choice if you need a powerful tool to assist with a challenging project.
Cordless impact wrench
A cordless impact wrench is a power tool that is powered by a battery, and the user squeezes a trigger to activate the torque. The impact wrench is designed to break the lug nuts loose without damaging the wheel or the studs. The cordless feature makes it more portable and compact, which is perfect for outdoor work. It is also ideal for tight spaces that a corded model would not be able to reach.
When altering a tire, using the accurate size socket is essential for the lug nuts. Different types and sizes of impact wrenches are available in the market and are typically marked with the highest torque they can handle.
For example, 1 inch and 1/2-inch 20V cordless impact wrench can handle around 2000 ft-lbs and 1000 ft-lbs fastening torque.
Using an impact wrench that is too powerful for the job can damage the wheel or the studs. Therefore, selecting the right-sized impact wrench for the job is important.
Air impact wrench
Air or pneumatic impact wrench is a power tool that delivers high torque to loosen or tighten fasteners. They are popular in heavy-duty applications such as automotive and construction, where there is a need to remove or tighten large bolts quickly. Air impact wrenches use compressed air to generate high levels of torque, making them very powerful tools.
As a result, they can be used for a wide range of fastening and loosening tasks. However, impact wrenches can also be dangerous if used improperly. For example, if the operator does not have enough knowledge and a firm grip on the tool, it can easily wrench out of their hands.
In addition, an impact wrench’s high torque levels can damage sensitive components. Consequently, it is essential to use an air impact wrench only when needed and obey all safety instructions when using this tool.
If power is the most important thing when choosing an impact wrench. In that case, an air impact wrench can be the better choice because a 1/2 inch can generate 1000 to 1500 fastening torque that can easily handle any stubborn fasteners.
Different types of impact wrenches – according to their size
When it comes to the size of an impact wrench, they are four types-
- 1-inch impact wrench
- 1/2 inch impact wrench
- 1/4 inch impact wrench
- 3/4 inch impact wrench
- 3/8 inch impact wrench
1-inch impact wrench
A 1-inch impact wrench is equipped with a 1-inch square drive that can be attached to various sockets of different sizes. It is designed for use with impact-rated sockets made from a more rigid material that can withstand the maximum torque output of the wrench.
The 1-inch impact wrench is often used in automotive applications, such as changing tires or brake repairs. The 1-inch wrench can also be used in industrial and construction settings. Selecting a model that offers the right amount of power for the application is important.
Too much power can strip threads or damage fasteners, while too little power can result in an ineffective tool. A standard powerful 1-inch impact wrench offers you 1200 ft-lbs to 1500 ft-lbs max torque with 5000 to 6000 RPM speed.
3/4-inch impact wrench
A 3/4-inch impact wrench is a powerful tool that is often used in automotive and construction applications where regular hand wrenches will not suffice. While they are compelling, they can also be dangerous if misused.
Impact wrenches come in various sizes, and the size you need will depend on the application you are using them for. For example, a 3/4-inch impact wrench is typically too large for most home projects.
However, it may be a perfect size if you are working on a car or other heavy machinery. When shopping for an impact wrench, consider the size and power you need for your project.
1/2 inch impact wrench
A 1/2-inch impact wrench is a tool that delivers a high amount of torque, but not more than 1 and 3/4 inches—making it ideal for heavy applications. The wrench uses a hammering action to generate the necessary force, and the resulting impacts can be pretty powerful.
So, it is crucial to use caution when operating a 1/2-inch impact wrench and always follow the manufacturer’s instructions. In general, these wrenches should only be used when other tools are not up to the task, as they can easily cause damage to delicate materials. When used correctly, a 1/2-inch impact wrench can be valuable to any toolkit.
The most popular M18 2767-20 FUEL 20V 1/2 inch impact wrench can provide fastening and nut-busting torque 1000 ft-lbs and 1400 ft-lbs.
3/8-inch impact wrench
A 3/8-inch impact wrench can deliver 200 ft-lbs to 300 ft-lbs max torque, and it’s suitable for working on small projects that require less than 300 ft-lbs. But a 3/8 air impact wrench is equipped with a socket that fits over the bolt head, and the twist itself is attached to an air compressor. When the trigger is pulled, the air compressor creates a powerful impact that loosens the bolt.
You can use A 3/8-inch impact wrench in small applications, where they are used to loosen bolts on scaffolding or other equipment. In general, impact wrenches are best suited for stubborn bolts that cannot be removed by hand.
1/4-inch impact wrench
A 1/4-inch impact wrench uses a hammering action to generate high torque levels, making removing stubborn fasteners much easier. Impact wrenches are available in various sizes, but the most common is the 1/4-inch impact wrench.
This small size is well-suited for most household tasks, such as assembling furniture. However, it is important to note that impact wrenches are very powerful, so it is vital to use them with care; otherwise, they can cause severe injuries.
When using an impact wrench, always start with the lowest setting and gradually increase the torque level until the fastener is loose.
In addition, be sure to keep your body clear of the Rotating parts to avoid injuries. With a bit of practice, you’ll loosen and tighten nuts and bolts like a pro in no time.

Are all impact wrenches the same?
Impact wrenches are available in various sizes and styles; each type has benefits and drawbacks. For example, air-powered impact wrenches are typically the most powerful option, but they require an air compressor, which can be bulky and expensive.
Electric impact wrenches are more portable but may not have as much torque as air-powered models. Cordless impact wrenches are the most convenient option, but they may need to be recharged frequently.
When choosing an impact wrench, it is crucial to consider the project’s specific needs. For most home projects, a cordless model will suffice. However, an air-powered or electric model may be a better option for larger projects or those who plan on using the wrench frequently.
