If you’re a handy person who often works on your own car or maintains your home machinery yourself, you will most likely have a good air impact wrench in your toolbox. Here are the best impact wrench for home needs in 2021 review.
However, not all impact wrenches may be suitable for your home maintenance projects, and it is important to thoroughly assess your options to make sure you find the right one.
Keep reading to learn what an impact wrench is and the best one for your home maintenance needs.
What Is an Impact Wrench?
In short, an impact wrench is a power tool used for loosening or tightening various nuts and bolts. Impact wrenches have a hammering mechanism that provides strong, quick blows to bolts that would otherwise require extensive manual power to remove, making this tool suitable for even rusted or oversized bolts that are difficult to turn.
Impact wrenches are a common power tool in the automotive industry, but you can also use them for a variety of home maintenance tasks, including:
- Car repairs
- Removing wheels
- Maintaining heavy equipment
- Assembling products
There are also several different types of impact wrenches:
- Corded (Electric): A corded impact wrench is electric, and therefore needs to be plugged into a power socket for use. They contain an electric motor that drives the hammer units, transferring its motion to the output shaft. The main con is that corded impact wrenches are not very portable, and you may be limited when it comes to where you can use them.
- Cordless (Battery-powered): The main advantage of a cordless impact wrench is that it is highly portable, making it an easy tool to throw in the back of your trunk in case you ever need to perform a quick tire change. Unfortunately, the batteries in a cordless impact wrench can drain quickly, so that is something to keep ahead of.
- Pneumatic: A pneumatic impact wrench is compressed air-powered and commonly used in the automotive industry. It is relatively inexpensive and doesn’t heat up, thanks to the circulating air compressor. The downside to pneumatic impact wrenches is that they need an air compressor, which may take away from the portability and efficiency of the tool.
A ½-inch impact wrench is the best choice, as it is versatile enough for general use, and it is the minimum recommended size for automotive tasks.
