The power and durability of impact wrenches
are essential for professional, DIY, and commercial use. These tools make short work of bolts, nuts, and screws, and are a must-have for any repair shop or garage.
Choosing an impact wrench can be tricky, with a wide variety of options on the market. There are a number of factors to consider before making a purchase, including performance, weight and grip, and noise levels.
How to Choose a Power Source
First, decide whether you want an electric or pneumatic air-powered wrench. The latter is a better choice for many jobs, particularly when the job site has limited space or if you have access to an air compressor.
You will also need to consider the capacity of your air compressor. It is critical that the compressor delivers sufficient airflow to sustain continuous use of your impact wrench without interruptions. For example, if you have a 1/2-inch impact wrench that requires 7.5 CFM airflow, then a compressor with a tank capable of delivering 410 liters per minute will be ideal for you.
How to Choose a Power Supply
Generally, most air impact wrenches run on 18v power supply, which is ideal for extended periods of use. However, some models operate on 12v for lower-intensity jobs.
How to Choose a Torque Level
A wrench with a high maximum torque is ideal for working on heavy fasteners and can help loosen stubborn fixings. But there is no point in overdoing it, and you should always check the fastener size and application before buying a tool with a high torque rating.
How to Choose a Handle Grip
The handle grip on your air impact wrench should be comfortable, but it should also provide sufficient grip for the tool's operation. This helps prevent wrist sprains and other injuries that can be caused by the tool's hammer action. It can be difficult to find an impact wrench with a good grip, but it's important to find one that is well-designed and constructed with a rubberized or textured surface.
How to Choose a Compressor and Air Hose
It is crucial that the air hose used with your impact wrench is properly sized for optimal performance. The hose length should be at least 40 feet, and you should ensure that it is able to transport enough air. This will prevent the air from being blown out of your impact gun and into the environment.
How to Choose an Air Impact Wrench With Brushless Motor
If you're looking for a new air impact wrench, it's likely that your next purchase will be powered by an electronic brushless motor. These units are more energy efficient and require less maintenance than traditional impact wrenches.
