For the electric category, we chose Porter Cable to go head-to-head with Dewalt. We highlighted the best features of each model so that you can decide better which will suit you best.
I. What Is An Impact Wrench
An impact wrench is a socket wrench power tool that distributes high torque output with very little exertion by the user. The tool is most commonly used for loosening lug nuts. They are, in fact, actually much more versatile, and can be used in any high-torque situation.
These tools will always get the job done, regardless of whether the fastener is too tightly in place or is too stripped and worn for a wrench to grip. Impact wrenches offer additional force and grip to assist with the completion of assembling and dissembling.
Impact wrenches are often used in repair, maintenance, and assembly work because they offer reactionless tightening and quick results. Their handheld usability and unmatched affordability also make them a great power tool for individual DIY projects.
While there are other tools that can do what an impact wrench does, these options are not as efficient or effective. Plus, impact wrenches can even unbolt rusted fasteners. The rotation motion of the motor can loosen fasteners that have been stripped and cannot be gripped by a hand held wrench. No other tool is effective at this task.
With high torque output and strong rotational motion, these tools are incredibly versatile and powerful. They are also available in all sizes and several styles, which makes them great for a wide variety of applications.
II. How Does an Impact Wrench Work?
An impact wrench works by storing energy inside a rotating mass. It then delivers this potential stored energy into a sudden kinetic burst to its output shaft. This is what makes it different from a drill that rotates continuously with a consistent torque or an impact driver that's many leagues below the impact wrench in terms of overall torque.
Aside from providing extra force to improve torque, this stored power and pressure is also capable of pushing the fastener being worked on forward as well as back. It can both tighten and loosen. It also has a hammer mechanism that is allowed to spin freely after impact delivery instead of staying locked.
- Power Source: The impact wrench's most common power source is compressed air. It also makes use of hydraulic power and electric power as well, like the drill. Compressed air allows the power tool to have the best power-to-weight ratio as well as a low-cost design. Almost always, a simple vane motor is used on the impact wrench, typically with 4-7 vanes on it. A cordless version that uses an electric motor and battery power rose in popularity among DIYers as well.
- How a Pneumatic Impact Wrench Works: This is considered the most professional-grade impact wrench because it's the variant that offers the most torque and the best power-to-weight ratio. It uses air from a compressor to store energy on its shaft and vane-utilizing motor instead of easily depleted electricity. This means you get a wrench that's lighter and easier on your hands without sacrificing the torque. You'll need an air compressor on hand though.
- How an Electrical Impact Wrench Works: Like drills, you can get an impact wrench in corded and cordless varieties. Both require plugging the socket into an electrical outlet but one of them stores that electrical energy into a battery, allowing you more leeway when working with your power tool. The torque provided by this wrench is more than enough for the average DIYer. It's something you can bring with you on the road since it doesn't need an air compressor.
- Lubrication Systems: In order to keep the moving parts to wear down quickly, various lubrication systems are also used. One of the most common lube systems used in impact wrenches is oiled air. The other systems involve the use of special oil passages that are routed to certain parts or areas of the power tool that require lubrication. The hammer assembly specifically makes use of a sealed oil system to keep it operating smoothly without friction or overheating.
III. Types of Impact Wrenches
There are three primary types of impact wrenches available on the market today, for both at-home and professional use. These three types are cordless, air, and electric. Each type provides its own strengths and weaknesses that may play well to your needs and budget.
It have become the most common type of impact wrench used for everyday jobs. Like many cordless power tools, this widespread acceptance derives from their exceptional convenience and portability. Everything you need to operate a cordless impact wrench is built into its frame, including its battery power source. In terms of power and performance, cordless impact wrenches tend to remain fairly consistent over their lifetime, providing enough RPMs and torque to accomplish many standard jobs.
It have a lot in common with their cordless cousins, especially in terms of performance. These models also tend to provide an industry-standard level of performance when it comes to completing most jobs. However, an electric impact wrench trades in the weighty battery for an electric cord plugged into an electric socket. While this makes most electric impact wrenches lighter by nature, it also decreases their mobility and portability, due to their corded nature.
Finally, it stand out from the pack for implementing a unique method for tightening lug nuts and bolts – using compressed air. They pack an exceptional punch of RPMs and torque while preserving a lightweight frame. Because of their intended use, air impact wrenches tend to be built to last for decades, if they are well cared for.
Because of their noteworthy power, many mechanics and construction companies make use of them. These lightweight power tools don’t put extra strain on these workers’ arms. In addition, air impact wrenches are very unlikely to burnout, thanks to the fact that they cool down as more compressed air is introduced into its system. Electric or cordless impact wrenches, on the other hand, heat up substantially if used continuously.
It come with some noteworthy drawbacks though. While the tool itself tends to be affordable, this comes as only a partial investment. To use these power tools, you will also need large air compression equipment, which can be costly to those who don’t regularly work with the tool – such as mechanics. In addition, this type of impact wrench tends to be non-portable, thanks to its attachment to a weighty air cylinder.
IV. A Buying Guide for Impact Wrenches
Before you go out and purchase the first impact wrench available on the shelf, you should take some time to evaluate the various details that may impact your purchase. Not all impact wrenches were built to fill the same needs or meet every budget, so it is in your best interest to compare and contrast the leading models to find the impact wrench that was made for you.
1. Intended Purpose
Before you buy, you should evaluate what you intend to use your new impact wrench for. In broad terms, consider the types of jobs the impact wrench can help expediate and enhance. Then, consider if these jobs will take place primarily in one location – such as an auto mechanic shop or a construction site. Some impact wrenches are better suited to these locations, as they trade off portability for extra power. Your decision in this category should help guide you towards one of the three main categories of impact wrench – cordless, air, and electric – based upon each’s respective strengths and weaknesses (detailed above).
Also, you should carefully consider the specifications of each model and how they meet your specific work needs. For instance, every impact wrench will provide different gauges of their overall ability, including RPM, IPM, torque, and voltage. In general, a higher numerical rating for any of these categories implies that a device is more capable at its primary function. For example, a 24V cordless model will be able to supply more power to loosen a rusty bolt than a similar 20V model.
If you’re in the market for an impact wrench, you’ve also probably heard that torque plays an important role in performance. It does, as torque measures a tool’s ability to rotate a desired object. If your goal is to loosen lug nuts or tighten bolts, then you’ll want as much torque as possible (while remaining within budget, of course).
Finally, you should select an impact wrench that fits your budget. Every power tool comes with an up-front cost that may or may not respect the full cost of operating the device. For example, a cordless impact wrench may be a bit more expensive up front, but this cost balances out with its inclusion of a battery. On the other hand, an air impact wrench by itself is cheaper, but is overall more expensive to operate due to its need for compressed air equipment.
No matter where your budget stands, there is an impact wrench that’s right for you. Read on to learn about the best impact wrenches 2019 has to offer.
