Best Impact Wrench: Buying Guide and Top 5

You know the frustration of trying to remove nuts and bolts that just won’t seem to budge. There is one tool that can make the job easier – an impact wrench. If you’re not well-informed about the ins and outs of this handy tool, you could end up with an impact wrench that is more trouble than it’s worth. Before you can pick one by its features, you need to know more about how they work and the different types that you can buy.

How Do Impact Wrenches Work?

In essence, it’s all about creating a lot of torque. Inside every impact wrench, there is a motor and a hammer-shaped mass. Once the impact wrench draws power, the hammer spins at a rapid rate, which gives the motor energy. As the motor’s energy builds and the hammer rotates, the motor drives the hammer into the tool’s anvil. As a result, you feel little impact, and you get more torque than you can produce on your own.

When Would an Impact Wrench Be Helpful?

Besides the enormous amount of torque, there is another benefit that comes from using an impact wrench – precision. This makes impact wrenches a must-have for auto mechanic shops and car enthusiasts alike. Impact wrenches are also commonly used for heavy-duty industrial applications and small at-home jobs. During times when you’re dealing with a rusted or stubborn bolt, an impact wrench becomes a lifesaver.

How Do Impact Wrenches Differ From Torque Wrenches and Impact Drivers?

Impact wrenches, torque wrenches, and impact drivers may be closely related in some ways, but their purposes are much different. While not an everyday tool, impact wrenches are great for removing bolts, nuts, and other fasteners. On the other hand, impact drivers are suitable for driving screws and other drilling activities. Finally, torque wrenches are well-adept at making exact adjustments.

What Type of Impact Wrench Should I Buy?

These tools are categorized by the way they’re powered. Corded impact wrenches are relatively lightweight. However, staying mindful of their power cord can become burdensome. On the other hand, cordless impact wrenches offer total portability because they operate on battery power. However, the battery adds a little more weight, and you have to keep it charged.

Hydraulic impact wrenches are another variety. These tools give the most torque, but they are only used on industrial jobs and construction sites. The second most powerful impact wrench is the pneumatic one. Pneumatic impact wrenches don’t weigh as much as corded or cordless ones, but you must keep it attached to an air compressor.

Which Style Is Better – The Inline Style or Pistol Style?

Impact wrenches can further be categorized by the way they look. Pistol-style impact wrenches look similar to electric drills. Due to their ergonomic design, pistol wrenches are more comfortable to hold, and they cause less hand strain during long working periods.

The other style is called an inline impact wrench. These wrenches are slim, and the anvil is either aligned with the wrench’s body or crooked at a right angle. If you need to reach in tight spaces, inline impact wrenches are well-suited for those tasks.

Regardless of your level of fix-it know-how, automatic tools make life easier. When you have a long to-do list, you don’t want an inefficient power tool slowing you down. No two impact wrenches are alike, so you can’t just get the first one you see. Before you purchase one, you need to know what set of features make an impact wrench a worthwhile buy.

Impact Wrench Torque
In the world of impact wrenches, torque takes the top spot as far as features are concerned, and there is no torque that’s considered too high. Therefore, you should pass on any impact wrench with a torque under 500 foot-pounds. Besides the maximum force behind the turn, make sure there is a control that lets you regulate the power for those precision tasks.

Impact Wrench RPM
The number of rotations per minutes is just as important as the torque. The more rotations an impact wrench can make, the less effort you have to put forth. When you are fastening, a fast RPM equates to getting the job done quickly.

Impact Wrench IPM
IPM, or impacts per minute, is a measurement of an impact wrench’s hammering action. Like the torque and the revolutions per minute, the higher the IPM, the better. An impact hammer with a rapid IPM will make more contact with the target.

Impact Wrench Anvil
The anvil size differs from one impact wrench to the next, spanning from one-fourth an inch to three-fourths an inch. There are also anvils as large as 2 inches, but the big ones are used for industrial applications. You also have to look at the type of anvil. A detent pin holds the socket tighter, but it takes longer to swap sockets. There is also a hog ring, which is great to have if you frequently change sockets.

Impact Wrench Motor
As with every tool, there is always a debate between brushed and brushless motors. Brushed motors are generally cheaper, driving down the cost of an impact wrench. However, brushless motors don’t have moving parts that cause the friction that leads to breakdowns.

Impact Wrench Battery
The type of battery in a cordless impact wrench determines the stability of the tool’s performance from start to finish. Usually, the battery will be nickel-cadmium or lithium-ion. Nickel-cadmium batteries are less expensive, but they cause the impact wrench’s motor to slow down when the battery gets low. This is not the case with lithium-ion batteries. Plus, lithium-ion batteries can hold a charge for a longer period of time.

Impact Wrench Ergonomics
Comfort counts. You want an impact wrench that is easy to hold. Therefore, the grip should be contoured, rubberized or textured. Don’t make the mistake of picking a heavy impact wrench, thinking it will be more powerful. The key to reducing wrist strain during long projects is using a lightweight impact wrench. Additionally, a lightweight impact wrench is easier to carry around a job site.

Impact Wrench Durability
Obviously, an unreliable impact wrench does you no good. As mentioned earlier, ones with a brushless motor are less likely to break. However, the material out of which they are constructed also matters. Durable impact wrenches are made of steel or other metal, not plastic. They may even have a titanium housing and metal transmissions.
