What to Consider When Choosing the Best Cordless Impact Wrench

The impact wrench that’s best for you depends largely on what you’ll be using it for. Keep the following features in mind when determining which impact wrench is the most suited to your needs.

Brushed vs. Brushless Motor

Without getting lost in the complexities of power tool engine mechanics, it’s enough to say that brushless motors don’t have as many moving parts as brushed motors. Moving parts create friction, and friction causes a loss of efficiency. Consequently, a cordless impact wrench with a brushless motor has several advantages over one with a brushed motor. This includes a greater power-to-weight ratio, higher engine speeds, a longer life span, and less maintenance.

But all these advantages come at a cost. Because of their superior features and more advanced technology, cordless impact wrenches with brushless motors can be considerably more expensive. However, considering that brushless engines tend to last longer and require less maintenance, the extra cost might well be worth it.

RPM, Torque, and IPM

Torque, RPM, and IPM are the three key factors that determine an impact wrench’s power. Of these three, buyers should pay the most attention to the torque value. Simply put, torque is the amount of twisting power an impact wrench has, so an impact wrench with higher torque will have more overall power and generally perform better.

RPM and IPM are also important values to keep in mind. RPM stands for “revolutions per minute” and represents how fast an impact wrench can drive your fasteners. IPM stands for “impacts per minute” and refers to the number of impacts from the “hammer” (the internal mechanism that puts the “impact” into an impact wrench) generated per minute. A higher IPM value will make the wrench work harder as the resistance increases.

Batteries and Run Time

Cordless impact wrenches receive their power from rechargeable batteries. Consequently, the battery’s power (measured in volts) will greatly influence the overall power (measured in torque, RPM, and IPM) the cordless impact wrench can possess.

Cordless impact wrenches most often have 18-volt batteries, but there are some exceptions. Impact wrenches with greater amounts of torque can have batteries as large as 20 volts, while less powerful and more compact impact wrenches can have batteries as small as 12 volts.

Although the volt rating of a battery determines the tool’s power, it doesn’t say anything about how much run time the battery has. That’s determined by a battery’s amp-hour (“Ah”) rating. For example, an 18-volt, 3-Ah battery will run about twice as long as an 18-volt battery with a 1.5-Ah rating. When you put the volt and amp-hour rating together, you’ll be able to roughly gauge how much power and endurance a given impact wrench will have.

Drive Size

Every socket is composed of two primary parts: the drive socket and socket head. The socket head is the female part into which a nut and bolt fit, while the drive socket is the female component that’s attached to the wrench. A cordless impact wrench’s drive size is based on the size of its anvil, or male input shaft that the socket fits into. In other words, an impact wrench’s drive size dictates the size of the sockets it can use.

Cordless impact wrenches are available in sizes from 1/4 inch to 1 inch, with each size having its set of advantages and disadvantages. As a general rule, the larger the impact wrench’s drive size, the more powerful the impact wrench. On the other hand, a wrench with a larger drive size will be larger and bulkier and will be more difficult to fit into tight spaces. For general purpose use, an impact wrench with a 1/2-inch drive size will be the most versatile since it’s both moderately powerful and compact—allowing it to accomplish the widest variety of tasks.

Sound and Vibration

You might think that an impact wrench with more power is automatically better in every way than one with less power, right? Not so fast. As with so many other things in life, there’s a trade-off. When it comes to a cordless impact wrench’s power, that trade-off is in the form of increased sound and vibration. Although battery-powered impact wrenches don’t generate as much sound and vibration as their pneumatic counterparts, both forms of impact wrenches are known for causing hand and ear fatigue. If you’re exposed to either for too long, the sound and vibration can lead to damage to these areas.

Thankfully, many cordless impact wrenches incorporate vibration-reducing ergonomic handles to buffer the impact of excessive vibrations on your hands. Many also allow for adjustable torque levels so you can limit your exposure to the loud and physically jarring high-torque setting to times when you really need it. But no matter what noise and vibration reduction features your impact might have, you should always wear hearing protection and take regular breaks when operating it.


Cordless impact wrenches have two basic grip styles: pistol grip and in-line grip. As the name implies, pistol-grip handles resemble the handle and trigger assembly of a standard pistol. This is the handle type that most power drills and impact drivers have and also is the most commonly found on impact wrenches. Pistol-grip handles are the most popular because they’re comfortable to hold and create less hand fatigue during long work periods.

Impact wrenches with in-line handles are long and slim, somewhat resembling a regular screwdriver. With in-line impact wrenches, the anvil aligns with the body of the impact wrench, and the handle and trigger are integrated into the back side of the wrench. This variety is best for maneuvering in the tight and compact spaces where a pistol-grip impact wrench can’t fit. However, there are compact versions of traditional pistol-grip impact wrenches that serve this purpose as well.

Safety Tips for Using a Cordless Impact Wrench

All power tools should be used with caution—and cordless impact wrenches are no exception. The first step of using an impact wrench safely is to read the user’s manual for instructions on proper use and recommended safety considerations. Be sure to select the recommended torque setting for the sockets you’re using, and don’t force the tool to operate beyond its stated performance specifications.

You should also avoid using your impact wrench for complex tasks that far exceed your current skill level since that greatly increases the chance of an accident. Make sure you’re equipped with all the necessary safety accessories (like hearing protection, safety goggles, and gloves), and take frequent breaks to avoid fatigue. Using your impact wrench for only its intended purpose with the proper safety equipment will go a long way toward keeping you safe, but here are a few more tips:

  • Inspect the impact wrench for damage before you use it, and if you discover any defects, either fix or replace it.
  • Make sure the sockets you’re using are rated for use with an impact wrench since if they’re not, they can break and cause injuries.
  • Don’t use your impact wrench in wet conditions since electrical shock can result.
  • Dress appropriately, avoiding baggy clothes, loose jewelry, and free-flowing long hair.
