Impact Drivers Buyer’s Guide

Many people tend to confuse the impact driver with a hammer drill. Like a regular drill, a hammer drill is distinct from an impact driver and designed for a different purpose. A hammer drill is like a regular drill with the added ability to vibrate bits forward and backward rapidly as it spins. This makes the tools much faster and easier to drill blocks, stone, brick, or concrete.

If you need to drill holes and drive small screws, then a standard drill can get the job done. But if you’ve got some serious jobs around the house to handle, such as building a deck or treehouse, or you have a plywood subfloor to install, consider investing in an impact driver.

Designed for Speed and Power

These tools are designed to cut your work time in half, giving you the satisfaction of driving huge screws into wood in a matter of a few seconds. Like any type of power tool, if you invest in an impact driver, make sure you know how to use it safely. Wear hearing protection and safety glasses and keep your hair, clothes, and hands clear of the tool when it’s in operation.

The impact driver will quickly become your go-to tool for a variety of jobs around the home or at work. The best impact driver is powerful, durable, and can help you finish a project faster, compared to a cordless drill or driver. Before I go over the different features available, first, let’s learn more about some of the benefits impact drivers have to offer and what makes these tools so versatile and powerful.

Cordless Impact Driver Benefits

carpenter using an impact driver

Impact drivers are powerful, versatile, and packing the type of power you need to handle bigger jobs around the home, in the workshop, or on the job. Below, you’ll find a list of some of the impact driver’s most important benefits.


An impact driver has an impressive advantage over standard drivers and drills and that advantage is the massive amount of torque. Essentially, this high level of torque means with an impact driver you’re able to bore large holes or drive a big screw with a small driver.


The best impact driver can handle jobs of all sizes. When used with a small bit they work just like a drill, however, they offer nearly twice the RPM’s compared to most cordless drills. When used with a bigger bit, an impact driver will move into high torque impact mode, allowing the user to bore big holes with a small driver.

One-Handed Use

When you use a standard driver, you need to put all of your weight behind the tool and use plenty of force. If you don’t, a bit can easily cam out, chewing up the screw head. You won’t run into this issue with an impact driver. On the driver, you’ll find a hammer mechanism that’s responsible for producing torque and also creates forward pressure. This means you won’t have to use so much physical force to prevent a cam out. This tool is perfect for one-handed use and stretch and drive situations.

Additionally, these drivers are so versatile that they can take on pretty much any job. However, when high torque isn’t necessary, most pros like to avoid the noise and will opt for using a standard drill instead.


Typically, a high amount of torque will put extreme strain on the user’s arm. Fortunately, because the impact driver generates less wrist twist compared to a standard driver you will not experience the same type of wrist strain and soreness after a job

Other Important Features

Below, I’ve included a list of the different features available. These features can have an impact on the impact driver’s performance, power, and overall quality.

Amp Hours (AH)

Amp-hours is another feature that you’ll want to keep in mind and one that can indicate how long you can use the driver. Amp-hours is the number of amps a battery can discharge for one hour.

How often or how long you’ll use your impact driver is determined by how long the battery is going to last before you have to replace it or recharge it.

Brushless and Brushed Motors

With a brushed motor there are carbon brushes that pass their power to the armature. This will energize the copper wire coil, causing a chain reaction that will cause it to spin between the stationary magnets.

Efficient Power

A brushless motor contains coil and wire magnets that are reversed, which is designed to ensure that contact with the armature comes from the bearings that it spins on. Because of this design, a brushless motor is considered more efficient and durable than brushed motors which is why it’s also the most expensive option.


These days, the best impact drivers come equipped with some type of ergonomic handle or grip that’s designed to promote user comfort and prevent hand and wrist strain.

Ergonomic Design

However, not all handles are created equal. When you’re shopping for an impact driver make sure that the one you choose comes equipped with plenty of grip so you can reduce the chance of accidentally dropping it or the grip slipping out of your hands when your hands become sweaty.


Because of the size of the motor and the type of  power the best impact drivers are packing, some models can be quite heavy. However, some manufacturers do create more compact and lightweight impact drivers. If possible, look for a lighter model. A lighter tool will help prevent wrist strain and can reduce user fatigue.

Battery Power

Modern models are battery powered and their batteries are usually available in three sizes:

  • 12-volt
  • 18-volt
  • 20-volt

Higher voltage means more torque and power, which is a good thing if you want to drive screws much faster. However, you should keep in mind that a higher voltage also means heavier, larger batteries, and a power tool that’s more difficult to slip in and out of your tool belt.

The 18v impact driver is the most common and features the right amount of power and torque needed to handle most jobs, big and small. A 20-volt impact driver, compared to an 18-volt model, offers faster speeds and more torque and is commonly used to handle industrial materials. A 20-volt model may be overkill for smaller home projects. A 12-volt impact driver is perfect for smaller jobs, but cannot handle drilling through tougher materials.

Driver Bits

driver bits

A drive bit is what is used to turn a screw via torque. Driver bits comes in a variety of configurations designed to fit a range of screws available. Whatever screw you’re looking for, there’s a driver bit that will fit it. Driver bits, also referred to as driving screws,  have a hex shank head that will allow them to fit in the impact driver’s collet. Some impact driver kits will come with a few bits, while other drivers will not come with any. In most cases, you’ll have to purchase the bits you need separately.

Inch Pounds of Torque

Impact drivers that have 1500 to 1800 inch-pounds of torque will have a higher RPM rating. The tool will do work more quickly than an impact driver that has slower speeds and more torque.

 Frequently Asked Questions

What is the Best Size Impact Driver?

Many pros recommend the half-inch impact driver, which is more versatile and can be used for a wide range of projects, whether you’re working on your car or on a construction site. For home use or smaller jobs in general, go with either the 3/8 impact driver or the ½ inch option.

Can I Use an Impact Driver for Screws?

An impact driver operates much like a cordless drill, meaning it uses rotational force to drive screws. This tool also uses its bursts for fast power if it feels any type of resistance. You can use an impact driver for long screws as well as large fasteners.

Is an Impact Driver the Same as a Screwdriver?

Yes and no. The impact driver is designed for denser, heavier materials and more prolonged use. The impact driver uses the type of force that’s similar to a hammer tool, which is what helps the tool drive screws quickly into dense materials.

Final Thoughts

The impact driver is one of the most useful power tools that will come in handy for a variety of  DIY projects, when you’re in the garage working on the car, doing some construction around the home, or for professional use on the job site. This guide and my reviews of the best-selling impact drivers are designed to help you choose the right model, one that’s packing the type of power you need to get the job done.
