Best Impact Driver Head to Head Review 2020

30+ Models Go Head to Head to See Who Can Earn the Title of Best Impact Driver

After looking at the impact drivers currently available, we brought in more than 30 models to find out who makes the best impact driver in multiple classes. There are some impressive new players entering the scene that look to challenge our traditional categories. When it was all said and done, the biggest names still stepped up to the plate.


Best Impact Driver Overall

Makita 18V LXT Brushless Impact Driver XDT16

Before we ever started crunching the data from our test results, Tom Gaige called me up. He wanted to tell me how impressed he was with the Makita XDT16 impact driver. It’s the most compact (by 1 mm) and the second lightest on our scales. At the same time, it held its speed. It also produced more measurable torque than impact drivers touting hundreds of more inch-pounds in their specs.

Makita XDT16

Makita continues to blaze its own trail with its control system. 4 standard modes take care of the basics. From there, 2 Tech modes help with metal fastening, Assist mode gives you a slow start for wood fastening, and Auto-Stop mode loosens a bolt and stops so you can thread it off by hand. You can even program the button above the trigger to set your favorite mode or just let it run through the 4 standard ones.

Best 12V Impact Driver

Milwaukee M12 Fuel Surge

In our 12V testing, it took another M12 Fuel product to finally knock the M12 Fuel 2553 off the top of our charts. The Milwaukee M12 Fuel Surge did it with higher torque numbers in our tests and significantly less noise than any other impact driver we’ve tested. Want a head-to-head between just the M12 Fuel impact and the Surge? Check it out here!

One of the features that stands out on the Milwaukee 2553 is the self-tapping screw mode. It’s something we see in the 18V models, but it’s not so common in the 12V class. When you kick into it, you start the drive quickly and automatically back down in power to avoid shearing off screw heads in metal fastening.

Best Oil Pulse Impact Driver

Makita 18V LXT Oil Pulse Driver XST01

The oil pulse driver class is interesting thanks to the range of styles available between just 4 brands. The Makita XST01 oil pulse driver rises ahead of the competition by keeping its weight in check and maintaining its speed under load. And of course, it’s quieter than any standard 18V impact driver. Its only major hiccup is in value since it’s only available as a bare tool—something that won’t be an issue if you’re already on Makita’s 18V LXT battery platform.

Best Impact Driver for DIYers

Craftsman V20 Brushless Impact Driver CMCF820

Craftsman V20 Brushless Impact Driver - Best DIY Impact Driver

Even though Craftsman didn’t dominate the DIY category across the board, it prioritizes a combination of speed, power, size, and design that gave it a comfortable win over Ryobi in second place. The final score for the Craftsman V20 brushless impact driver easily put it in the top 10 against professional models as well.

Wait, Something’s Different

If you’re a fan of Pro Tool Reviews, you’ll notice that this is a different format for our shootouts. Rather than looking for the best impact driver in one class, we decided to make it more comprehensive. We took a hard look at the most current models available and really dialed in the testing to make it as objective as possible. In addition to this article, you’ll find breakouts for each class and individual reviews for every model.

How We Tested

Speed Testing Under Load

No-load speed is great, but maintaining speed under load is more important. To test this, we glue up layers of OSB subfloor. We use OSB because it delivers more consistent results than other lumber.

Using 5/16-inch Milwaukee Shockwave nut drivers, we drive 3-5/8″ long, 1/4″ diameter ledger screws. These have threads roughly halfway down and we measure the maximum RPM with all of the threads engaged in the final inch of driving.

The higher the RPMs, the faster the impact driver drives the fastener under a moderate load.

If an impact driver can’t drive the ledger screw completely, we measure how much of the screw sits above the OSB after a 30-second drive.

The value we report is the average of 5 tests with outliers in the data rejected and/or retested.


Before testing speed with ledger screws, we measured the true no-load speed of each impact driver with the battery kitted or recommended for each one. We take the ratio of those measurements to give us a percentage of no-load speed while driving.

The result tells us how hard the motor is working compared to the other impact drivers in the same class. Even though a model might be slower, if it’s working more efficiently, there’s less strain on the motor, giving it a shot at a longer life.

Torque Testing

We run two tests using a steel I-beam with Grade 8 hardened bolts, washers, and nuts. The bolts are welded to the I-beam, so they won’t move. We use Milwaukee Shockwave 1/2” square drive adapters and an impact-rated socket on the tool.

The first test starts by hand threading each nut down and using the impact driver to give it three 3-second bursts. This tightens it as much as possible without overloading the motor.

Some impact drivers have a soft start, and the hydraulic impact drivers don’t hit as hard in general. Because of this, we also ran the test with a 5-second burst. It shows us which ones need longer to ramp up to a higher hard torque value and which ones hit hard out of the gate. The number we report is the higher of the two.

Measuring Soft Torque

To get a value, we use a Gearwrench 85079 digital torque wrench ($147) to measure how much torque it takes to loosen the nut back off. It only takes about 80% of the fastening torque to remove a bolt. So while our test is a consistent way to measure, it’s not a direct fastening torque measurement.

It is possible to get higher torque values with longer engagement. However, most applications that need more are better suited for stronger impact wrenches, so that’s where we draw the line.

Raising Our Torque Limits

In the second test, we use our torque wrench to tighten each nut to a specific level. Then, we see if the impact driver can break it loose. Some impact drivers can break more than the torque wrench’s 250 ft-lb limit, so we use the Gearwrench 64-832G torque multiplier to set the torque we need.

We work up or down in 10 ft-lb (120 in-lb) increments until we find the maximum it can loosen. This test separates the impact drivers into 10 ft-lb nut-busting classes up to 250 ft-lbs.

Once a driver exceeds 250 ft-lbs, the 6:1 torque multiplier changes the confidence in our accuracy. For models that need the torque multiplier, we move to 25 ft-lb increments.

One thing to keep in mind is that the results represent the minimum torque each one can break and the actual value is between it and the next highest interval.

The Problem with Testing Torque on an Impact Driver

Smarter people than us have tried to come up with standard torque testing for impact tools, but it proves to be a nearly impossible task because of how the impacting action works.

Nut-busting torque is roughly 50% more than fastening torque. However, it’s not exactly the same in every tool, so there’s no formula we can use to tell you how much fastening torque each model actually has. It does let us differentiate between what each impact driver can fasten to and break away, however.

There’s no magic in reverse torque. It simply takes less effort to loosen a nut than to fasten it to the same point. While an impact driver might fasten to 150 ft-lbs, it can loosen 225 with the same amount of actual torque.

Our results don’t mirror that ratio perfectly, and other factors outside of our control affect our ability to try and confirm manufacturer specifications. However, our tests do allow us to repeatably and reliably differentiate between each impact driver.

Noise Level

Even the best impact driver is a loud tool. The speed and frequency of the anvil striking against the hammer generate a lot of noise.

Hydraulic impact drivers use an oil-based system with an elliptical mechanism to reduce the amount of noise greatly. They hit with less violence and engage the anvil longer than a standard impact driver.

We use an SPL meter at 24″ (the average distance from tool to ear) to measure the A-weighted decibels that each impact driver produces.

We ran tests inside and then outside in an open field with no difference in measured noise level. Moving into a small bathroom, there’s a significant increase in decibels. With those results in mind, we do our testing in the shop.


Since impact drivers are designed to be powerful, but compact tools, the overall weight is an important factor. Keeping it lower helps reduce the amount of fatigue you have to deal with over the course of a workday.

To keep the weights down, we asked each manufacturer to send a compact battery with their tool. In most cases, you can cycle two batteries between the tool and the charger without stopping to wait for a battery to finish charging.

What complicates matters somewhat are the upgraded batteries on the market. The shift from 18650 cells to 20700 and 21700 means tools have more power and capacity available. There are also brands that go with a 6-cell system instead of the 5-cell systems that make up 18V/20V Max packs.

Here are the packs that break the mold:

We measure the bare weight of each tool and again with the most advanced compact battery available at the time of testing.


The best impact driver models in each class will have a compact footprint. We measure the height and head length of each impact driver with a digital caliper to see which manufacturers focus on keeping the size down.

Makita XDT16

The length is arguably more important than the height. Tools with a more compact head can squeeze into a smaller space.


While we don’t come across many tools that have a terrible grip, some are better than others. Slide packs are important because they give design teams more freedom in handle and grip design. Stick packs have to fit into the handle and tend to be thicker than slide pack designs.

Beyond the handle diameter, we also look at how the tool fits in your hand along with how comfortable and secure the rubber overmold is. In the real world, someone with small hands will like a different style that someone with large hands. While we look for significant issues that will affect everyone, the handle size does not play a part in the scoring.

Feature Set

Sales 101 will teach you that every feature must have a benefit. When we look at the feature set to help determine the best impact driver, we’re looking for features that have tangible benefits. Here’s the standard list of what we look for:

  • Brushless motor
  • Number of standard speed modes
  • Special modes
  • App-based controls and tracking
  • LED light design
  • Bit ejection
  • Bit insertion
  • Belt hook

We also look for special features. Brushless motors require electronics that open the door to systems like Milwaukee’s One-Key, Bosch’s Connected control, and DeWalt’s Tool Connect. Some manufacturers like Makita choose to program helpful modes in rather than having you customize them. Of course, smart controls aren’t the only thing manufacturers add. We look for anything out of the ordinary that’s genuinely beneficial.


The value a tool offers will be different for everyone depending on what features, performance, and price you prioritize the most. Regardless, it’s the sum of what you get compared to the price you pay that determines the value for you. That’s how we give each impact driver a value rating.

Why Impact Drivers?

Impact drivers are the screwdriving champions of the world and have more fastening power and speed than drill drivers.

In general, they’re lighter and more compact than drill drivers. Many Pros use them in tandem with a drill driver to drill a pilot hole and drive a fastener without switching bits. They also drive without transferring rotational torque to your wrist. This makes them ergonomically desirable for high-torque driving applications.

I think you forgot the Masterforce oil impulse driver. I don’t see it dethroning the Makita, but it would be nice to see how it stacks up. Especially against the Ryobi.


How exactly do you consider the makita oil impulse driver better than the milwaukee surge? The milwaukee is smaller, more powerful, quieter and has better warranty?
Am i missing something here?


the xdt16 is an amazing tool, like the most powerful 12v or the most compact 18v. you can get a real deal JAPANESE-MADE one if you grab the TD171, they made it for other markets and you can get them in a million colors. I got a dark red one and it still has kanji on it, i do not like chinese made!!

If you look around you can find deals on the new red Craftsman v20 stuff at lowes and eBay. Lowes constantly has deals where they give away free batteries or half price tools. It’s made by Black and Decker and very similar to dewalt. It might cost a hair more than harbor freight . The warranty is way better and the tools work well.


Is there a spreadsheet available somewhere that shows the scores for each ID you tested? Am I missing it? I recently purchased the Rigid Pulse Driver, and am pretty happy with it thus far. Problem, however, is that I never owned an impact or pulse driver prior to this, and am wondering if I opted for more power than I really need for a general homeowner and DIYer. Will I use it to drive lag bolts and do some basic automotive work? Definitely. But do I really need that much power, and could that $199 (I bought the kit w/… Read more »
