3. Makita XDT16Z 18V Impact Driver
Makita power tools aren’t always the cheapest, but the higher prices are often reflected in the performance, as is the case with the Makita XDT16Z brushless impact driver.
This is one of the most dependable tools in its class and comes with a wide range of enhanced high-tech features.
It is often said that the best impact driver is the impact driver that gives total control over the speed. The XDT16Z fits the bill with its four RPM ranges. That’s twice as much as the average impact driver.
Granted, all the ranges may seem a bit high on the top end. Regardless, you can get up to 3,600 RPM if you crank it up to max.
You can also adjust the number of impacts per minute within four different ranges for even more control over your driving. The highest IPM under no load is 3,800. The speed/power selector is conveniently placed under the collet or chuck.
But the brushless motor on the XDT16Z isn’t capable of just high speeds or beats per minute. It’s also responsible for delivering up to 1,600 in-lbs. of torque.
There’s also an auto-stop mode which helps when you’re loosening fasteners. There are many more good things to list about the XDT16Z, such as the ergonomic grip design, the comfortable trigger, the overall build quality, but it’s all to be expected from a Makita power tool.
What's to like about the Makita XDT16Z 18V Impact Driver
One of the best things about the XDT16Z is the built-in assistance. The A-mode, as it’s called, is a function that prevents cross-threading. It does this by driving at a lower RPM until it senses that the tightening has begun.

Type of impact driver
As opposed to their first cousins, driver drills, impact drivers have less complicated designations and don’t come in a variety of classes or types. One could simply classify impact drivers into four simple categories.
Corded impact drivers
Corded impact drivers are like any other corded power tool. They’re bigger and more powerful than their cordless counterparts, and you can use them continuously at the cost of some mobility.
Cordless impact driver
A cordless impact driver is easy to use, and it can be controlled for light-duty and heavy-duty tasks. The minor downside, of course, is that you’re always dependent on the battery and its charging time.
Another type or category of impact drivers is the brushless impact driver, which is called this because of its brushless motor. It’s a motor that operates without friction, which means that it’s much more reliable and doesn’t break down as easily, among other things.
Brushed impact drivers are the classic impact drivers with brushed motors. They are cheaper than their modern brushless counterparts but require more maintenance. Both brushless and brushed impact drivers can come in corded or cordless designs.
Impacts per Minute
The IPM number indicates the number of hammer blows that the impact driver delivers in 60 seconds. Therefore, higher numbers are indicative of faster pulses or bursts, which are ultimately responsible for driving those long screws into walls.
You might also be interested to know that some manufacturers use BPM (beats per minute), which is, of course, just another term for impacts per minute.
Rotation per Minute
Regardless of whether you’re looking at a light-duty or heavy-duty impact driver, the rotations per minute (RPM) or speed will be significantly higher than that of your standard drill driver combo tool.
The majority of impact drivers should be able to operate at multiple RPM ranges. Although seeing higher numbers tends to be eye-catching, you should know that variety is often better when it comes to RPM.
An impact driver with more RPM ranges and one that allows you more control over the speed should be better in performance than an impact driver that just has a very large RPM rating on the top end.
Also worth noting is that RPM is less indicative of performance than it is in the case of cordless drill drivers. For impact drivers, torque and IPM are sometimes more important. That’s because using too high of an RPM setting on an impact driver could cause stripping.
As is the case with most cordless power tools, voltage is used by manufacturers to indicate the power of an impact driver. Of course, those who took high school physics would know that power is the product of voltage and current, so the voltage alone may not say much.
Most impact drivers are powered by 12V, 18V, or 20V battery. So, which is the best impact driver out of these three categories?
12V impact drivers are generally reserved for light-duty work. They are certainly cheaper and lighter and have unique applications when working in tight spaces.
Secondly, 18V and 20V impact drivers tend to vary very little in terms of power. Just as it is with cordless drill drivers. The main difference between 18V and 20V impact drivers is this: The former is a rating that makes use of nominal voltage while the latter uses maximum voltage.
This means that for the most part, the actual power supplied by 18V and 20V impact drivers is about the same. Torque is not the same as power. It depends on the design of the motor and drivetrain, which also determines the RPM where the maximum torque happens. (You may notice a similarity to the torque rating of car engines and drivetrains there.)
Of course, compared to 12V impact drivers, 18V/20V models will offer more power. They will also be heavier and more expensive, but that’s just what it takes to work on heavy-duty tasks.
Current is often used to express the power in corded impact drivers. That’s because you already know the voltage (110 to 120V in the US but often assumed to be 117V) – multiply the current in Ampere by that, and you get the power in Watts. However, corded impact drivers are less sought after due to their lack of mobility.
Amp-hour (Ah) is the unit for battery capacity. It shows how many amps a battery can deliver continuously in one hour. So, a 2Ah battery can deliver 2A for one hour, 1A for 2 hours, 0.5A for 4 hours, 4A for 0.5 hours, you get the idea.
This means that the higher the Ah value, the longer the battery should last between charges. It’s worth mentioning that higher capacity batteries are also larger and heavier. They will also take longer to charge.
Impact Driver F.A.Q
How do you use an impact driver?
The first thing that comes to mind when operating an impact driver is having a supply of compatible drill bits. You’re much more limited with an impact driver than you would with a driver drill.
You'll mostly require specific 1/4-inch drill bits necessary to fit in the hex-shaped collet of the impact driver in order for them to work.
In terms of operating an impact driver, it’s much easier than a cordless drill since there are less adjustable settings. You don’t have to worry about torque adjustments for the most part, nor do you have to worry about keeping a very steady hand or injuring yourself.
Due to how an impact driver works, driving screws can be accomplished in record time.
How does an impact driver work?
There’s a simple principle behind the operation of an impact driver. A downward rotational force is applied directly to the screw to drive it into a wall, wooden frame, or other medium.
This action is similar to that of a hammer drill. However, with impact drivers, this force is applied in short bursts of significant torque. It’s important to understand that unlike manual impact drivers, automatic impact drivers exert a downward rotational force instead of a forward thrust.
Because of this difference, electric impact drivers are a lot safer to use than manual drivers or drill drivers.
What is an impact driver?
An impact driver is a high-torque power tool that can accomplish similar functions as cordless drills and more. Due to its design, the impact driver is often the preferred tool for most screw driving and tightening jobs.
And, because the torque is generally higher than what you get in a standard drill driver, an impact driver helps you finish the job faster.
What is an impact driver used for?
Most people use impact drivers to drive large fasteners such as long screws and lag bolts. This type of power tool is a go-to option for both light-duty and heavy-duty work in remodeling, art projects, metalworking, construction, and many other fields.
Apart from being able to drive large fasteners at superior speeds, an impact driver can also be used to drill very small holes in soft wood or light metal. However, for drilling purposes, an impact driver will pose some limitations, especially since most of them can only work with 1/4" hex-shank drill bits.
What is a brushless impact driver?
The terms brushed and brushless are used to describe the motor in power tools and other machinery. A brushless motor is a motor that operates without brushes, and is therefore frictionless.
Besides reliability and lifespan, friction and resistance can cause some issues with performance or efficiency. Therefore, brushless motors are known to offer superior reliability, energy transfer, heat efficiency, and more.
This means that a brushless impact driver is generally a more expensive power tool. But it is also one that gives the best results under continuous and long-term use.
If you’ve made it this far, you may find it easier to select your next impact driver with our final recommendation.
If you’re interested in purchasing a high-quality impact driver from an established and respected brand like Dewalt that can cover a wide range of applications, the DeWalt DCF 887B 20V Max Impact Driver might be the best impact driver out there.
