Cordless Impact Drivers can be challenging to shop for since each brand measures their tools differently, which makes it difficult to comparison shop.
A good example of this is how Dewalt has created a brand-specific metric called “unit watts out” (UWO). No one — except for some nerdy engineers –knows what UWO means as a comparison metric.
Here at Tool Tally I’ll help you sort through the craziness and the brand wars and purchase the best impact drivers. We dove deep, bought some impact drivers, and put together this 3,600+ word article. (~12-minute read). Keep reading to review what we learned.
Ever used a hammer drill?
I remember just a few years ago when my electrician friends would complain about having to drill all the holes for running home runs on a new build.
The hammer drills were heavy, loud and torturous to use.
A few months ago, I was working a job site with one of them, and predrilling holes for home runs with a small, Dewalt cordless impact driver. It handily drove the spade bit through 6 inches of wood, hole after hole. These little power tools are revolutionizing the lives of plumbers, electricians, and repairmen.
Hammer drills are slightly different from cordless impact drivers in that the bit also goes in and out slightly. We kept a hammer drill in the truck for going through concrete, but the cordless impact driver was doing most of the work.
Makita XDT12Z 18 Volt LXT with Brushless Motor: The Best Impact Driver
Bosch brags about having the smallest tool, but at only 4 and 5/8″ long, I think Makita might be beating Bosch at the compact game. They are also winning in the weight game, coming in at about half a lb lighter.
When talking about powerful cordless impact drivers, the Makita XDT12Z deserves to be near the top of the list.The device has set new standards in an already growing market. The tool features a high torque output as well as a higher speed than the competitor’s models. It can deliver about 1550 in-lbs of maximum torque.
Whether you want to work with cabinet screws or lag bolts, the Makita’s 4-speed power selector makes it easier to use the tool for a wide range of applications. Furthermore, it features an exclusive technology called the Quick-Shift Mode. Often, when driving in a screw, you might need to slow down the driver to ensure no damage takes place. The Quick Shift mode automatically reduces the impact speed just before driving the screw.
This means lesser stripping and damage to the screw as well as the work.
Also featured is an Assist Mode that helps eliminate any cross-threading. It does so by driving the fastener at a lower speed until the tightening process begins. Furthermore, the Tightening Mode allows for faster tightening to increase your confidence when working quickly.
In review: You are likely a Dewalt or Milwaukee fan, but with all of these features at this price tag time for the dedicated woodworker to retire those colors and buy some teal green jerseys. Makita is leading the way in innovation on their cordless power tools, and their engineering is designed to help you work faster and more efficiently.
- 3.0 Amp hour batteries are some of the longest-lasting
- Features multiple modes that allow for efficient fastening without any damage
- Cordless operation for easier maneuverability
- Compact and lightweight
- Ergonomic design, enabling you to use it for hours
- High torque output
- Everyone is going to be trying to borrow it. Especially your teenage son.

Best Impact Driver Buying Guide
How Does an Impact Driver Work?
You have the Impact driver and the impact wrench.
Their power is measured in foot-pounds (ftlb of torque). They are designed with square drives to hold sockets, and they are used to work with nuts and bolts. Breakaway Torque is extremely important with impact guns.
The Impact driver (what we talked about on this page) is smaller and lighter. Typically their power is measured in inch-pounds. They accept bits for drilling into wood. They can be affixed with specially designed sockets for tasks such as drilling lag bolts.
Both of these tools have internal “hammers” that repeatedly strike to create thousands of tiny microbursts. This helps you create an aggressive concentration of torque without stripping out the head of your screw.
Drills are still very handy for drilling holes and quickly attaching screws to the wood. However, the hammering action of an impact drill means that you aren’t as likely to slip out of the head of a screw. As a result, more people are turning to impact drivers as their primary, all-in-one tool.
One note is that drills have “chucks” that allow them to accept bits of many sizes. Impact drivers only accept 1/4 inch hex bits.
How to Choose the Best Impact Driver for Your Build
If you’re a beginner looking for a powerful impact driver, chances are you might be confused! The overwhelming choices on the market, the endless review websites, as well as the extensive features each tool offers, is enough to leave anyone winded.
Lucky, we have listed down how to choose an impact driver efficiently, which is perfect for you! So, the three steps to choose an impact driver are as follows:
Design a Budget
You can find the perfect tool only to find out it is way out of the budget. Of course, the more expensive options are much more durable and might deliver more power. However, that’s not always the case. You can almost always find reliable tools that are much less costly.
Most impact drivers range from $100 to $300. The significant difference to look out for is between the battery life (measured in amp hours) and the torque delivered. Other than that, brand name and warranty are the other determining factors. The contractor grade tools of Makita, Dewalt, and Milwaukee often put these brands at the top of the list. Craftsman and Bosch are a couple of other well-known brands with excellent warranties.
Determine Type Of Use
The use of an impact driver heavily depends on the operator. If you are installing decks all day long, you will likely want to invest a little more in your equipment than the contractor who mostly does sheetrock work.
Impact drivers are great for drilling holes with spade bits. I’ve even used them with a 2-inch hole saw on plywood.
Another point to note is that the use of an impact driver is not just limited to drilling or fastening. You can add a socket adaptor as well as socket-ready chucks to convert the driver to a cordless impact wrench kit (albeit with much less power). This helps you in tackling the more heavy-duty jobs.
Max Torque is one of the most significant measurements on these tools. Make sure to get a tool with enough torque for your tasks.
Review Warranty and Support from the Company
Since these are highly technical tools, the slightest of misalignment can stop them from working efficiently. Therefore, you need to ensure that the company offers the best and fastest customer support on the market.
This includes warranty and trial periods. Not all companies offer a trial period; however, almost all companies offer at least a year of warranty. Buying an impact driver is an investment, and so you should ensure that the investment remains secure. So, we recommend you look for at least one year of warranty.
Also, look for instruction manuals and how comprehensive they are. The easier to understand the better. This is especially important for beginners who are just starting with an impact driver.
Is it A Bare Tool Or A Kit Best?
For my shoppers who haven’t bought cordless tools online before, this is an important point. A lot of times the best cordless impact drivers are sold as “bare tool.” This is excellent for the individual who already has batteries and chargers for that brand.
However, if this is your first purchase of that brand, you will want to purchase a kit. This will include a carrying bag as well as the batteries and chargers you need.
The batteries will work with other tools of the same brand. On future purchases, as you expand your workshop, you can merely buy bare tools to save money.
Review Motor Types
One of the biggest debates in the power tool industry is the Brushless vs. Brushed motor debate. Some prefer one to the other. However, most experts agree that the brushless motors are far more superior concerning functionality and efficiency (less strain on the battery).
Brushless motors do not use brushes to transmit the energy generators which is the norm with brushed motors. Using brushes for energy transmission can result in friction and loss of energy due to heat. So, brushless motors run much more efficiently and produce much less heat.
Secondly, Brushless motors do not require more maintenance (no brushes to replace) and so they last longer!
Lastly, they support smart electronics to help optimize performance and protect the battery from overload.
However, they tend to be much more expensive. Of course, you can always go for a brushed version, but you’ll be compromising on longevity for a lower price.
Most impact drivers come in either 18 V or 12 V models. Some might say they offer 20 V; however, that is far from the truth. They might deliver 20 V maximum voltage, but the nominal working voltage will be 18V. The critical differences between a 12 V and an 18 V battery are:
12V: They are more suited for light-duty DIY work. You can use them to drive fasteners into medium-grade materials. Most 12 V drivers are quite small and compact.
18V: These drivers are suited for professional and daily applications. They deliver much more torque and hence can be used on larger fasteners.
Impact Driver Battery Type
There might be various types of battery in the market, but perhaps none can beat the longevity of the Lithium-ion battery or Li-ion battery for short. You’ll find most batteries are rated at about 1.5–5 Ah. The higher the Ah, the longer the battery will last between charges.
Speed Of Charging Time
No one wants to wait around while their tool gets charged up. So, look for the charging time for the battery as well. Anywhere near 45–60 minutes is ideal.
Impact Driver Weight
Heavier impact drivers can make it hard for you to maneuver it. If you’ll only use the tool occasionally, then you can go for a heavyweight version as you won’t hold it for long. But, for more extended use, we recommend going for a power tool that is under 4 lbs.
Control Torque with Clutch Type
There are various types of clutches available with most power tools. However, almost all impact drivers come with adjustable clutches or electronic clutches that can help you precisely control the torque you put behind the tool. This makes it easier to do precise work, without damaging the screw or the surface.
Trigger and RPM Control
A variable RPM (rotation per min) control trigger helps you control the fastening process, so it does not damage the screws or the surfaces. Most tools have RPMs ranging from 0 to 3000 or even higher. They mostly allow at least 3 or 4 different RPMs. The speed can be controlled by a trigger so you can avoid stripped screw heads and damaged surfaces.
The Best Torque and IPM Control?
Torque and IPM (Impacts per minute) are the two significant factors to consider when buying an impact driver. Most 12 V tools deliver about 800–1200 in-lbs. of torque while the 18 V versions can deliver up to 2250 in-lbs.
Impacts per minute (IPM) can help loosen the most stubborn of screws. So, IPM needs to be considered as well. For 12 V tools, an ideal IPM of 2200–3500 IPM and for 18 V tools, an ideal IPM of 1700–3750 IMP is to be expected.
