Years ago, if you wanted to use an impact wrench, you needed an air hose and compressor—and that was just the beginning of a long line of tool accessories that you’d have to drag out just to remove a few nuts or bolts. But with the advent of cordless impact wrenches you have all the power you need, in a convenient package, to loosen or tighten stubborn nuts and bolts. And with the DeWalt DC820KA 1/2″ (13mm) 18V Cordless XRP Impact Wrench, power is certainly what you’ll get. Whether you’re driving home a few lag screws or you need to loosen up a few rusty nuts, this DeWalt impact wrench is the perfect tool for the job.
The light, yet powerful design allows construction workers and DIY gurus alike to sport an impact wrench wherever they go—regardless of whether or not there’s a supply of compressed air around. Let’s take a look and see why it’s one of the best cordless impact wrenches on the market.
What Are The Features Of A Good Cordless Impact Wrench?
There are many features that help to make an impact wrench stand out from the crowd, but there is one important feature that I personally look for in an impact wrench, and that’s torque. Without the right amount of turning force, it’s going to be impossible to drive lag screws through tough lumber or remove stuck-on nuts from corroded bolts. But it’s not just torque alone that makes for a good impact wrench. Lets see how the DC820KA performs in each of these areas, as well as how it compares with the DW059K-2.
- High Speed Rotation
- Battery Power
- Replaceable Parts
- LED Lighting
- DC820KA vs. DW059K-2
What I really like about the DeWalt DC820KA cordless XRP impact wrench is that it has a lot of torque—and that translates into getting the job done easier and faster. With 1,740 inch-pounds of torque delivered straight to the driver via the all metal transmission, this DeWalt impact wrench has all the power you need for fastening or removing all sorts of materials and hardware. If you’re looking for a tool with a good amount of torque in a lightweight package, it’s hard to beat this impact wrench.
High Speed Rotation Delivers Plenty Of Power
The high-speed rotation translates into more torque—and delivers more power when you need it most. At 2,400 rpm’s, it has the desired rotation for creating the concussive blows (2,700 bpm) that are needed to really create a powerful turning force when you need it, or simply to spin the tool faster when high torque output isn’t required for the application.
One of the things I really don’t like about some 1/2-in. drive impact wrenches is that as the torque and rotation speed increases, so does the weight of the tool. And that can make for a heavy tool—especially when you factor in the weight of the battery pack. You might as well have an air hose attached if the tool weighs too much. But with the DeWalt DC820KA cordless impact wrench, you can be sure that your arm isn’t going to get worn out from lugging it around all day—it weighs in at just 4.6 pounds. And thanks to its small size, it can get in those tough to reach areas where other impact wrenches just won’t fit.
Good Battery = Long Run Time
Nothing’s worse than having to constantly recharge batteries when the tool uses up all of the power in just a few short hours of use. That’s why I find the DeWalt DC820KA to be a great cordless impact wrench. It sports a powerful 18V battery that’s also dependable so you won’t have to constantly switch out battery packs for recharging. And just in case you need the extra battery backup, the wrench kit comes with two batteries.
No matter where you’re using your DeWalt impact wrench, chances are, it’s probably not going to be well-lit. That’s why I always look for a built-in LED light on all my driving tools. Located conveniently above the anti-slip pistol grip and just below the heavy-duty magnesium gear case, it shines a bright light perfectly at the work area.
Replacement Parts For Easy Maintenance And Repair
Let’s face it: your tools are going to break down sooner or later. So rather than toss them in the trash and buy new, it’s much more economical to replace the worn out parts with new ones. But that can really be tricky if the tools aren’t designed with replaceable parts. And since many cordless impact wrenches have framed motor casings that prevent replacing parts, it’s easier to just them. It was created with a frameless motor and replaceable brushes so that you’ll not only be able to save money if something breaks down, but you’ll also be better able to maintain the tool throughout its life.
DC820KA vs. DW059K-2
While both of these great impact wrenches have powerful motors, durable designs and plenty of torque, they offer different features that make them useful for different projects. If you’re looking for an impact wrench that is lightweight and compact for getting in and out of tight spaces, then the DC820KA is the best choice. However, if you aren’t too worried about the size of the tool, then you’ll want to pick up the DeWalt DW059K-2 because it offers more inch-pounds of torque versus the DC820KA.

I prefer to buy my tools from Amazon as they not only have a good deal on DeWalt power tools, they also provide free shipping. On Amazon, the entire kit is in the $185 range, and it will arrive at your door in just a few days.
What Are The Complaints?
There’s always going to be some trouble with a power tools design or features and it wouldn’t be fair if I didn’t tell you about some of the complaints. If you’re going to be using this tool for serious impact work like removing lots of nuts or bolts from heavy equipment you may want to upgrade to a more powerful tool (such as the DeWalt DW059K-2). While it certainly provides the power to get the job done, the batteries might end up wearing out too quickly if the job requires lots of repeated high torque work.
What Are Other Owners Saying?
One of the best things about buying tools on Amazon is that they not only have great deals but they also have great reviews from real people who recently bought the item. Here’s what a few owners had to say about the DeWalt DC820KA impact wrench:

- “I work in a factory building gas tanks for the US auto makers; this tool has made many of my jobs a lot easier. It has just enough power and a perfectly light weight. The batteries last a long time. The lock pin on the anvil took a bit to get used to but now I’m glad it’s there because I never have a problem with sockets falling off. I would buy this tool again and I would recommend it to other people.”
- “I got this product because we use it in our factory. This product is abused and has to stand up to perform when required because we can’t afford downtime in our work place. The product is light and has plenty of torque.”
- “The DeWalt quality does not need any comment! The wrench is incredibly robust but light weight. The batteries have a very long lifetime, and are very quick to recharge. It’s amazing for tires bolts! Everything required by a good portable tool.”
- “We brought this for my little sister for her heavy duty fitter apprenticeship and it has taken everything that they have dished up to it”
Considering their low price and free shipping option, Amazon is the best place to buy this exceptional cordless impact wrench.
