Review: DEWALT DC827KL 18-Volt 1/4-inch Lithium Ion Impact Driver Kit with NANO Technology

The DeWalt DC827KL impact driver stands out for it’s lightweight, compact size and for it’s ability to keep you from experiencing typical arm fatigue.

Impact drivers come in many styles and sizes. Before you buy an impact driver, take a look at the DeWalt DC827KL, it will be worth your time. Why? For such a small impact driver it has many advantages in design and technology, all of which will put a smile on your face while you work on your next project.

In this review, we’ll take a look at the features and specs of this compact and versatile impact driver, and we will also take a good look at the impressive battery life.

Lightweight Size and Compact Design

The DeWalt DC827KL impact driver weighs in at only 3.7 pounds, with battery – it’s lighter than most impact drivers of comparable size and power.

The light weight of this impact driver is a result of it’s compact design and it’s use of a Lithium Ion battery.

The compact design allows you to maneuver and position this drill in many ways, and it makes it easy to reach into spots that are typically tough to work in. You will be able to get into some surprisingly tough to reach spots with the small size of this impact driver, and that’s no lie.

Also, the Lithium Ion battery doesn’t weigh as much as a comparable NiCad battery, and it’s smaller in size. In fact when holding the battery in hand it might be hard to believe that it is actually a new battery holding a full charge due to the weight difference. We’ll get into more about the battery later.

Another factor that comes into play with such a lightweight, maneuverable drill is it’s ergonomics.

Impact Driver Ergonomics

The form of the DeWalt DC827KL is designed to ergonomically fit the form of your hand, for added comfort and further reduced fatigue from extended use.

There is also an anti-slip grip to help your get a better hold on the drill in demanding situations.

The combination of this ergonomic design along with the light weight are what makes it such a maneuverable impact driver. Imagine trying to hold onto a drill for several hours of driving screws into a new deck. Ergonomics sound pretty good when you hit the 2 hour mark and your arms start to tire, don’t they?

What’s So Great About The NANO Technology and Lithium Ion Batteries?

If you haven’t used a Lithium Ion battery with NANO technology yet, you are in for a big surprise.

DeWalt DC827KL Impact Driver Lithium Ion Batteries

There are many advantages that come with upgrading to a tool that has this type of battery technology.

  1. The first advantage is that there is a much more flat self-discharge rate over the long haul. These batteries will simply not lose as much capacity over time as you get more and more use out of it.
  2. The second advantage is that these batteries can provide a a lot more sustained amperage than comparable batteries. This is an advantage in that when your power tool is demanding the most energy for a sustained period of time (aka: when you’re cranking on something really hard with your drill).
  3. The third advantage is a much higher cycle life than other types of batteries. This means that you can charge and recharge these batteries many times and not lose a whole lot of battery power and efficiency. Remember how your old batteries didn’t seem to last as long or have as much juice after recharging them many times? This effect is far less noticeable, if noticeable at all, with these Lithium Ion batteries.

The battery can be recharged up to 2000 times according to manufacturer specs. If you ever get a chance to recharge one of these 2000 times to find out if it actually lasts this long, let me know. It’ll take me a while to get that far myself.

These batteries might not have the total capacity that some other batteries on the market have, but they are extremely efficient and pack a great punch with power, quality and consistency.

A Powerful Punch

The DeWalt DC827KL has plenty of power for it’s size, and it can stand up to just about any job that you can throw at it.

How powerful is it? Let’s take a quick look at the power specs:

  • 1,300 in-lbs of max torque (111 ft-lbs)
  • 0-2,400 rotations per minute
  • 0-2,700 impacts per minute
  • 18 Volt power

There are no adjustable torque settings, but that is a minor thing to nag about with this impact driver. Certain users have reported that this driver is powerful enough to twist the heads off of torque screws when they really tried to put some power down.

And, despite all the power, this drill is still easy to handle and maneuver.

Other Notable Features/Specs

Enough about the power and battery already, huh? What about some of the other specs?

  • 1/4″ hex shank quick release
  • 5 3/4″ total tool length (that is small! you can see how they say this will get you into some tight spaces)
  • Replaceable brushes
  • Textured anti-slip grip
  • Magnesium gear case with all-metal transmission
  • Heavy-duty impact mechanism (directs torque to fastener without kickback)
  • Frameless motor

Basically, this is a quality tool. It’s built for heavy duty applications and longevity.

What’s in the Kit?

This is an impact driver kit, after all, so what do you get?

  • The DeWalt DC827KL Impact Driver
  • 2 18v Batteries
  • A 1 hour charger
  • A kit box

In addition to these items, you also get a warranty package that includes the following:

  • 3 year limited warranty
  • 90 money back guarantee
  • 1 year free service contract

This should be plenty of warranty to help you work out any bugs that your new tool might have. With DeWalt’s reputation for quality, however, there probably isn’t much to worry about.
