5. DEWALT Bare-Tool DCF880B 1/2-Inch 18-Volt Brushless Cordless Impact Driver with Battery

DEWALT Bare-Tool DCF880B 1/2-Inch 18-Volt Brushless… Last update on 2019-02-01 / Affiliate links / Images from Amazon Product Advertising API

Dewalt is an American company that manufactures tools for professional contractors. It is one of the leading power tool manufacturers in the world. The company makes a wide range of hand tools that are used for construction purposes. From drills to hammers and saws, it has everything you can think of. The brand has existed since 1924 and has been inventing efficient tools for years.

The brand is most famous for its XRP line of cordless tools. It sells at a premium but they offer better performance in all applications. The brand released its first brushless impact driver in 2012. Since then, it has come a long way and the current models are better than ever. The one we will be looking at today is the bare-tool version of the 1/2-inch 18-volt model.


This tool is an impact driver with a high level of power and speed. It has an efficient rotor that delivers 650 inch-pounds of torque. This amount of torque powers the tool to drive all types of fasteners into hard and soft materials with ease. The motor, which is brushless in nature, operates at 2,000 rpm. This speed allows the tool to deliver up to 2,800 impacts per minute.

All these figures are standard among all 1/2-inch 18-volt cordless impact drivers. What makes this model different is that it has 3 gear settings that increase or decrease the speed and power of the driver. The settings are low, medium, and high. They allow the user to adjust the performance of the tool based on the situation at hand. The low setting is ideal for driving small screws into soft materials. The high setting on the other hand is better for drilling and fastening large and hard materials.

The tool has a compact and ergonomic design that provides users with maximum control over the driver. It has an inbuilt hammer mechanism that allows it to perform light chiseling and demolition work. The handle has an anti-slip finish that ensures the user maintains a firm grip even when working with the tool for long hours. The front of the handle contains a built-in LED light that illuminates the surface you are working on. This is especially useful when you are working in darker areas.

On the top front of the tool, you will find the battery indicator. It displays the charge status of the battery with a series of green bars. A red bar will appear when the battery needs to be charged. The model comes with a 1.5Ah battery that provides an excellent runtime. It takes approximately 30 minutes to charge the battery and it lasts for up to 2 hours.

Buyer’s Guide

Below we have compiled a list of some of the things you should keep in mind before buying an impact driver.


The first thing you need to think about is what you will be using your new impact driver for. This may sound like a no-brainer but it is important to consider because the type of work you do will determine which features are more important. If, for example, you do a lot of work on your car then you will want an impact driver that has multiple speeds and a longer battery life. On the other hand, if you use it only for small DIY jobs around the house then power and speed are not as important and you can save money by going with a cheaper model.


When it comes to buying tools, most people don’t think about the brand. In fact, some people will even tell you that the brand doesn’t matter. This is not true when it comes to power tools because some brands are better than others. In fact, some are so bad that it is probably best to avoid them altogether. The best brands on the market today are Milwaukee, Makita, and DeWALT.

These companies have a long history of making high-quality power tools and they are usually what serious DIYers and professionals use. Of these three, the first two are probably the most well-known and popular but any of them will provide you with excellent results.


Impact drivers are available in a wide range of sizes. The smallest ones are smaller than a regular drill and are great for working in tight places. Larger ones are more powerful and are mainly used for heavy-duty jobs. It is best to think about where you will be using it most often and then choose a size from there. If you are a professional mechanic, for example, you will probably want to go with the largest one because having the extra power can prevent you from having to take time out of your day to swap out tools.

Battery Type:

Most impact drivers run on lithium-ion batteries nowadays and each one has its own pros and cons. Certain batteries, for example, hold a charge for longer periods of time while others can accept more power and reach higher top speeds. Most people usually have no problem choosing between the different types but if you are having trouble deciding then you should definitely consult a knowledgeable sales associate at the store.


Most people don’t think about this but an impact driver can get pretty loud. If you are going to be using it in an enclosed space then you may want to invest in a pair of earplugs. Most people don’t find this necessary when using an impact driver outside but it is up to you to decide what is best in your situation.


Last but certainly not least, you need to think about how much you are willing to spend on an impact driver. Prices can vary quite a bit from model to model but, as with most tools, you get what you pay for. If you are on a budget then there are cheaper options available to you. If money is not an issue then you can splurge on a more expensive model and enjoy additional features.

Impact Wrenches

Whether you are a professional or a hobbyist, an impact wrench will make your work easier and save you a lot of time.

Over the years, manufacturers have tried to improve on the design of impact wrenches but the main concept has remained the same. The motor of the tool drives a hammer on a pivot so that it slams into the bolt or nut from the side with amazing speed and force. This is able to provide up to three times the turning power of a standard wrench. You can definitely hear the difference in sound when an impact wrench slams into a nut or bolt.

The main advantage of using an impact wrench over a regular one is that it helps you to remove and tighten bolts and nuts with much less effort. Even if you are only loosening something that is already slightly loose, an impact wrench will save you a lot of effort.

Now you are probably wondering why every person with a toolbox doesn’t own one of these. The answer is twofold: Impact wrenches are more expensive and, more importantly, they are LOUD. If you need to drive in many screws or remove or tighten many bolts then an impact wrench will definitely save you time and effort but your neighbors will certainly hate you! If you value their friendship, you might want to buy a quieter (and less expensive) traditional cordless drill.

Electric impact wrenches are also known as impact drivers. They are built to loosen and fasten bolts quickly and efficiently. If you do any work that requires making a lot of holes or frequently disassembling and assembling things, then an impact driver is a great tool to have around.

The main types of impact drivers are corded and cordless. Naturally, the cordless models are generally preferred since you have more freedom of movement. However, cordless impact drivers tend to be a little bit more expensive than corded ones.

When choosing an impact driver, you need to consider the weight of the tool. Since you will be holding it in your hand and using it for long periods of time, you want to choose a model that is neither too heavy nor too light for your liking. Pick one that fits your hand and feels comfortable to use.

DeWalt, Hitachi and Makita all make popular models of cordless impact drivers. The models by these companies feature different designs but all incorporate an impact mechanism inside which uses the motor to drive a hammering mechanism on the tip of the bit. When you switch the tool on, this spinning hammer slams into the sides of the bit with great force to help it bore its way into hard surfaces. This provides the driving power that helps you to fasten or remove even the most stubborn of bolts and screws.

If you need to make a lot of holes, drive many fasteners or take things apart and reassemble them on a regular basis, then an impact driver is something that you should seriously consider buying. With an impact driver, you will save a lot of time and be more productive with your work.
