Dewalt 20 Volt Cordless Drill Review
Although cordless drills are now ubiquitous, there was a time when the majority of drills available were solely A/C powered corded ones. The current crop of pro-grade cordless drill/drivers delivers the same amount of power as corded drill/drivers while also providing all-day runtime.
Battery and electronics advancements continue to improve power and performance, and the underlying mechanics of how a drill works have evolved substantially.
What You Should Know About Cordless Power Drills
A power drill is an electrical tool that is used to make holes in walls and other hard surfaces. Screws in walls and other surfaces can also be fixed using them.
All power drills have a main body with an electrical motor, a handle to keep the tool steady, and a chuck mechanism to hold the drill bit in place. A safety switch, an on/off switch, a speed control, and a reverse switch are among the controls.
Electrical power is supplied through a connected electrical cord to all heavy-duty drills. Nickel-Cadmium (Ni-Cd) or Lithium-ion rechargeable batteries power the cordless power drills we discuss in this article. Let’s have a look at how these devices work.
What Is a Cordless Drill and How Does It Work?
When it comes to knowing how cordless power drills function, there are two main questions to consider. The first is, “How is the drill bit’s circular torque motion possible?” The second question is, “How does the drill obtain its power?” Let me first respond to the first question before moving on to the second.
An electric motor contained inside the drill bit provides the torque or rotating force that drives the drill bit. The motor operates on the concept of magnet poles repelling each other.
When you put two north poles of two magnets together, or two south poles of two magnets together, they repel each other, as you probably discovered while playing with wall magnets. This is the same process that causes a torque to be generated in an electric motor, which is then translated into drill bit motion.
A motor is made up of a permanent magnet and a metal rotor mechanism. This rotor is a metal item with electrical wire looped around it. When an electric current is applied to the rotor, it transforms into an electromagnet.
Both magnets’ similar poles oppose each other, creating a torque that turns the rotor. The rotor has a switch mechanism, also known as a commutator, that continually reversing the direction of current supplied to the rotor, allowing it to keep rotating.
The drill bit is driven by a revolving axle with the torque provided by the gear transmission. As a result of the electric power supplied, a magnetic field is created, which drives the rotor to give torque.

Dewalt DCD771C2 Review
The Dewalt DCD771C2 is one of the greatest cordless drills on the market today. The Lithium-ion battery in the 20-volt cordless drill is powerful enough to drive the high-performance motor.
Dewalt is a leading maker of tools that are not only essential but also well-built to tackle even the most difficult drilling operations. As a result, the Dewalt DCD771C2 is made of strong materials that can resist most drilling tasks.
With the high-speed transmission and two changeable speeds, the user can select the amount of performance desired for specific applications. This tool is really useful due to the speed variation.
This Dewalt DCD771C2 cordless drill review will tell you everything you need to know about this high-quality drilling equipment.
It is equipped with a 2-speed transmission with a speed range of 450 to 1500 rpm. This means it can spin at a maximum of 1500 revolutions per minute under no stress, but at low rates, it can spin at 450 revolutions per minute. This tool can give outstanding power output because of the varying speeds. Furthermore, the varied speeds let users complete a larger range of drilling activities while staying on schedule.
Because this is a one-handed drilling machine, vibrations and strain are kept to a minimum even after extended periods of continuous usage. It has an ergonomic grip that is both comfortable to grasp and improves machine control and mobility. This gives you confidence when it comes to drilling.
Compact and lightweight
The Dewalt DCD771C2 has a tiny design that allows it to fit into tight spaces while being held in one hand. It is light enough to be held in one hand and weighs 3.64 pounds. Furthermore, you can work constantly for an extended period of time without being exhausted.
Powerful with Quick Charging Battery
This drilling tool is powered by a 20-volt lithium-ion battery, which is considered to be an upgrade above the typical 18-volt batteries used in most drilling equipment. This tool is arguably more powerful and has a longer range than the 20V.
The best part is that this battery charges quickly, taking anything from 30 minutes to an hour to fully charge. To avoid overcharging and to ensure long battery life, the process automatically ends after the battery is fully charged.
It also has an LED light above the trigger switch. Despite its modest size, the LED light produces enough light to illuminate any dark spot where you wish to drill. This light comes in handy, particularly while drilling in dimly lit areas.
Although the Dewalt DCD771C requires no special maintenance, it should be kept clean and stored in its bag after each use. This will increase the drilling machine’s longevity.

What We Didn’t Like About this Drill
The fact that this is an impact driver rather than a hammer drill is regrettable. As a result, it’s not recommended for drilling concrete. Even on the porous concrete surface, even with its hammer setting, it is ineffective.
How To Keep Your DeWalt Power Drills In Working Order
Even the best tools will eventually fail if they aren’t properly maintained, which is why many seasoned contractors will repeat the old saying, “take care of your tools, and they will take care of you.
When someone’s livelihood is dependent on their tools, a broken tool could mean losing a day’s salary. Even if you only use your DeWalt equipment for weekend DIY projects, it might be disheartening to be ready to get started only to discover your drill is broken.
These simple tips will keep your drills in good working order and ready for any project you have planned:
Store your drills in a dry location.
Drills, like the majority of DeWalt tools, don’t like water. Because water may quickly rust the chucks and inner parts of your drills, including the engine, you should store them on a shelf or workbench away from water.
Make use of sharp bits.
It goes without saying that a sharp bit not only drills through the material faster and easier but also puts less strain on the drill itself.
Allow a hot drill to cool down.
Even though DeWalt tools are built to last, they do require a break now and then. Allowing it to overheat is dangerous, so take a break every now and then if you’re drilling through a particularly tough material or using it for an extended amount of time.
Clean your drill after a long period of use
Although most DeWalt drills have an enclosed casing, there are ventilation slots that should not be allowed to become clogged; blow them out with condensed air to keep them clear of debris and wood chips.
You should also inspect the tool’s outer casing for fractures, the power cord insulation for tears (if applicable), and the chuck for lubricant.
Keep your drill off the ground
If you’re working on a project outside, keep your drill above the ground so dirt and grass clippings don’t get inside the casing.
If there’s a chance of thunderstorms or rain and you might not have time to gather all your tools, it can be a good idea to have a sheet of plastic or a tarp close by and ready for use.
Always read the operating manual supplied with your DeWalt tool as there may be maintenance instructions for the specific model you purchased and there should also be directions on how to get your drill serviced if more than routine maintenance is needed.
Dewalt is a well-known name in the world of powered tools, particularly in the small drill market. The Dewalt DCD771C2 is a powerful machine that speaks the Dewalt design language. This drill isn’t the cheapest, but its compact design and construction put it in the middle of the pack.
If you’ve been debating whether or not to acquire this instrument, we hope this cordless drill review has shed some light on the subject. It is, without a doubt, the greatest cordless drill for DIYers and novices looking to enhance their drilling skills.
