Frequently Asked Questions (FAQ)

Are corded drills more powerful than cordless?

Yes. Since corded drills are directly connected to electricity, they have unmatched power and endurance. Despite having the same variations, corded drills have the upper hand in each category; drill, hammer, and rotary. Cordless drills only use battery power, which is limited; thus can only handle small tasks.

What’s the difference between dcd777 c2 and dcd771c2?

DEWALT DCD777C2 is lighter, more powerful, and brushless.

Should I buy corded or cordless tools?

It solely depends on your buying requirements. If you want a powerful machine for heavy-duty tasks, I would recommend corded drills. However, in terms of flexibility and portability, cordless drills remain foremost among the two.

Should I avoid cheap corded drills and invest in better quality?

I honestly think that the correlation between price and quality is weak. This can only mean that cheap drills could have a better quality than more expensive ones. If it’s a question of price and quality, quality outweighs price requirements.

What voltage drill should I buy?

12-18 volts. This is the average voltage to sustain most activities around your house. Voltage lesser than this is suitable for minor tasks. A drill with a higher voltage will take on more difficult jobs due to its superior performance.

Does a higher voltage mean more power?

Yes, a drill with a high voltage consequently has high torque. Torque is the force that causes angular acceleration. When the force at which the drill rotates is high, the screwing speed is also high. This actively illustrates that a high voltage equals high power.

What kind of motor is in a corded drill?

Universal motors, which, according to their name, can be used on most hand tools, power tools, dryers, blenders, and many more. They are lightweight, have high speed, and are compact. They are uniquely designed for AC-powered devices that require a direct electrical connection.


This is where I take my stance after comparing DEWALT DCD777C2 VS DCD771C2. I support DEWALT DCD777C2. First, it is perfect for beginners and professionals.

On top of being light and compact, it delivers remarkable performance with 340UWP and 1750rpm speed.
