A corded drill draws power from an outlet and needs a safe cable route; a cordless drill runs from a rechargeable battery and needs a compatible charger and battery plan. Choose by where and how long you work, then compare the exact model's chuck, speed, motor, weight and included accessories.
The power source changes how you set up a drill. A corded model needs an outlet and cable route; a cordless model needs charged batteries and a compatible charger. Compare those requirements with the location and duration of your projects.
Compare the setup
| Drill type | What to plan for |
|---|---|
| Corded | Reach to an outlet, cord management, rated voltage and the product’s intended applications |
| Cordless | Battery charge, spare packs for longer work, charging time and compatibility with tools you already own |
DEWALT’s DWD112 is an 8-amp, 3/8-inch corded drill. Its DCD777 is a 20V MAX cordless 1/2-inch drill/driver with a brushless motor and a battery in the listed kit. These are examples of different designs, not a direct power comparison; compare motor and application specifications for the exact tools you are considering.
Compare the drill itself
Power source is only one choice. Check chuck capacity against the bits you plan to use, the speed range, torque settings, tool weight and whether the product includes a side handle or battery. The corded or cordless label does not tell you whether a model is a drill/driver, hammer drill or impact driver.
If you already own cordless tools, check whether a new drill shares the same battery platform and whether the kit includes a charger and battery. For a corded tool, compare cable reach with the places you work and follow the maker’s electrical and safety instructions.

Common questions
Is a corded or cordless drill better for home projects?
It depends on where the work happens and how long it runs. Compare outlet access, cord routing, battery charging and the exact drill's specifications.
Can a cordless drill run while its battery is charging?
Use the tool only as its manufacturer permits. Check the drill and battery instructions for charging and operation; the included charger and battery setup varies by kit.
Does a corded drill have more power than a cordless drill?
A corded label alone does not establish the tool's drilling ability. Compare the specific motor, speed, chuck and maker's recommended applications.
What should I compare besides the power source?
Check chuck size, torque and speed settings, tool weight, battery or cord setup, included bits and warranty for the exact kit.
