Choose a power drill by matching it to your most frequent tasks, then weigh cordless vs. corded, voltage, and chuck size.
The right starting point for most DIYers is a 7- to 8-amp corded drill or an 18- to 20-volt max cordless model, but the best pick depends on your projects.
Cordless or Corded: Which Should You Buy?
Choose a cordless drill for mobility and everyday household tasks; a corded drill for continuous power, frequent all-day use, or heavier materials. Cordless models run on lithium-ion batteries for work anywhere—up a ladder or under a sink—but trade-offs include runtime and weight. Higher-voltage cordless drills are often bulkier, so hold one with the battery installed and test overhead balance before committing. Corded drills deliver steady, unlimited power without battery fade, and are typically cheaper and lighter for the same output. The downside is the cord itself tethering you to an outlet.
What Voltage And Chuck Size Do You Really Need?
Voltage is a rough power guide, not a guarantee. A 14.4-volt drill from one brand can be stronger than a 12-volt tool from another, so compare model ratings and test results. For general household use, 12V to 20V cordless drills cover most homeowners, handling shelf mounting, furniture assembly, and light repairs. If you drive heavy screws, lag bolts, or drill into brick and concrete regularly, step up to an 18V model or add an impact driver.
The chuck—the three-pronged clamp holding bits—matters just as much. A 3/8-inch chuck handles general tasks like drilling into drywall and softwood; a 1/2-inch chuck accepts larger bits for heavier work without swapping tools. Keyless chucks let you change bits by hand in seconds; SDS chucks on rotary hammers lock bits firmly for masonry.
Key Features To Look For
- Variable speed and torque settings let you drive fasteners without stripping heads.
- Battery platform compatibility—staying on the same brand lets you share batteries across tools.
- Kit contents—two batteries, a charger, and a case usually beat a bare tool you must accessorize.

How To Avoid Common Buying Mistakes
Most drill regrets stem from predictable errors. Buying by voltage alone ignores test results and build quality. Overbuying power wastes money and adds weight; underbuying for masonry leaves a tool that stalls. Ignoring weight and grip comfort is the quiet killer for overhead drilling. Forgetting to check if the kit includes batteries and a charger turns a great price into hidden expense. And the wrong bit or chuck size guarantees frustration no matter the drill. Safety stays simple: wear safety glasses, use hearing protection for extended hammer-drilling, and clamp the workpiece. In hardwood, drill a pilot hole slightly smaller than the screw diameter to prevent splitting.
| Task Type | Recommended Drill | Why It Fits |
|---|---|---|
| General household use | 12V to 20V cordless | Mobility and enough power for shelves, repairs, and assembly |
| Heavy screws or lag bolts | 18V cordless or impact driver | Higher torque drives larger fasteners without stalling |
| Masonry or concrete | Hammer drill or impact driver | Hammer action and impact force break through hard materials |
| Frequent, all-day heavy work | Corded drill, 7-8 amps | Continuous power with no battery fade |
Match your drill to the material and hole size, and keep the bit perpendicular unless the project demands an angle. Start with your three most frequent tasks, set a realistic budget, and check what is in the box—that process, not marketing claims, is how you get a drill you actually reach for.
FAQs
Is a 12V drill enough for home use?
Yes, a 12V cordless drill handles most household tasks like hanging pictures, assembling furniture, and light repairs. It is lighter and easier to control than higher-voltage models, making it comfortable for beginners. Step up to 18V or 20V only if you regularly drive large screws or drill into harder materials.
What does a hammer drill do that a regular drill doesn’t?
A hammer drill adds a pulsing, hammering action to rotational drilling, letting it break through masonry, brick, and concrete that stall a standard drill. For occasional masonry, a hammer drill works; for frequent concrete drilling, a rotary hammer with an SDS chuck is the more durable choice.
Should I buy a drill kit or just the bare tool?
A kit with two batteries, a charger, and a case is usually the better value—two batteries keep you working while one charges, and the case protects the investment. Buy a bare tool only if you already own compatible batteries and a charger from the same brand platform.
