A battery drill is used for drilling holes and driving or removing screws, making it the most versatile tool for home projects, assembly, and repairs.
Whether you’re hanging shelves, assembling flat-pack furniture, or installing window treatments, a battery drill is the tool that gets the job done. Unlike a corded model, it runs on rechargeable batteries, so you can work anywhere—no outlet required. If you’re ready to buy one, our roundup of the best battery powered drills for home use covers tested top performers.
Core Uses: Drilling And Driving
A battery drill has two main jobs: making round holes and driving or removing screws and other threaded fasteners. That covers most everyday DIY tasks around a house.
Common tasks include:
- Drilling pilot holes in wood to prevent splitting.
- Driving screws into wood, drywall, and pre-drilled metal.
- Drilling holes in wood, metal, and plastic with the correct bit.
- Light masonry work when the drill has a hammer mode.
- Assembling furniture, hanging shelves, and replacing fixtures.
How A Battery Drill Works
A cordless drill uses a motor, a chuck that holds the bit, a battery pack, and a trigger for speed control. Most models have a reverse function, which lets you remove screws as easily as you drive them.
Types: Standard Drill vs. Impact Driver
There are two main types you’ll see: the standard cordless drill and the impact driver. Popular Mechanics explains the difference: a standard drill handles general drilling and driving, while an impact driver delivers high torque for heavy-duty screw driving in wood, metal, or cement. For most general tasks, a cordless drill-driver is the right tool; choose an impact driver when you’re doing serious fastening work.
Choosing Voltage And Bits For The Job
Voltage determines power. A 12-volt drill is fine for light work like assembling RTA furniture and hanging shelves. An 18- or 20-volt drill meets most home needs, including installing window treatments and fastening heavy artwork to wall studs.
Matching the bit to the material is essential. Use drill bits for holes in wood, metal, or plastic, and driver bits for screws, bolts, and nuts. RS Components notes that using the right bit and reverse rotation lets you remove screws as easily as you drive them.
| Voltage Class | Ideal For | Limits |
|---|---|---|
| 12V | Light duty: furniture assembly, hanging shelves | Struggles with dense wood or long screws |
| 18V/20V | Most home tasks: fixtures, wall studs, decks | Heavier and bulkier than 12V models |
Safety And Practical Limits
Using the wrong bit or mode can damage material or reduce control, so match the bit to the task. A standard drill isn’t a dedicated masonry tool; hammer-drill mode handles brick and lightweight concrete, but heavy concrete work calls for a rotary hammer. Cordless drills depend on battery charge, so keeping a spare battery charged is part of the deal.

FAQs
Can a battery drill be used as a screwdriver?
Yes. A battery drill with a driver bit works as a powered screwdriver for most fasteners. Use a clutch setting to prevent over-tightening and stripping the screw head or damaging the material.
What’s the difference between a drill and an impact driver?
A drill spins to make holes and drive screws in a straight rotary motion. An impact driver adds hammering force for high-torque fastening in tough materials like dense wood or metal. For general home tasks, a drill is more versatile.
Can a battery drill drill into concrete?
Only if it has a hammer mode. That mode adds a pulsing action for brick and lightweight concrete. For heavy or reinforced concrete, use a dedicated rotary hammer or SDS drill.
