A drill driver and an impact driver can both drive screws, but they deliver force differently. A drill driver turns steadily and lets you control speed and torque. An impact driver adds rapid rotational blows when resistance rises, helping with long or stubborn fasteners. Choosing well comes down to what you fasten, how often you do it, and whether you need to drill holes as well as drive screws.
What we cover
The quick answer
For a first or only tool, choose a drill driver. It handles ordinary screws, pilot holes and general drilling with more control, and its chuck accepts a wide range of round- and hex-shank bits. Choose an impact driver if you regularly drive long screws or structural fasteners, or if you want a compact tool that keeps moving when a drill driver starts to struggle.
If you already own a drill driver, an impact driver is a useful second tool, not a replacement for it. If you mainly assemble furniture, hang shelves or make occasional repairs, the drill driver is usually enough.
How the tools differ
A drill driver uses a chuck that tightens around the bit. Its clutch slips at a chosen setting when resistance gets high, which helps prevent stripped screws and damaged materials. It is easier to feather into a delicate task, such as drilling a clean hole or driving a small screw into a cabinet.
An impact driver usually takes 1/4-inch hex-shank bits. It applies short rotational impacts as the fastener meets resistance. Those impacts can deliver more turning force without the same steady twisting load on your wrist, but the tool is noisier and can be harder to control. Use impact-rated bits; ordinary bits can snap under repeated impacts.
Side-by-side comparison
| Task or feature | Drill driver | Impact driver |
|---|---|---|
| Driving cabinet or furniture screws | Better control; clutch helps limit overdriving | Works, but easy to strip a screw or damage the surface |
| Driving long deck or construction screws | Can work, but may stall or twist in your hand | Usually faster and less likely to bog down |
| Drilling ordinary holes | Best choice; accepts common drill bits | Possible with hex-shank bits, but less controlled and less convenient |
| Bit compatibility | Broad range of round- and hex-shank bits | Primarily 1/4-inch hex-shank accessories |
| Noise and feel | Quieter, smoother operation | Louder, pulsing impacts; hearing protection may be sensible indoors |
Choose a drill driver for holes and careful work
A drill driver is the more versatile single-tool purchase. It is the straightforward choice for drilling pilot holes, installing wall anchors, assembling furniture and driving smaller screws into wood. A clutch with multiple settings is especially helpful: start low, then raise the setting only if the screw stops before it is seated. The numbers are not standardized torque values, so test on scrap material rather than assuming a setting will suit every screw.
For drywall, drill a pilot hole only as large as the anchor instructions call for. Oversizing the hole can leave a plastic anchor spinning instead of gripping. For a small screw in softwood, a pilot hole also reduces splitting; match the hole to the screw’s core diameter, not its full outside thread diameter.
If you need one cordless tool for mixed household jobs, look at a cordless drill driver kit. A lower-priced drill driver is often fine for occasional use. Prioritize a comfortable grip, variable-speed trigger, clutch and a battery platform you can use with other tools over a long list of features.
Choose an impact driver for frequent fastening
An impact driver earns its place when you repeatedly drive long screws into framing, build a deck or fasten thick stock. A drill driver may handle a few 3-inch screws in softwood, especially with pilot holes, but it can stall as resistance rises. An impact driver is less likely to stop mid-fastener and often lets you work faster across a run of screws.
That added force comes with a trade-off. A fastener can sink below the surface, strip its head or split wood before you react, especially at full trigger speed. Start slowly, hold the tool square to the screw and ease off as the head approaches the surface. For delicate work, use a drill driver or practice on an offcut first. Use the bit type that matches the screw head, and replace worn bits; a slipping bit chews up the recess and makes removal difficult.
For regular construction fastening, consider an impact driver kit with a battery and charger. For occasional long screws, borrowing one or buying a bare tool that matches batteries you already own may be better value.
Drilling, masonry and accessories
An impact driver is not a substitute for a drill driver when you need clean, accurate holes. It can turn suitable hex-shank drill bits, but its pulsing action offers less control, and many common drill bits have round shanks that will not fit its quick-change holder. A drill driver is also the better choice for larger holes where a hole saw or auger bit may catch suddenly. If that happens, stop and reposition rather than forcing the tool.
For brick or concrete, neither tool is ideal for frequent drilling. Use a hammer drill with a masonry bit and the correct wall plug or anchor for the material. Do not use the hammer setting on tile: it can crack the surface. Check for pipes and cables before drilling into walls, and follow the anchor maker’s hole diameter and depth instructions.
A practical buying checklist
Before choosing, think about your next few jobs rather than the biggest task you might do once. If they mostly involve holes, anchors and small-to-medium screws, a drill driver is the sensible buy. If they involve many long fasteners and you already have a drill for holes, an impact driver adds useful speed. If you often do both, a two-tool kit lets you keep a bit in each tool and switch without changing accessories.
Compare battery cost as well as tool price. A bare tool can be a bargain if it fits a battery platform you own; starting from scratch, a kit may cost less than buying the battery and charger separately. Avoid paying extra for a high-output tool if your work is occasional and light. Good bits, the right pilot-hole size and steady technique often matter more than maximum torque.
