A cordless drill is the better all-around tool for most household jobs. An impact driver is faster and easier on your wrist when you’re driving lots of screws, but it’s noisier, less controlled, and not a substitute for a drill when making clean holes. If you’re buying one tool, start with a drill. If you regularly drive long screws or build projects, adding an impact driver can save time and effort.

What we cover
What each tool does
A cordless drill turns a chuck that grips round-shank bits. Its smooth rotation and adjustable clutch make it useful for drilling holes and driving screws with control. Most drills have a low and high speed range; low is for torque and careful fastening, while high is for drilling smaller holes quickly.
An impact driver has a quick-change hex collet, usually sized for 1/4-inch hex bits. As resistance rises, an internal mechanism delivers short rotational blows. Those impacts help drive a fastener without requiring you to lean as hard on the tool. They also make the tool loud and can make it harder to stop precisely at a screw’s intended depth.
Quick comparison
| Task or feature | Cordless drill | Impact driver |
|---|---|---|
| Driving a few cabinet or furniture screws | Controlled and quiet; clutch helps prevent damage | Works, but can be unnecessarily forceful |
| Driving many long screws | Can work hard and twist your wrist as resistance climbs | Usually faster, with less reaction torque at the handle |
| Drilling holes with common round-shank bits | Best choice; its chuck accepts a wide range of bits | Limited to compatible hex-shank accessories |
| Precision and noise | Generally quieter and easier to control | Louder; impacts can overdrive or damage a fastener |
| Buying one tool | More versatile for everyday home tasks | Best when fastening is the main job |
For drilling, choose the drill
A drill’s three-jaw chuck can hold round-shank twist bits, spade bits, hole saw arbors, and many other accessories. That makes it the straightforward choice for pilot holes, furniture assembly, and holes for wall anchors. A 3/8-inch chuck handles many household bits; a 1/2-inch chuck accepts larger shanks and is useful for heavier work.
Impact drivers can drill with hex-shank bits, but the selection is narrower, and the repeated blows are not ideal for every bit or material. Use a drill for clean holes in wood, metal, and plastic. For masonry, use a hammer drill with the correct masonry bit when the wall material calls for it; neither a standard drill nor an impact driver is a replacement for a rotary hammer on substantial concrete work.
Match the bit to the job. For a wall anchor, follow the anchor package’s stated hole diameter rather than guessing. A hole that is too large may let the anchor spin or pull out; one that is too small can crush or deform it during installation. Keep the drill straight, clear dust from the hole, and avoid drilling where wiring or plumbing may run.
For screws, consider volume and control
For a handful of short screws in furniture or a hinge, a drill is usually easier to control. Set its clutch low and increase the setting only if the fastener stops before it seats. The clutch reduces the chance of stripping the screw head, snapping a small screw, or burying the head below the surface. It is not a guarantee: start slowly and stop when the screw is seated.
For repeated fastening—deck screws, framing connectors, or a run of cabinet screws—an impact driver can be more comfortable and efficient. It tends to keep turning as resistance rises, while a drill may stall or twist your wrist. Use a quality impact-rated bit, keep it aligned with the screw, and ease off near the end. Too much force can strip the drive recess, split wood near an edge, or drive a fastener too deep.
Impact drivers are also louder than drills. Wear hearing protection during sustained use, and don’t assume a higher torque rating means better results. For delicate hardware, a slow drill with a clutch—or a hand screwdriver—may be the safer option.
What to buy
If you need one tool for holes, anchors, and occasional screws, buy a cordless drill-driver kit. A basic 12-volt model is often enough for furniture, small pilot holes, and light repairs. Choose an 18- or 20-volt platform if you expect larger bits, longer screws, or regular work; those labels describe the same nominal battery class, not a direct measure of useful runtime or power.
If you already own a compatible drill and often drive long fasteners, a cordless impact driver is a sensible addition. Battery-platform compatibility can save money, but check that the kit includes the battery and charger you need. For occasional home use, there is no need to buy both just because they are commonly sold as a set.
Avoid common fastening mistakes
Choose the correct driver bit and replace worn bits; a loose fit cams out more easily and damages screw heads. Make a pilot hole in hardwood or near the end of a board when the fastener or material risks splitting. For a wall anchor, drill the specified diameter and use a screw that suits that anchor—an oversized screw can prevent proper expansion.
On either tool, start with the bit square to the fastener and use a light trigger pull. If the bit slips, stop and reseat it rather than pushing harder. When drilling into a wall, check for hidden services first. If a screw keeps spinning without tightening, the hole or substrate may be damaged; switching to an impact driver will not fix a failed anchor or stripped wood.
