For most cabinet assembly, a cordless drill is the better first tool. It gives you control over screw depth and can drill clean pilot holes without pounding the fastener. An impact driver is useful for driving long screws or assembling cabinets from thick, dense material, but its hammering action can split a panel, strip a screw head, or pull a fastener too deep if you’re not careful.

What we cover
The quick answer
Choose a cordless drill if you’re assembling flat-pack cabinets, installing hinges, drilling shelf-pin holes, or doing a mix of drilling and fastening. Its adjustable clutch makes it easier to stop screws at a consistent depth.
Choose an impact driver if you regularly drive long construction screws, work with hardwood or dense materials, or already own a drill for holes and delicate work. For a single cabinet project, buying an impact driver instead of a drill is usually the wrong trade: it’s excellent at driving, but less forgiving on small cabinet screws.
Drill vs. impact driver for cabinet work
| Task or feature | Cordless drill | Impact driver |
|---|---|---|
| Driving cabinet assembly screws | Better control; clutch helps prevent overdriving | Fast, but easier to strip or bury screws |
| Drilling pilot holes | Designed for this; accepts standard drill bits | Possible with a hex-shank bit, but less suited to precise drilling |
| Long screws in dense material | Can stall or strain on tougher jobs | Usually drives them with less effort |
| Small screws and hinges | More forgiving at low speed and low clutch settings | High risk of damaging screw heads or cabinet material |
| Bit compatibility | Typically takes round or hex shanks in a three-jaw chuck | Usually takes 1/4-inch hex-shank bits |
Why a drill is the safer cabinet tool
A drill turns steadily, and its clutch slips when resistance reaches the setting you choose. That makes it easier to seat a screw without crushing a particleboard panel or pulling its head through a hinge. Start with a low clutch setting, test on scrap or an inconspicuous spot, then increase it only if the screw stops short.
For many flat-pack cabinets, the included screws are short and intended for predrilled holes. Use the bit specified in the instructions, keep the driver aligned with the screw, and finish by hand if you need precise final tightness. A basic cordless drill-driver kit is enough for this work; you don’t need a premium model just to assemble a few cabinets.
A drill also handles the other jobs that tend to arise during installation: boring pilot holes, drilling through a cabinet back, or making holes for hardware. Use a sharp bit and the correct diameter. A pilot hole that’s too small can split solid wood; one that’s too large gives the screw threads little material to grip. In particleboard, follow the cabinet maker’s instructions rather than assuming a deeper or wider pilot hole is better.
When an impact driver earns its place
An impact driver applies rotational blows as resistance rises. That helps it keep turning long screws into dense wood, where a drill might slow down or stall. It can be a good choice for repeated installation work, cabinet cleats, or other structural fastening—not usually for the small screws holding hinges and drawer slides.
The trade-off is control. Impact drivers generally don’t have the same adjustable clutch behavior as a drill, and the repeated impacts can damage soft materials. A screw that suddenly breaks through a panel may sink below the surface; a bit that cams out can chew up the screw head. If you use one, choose a low-speed setting if available, apply steady pressure, and stop before the screw is fully seated. Finish gently by hand or with a drill set to a low clutch setting.
If you already own a drill and frequently drive long fasteners, an impact driver kit can complement it. If cabinet assembly is an occasional job, the added tool and battery cost may not pay off.
How to avoid stripped screws and split panels
Match the driver bit to the screw head. A bit that is even slightly loose can slip under load, especially with an impact driver. Keep the tool straight and push firmly into the fastener; if the bit keeps climbing out, stop rather than forcing it.
Don’t use maximum speed for every screw. Start slowly, especially near the edge of a panel or when fastening a hinge. Driving too close to an edge can split solid wood, while over-tightening a screw in particleboard can strip the hole so the screw no longer holds. If a screw spins without tightening, stop. A longer or larger screw is not automatically a safe fix: it can break through a thin panel or interfere with adjacent hardware.
For installation screws going through a cabinet rail into a wall stud, first drill a pilot hole sized for the screw’s shank and use the appropriate screw for the framing. A cabinet’s own assembly screws are not substitutes for wall fasteners. For masonry, use a suitable masonry bit and anchor or fastening system rather than driving an ordinary wood screw into the wall.
What to buy for one cabinet project
If you own no tools, buy a drill-driver with a variable-speed trigger, a clutch, and a battery platform you can use for future tools. A 12-volt drill is often compact enough for cabinet interiors and has plenty of power for ordinary assembly. An 18- or 20-volt drill is a sensible choice if you also expect to drill larger holes or handle general home repairs. Battery voltage alone doesn’t guarantee better control or performance.
Buy a small set of quality driver bits and the drill bits required by the cabinet instructions. A magnetic bit holder can make overhead or awkward fastening easier. Don’t buy an impact driver solely because its torque number is higher: cabinet work rewards accurate, repeatable fastening more than raw force.
Which should you use?
Use a cordless drill for flat-pack assembly, hinge screws, pilot holes, and most cabinet installation adjustments. Use an impact driver when the job includes many long screws or dense-material fastening, and keep the drill available for holes and delicate screws. For occasional cabinet assembly, the cheaper option—a basic drill-driver—is fine and usually the more useful purchase.
