A drill is the more versatile first tool for holes and controlled fastening; an impact driver is faster for repeated screws and larger fasteners, with less finesse. Drills use a chuck for round-shank bits, while most impact drivers use a quick-change hex collet. Buy a drill first for mixed tasks, then add an impact driver when fastening volume or stubborn screws is slowing the work.
For a first cordless tool, the drill covers more kinds of work. The impact driver earns its place when a crew drives fasteners all day.
What each tool does best
| Tool | Best fit | Main tradeoff |
|---|---|---|
| Drill/driver | Holes, pilot holes, mixed materials and controlled fastening | Slower on repeated large screws |
| Impact driver | Decking, structural screws and repetitive fastening | More noise and less delicate clutch control |
| Hammer drill | Masonry holes when the model has a hammer mode | Bulkier than a compact drill for everyday work |
An impact driver’s blows turn the fastener; a hammer drill’s blows travel along the bit. They solve different problems. An impact driver does not replace a rotary hammer for heavy concrete drilling.
Match the tool to the fastener
Most drills use a three-jaw chuck that accepts round-shank bits. Most impact drivers use a quick-change hex collet, so check the bit shank before buying accessories. Hex-shank drill bits work in many drivers, but the tool’s control and the bit’s rating still matter.
Use a drill clutch for small screws, softwood, cabinetry and repeated assembly. Start with a pilot hole when the material or fastener calls for it. Use an impact driver for long screws or repetitive fastening when a drill stalls or heats up. Follow the tool and fastener manufacturers’ instructions.
Choose the first tool by the work week
For punch-list work and a broad starter kit, buy a drill/driver. For framing, decking or installation crews that already own a drill, an impact driver saves time on repeat fastening. Compare the battery platform, grip, balance, variable-speed trigger, work light and service support across the tools you will use most.
OSHA’s construction power-tool rules cover electric and pneumatic tools; use guards, bits and operating methods specified by the tool maker. Read OSHA’s construction power-operated hand-tool requirements.

Common questions
Can an impact driver drill holes?
Yes, with a compatible hex-shank bit. A drill accepts a broader range of round-shank bits and gives finer speed and clutch control.
Is an impact driver the same as a hammer drill?
No. An impact driver adds rotational impacts for driving fasteners. A hammer drill adds axial percussion for masonry drilling.
Which should I buy first?
Choose a drill for furniture, pilot holes, general maintenance and mixed materials. Choose an impact driver first only when fastening is the clear main job.
Will an impact driver strip screws?
It can. Use the correct bit, low speed where available, steady pressure and a clutch-controlled drill when the material or fastener needs delicate control.
