A cordless drill/driver is a rechargeable-battery tool that both drills holes and drives screws, replacing the cord with a removable battery pack.
A cordless drill/driver combines drilling and screwdriving in a single handheld tool, powered by a rechargeable battery instead of a wall outlet. This is the tool most homeowners reach for first when hanging shelves, assembling furniture, or making pilot holes, and it earns its keep because one compact body handles two jobs without an extension cord.
What Exactly Does a Drill/Driver Do?
A drill/driver drills holes and drives screws. You fit a twist drill bit to make holes and swap in a screwdriver bit to sink fasteners, all from the same chuck. This dual role is what separates it from a dedicated drill, which only makes holes.
Bosch Professional describes its cordless drills/drivers specifically as tools for both drilling and screwdriving. The same principle holds across every major brand: one motor, one chuck, two functions.
Key Specs That Define the Tool
Manufacturers specify drill/drivers by a handful of numbers that tell you what the tool can handle.
- Battery voltage – Current models range from 12V compact units up to 18V full-size tools. Higher voltage generally means more power for tougher materials.
- Chuck size – Most drill/drivers use a 10 mm or 13 mm keyless chuck, which determines the maximum bit shank size the tool accepts.
- No-load speed – Multi-speed gear ranges like 0–400 rpm and 0–1400 rpm let you shift between high-torque slow driving and faster drilling.
- Max torque – This varies widely by model, from entry-level figures near 20 Nm up to 84, 100, or even 150 Nm on professional tools.
The range is wide because the tool class is wide. HiKOKI, for example, offers compact 10.8–12V models for light duty alongside 18V units rated for sustained professional work.
Drill/Driver vs. Hammer Drill vs. Impact Driver
A plain drill/driver is not a hammer drill or an impact driver, and confusing them leads to wrong purchases. A hammer drill adds a pounding action for masonry. An impact driver delivers rapid rotary concussions for stubborn long screws. A drill/driver does neither—it simply spins, which is exactly right for everyday wood, metal, and plastic work.
If you mostly drive deck screws or drill through studs, a drill/driver handles it. If you plan to drill into concrete or drive lag bolts all day, buy the specialized tool instead.
Compatibility and Safety Gotchas
Treating all cordless drill/drivers as interchangeable is a mistake. Battery voltage, battery chemistry, chargers, and included accessories vary by model and by country, so a pack from one brand rarely fits another, and even regional versions of the same brand differ. Before buying a second battery, check that it matches your exact model and area.
Official manuals also carry safety requirements worth honoring. If you are ready to compare specific models side by side, our tested roundup of the best cordless drill drivers walks through the top picks.

FAQs
Can a Drill/Driver Replace an Impact Driver?
Not entirely. A drill/driver spins at a steady speed, which is ideal for holes and light screwdriving. An impact driver adds concussive force that drives long or stubborn screws faster and with less wrist strain, but it lacks the precision a drill chuck offers for clean holes. Serious DIYers own both.
What Volt Drill Do I Need for Home Use?
For most household tasks—furniture assembly, curtain rods, basic shelf work—a 12V compact model provides plenty of torque and weighs noticeably less. If you regularly drill into hardwood, use hole saws, or drive larger screws, step up to an 18V tool, which handles sustained loads without bogging down.
What Does a Keyless Chuck Mean?
A keyless chuck lets you tighten or loosen the bit by hand instead of using a separate chuck key. You twist the collar to grip the bit securely, and it works with both round drill bits and hex screwdriver bits. It is the standard on nearly all modern cordless drill/drivers.
