Choosing a Cordless Drill
A cordless drill is the tool you will use most and the one most worth spending on. The differences between a $90 and a $250 drill are real, and they are not marketing.
Voltage
| Platform | Torque class | Best for |
|---|---|---|
| 12V | Light | Cabinet hardware, assembly, occasional work |
| 18V / 20V | General | The right answer for almost everyone |
| 36V / 40V | Heavy | Structural screws, big bits, masonry |
18V/20V is the standard platform with the widest range of tools and the best battery availability. Going higher adds weight for work most woodworkers do not do.
Brushless matters
A brushless motor has no friction brushes wearing out. It runs cooler, lasts far longer, and is more efficient, which translates to more work per charge. On a tool you use daily, the price difference pays back.
Brushed motors are still fine for occasional use and for budget tools. They are not wrong, they are just consumable.
Drill versus driver
This distinction matters more than most people expect:
- Drill/driver — adjustable clutch. Use the clutch for screws so you do not strip them and overdrive the tip. Use the drill mode for boring holes.
- Impact driver — a high-torque driver that hammers as it turns. It is dramatically better for long structural screws and deck screws. It is not a drill and will break standard bits.
- Driver only — fixed clutch, light duty. Fine for furniture assembly.
Using a drill for structural deck screws is the most common reason screws strip or snap. An impact driver solves it. If you build decks, this is not an optional upgrade.
Battery platform is the real decision
Buy into a platform, not a tool. Batteries are the expensive part of ownership, and platforms are not cross-compatible across brands. A manufacturer with a good tool but a weak battery ecosystem is a poor choice if you will eventually buy a saw, a sander and an impact driver.
Buy two batteries minimum. Single-battery tools mean waiting for a charge at the worst moment.
Chuck size
½ inch is the standard and accepts everything up to 1 inch bits. A ⅜ inch chuck on a lighter drill is fine for smaller bits and pilot holes, but it limits what you can use later. The keyless chuck is better than a keyed one if you work with one hand.
For woodworking specifically
- Brushless, 18V or 20V
- ½ inch metal or metal-and-plastic chuck
- At least 2 speed settings — low speed for driving, high for boring
- A clutch with enough positions to dial in small screws
- Good balance — a drill you can hold one-handed for an hour matters on a build

Specific models worth comparing
Everything below sits on the same 20V MAX battery platform, which is the practical reason to start there: one set of batteries then covers the drill, the impact driver and any bare tool you add later.
- DEWALT 20V MAX XR Drill/Driver Kit (DCD771C2) — the single-tool starting point. Two speed ranges, a 1/2 inch chuck, and enough torque for pilot holes and driving 3 inch screws into softwood. Buy this if you only need one drill.
- DEWALT 20V MAX Drill and Impact Driver Combo (DCK240C2) — the same class of drill plus an impact driver, which is what actually drives long screws without stripping heads or camming out. The better buy for furniture and deck work.
- DEWALT 20V MAX 5Ah Battery 2-Pack with Charger — worth adding if you run two tools at once. The compact packs that ship in kits empty out halfway through a project.
- DEWALT Black Oxide Drill Bit Set, 20-Piece — brad-point bits matter more than the drill for clean holes in wood. A general-purpose set wanders on the entry face.
None of these is the cheapest thing in the aisle. What you are paying for is the platform: batteries, chargers and bare tools stay available for years, which is not true of house-brand cordless lines that change every season.
