I’ll be straightforward about something upfront: there’s no single “best” Dewalt 20V combo kit, because the right one depends entirely on which tools you’ll actually use weekly versus which ones will sit in the case. I’ve put together enough of these kits for myself and for other people’s garages to know where the money gets wasted.
Why buy a combo kit instead of separate tools
The math on combo kits almost always favors buying the kit, even if you only want two of the five tools inside. Dewalt prices a drill/driver and impact driver combo with two batteries, a charger, and a bag at roughly what you’d pay for one bare tool plus a battery separately. The batteries are the expensive part, not the tool heads. A 20V Max 5Ah battery runs $90-120 on its own, so a kit that throws in two batteries for not much more than the price of one bare tool is where the actual savings live.
The trade-off is that bigger kits (5-6 tools) often include things you won’t use much, like a reciprocating saw or a flashlight, and the per-tool cost creeps up because you’re paying for bulk convenience. If you only need a drill and impact driver, a 2-tool kit is almost always the better value than a 5-tool kit you raid for two things.
The real reason to commit to Dewalt 20V Max
Dewalt’s 20V Max line has been around long enough that it’s the deepest cordless ecosystem on the market after Milwaukee’s M18. That matters more than any single tool’s spec sheet. Once you own two or three 20V Max batteries, every new tool you buy as “bare tool only” instead of a full kit, which is where the real savings start compounding over years. I’ve got batteries from a 2017 kit still running a current-generation impact driver with no issues.
The catch: 20V Max batteries come in two body styles, the compact and the larger XR, and while they’re cross-compatible, a compact 1.5Ah battery on a reciprocating saw or a big circular saw will bog down fast under load. If your kit comes with small batteries, budget for at least one 4Ah or 5Ah battery for anything that draws real current.
Matching the kit to the work
For general DIY, furniture assembly, deck boards, and the occasional shelf, a drill/driver plus impact driver combo covers 90% of jobs. The drill handles drilling and driving where control matters; the impact driver handles lag bolts, deck screws, and anything where you want torque without stripping your wrist. If that’s your use case, look at a Dewalt 20V drill and impact driver combo kit and stop there. Don’t let a bigger kit talk you into tools you don’t need yet.
If you’re doing framing, trim work, or regular home renovation, a circular saw and a reciprocating saw earn their keep. The cordless circular saw is genuinely good for sheet goods and quick crosscuts, though if you’re ripping a lot of plywood all day, a corded saw or table saw will beat it on heat management and battery life. For demo work, a Dewalt 20V combo kit with a circular saw and reciprocating saw is worth the step up.
If you want one kit to cover almost everything, including an oscillating tool or a jigsaw for odd cuts, the larger 5-6 tool kits exist for that, but check the included battery sizes before buying. Some of these bundle two compact batteries, which is fine for drills but weak for saws.
How the common kit sizes stack up
| Kit size | Typical price range | Best for | Watch out for |
|---|---|---|---|
| 2-tool (drill + impact driver) | $150-200 | General DIY, assembly, repairs | No saw included; fine if you already own one |
| 3-4 tool | $250-350 | Renovation, deck building, trim work | Check which saw type is included, circular vs. reciprocating |
| 5-6 tool | $400-550 | Full workshop setup, first-time buyers | Compact batteries may underpower the saws |
Brushless motors are worth paying for now
A few years ago brushless was a premium feature that pushed kit prices up noticeably. That gap has closed. Most current Dewalt 20V Max kits in the mid-range and above use brushless motors, and the difference is real: less heat, longer runtime per charge, and the motor doesn’t wear out brushes over years of use. If you find a brushed kit priced close to a brushless one, there’s no reason to take the brushed version unless it’s genuinely $50+ cheaper and you’re an occasional user.
What actually breaks on these kits
In my experience, the batteries are the wear item, not the tools. A 20V Max battery that sees daily jobsite use will noticeably lose capacity after 2-3 years; one that sees weekend DIY use can last 7-8 years. The tools themselves are durable at the gear and motor level, but chucks on drills can get sloppy if you cross-thread bits repeatedly, and the plastic battery latch on older designs can crack if the tool gets dropped onto concrete battery-first. None of this is a reason to avoid the platform, it’s just what to expect and budget for.
What I’d actually buy
If you’re starting from zero and don’t own any cordless tools, the 2-tool drill/impact driver kit is the right first purchase for most people, not the biggest bundle on the shelf. Add tools as bare units when a specific job needs them. That’s cheaper over three years than buying a 6-tool kit upfront and letting half of it sit in the case.
