A DeWalt 20V MAX cordless drill combo kit pairs a 1/2-inch drill/driver with a 1/4-inch hex impact driver, two batteries, a charger and a bag, and the main decision is which motor tier you buy: the brushed kit built around the DCD771 drill and DCF885 impact is the cheapest way into the platform, the compact brushless kits trade a modest price bump for longer runtime and a smaller head, and the XR brushless kits add real power and better batteries for people who drill large holes or drive long screws often. Because every kit uses the same 20V MAX battery, whichever you choose becomes the entry point to hundreds of other DeWalt tools.

What we cover
Brushed vs Brushless vs XR: What Changes
A brushed motor uses carbon brushes to switch current; a brushless motor does it electronically. Brushless designs waste less energy as heat and friction, so the same battery lasts longer and the tool can be shorter and lighter for the same output. DeWalt’s XR label marks its higher-performance brushless tier, usually with three-speed or high-torque settings on the impact driver and larger batteries in the kit.
| Tier | Example drill / impact | Drill max speed | Impact torque | Batteries usually included | Typical kit price range |
|---|---|---|---|---|---|
| Brushed entry | DCD771 / DCF885 | 0–450 / 0–1,500 rpm | About 1,400 in-lbs | Two compact 1.3–2.0Ah | $130–$200 |
| Compact brushless | DCD777 / DCF787 | 0–450 / 0–1,750 rpm | About 1,500 in-lbs | Two compact 1.3–2.0Ah | $150–$230 |
| Atomic (ultra-compact brushless) | DCD708 / DCF809 | Roughly 1,650 rpm high gear | Roughly 1,500 in-lbs class | Two compact 1.3–2.0Ah | $150–$230 |
| XR brushless | DCD791 / DCF887 (or newer XR successors) | 0–550 / 0–2,000 rpm | About 1,825 in-lbs | 2.0Ah compact or 4.0–5.0Ah | $230–$380 |
Kit bundles, battery sizes and model numbers change with promotions and product refreshes, so read the box for exactly which drill, impact and battery capacity are inside. Two kits that look alike in photos can differ significantly in battery size.
Which Kit Fits Your Work
| Your work | Best tier | Reason |
|---|---|---|
| Furniture assembly, hanging shelves and TVs, occasional repairs | Brushed entry | Plenty of power for small fasteners; lowest cost into the platform |
| Regular DIY, small deck repairs, overhead work, cabinets | Compact brushless or Atomic | Lighter and shorter for tight spaces; better runtime per charge |
| Deck building, framing, long lag screws, large spade and auger bits | XR brushless with 4–5Ah batteries | Higher torque and sustained power without bogging down |
| Masonry anchors in brick or block | Look for a hammer-drill version in any tier | Plain drill/drivers struggle in masonry |
| Already own 20V MAX batteries | Consider bare tools instead of a kit | Kits mainly add value through batteries and charger |
The Batteries Decide How the Kit Feels
Most entry and compact kits ship with small 1.3 to 2.0Ah packs. They keep the drill light, which is great for overhead work, but they run down quickly under heavy load and deliver less peak current than larger packs, so the drill can feel weaker when boring big holes. A 4.0 or 5.0Ah XR battery adds weight but gives longer runtime and slightly stronger performance in demanding tasks.
A practical approach is to buy the kit tier that fits your tools, then add one larger battery later when you find yourself waiting on the charger. The basic chargers included with entry kits are also slow, often taking roughly an hour or more to fill a 2Ah pack; a faster charger is a worthwhile upgrade if you work in long sessions.
Drill vs Impact Driver: Use Each for the Right Job
- Drill/driver for drilling holes, mixing small batches with a paddle, driving screws where you need the clutch to stop at a set depth, and delicate fasteners in hardware or soft materials.
- Impact driver for long screws, lag bolts, deck screws and repetitive fastening. Its hammering action drives with less wrist strain and less cam-out, but it has no clutch and can snap small screws or strip soft wood.
- Bits matter. Use impact-rated driver bits in the impact; standard bits can shatter. Hex-shank drill bits also fit the impact for light drilling.
Ownership Realities: What Wears First
Chuck
The single-sleeve ratcheting chuck on DeWalt drill/drivers is convenient, but it is the part that most commonly develops slip with heavy use. Tighten firmly until the ratchet clicks stop, and avoid gripping bits by the coated tips. Clean dust out of the jaws occasionally.
Brushes on brushed models
Brushed drills eventually wear down their carbon brushes. For the typical homeowner that takes years, but it is a real end-of-life point that brushless motors do not have.
Batteries
Lithium-ion packs lose capacity over hundreds of cycles and faster if left hot or fully empty. Store them in a cool place and avoid leaving them in a vehicle in summer or freezing temperatures. A battery that suddenly runs only a few minutes is usually at end of life, not a sign the tool has failed.
Clutch and gearbox
Using the drill in the drill setting to drive large lag screws stresses the gearbox. Let the impact driver do heavy fastening, and use the low gear on the drill for large bits.
Common mistakes
- Running large spade or hole-saw bits in high gear, which stalls the motor and overheats both tool and battery.
- Using the impact driver with non-impact bits.
- Leaving the clutch on a high number when driving small screws into soft wood.
- Charging hot batteries straight after heavy use; let them cool first so the charger can do its job.
Warranty and Platform Value
DeWalt typically backs its 20V MAX tools with a limited warranty measured in years, along with a shorter free-service period, and batteries carry their own coverage; confirm the terms on the specific kit’s documentation. The larger value is the platform: the same battery runs circular saws, oscillating tools, lights, vacuums, outdoor equipment and more, and DeWalt FLEXVOLT batteries also fit 20V MAX tools if you later want larger packs. Choosing a combo kit is really choosing an ecosystem, so pick the tier that matches the work you expect over the next several years rather than the cheapest box today.
Quick Recommendation
- Tight budget, light home use: the brushed DCD771/DCF885 kit.
- Most homeowners and serious DIYers: a compact brushless or Atomic kit, plus one 4Ah battery later.
- Heavy projects and frequent use: an XR brushless kit with 4–5Ah batteries.
