DEWALT DCK277D2 Drill and Impact Driver Combo Kit Review

The DEWALT DCK277D2 in one breath

If you want a brushless cordless drill and a brushless impact driver in a single box, with two batteries and a charger so you can actually start working the day it arrives, the DEWALT DCK277D2 drill and impact driver combo kit is one of the most common answers you'll see at a hardware-store endcap. It pairs the DCD777 drill/driver with the DCF787 impact driver, both running brushless motors, and ships with two 2.0Ah batteries, a charger, and a contractor bag. DEWALT lists exactly that bundle on the official DCK277D2 product page.

It is a genuinely capable homeowner-to-light-trade kit. It is also a kit that sits next to a newer, very similar DEWALT bundle, which is the single most important thing to understand before you buy. We'll get to that.

The DCK277D2 pairs the DCD777 drill/driver and DCF787 impact driver with two 2.0Ah batteries.

How we evaluated this kit

A quick note on method, because it changes how you should read everything below. We did not run this kit through a hands-on bench test. This review is research-based: we cross-checked DEWALT's published specifications against independent retailer spec sheets and editorial tool coverage, compared the kit against its closest in-family sibling, and weighed the price against what the same money buys elsewhere. Where a number appears, it is anchored to the manufacturer's spec sheet or a reputable third-party source and linked inline. Where buyers commonly run into trouble, we point to documented, verifiable issues rather than anecdote. That honesty is the point: you can click every claim and check it yourself.

DEWALT DCK277D2 specifications: what's actually in the box

The DCK277D2 is the brushless version of DEWALT's long-running compact 2-tool combo. Here's what each tool brings, with the numbers pulled from DEWALT and authorized retailers.

The DCD777 drill/driver is a 1/2-inch brushless compact drill. It puts out 340 unit watts out (UWO), runs a two-speed transmission with no-load speeds of 0–500 and 0–1,600 RPM, and uses a 1/2-inch ratcheting chuck with 15 clutch settings, per the DEWALT DCD777B product page and a retailer spec breakdown at ToolUp. It weighs around 2.6 lbs bare and is short front-to-back, which is the real selling point of a compact drill: it gets into cabinets and joist bays a full-size hammer drill can't.

The DCF787 impact driver is a 1/4-inch hex brushless impact. DEWALT's own support documentation rates it at 1,500 in-lbs of max torque, 0–2,800 RPM, and 0–3,200 impacts per minute (IPM), as stated in DEWALT's DCF787 specs support article. It's the tool you reach for to drive long deck screws or lag bolts without stripping out your wrist or the fastener.

What is the difference between DCK227D2 and DCK277D2?

This is the question to answer before you spend a dollar, because the two kits look almost identical on a shelf and are priced within striking distance of each other.

The difference is the tools inside. The DCK277D2 pairs the older DCD777 drill and DCF787 impact. The DCK227D2 pairs the newer DCD793 drill and DCF840 impact. The DCK227D2's impact driver steps up to 1,700 in-lbs of torque versus the DCK277D2's 1,500 in-lbs, and DEWALT positions its drill as the stronger of the two, all per DEWALT's official DCK227D2 product page. Both kits ship the same support package: two 2.0Ah batteries, a charger, and a bag.

So the honest framing is this. The DCK277D2 is the proven, slightly older generation. The DCK227D2 is the newer generation with a meaningfully stronger impact. Tool-industry coverage has been blunt about the implication: when the two kits are priced the same, the newer DCK227D2 is the better value, and the DCK277D2 only makes sense when it's clearly cheaper. ToolGuyd's comparison of DEWALT's combo-kit deals lays out exactly that reasoning. The DCK277D2 is a buy when it's on sale, not at parity.

That matters here, because the deal that prompted this review is a discounted DCK277D2 (39% off at the time of writing), which is precisely the scenario where this kit becomes the smart pick rather than the also-ran. Price-checking the live discount against a same-price DCK227D2 is the single best thing you can do before checkout.

How it compares to the older DCK240C2

A lot of shoppers land here after looking at the brushed DCK240C2 (the DCD771 drill plus DCF885 impact). The jump from the DCK240C2 to the DCK277D2 is the jump from brushed to brushless motors. Brushless motors run cooler, last longer, and squeeze more work out of the same battery: DEWALT cites up to 57% more runtime for the brushless DCF787 over a comparable brushed impact in its DCF787 kit listing. If you're choosing between the brushed DCK240C2 and the brushless DCK277D2 at similar prices, the brushless kit is the longer-term buy.

Which DeWalt combo kit is best?

There isn't one universal "best." The right kit depends on what you're doing with it, so here's the practical sorting.

• Most homeowners and DIYers: the DCK277D2 (this kit) or the DCK227D2 are both more drill and impact than you'll ever need for furniture, decks, fence repair, and hanging things. Buy whichever is cheaper at the moment, with a slight edge to the DCK227D2 for its stronger impact if the prices are close.
• Light-trade and remodelers who'll drive a lot of long fasteners: lean toward the DCK227D2 for that extra 200 in-lbs of impact torque, or step up to DEWALT's XR-tier kits if you're on the tools daily.
• Compact-access work (cabinet installs, electrical, tight framing): the DCD777's short head length is a real advantage, and the DCK277D2 shines here.

The reason a combo kit makes sense at all is that a drill and an impact driver do different jobs. A drill bores holes and drives fasteners with clutch-controlled precision; an impact driver hammers high-torque fasteners home without cam-out. If you're unsure why you'd want both, our explainer on the difference between a drill driver and an impact driver walks through it with examples. And if you're cross-shopping the whole category, our guide to the best cordless drills and driver kits for 2026 ranks this kit against its main rivals.

What are the common problems with DeWalt impact drills (and this kit)?

A balanced review names the weak spots. For this kit, the documented soft spot isn't the impact driver, it's the drill's chuck.

The DCD777 uses a single-sleeve ratcheting chuck, and a recurring owner complaint is that it can lose grip on bits over time or fail to clamp down hard enough when tightened one-handed under power. It's worth knowing that DEWALT classifies drill chucks as a wearing part rather than a defect covered indefinitely under warranty, so a worn chuck is treated as a service item. The practical workaround is mundane but effective: tighten the chuck with the trigger released and give it a firm final twist by hand rather than spinning it shut. None of this makes the drill a bad tool, but it's the most consistent friction point and you should buy with eyes open.

On the impact-driver side, the DCF787 is well regarded for its size and output. The honest caveat is generational rather than mechanical: at 1,500 in-lbs it trails newer DEWALT impacts (the DCF840 in the DCK227D2 hits 1,700 in-lbs), so if you anticipate a steady diet of large lags, the newer unit has headroom this one doesn't, per DEWALT's DCK227D2 specs.

The DCF787 impact driver is rated at 1,500 in-lbs of torque for driving long fasteners and lags.

Is DeWalt or Milwaukee higher quality?

It's the inevitable next question, and the honest answer is that both are top-tier professional brands and the "winner" depends on the specific tool, not the badge. In a head-to-head of their flagship hammer drills, Pro Tool Reviews found the two were closely matched on speed and power, with the editor ultimately favoring Milwaukee's M18 Fuel for being lighter and more compact, while acknowledging DEWALT's strong value in two-battery kits.

That last point is exactly where the DCK277D2 lives: it's a value-priced, two-battery brushless kit on a battery platform shared across hundreds of DEWALT tools. If you already own DEWALT 20V MAX batteries, the calculus tilts hard toward staying in the family. If you're starting from zero, both ecosystems are excellent, and the deciding factors are usually the price on the specific kit in front of you and which battery platform your friends and jobsite already use. Don't agonize over the brand war; buy the better deal on a kit that fits your work.

Verdict: a smart buy when it's on sale

The DEWALT DCK277D2 is a dependable brushless drill-and-impact pairing that does almost everything a homeowner or light-trade user needs, on a battery platform that won't strand you. Its honest weaknesses are a generationally older impact (1,500 vs. 1,700 in-lbs on the newer DCK227D2) and a chuck that some owners find finicky over time. Because the newer DCK227D2 exists at a similar price, the buying rule is simple: get the DCK277D2 when it's discounted, and skip it when it's priced level with the DCK227D2. With the current 39% markdown, this is the right side of that line.
