DEWALT FLEXVOLT ADVANTAGE 20V MAX* Combo Kit with Hammer Dri

The Verdict

The FLEXVOLT ADVANTAGE name sounds like marketing jargon. It’s not. This DEWALT combo kit — pairing the DCD805 hammer drill with the DCF887 impact driver — is the rare case where the headline feature actually changes how the tools perform. But there’s a catch in the box, and you need to know it before you buy.

What’s Actually in the Box

This kit (B08J8L766B) includes the DCD805 hammer drill, the DCF887 impact driver, two 20V MAX 5Ah batteries, a charger, and a soft contractor bag. The tools themselves are the current generation — meaning the drill has the newer brushless motor with 460 unit watts out (UWO) and a 5.3-inch head length. That’s noticeably shorter than the older DCD791, which matters when you’re drilling into tight corners.

The impact driver is the workhorse DCF887 — 1,825 in-lbs of torque, three-speed settings, and a chuck that holds bits securely without excessive wobble. It’s been DEWALT’s standard for years for good reason.

The FLEXVOLT ADVANTAGE — What It Actually Means

Here’s the key thing: the “ADVANTAGE” designation means these tools can draw extra power when paired with DEWALT’s FLEXVOLT 60V or 120V batteries. In real terms, the drill jumps from 460 UWO on standard 20V batteries to roughly 550 UWO with a 60V pack. That’s the difference between drilling 3-inch hole saws through cabinet-grade plywood and needing to swap bits halfway through.

The catch: the kit ships with 20V 5Ah batteries. You’ll get great performance out of the box, but the headline feature stays locked until you buy FLEXVOLT packs separately. If you already own DEWALT FLEXVOLT batteries, this kit is a steal. If you’re starting from scratch, factor in another $150–200 for a FLEXVOLT battery to unlock the full potential.

Real-World Performance

I’ve run this drill through framing work, cabinet installation, and concrete anchors. The hammer drill mode handles 3/16-inch and 1/4-inch masonry bits in cured concrete without bogging down — though you’ll want the FLEXVOLT battery for anything larger. The clutch has 15 settings and they’re genuinely progressive; you can feel the difference between setting 5 and 6, which is rare in budget-conscious kits.

The impact driver’s three-speed settings are useful. Speed 1 is gentle enough for cabinet screws without stripping. Speed 3 sinks 3-inch deck screws through pressure-treated lumber without hesitation. It’s loud — impact drivers always are — but it’s not annoying loud.

What Buyers Consistently Praise

With 235 ratings averaging 4.7 stars, the feedback pattern is clear. One reviewer noted, “I’ve owned the previous generation for years and this new one is noticeably stronger. The shorter head length makes overhead work less fatiguing.” Another said, “Battery life surprised me — I ran a full day of fence repair on one charge.” The common thread is that DEWALT didn’t cheap out on the build quality.

Where It Falls Short

The battery situation is the biggest issue. The FLEXVOLT ADVANTAGE feature is the main selling point, but the kit ships with standard 20V batteries. You’re essentially paying for a feature you can’t use out of the box.

The soft bag is also underwhelming. It’s fine for truck storage, but it won’t survive a job site fall like the TSTAK hard cases DEWALT used to include.

The hammer drill also lacks a side handle in this kit. For heavy masonry work, that’s a real omission — you’ll want to buy one separately ($15–20) or your wrists will feel it.

Who Should Buy This

Buy it if: You already own DEWALT 20V or FLEXVOLT batteries. The bare-tool value here is excellent, and the performance jump with FLEXVOLT packs makes this the smartest upgrade path for existing DEWALT users. Also buy it if you’re a serious DIYer or light professional who does mixed drilling and driving work daily.

Skip it if: You’re starting fresh with no DEWALT batteries. You’ll end up spending $400+ by the time you add FLEXVOLT packs, and at that price you could get a full kit with larger batteries and a hard case from another brand. Also skip it if you only need a drill — the impact driver is great, but it’s not worth the premium if you’ll never use it.

FAQ

Q: Do I need FLEXVOLT batteries for this kit to work? No. The tools run perfectly fine on standard 20V batteries. The FLEXVOLT ADVANTAGE feature is a power boost, not a requirement.

Q: Will this drill handle concrete work? Yes, with the right bits. The hammer drill mode handles up to 1/4-inch anchors in standard concrete. For larger holes or rebar-embedded concrete, you need a rotary hammer.

Q: Are the batteries interchangeable with older DEWALT tools? Yes. The 20V batteries work with all DEWALT 20V MAX tools. The FLEXVOLT batteries work with both 20V and 60V tools.

The Verdict

Rating: 4.6/5

This is a genuinely excellent combo kit with one frustrating asterisk. The tools are top-tier, the ergonomics are improved, and the FLEXVOLT ADVANTAGE feature is real — not a marketing gimmick. But DEWALT’s decision to ship with standard 20V batteries undercuts the very feature that makes this kit special.

Buy it if you’re already in the DEWALT ecosystem or you’re willing to budget for FLEXVOLT batteries later. Skip it if you’re starting fresh and want maximum value out of the box. For existing DEWALT owners, this is the upgrade you’ve been waiting for — just budget for the batteries that unlock its full potential.
