Problems, parts and running costs

Summary

A compact 20V MAX XR brushless 1/2-in hammer drill/driver sold as a bare tool, with two speeds, a metal ratcheting chuck and a pivoting LED.

Strengths

  • Brushless motor, metal ratcheting chuck and two-speed transmission cover wood, metal, masonry and screwdriving in one compact tool.
  • 7-in body is about 1/2 in shorter than DCD796, and the pivoting LED doubles as a work light.
  • Existing DEWALT 20V MAX batteries remove the biggest added cost for owners already on the platform.
  • Independent trade reviews (Tool Box Buzz, Pro Tool Reviews) praised balance and the work light.
  • DEWALT publishes an exploded diagram and replacement parts for Type 1.

Weaknesses

  • Bare tool: no battery or charger, so a new DEWALT user faces a real added purchase.
  • Blows per minute, weight and full dimensions are not published on the manufacturer page or in the US manual; the 34,000 BPM figure is unverified.
  • The 40% output claim depends on specific batteries and is not an independently measured 40% faster drilling.
  • Kickback risk in drill and hammer modes: DCD805 lacks the anti-rotation sensor that DCD806 has.
  • Chuck loosening or wobble reports exist from owners, though none were confirmed as defects.
  • US and international manuals give different masonry capacity figures, so the 13 mm international figure should not be treated as a US recommendation.

Chuck and kickback

Owners in r/Dewalt describe a chuck that fully unscrewed during a 6-in hole-saw job in 2023, then kept loosening; the US manual’s recommended wood hole-saw capacity is 3 in, so that load was well beyond the listed size. Another owner reported visible wobble after about six months and two uses, with commenters disagreeing whether the bit holder or the chuck was at fault; no dial-indicator measurement settled it. A third reported cutouts on 2-1/8-in hole saws and 1-in auger bits, with replies favoring low gear and sharp bits and one unverified commenter claiming to work in a DEWALT service center. None of these are confirmed defects or give a failure rate.

The DCD805 feature sheet does not list anti-rotation protection, while the DCD806 does. DEWALT’s manual warns that a stalled drill can twist suddenly, and the numbered clutch is for screwdriving rather than universal anti-kickback duty. Owners also note there is no practical side-handle mount. Use controlled grip, supported workpieces and low gear for large holes; consider the DCD806 or a dedicated high-torque drill with a side handle for demanding work.

A community tip about hand-tightening the ratcheting chuck then backing off one click is unverified and is not a manufacturer instruction.

Home Depot listed DCD805B at $69.65 in October 2026, marked down from a displayed $199, with a 90-day return policy shown; verify final cart, store and stock. Ace Hardware listed the same bare tool at $199. A ShopSavvy snapshot dated September 10, 2026 showed Walmart at $117.55, Sears at $135.75 and Ace, Lowe’s and Home Depot at $179; those are older snapshot offers, not guaranteed stock. Home Depot listed DCD800B at $151.74 and DCD806B at $199.

On those figures: $70–100 from a trusted authorized seller is excellent value if you already own batteries; $100–140 is reasonable; above $150, compare the DCD800B if you do not need hammer mode; near $199, the DCD806B buys anti-rotation protection for about the same money. The DCD805D2 kit bundles the drill with 2 × 2Ah batteries, a charger and a bag, but no reliable October 2026 kit checkout price was established.

Parts and running costs

PartSelect listed Type 1 parts during the October 2026 check: metal keyless chuck (OEM N928691) at $35.42 in stock; speed selector (N393603) at $6.40; forward/reverse button (N399342) at $6.40; pivoting LED assembly (N883994) at $18.65 on special order; housing (NA065950) at $13.47 on special order; small hardware (Torx screw 682211-00, detent spring N014681, roll pin N071836) around $6.40 each. Replace on failure or damage, not on a schedule. DEWALT points owners to ServiceNet and warns that unapproved repairs during warranty can jeopardize claims.

Battery costs dominate ownership: Home Depot pages showed DCB203 2Ah at $84.86 to $98.98 and DCB205 5Ah at $119 promotional versus $169 standard. The DCD805D2 kit includes a DCB112 charger; a verified standalone charger price was not found. The DCE042 TOOL CONNECT chip, bits, hole saws and screws are job-specific consumables with no established annual cost.

Running costs are modest in electricity but depend on use. An illustrative calculation only: 50 full charges of a nominal 18V × 2Ah (36 Wh) DCB203 is 1.8 kWh of battery energy; at an assumed 75% wall-to-battery efficiency that is 2.4 kWh a year, or about $0.48 a year at an assumed $0.20/kWh. Brushless motors need no carbon brushes, and no manufacturer-specified annual service interval was found. Battery or accessory spending can far exceed charging cost.

Is it worth it?

For a DEWALT 20V owner who needs occasional masonry drilling, DCD805B is a strong buy at $70–100 and reasonable at $100–140. Above $150, check the DCD800B if masonry is not required, and near $199 the DCD806B’s anti-rotation sensor is the better spend. The tool’s published strengths are concrete (brushless motor, metal chuck, two speeds, compact body, pivoting LED), but its gaps are real too: no verified blows-per-minute figure, no published weight or full dimensions, a bare-tool purchase, and owner reports of chuck loosening and wobble that were never confirmed as defects. No independent instrumented test or readable owner-review content for exact DCD805B was found, so long-term durability stays unverified.

Which model this is

This page covers the bare-tool DCD805B, the 20V MAX XR brushless 1/2-in hammer drill/driver. A kit variant, DCD805D2, adds 2 × DCB203 batteries, a DCB112 charger and a bag, and Home Depot also lists a DCD805BWDCB206C kit with a 6.0 Ah battery. The shared instruction manual covers both DCD800 and DCD805, and DCD805 is the hammer-drill variant with masonry capability. It is not the shorter non-hammer DCD800 and not the newer DCD806 with its anti-rotation sensor. No separate mechanical revision of DCD805B was found; differences are kit and battery configurations. Retailers use varied names (“Compact Cordless Hammer Drill”, “XR Compact Hammer Drill”) for the same model number.
