DeWalt Quick Connect Chuck: Which One Fits Your Tool?

A chuck is the part at the front of a drill that grips the bit. DeWalt makes several chucks and adapters for its tools, and one of the most useful is a quick connect chuck that snaps into an impact driver so it can hold round-shank drill bits. Separately, many DeWalt owners go looking for a replacement chuck when the original on their drill wears out, slips or gets damaged. Both searches lead to the same shelf, which mixes genuine DeWalt parts with third-party replacements built to fit DeWalt tools.
The six products here differ in who makes them and what they fit: two genuine DeWalt chucks, and four third-party replacements that match specific DeWalt part numbers and drill or rotary hammer models.

DEWALT Drill Chuck for Impact Driver, Quick Connect (DW0521)
Price and specifications are read from the Amazon product page and can change.
DEWALT Drill Chuck for Impact Driver
Best for: Impact driver owners who need to drill
Pros
- Genuine DeWalt DW0521
- 1/4 inch hex quick connect
- One-handed single sleeve
- All-metal construction
Cons
- 3/8 inch keyless capacity
- 90 day warranty
The DEWALT Drill Chuck for Impact Driver, model DW0521, is the genuine DeWalt quick connect chuck most people mean when they search for this product. An impact driver normally only accepts bits with a 1/4-inch hex shank, the six-sided shape on screwdriver bits. Many drill bits have round shanks, so they will not fit. The DW0521 has a 1/4-inch hex shank on the back that snaps into the impact driver, and a small keyless chuck on the front that grips round bits up to 3/8 inch, according to the included components line.
That lets you switch from driving screws to drilling a pilot hole without swapping tools. It has a single-sleeve design, so you tighten it with one hand by twisting the collar, and it is all metal for durability. DeWalt backs it with a 90-day warranty and a one-year free service contract. The listing does not specify its length or weight.
This is the right pick for someone who owns a DeWalt impact driver and wants to drill small holes without carrying a second tool. It is not a replacement chuck for a drill; if your drill’s chuck is worn, look at the replacement options below. It also makes an inexpensive add-on gift for anyone who received an impact driver or a DeWalt impact wrench.
N825538 Drill Quick Connect Chuck for DCD445B and DCD443B Repairs
Crypticorps
N825538 Drill Quick Connect Chuck for Dewalt, Replacement DCD445B DCD443B
Price and specifications are read from the Amazon product page and can change.
N825538 Drill Quick Connect Chuck
Best for: Repairing DCD445B or DCD443B drills
Pros
- Matches part N825538
- Named DCD445B and DCD443B fit
Cons
- Third-party Crypticorps, not DeWalt
- Generic listing text, few specs
The N825538 Drill Quick Connect Chuck is sold by Crypticorps, a third-party brand, as a replacement for DeWalt part number N825538, and it names the DCD445B and DCD443B as the tools it fits.
The listing gives very few specifics. It does not state the chuck’s capacity, material, dimensions or mount type, and much of the text is generic, even mentioning lawnmowers, brushcutters and chainsaws, which are unrelated to a drill chuck. The seller itself asks buyers to compare the photo and dimensions against their original part before ordering.
This suits someone who has confirmed their tool is a DCD445B or DCD443B and needs part N825538. If you are unsure of your tool model, check the nameplate on the tool first. For a genuine DeWalt quick connect accessory, the DW0521 is the only option here.
#N403111 Drill Chuck Quick Coupling for D25134 and D25124 Rotary Hammers
Tovyvw
Tovyvw #N403111 Drill Chuck Quick Coupling Fits D25134 D25124 SDS Plus Rotary Hammer Replacement Part New Compatible with DeWalt
Price and specifications are read from the Amazon product page and can change.
#N403111 Drill Chuck Quick Coupling Fits
Best for: D25134 and D25124 rotary hammer owners
Pros
- Replaces part N403111
- Metal, 35 g
- Easy install per listing
Cons
- Third-party Tovyvw, not OEM
- Only for two named hammers
The #N403111 Drill Chuck Quick Coupling Fits DeWalt D25134 and D25124 SDS Plus rotary hammers. It is made by Tovyvw and clearly labeled as not an OEM part, meaning it is not made by DeWalt, though the seller says it meets OEM manufacturing requirements and is functionally equivalent. SDS Plus is a bit-holding system used on rotary hammers, where bits slide into a slotted socket rather than being clamped.
It is metal, weighs 35 grams, and the package contains one quick coupling. The listing says it is easy to install. It does not provide dimensions or detailed installation steps.
This fits owners of those two rotary hammers who need to replace a damaged or worn quick coupling. It will not fit ordinary drills or impact drivers.
DeWalt DT7005-QZ Chuck with SDS Adaptor
Dewalt
DeWalt DT7005-QZ Chuck, One Size
Price and specifications are read from the Amazon product page and can change.
DeWalt DT7005-QZ Chuck
Best for: Adding a round-shank chuck to SDS tools
Pros
- Genuine DeWalt DT7005-QZ
- 13mm chuck with SDS adaptor
- 1/2-20 UNC thread
- 1 year warranty
Cons
- Very short feature list
The DeWalt DT7005-QZ Chuck is a genuine DeWalt 13mm chuck supplied with an SDS adaptor. That combination lets an SDS tool hold round-shank bits, the same kind of problem the DW0521 solves for impact drivers. The chuck thread is 1/2″-20 UNC, a common drill chuck thread size, and it carries a one-year warranty.
The feature list is very short, and the description is a brand history rather than product details, so the listing does not specify which SDS tools the adaptor fits or the chuck’s weight. Check your tool’s manual before buying.
This suits owners of SDS rotary hammers who want to use regular drill bits for lighter jobs.
N472497 N250759 Replace for DeWALT DCD771 and DCD777 Drills
Best for: DCD771 and DCD777 chuck replacement
Pros
- 1/2 inch capacity
- Long compatibility list
- Mounting screw included
Cons
- Third-party KIMGU, not DeWalt
- Item count listed as 20
The N472497 N250759 Replace for DeWALT DCD771 chuck is a third-party KIMGU replacement with a 1/2-inch capacity and a 1/2-20 UNC thread. It lists fits for the DCD771, DCD776, DCD777, DCD7771, DCD7781, DCD775, DCD780, DCD734, DCD778, DCD798B and several older 14.4V and 18V models, and it matches DeWalt part numbers N472497, N250759, 330075-73, 330075-74 and others. It includes a screw for mounting; chucks are often held on by a reverse-threaded screw inside the jaws.
The spec table lists 20 items, which conflicts with a single chuck, so check the package contents. The listing does not specify material, weight or whether it is a single-sleeve or ratcheting design, and it gives no installation instructions.
This suits owners of a DCD771 or DCD777 whose chuck slips, wobbles or no longer closes fully. Because the DCD771 is one of DeWalt’s most common compact drills, this is likely the replacement many readers need. If you are not comfortable removing the retaining screw and unthreading the old chuck, a tool repair shop can do the swap.
N196034 CHuck Keyless Replace for DeWALT DCD790 Series
Best for: DCD790 to DCD797 series drills
Pros
- Keyless 1/2-20 UNC chuck
- Replaces several obsolete part numbers
- 25 kg
Cons
- Third-party KIMGU, not DeWalt
- Compatibility list is hard to read
The N196034 CHuck Keyless Replace for DeWALT is another KIMGU keyless chuck, thread 1/2-20 UNC, weighing 0.25 kg. It lists fits for the DCD790, DCD791, DCD792, DCD795, DCD796 and DCD797, plus many older drills, and says it replaces obsolete DeWalt part numbers such as N442696, N442695 and 330075-91. The compatibility text is long and cut off, so confirm your exact model and type number.
Keyless means you tighten the chuck by hand instead of using a separate chuck key. The listing does not state the chuck’s maximum bit capacity, although the 1/2-20 UNC thread is typical of 1/2-inch drills.
This suits owners of DCD79x drills needing a new keyless chuck. If your drill is a DCD771 or DCD777 instead, the other KIMGU chuck above lists those models.
How to Choose the Right DeWalt Chuck
First decide what you need. To drill with an impact driver, you need a quick connect chuck like the DW0521. To fix a worn drill, you need a replacement chuck matched to your drill model.
Find your model number. It is printed on the tool’s nameplate, often with a “Type” number. Match both against the listing’s compatibility list.
Check the thread. Several chucks here use 1/2-20 UNC, which describes the diameter and thread pitch of the drill’s spindle. Your drill must match, or the chuck will not screw on.
Look at capacity. A 1/2-inch chuck holds bigger bits than a 3/8-inch one. The DW0521 tops out at 3/8 inch, which is fine for pilot holes but not large bits.
Decide on genuine versus third-party. The DW0521 and DT7005-QZ are DeWalt parts; the rest are third-party replacements. Keep your workshop tidy after swapping parts with a DeWalt jobsite blower.
