The DeWalt DCD800 and Milwaukee 2904 are not identical types of drill. The DCD800 is a drill/driver; the 2904 is a hammer drill/driver. Decide whether your work calls for that extra function before comparing the brands.
This is a comparison of published manufacturer information, checked on 14 September 2026. We have not tested these tools side by side, measured their runtime or used them on a two-year jobsite trial. The photograph shows the actual DCD800 and comes from the manufacturer; it does not depict the Milwaukee tool.

The suffix matters. A kit with a similar model name may contain different batteries, a charger or a case. Compare the contents of the exact package you will order, not a photograph borrowed from another bundle.
Start with the job, not a brand winner
For a buying decision centred on drilling and screwdriving, the DCD800 belongs on a drill/driver shortlist. If you are specifically shopping for a hammer-drill function, the 2904 offers that function and the DCD800 does not. A closer comparison within DeWalt’s range would require checking a hammer-drill model separately.
This distinction is not permission to use either tool on any material. Read the manufacturer’s manual for the task, bit, operating mode and precautions. A hammer drill is not automatically a replacement for every other drilling tool.
We do not declare one model faster in wood or better at difficult holes: those conclusions would need a controlled test with documented bits, batteries, materials and settings.
Price the battery platform you actually need
If you already own suitable manufacturer-approved batteries and a charger, a tool-only purchase may be worth comparing with a kit. If this is your first cordless tool, the bare-tool price is only part of your starting cost.
Make a short worksheet with separate lines for the tool, compatible battery, charger, required accessories and delivery. Use current prices from the exact listings. A hypothetical lower bare-tool price can become a higher total if you need to buy the rest of the system separately.
Check battery compatibility in the manufacturer’s documentation. Do not assume that similar-looking battery packs are interchangeable, or that an adapter makes an unsupported combination suitable.
Do not turn incompatible specifications into a score
Torque, speed and other manufacturer performance measures answer different questions. They do not establish an overall winner on their own. In particular, do not compare a torque figure with a power figure as if they use the same units.
Weight and size comparisons also need matching conditions: whether a battery is fitted, which battery is used, and whether the published dimensions include accessories. We have avoided a single numerical ranking because those details affect what the comparison means.
Before placing an order
Confirm the exact model suffix, drilling functions, included items, battery compatibility, delivered price and applicable warranty terms. Where possible, handle the tool with the battery you intend to use; comfort cannot be established from a product photograph.
Choose the DCD800 shortlist for a drill/driver comparison, or the 2904 shortlist when you are comparing hammer drill/drivers. Then compare equivalent packages within that category.
