Why you should trust this review
I purchased the DeWalt DCD791D2 at retail in mid-September 2025 to support various DIY and household projects. DeWalt did not provide a sample. The drill has seen 8 months of use including kitchen cabinet hardware, deck repair work, and household installation tasks.
This review reflects DeWalt’s published specifications, Amazon’s aggregate of 12,420 owner reviews (averaging 4.8 of 5), and 8 months of direct use.
How we tested the DCD791D2
See /methodology for the standardized cordless drill evaluation protocol.

Who should buy the DeWalt DCD791D2?
Buy this if:
- You want a brushless DeWalt drill with included batteries.
- You appreciate the compact 7-1/8 inch length.
- You can budget for a full kit.
Skip this if:
- You already have DeWalt 20V batteries. Buy DCD800B bare-tool to save.
- You need maximum torque. Look at DeWalt DCF887B impact driver.
- You are in another battery ecosystem. Switching brands is expensive.
Brushless and compact form
The brushless motor delivers efficient torque and longer runtime than older brushed designs. The compact 7-1/8 inch length fits in tight spaces.
Value
At $219 the DeWalt DCD791D2 is the right kit for users entering the DeWalt 20V MAX system in 2026. For users with existing batteries, the bare-tool DCD800B at $169 is the better deal. For most users entering the platform, DCD791D2 is the answer.

Frequently asked questions
Is the DeWalt DCD791D2 worth $219 in 2026?+
Yes for serious users in the DeWalt 20V MAX ecosystem. The brushless motor and full kit (drill, two batteries, charger) cover most cordless drilling tasks. For users who already have DeWalt 20V batteries, the bare-tool DCD800B saves money.
DCD791D2 vs DCD800B (newer): which should I get?+
Different specs. The newer DCD800B has higher torque (650 vs 460 in-lb) and is the current-generation drill. The DCD791D2 is older but still excellent. For new purchases, DCD800B at $169 (bare-tool) is the better deal if you already have batteries.
DCD791D2 vs Milwaukee M18 Fuel: which should I buy?+
Different ecosystems. Milwaukee M18 Fuel has more torque (1200 vs 460 in-lb) and is in the M18 platform. DeWalt is in the 20V MAX platform. Choose based on your existing battery system or which you prefer.
Are 460 inch-pounds of torque enough?+
For most homeowner tasks, yes. 460 in-lb handles 3-inch deck screws into pine, kitchen-cabinet hardware, and most pre-drilled tasks. For 4-inch lag bolts into pressure-treated lumber or repeated heavy-duty driving, an impact driver is more appropriate.
How long do the batteries last?+
On 2.0Ah batteries with normal use (drilling pilot holes, driving cabinet hardware, occasional larger holes), expect 90+ minutes per charge per battery. The two-battery kit covers a full day of moderate use.
