Overview
The Dewalt DCD771B operates on a 20-volt battery platform with a 5-amp battery, reaching 1,500 RPM no-load speed. At 3.3 pounds it is a manageable weight for a drill with a large-capacity battery pack. The 5-amp rating is the highest battery capacity among the 20V drills in this batch, which translates directly to longer runtime between charges.
At $69.99, the DCD771B is priced below mid-range branded competitors while delivering specs that rival them. The 4.6-star average from 1,174 reviews reflects strong owner endorsement, and 300 units bought last month confirms active ongoing demand in the DEWALT platform segment.
The 1,500 RPM top speed is competitive for a 20V drill, sitting well above the 650 to 750 RPM range of budget entry models while keeping the tool accessible for general use. DEWALT's 20V MAX platform is one of the broadest in the industry, meaning buyers entering this ecosystem gain access to a large range of compatible tools.
Pros
- 5-amp battery is the largest capacity among 20V drills in this batch
- 1,500 RPM top speed is strong for a $69.99 20V cordless drill
- 3.3-pound weight is reasonable given the large battery pack
- 4.6 stars from 1,174 reviews shows consistent owner satisfaction
- DEWALT 20V MAX ecosystem is among the widest available for cross-tool compatibility
Cons
- Tool-only versions may be available at lower cost if you already own DEWALT 20V batteries
- 3.3 pounds is heavier than compact 12V or lightweight 8V options in the category
- 1,500 RPM is capped below the fastest cordless options at 1,800 RPM

Performance notes
Battery powered at 20 volts and 5 amps, 1,500 RPM no-load speed, 3.3 pounds. The 5-amp battery is the defining spec advantage here: it supports extended drilling and driving sessions before a recharge is needed, a practical benefit over the 1.3-amp to 2-amp packs found in lighter-duty 20V options. The DEWALT 20V MAX platform enables sharing batteries across drills, saws, and impact drivers.
What buyers say
Owners in the 1,174-review pool respond well to the battery performance and the overall DEWALT build quality. Feedback patterns show buyers frequently mention this as an upgrade from lower-amp or lower-speed drills. The most common criticism involves price relative to tool-only deals when batteries are already owned.
