Before You Buy

Before selecting a tool configuration, consider what the retail listings do and do not include. None of these six DEWALT listings include drill bit sets, screwdriver bits, spade cutters, or carbide masonry bits. You must procure appropriate tooling accessories separately based on the specific material you intend to drill. Furthermore, while the packaged kits provide soft storage bags, the listings do not specify waterproof ratings or rigid shell reinforcement, meaning harsh jobsite transportation may require upgrading to a heavy-duty toolbox.

Power configurations and battery specifications also vary significantly across this range. The DCD777B listing clearly notes that it is a bare tool, meaning battery packs and chargers must be purchased separately. While the DCK240C2 and DCD771C2 include entry-level battery packs (the DCD771C2 listing specifying 1.3 Ah capacity), the listings do not specify battery charge times or onboard fuel gauges for these entry packs. If your schedule requires non-stop daily drilling, evaluating battery amp-hour capacity will prevent unexpected jobsite delays.

FAQ

What is the difference between brushed and brushless DEWALT drills?

Brushed models like the DCD771 use physical carbon brushes to conduct electricity to the motor armature, creating friction and operating heat over time. Brushless models like the DCD777 and DCD806 utilize electronic microprocessors to power the motor, delivering more runtime per charge (up to 57 percent more in the DCD777), reduced maintenance, and higher working efficiency.

Can the DCD771 drill bore into concrete or brick walls?

No. The product listing for the DCD771C2 explicitly states that it is not suitable for drilling into concrete or masonry, as it lacks a percussive hammer mechanism. For drilling into concrete, brick, or stone, the DCD806 hammer drill included in the DCK250QQ2 kit is engineered specifically for masonry work.

What does UWO mean on DEWALT drill specifications?

UWO stands for Unit Watts Out. It measures the maximum power output delivered at the drill chuck, combining speed and torque under working resistance. For example, the brushed DCD771 outputs 300 UWO, while the brushless DCD777 delivers 340 UWO, representing greater power capability under load.

Are batteries interchangeable across all these DEWALT 20V MAX drills?

Yes. Every tool in this guide operates on the 20V MAX lithium-ion battery system. The compact 1.3 Ah packs, the 2.0 Ah packs, and the 4.0 Ah POWERPACK batteries can physically slide onto and power any of the 20V MAX drill bodies, including the DCD777B bare tool.

Why choose an impact driver combo kit over a standalone drill driver?

A standalone drill driver is designed for smooth hole boring and controlled clutch driving, but driving long lag screws can cause high wrist torque and screw stripping. An impact driver combines high-speed rotational force with rapid concussive blows, delivering significantly higher torque (such as 1825 in-lb on the DCF845) without reactive wrist twisting.
