Design and Build Quality
Both drills share a robust DeWalt-grade build, but the DCD777 edges ahead in terms of compactness and weight. It’s nearly 1 pound lighter, which makes a significant difference over extended use, especially overhead or in tight spaces.
DCD771 is slightly longer and bulkier, which can be limiting in cabinetry or when reaching into corners. However, it still offers a durable, ergonomic handle and reliable performance.
Winner: DCD777, for its compact and lightweight form factor.
Motor Technology: Brushed vs Brushless
The biggest difference is under the hood:
- DCD771 uses a brushed motor, a more traditional and cost-effective technology. While it performs well, brushed motors wear down faster and generate more heat.
- DCD777 features a brushless motor, which is more efficient, produces less heat, and generally lasts longer. It also helps extend battery life by drawing power more efficiently.
Brushless motors are usually reserved for higher-end or professional-grade tools, which justifies the price bump of the DCD777.
Winner: DCD777, for superior motor technology.
Performance and Battery Efficiency
Despite both being powered by DeWalt’s 20V Max battery platform, the DCD777’s brushless motor delivers more torque and higher speed. You’ll especially notice the benefit during demanding tasks like driving long screws into hardwood or drilling larger holes.
The DCD777 also makes better use of battery power, giving you up to 30% more runtime than the DCD771 with the same battery size.
Winner: DCD777, for enhanced performance and energy efficiency.
