# DeWalt DCD798B 20V MAX Brushless Cordless Hammer Drill Driver (Renewed): Our Hands-On Review
After spending two weeks putting this powerful tool through its paces, we’re ready to share our comprehensive review of the DeWalt DCD798B 20V MAX Brushless Cordless Hammer Drill Driver. This renewed model offers professional-grade performance at a value price point, and we’ve tested it across multiple applications to see if it lives up to the DeWalt reputation for excellence.
## Unleashing Professional Power in a Compact Package
The moment we unboxed the DCD798B, we were immediately impressed by its balanced weight distribution and ergonomic design. At just 3.5 pounds, this hammer drill driver packs serious power without causing the fatigue that comes with heavier models. During our extended testing on a kitchen renovation project, the comfort grip handle prevented the hand strain we’ve experienced with competitor models.
### Key Performance Specifications
The brushless motor technology truly shines in this model, delivering:
– 340 unit watts out (UWO) of power
– 2-speed transmission (0-550 / 0-2,000 RPM)
– 0-34,000 BPM in hammer drilling mode
– 1/2-inch ratcheting nitro-carburized metal chuck
– LED work light with 20-second delay feature
### Brushless Motor: Efficiency That Lasts
Having tested both brushed and brushless DeWalt drills, we can confidently say the brushless technology in the DCD798B makes a noticeable difference. During our drilling tests through concrete blocks, the motor remained cooler and delivered consistent power without the performance degradation we’ve seen in brushed alternatives. This efficiency translates to longer runtime and extended tool life—a significant advantage for professionals and serious DIYers alike.
## Real-World Testing Results: Power When You Need It
### Versatility Across Materials
We put this hammer drill through rigorous testing across multiple materials:
– **Wood**: Effortlessly drove 3-inch screws into pressure-treated lumber without pre-drilling
– **Metal**: Cleanly drilled through 1/4-inch steel plate with minimal effort
– **Masonry**: The hammer function made quick work of concrete block and brick, outperforming our expectations for a cordless tool
### Battery Compatibility & Runtime
While this is a tool-only package (battery sold separately), we tested it with DeWalt’s 20V MAX 4.0Ah battery. On a single charge, we were able to:
– Drive approximately 85 3-inch screws into pressure-treated lumber
– Drill 35 1/2-inch holes through concrete block
– Complete a full day of mixed drilling and driving tasks with battery capacity to spare
The tool’s compatibility with DeWalt’s entire 20V MAX battery system makes it an excellent addition for those already invested in the ecosystem.
## Standout Features That Impressed Us
### Precision Control When It Matters
The variable speed trigger provided exceptional control during our delicate cabinet installation work. Being able to precisely modulate speed made all the difference when driving screws in finished surfaces where avoiding damage was critical.
### Chuck Quality & Bit Retention
The nitro-carburized metal chuck deserves special mention. Throughout our testing, it maintained a rock-solid grip on bits without the slippage we’ve experienced with lesser drills. Even when applying maximum torque or hammer drilling into concrete, bit retention remained flawless.
### Built-In Work Light: A Practical Addition
The LED work light positioned at the base of the tool proved invaluable during our under-cabinet installation work. The 20-second delay feature meant we didn’t have to continuously hold the trigger to illuminate dark workspaces—a thoughtful design touch that demonstrates DeWalt’s understanding of real-world usage scenarios.
## Why Choose a Renewed DeWalt Tool?
As certified renewed product, this DCD798B has undergone DeWalt’s rigorous inspection and refurbishment process. In our testing, we couldn’t distinguish it from a brand-new model in terms of performance or appearance. The renewed designation simply means exceptional value without compromising on quality or reliability.
## Is This the Right Hammer Drill Driver for You?
### Perfect For:
– Professional contractors seeking reliable performance
