DeWalt 20V MAX* Brushless Cordless 1/2 in. Hammer Drill

As an avid DIY enthusiast and professional contractor, I've had my fair share of experiences with a wide range of tools. Recently, I've had the opportunity to put the DeWalt 20V MAX* Brushless Cordless 1/2 in. Hammer Drill (model DCD799B) through its paces. This review will cover my hands-on experience with this versatile and compact hammer drill, highlighting its strengths and areas where it could improve.

The first thing that struck me about this drill is its impressively compact design. With a tool head length of just 6.49 inches, it’s clear DeWalt engineered this model with tight spaces in mind. This feature alone makes it a valuable addition to my toolkit, as I often find myself working in confined areas where bulkier drills simply can’t fit. The lightweight form, weighing in at just over 40 ounces, also contributes to its ease of use, particularly during extended periods of drilling or driving.

Performance-wise, the DCD799B doesn’t disappoint. The brushless motor delivers up to 1,650 RPM, which is more than adequate for a variety of drilling tasks. I’ve found the torque to be both powerful and consistent, which is crucial for maintaining precision and efficiency on the job. The drill offers 552 UWO (Unit Watts Out), a measure of the power output, which translates to excellent performance in both drilling and driving applications. Whether I’m working on wood, metal, or masonry, this drill has consistently provided the power I need.

The 1/2 inch ratcheting chuck is another standout feature. It ensures secure bit retention, which is essential for preventing slippage during high-torque applications. I appreciate the keyless chuck design, which allows for quick and easy bit changes without the need for additional tools. However, it’s important to hand-tighten the chuck rather than relying on the drill’s power to do so. This ensures a more secure grip and reduces the risk of the chuck loosening during use.

One of the most practical features of the DCD799B is the integrated LED work light. This may seem like a small addition, but it’s incredibly useful when working in poorly lit areas. The LED light is bright and well-positioned, illuminating the work surface effectively and reducing the need for additional lighting.

Despite its many strengths, the drill isn’t without its drawbacks. During my testing, I encountered an issue with the chuck screw. While tightening a bolt, the chuck spun off, and upon inspection, I discovered that the screw had broken off in the housing. This was a surprising and somewhat concerning flaw, especially given DeWalt’s reputation for durability. It’s worth noting that this may have been an isolated incident, but it’s something to keep in mind if you’re considering this drill for heavy-duty use.

Another area where the DCD799B could improve is its compactness. While it’s already quite small compared to other models, I feel that a slightly more compact design would make it even more versatile, especially for those ultra-tight spots. That being said, this is a minor gripe and doesn’t significantly detract from the overall performance and usability of the tool.

In terms of battery life, the 20V MAX* system is reliable and long-lasting. I’ve found that a fully charged battery can easily handle a full day’s worth of light to moderate use. For more intensive tasks, having a spare battery on hand is advisable, but this is standard practice for any cordless tool.

Overall, the DeWalt 20V MAX* Brushless Cordless 1/2 in. Hammer Drill is a solid performer that excels in both power and precision. Its compact and lightweight design makes it ideal for a wide range of applications, from DIY projects to professional construction work. The integrated LED work light and secure bit retention further enhance its usability, making it a versatile tool for any toolkit.

Would I recommend this drill? Absolutely, with a few caveats. If you’re looking for a reliable, powerful, and compact hammer drill, the DCD799B is an excellent choice. However, be mindful of the potential issue with the chuck screw, and ensure you’re hand-tightening the chuck properly to avoid any mishaps. As long as you take these precautions, this drill will serve you well in a variety of tasks, delivering the performance and reliability that DeWalt is known for.
