How to choose
Power Source and Compatibility
When selecting a hammer drill, determine if you require corded or cordless operation. The DWD520K utilizes a 10-amp corded power supply for consistent, tethered performance. Conversely, the DCD799B, DCD805B, and the 20V rotary hammer operate on the 20V MAX battery platform. Ensure your existing battery inventory aligns with these tools, as many cordless models are sold as bare tools. If you already own DeWalt 20V batteries, these cordless options provide portability and convenience for remote job sites, whereas corded units remain ideal for stationary tasks where continuous power is essential without battery management.
Brushless vs. Brushed Motors
Motor technology significantly influences tool longevity and efficiency. Brushless motors, found in the DCD799B, DCD805B, and the generic cordless hammer drill, generally offer improved performance and maintenance profiles compared to traditional brushed motors. These brushless units are designed to handle demanding applications like concrete and metalworking while maintaining a compact form factor. While brushed motors remain effective for standard drilling tasks, brushless options are increasingly prioritized for those seeking modern efficiency in their workshop equipment. Check the specifications for each model to confirm the inclusion of brushless technology to ensure your tool meets your long-term project expectations.
Size and Ergonomics
Ergonomics are crucial for user comfort during prolonged operation. The DCD799B is marketed specifically as part of the ATOMIC Compact Series, making it a suitable choice for tight spaces where maneuverability is a priority. The DCD805B also emphasizes a compact design with a 1/2-inch chuck. For more heavy-duty applications, the 20V D-Handle rotary hammer offers a different grip configuration designed to handle 1-inch capacity tasks. Evaluate the physical dimensions and handle design of each tool against your specific workspace constraints and the physical requirements of your drilling projects to ensure the best fit for your hand.
Chuck Size and Capacity
The chuck size dictates the diameter of the bits you can use. Most standard hammer drills in this selection, including the DCD799B, DCD805B, and the DWD520K, feature a 1/2-inch chuck, which accommodates a wide range of common masonry and metal bits. The 20V Rotary Hammer is rated for a 1-inch capacity, indicating it is engineered for more aggressive material removal. When choosing, consider the diameter of the holes you intend to drill. If your work involves large-diameter masonry holes, a dedicated rotary hammer may provide better results than a standard 1/2-inch hammer drill.
Variable Speed and Control
Control features like variable speed settings allow for precision across various materials. The DCD805B highlights a 2-speed setting and variable speed control, which is essential for preventing bit walking or material damage. Similarly, the DWD520K provides a pistol grip configuration that assists with control during heavy-duty drilling. Evaluate the speed adjustability of each unit to ensure you can match the RPM to the material density. Having multiple speed settings allows you to transition between delicate drilling tasks and high-torque masonry work without needing multiple tools to complete your project effectively.
Frequently asked questions
What is the primary difference between the DCD799B and the DCD805B?
Both the DCD799B and DCD805B are 20V MAX brushless cordless hammer drills featuring a 1/2-inch chuck. The DCD799B is part of the ATOMIC Compact Series, emphasizing a smaller profile for tight spaces. The DCD805B features a 2-speed setting and variable speed control, focusing on versatility for different materials. Both are sold as bare tools, meaning they do not include batteries or chargers. Your choice should depend on whether you prioritize maximum compactness or specific speed control options for your drilling tasks.
Can I use my existing DeWalt 20V batteries with these cordless hammer drills?
Yes, models such as the DCD799B, DCD805B, and the 20V Rotary Hammer are designed to be compatible with the DeWalt 20V MAX battery ecosystem. Since these are sold as bare tools, they rely on you having an existing supply of compatible 20V batteries. Always verify the specific battery model numbers if you have older or specialty batteries to ensure they seat correctly in the tool housing provided for these specific cordless hammer drill models.
Is a corded hammer drill like the DWD520K better for concrete?
The DWD520K is a 10-amp corded hammer drill with a pistol grip. Because it is corded, it provides a consistent power source that does not depend on battery charge levels, which can be advantageous for long-duration concrete drilling. While the cordless brushless models listed are rated for concrete, a corded unit is often chosen for stationary work where access to an electrical outlet is guaranteed. It remains a reliable option for heavy-duty applications requiring sustained power output.
What does 'Tool Only' mean in these product listings?
The 'Tool Only' designation, found on the DCD799B, DCD805B, and the generic cordless hammer drill, indicates that the package includes the drill itself but excludes essential accessories like batteries, chargers, or carrying cases. This is a common purchasing option for professionals or DIYers who have already invested in a specific battery platform. It allows users to expand their tool collection without paying for redundant chargers or batteries they may already own for their other DeWalt power tools.
Which hammer drill is best for tight spaces?
The DCD799B 20V MAX ATOMIC Compact Series is specifically marketed for its compact design. Its brushless motor allows for a smaller overall footprint without sacrificing the 1/2-inch chuck size, making it a strong candidate for drilling in confined areas where larger, full-size hammer drills might be difficult to maneuver. If your workspace is limited, prioritizing this compact series model over larger, standard-sized hammer drills will likely provide the best clearance and ease of operation for your specific home repair projects.
Bottom line
When selecting a hammer drill, the strongest fit depends on your existing power ecosystem and the scale of your projects. For users already committed to the DeWalt 20V platform, the DCD805B offers a robust balance of brushless efficiency, variable speed control, and a standard 1/2-inch capacity suitable for most masonry and metalworking. If space is your primary constraint, the DCD799B ATOMIC Compact Series provides a specialized, smaller footprint. For those requiring continuous, high-torque power for masonry without the concern of battery life, the corded 10-amp DWD520K remains a reliable, high-rated choice. These tools cover the spectrum from compact portability to heavy-duty stationary performance, ensuring that whether you are a professional or a homeowner, there is a configuration that matches your specific drilling requirements.
Deciding between these options requires assessing your mobility needs and battery inventory. If you prioritize freedom of movement and already own DeWalt 20V batteries, the DCD805B or DCD799B are the logical choices. For users who prefer a single, corded solution that is always ready for heavy-duty work, the DWD520K is the superior option. Finally, if your work strictly involves intensive concrete drilling, the 1-inch capacity of the 20V Rotary Hammer may be necessary. Match the tool's motor type, power source, and size to the frequency and intensity of your tasks to find the most effective addition to your workshop.
