DeWalt Flexvolt Advantage Drill: Enhanced Power For Professional Results

The DeWalt Flexvolt Advantage Drill represents a significant evolution in DeWalt’s power tool lineup, bridging the gap between their standard 20V MAX and higher-powered Flexvolt systems. This innovative drill delivers exceptional performance for professionals and serious DIYers who demand reliable power and versatility. Let’s explore what makes this drill stand out in the crowded cordless tool market and whether it deserves a place in your toolkit.

Product Specifications

Pros and Cons

Understanding Flexvolt Advantage Technology

The cornerstone of this drill’s performance is DeWalt’s Flexvolt Advantage technology. Unlike standard 20V MAX tools, these drills contain special circuitry that detects when a higher-capacity Flexvolt battery is connected. When paired with a Flexvolt battery, the drill delivers up to 42% more power compared to using standard 20V MAX batteries.

This adaptive power management system gives users the best of both worlds: the ability to use their existing 20V MAX batteries for lighter tasks while having the option to significantly boost performance for demanding applications by simply swapping to a Flexvolt battery.

How It Works

When you connect a Flexvolt battery (which operates at 20V in this tool), the drill’s internal electronics detect the higher-capacity power source and adjust performance accordingly. The brushless motor can draw more current from these advanced batteries, resulting in higher torque and sustained power during heavy-duty applications.

Performance Analysis

Power and Torque

The DCD999B hammer drill delivers impressive torque that makes quick work of drilling through tough materials. With a standard 20V MAX battery, the drill performs admirably for most household tasks. However, when paired with a Flexvolt battery, it truly shines in demanding applications like drilling through concrete, masonry, or driving large fasteners.

During testing, the drill easily handled 1-inch auger bits through pressure-treated lumber and 1/2-inch holes through concrete with minimal bogging down. The three-speed transmission allows for optimal control, with the lowest speed delivering maximum torque for tough materials.

Battery Life and Efficiency

The brushless motor technology significantly extends runtime compared to brushed alternatives. With a standard 5Ah 20V MAX battery, you can expect to complete multiple projects before needing a recharge. When using a 6Ah or 9Ah Flexvolt battery, runtime increases substantially, even during high-demand applications.

One contractor reported drilling over 100 4-inch holes for potlights in drywall on a single charge with a Flexvolt battery. However, it’s worth noting that heavy drywall work can lead to dust ingress issues over time, as mentioned in user feedback.

Ergonomics and Handling

At approximately 4.7 pounds (tool only), the Flexvolt Advantage drill is heavier than DeWalt’s standard 20V MAX drills. This additional weight is noticeable during extended overhead work but provides a balanced feel when drilling into dense materials, where the extra mass helps counter resistance.

The rubberized grip offers excellent control and comfort, while the LED work light effectively illuminates the work area. The three-position side handle provides additional stability for high-torque applications, though some users report it can be cumbersome in tight spaces.

Durability and Construction

Built to DeWalt’s professional standards, the Flexvolt Advantage drill features robust construction with impact-resistant housing. The all-metal ratcheting chuck maintains its grip even under significant torque, preventing bit slippage during demanding applications.

Several users report these drills holding up well in construction environments, though there are mentions of dust infiltration affecting the trigger mechanism after extensive use in drywall applications. This suggests that while the drill is well-sealed, it may benefit from occasional compressed air cleaning when used in dusty environments.

Comparison with Alternatives

DeWalt Flexvolt Advantage vs. Standard XR

The primary difference between the Flexvolt Advantage drill and DeWalt’s standard 20V MAX XR drills is the adaptive power technology. While both feature brushless motors and similar designs, the Flexvolt Advantage model delivers significantly more power when paired with Flexvolt batteries.

For professionals who already own Flexvolt batteries or frequently tackle demanding applications, the upgrade makes sense. However, for occasional users or those working primarily with softer materials, the standard XR drill may provide better value.

Comparison with Other Brands

When compared to competitors like Milwaukee’s M18 FUEL hammer drill, the DeWalt Flexvolt Advantage offers comparable performance with the unique advantage of power scalability. Milwaukee’s offering delivers consistent high performance but lacks the ability to boost power with different batteries.

The DeWalt system’s major advantage is its ecosystem compatibility, allowing users to leverage their existing battery investments while gaining performance benefits.

Applications and Use Cases

Construction and Remodeling

The Flexvolt Advantage drill excels in construction environments where versatility is key. From driving lag bolts into framing to drilling holes in concrete for anchors, its adaptive power system handles varying demands without requiring multiple specialized tools.

Electrical and Plumbing Work

Electricians and plumbers benefit from the drill’s ability to switch between precision work (like drilling small pilot holes) and power-intensive tasks (such as boring through floor joists) simply by changing batteries.

Woodworking

For woodworkers, the drill’s three-speed transmission provides the control needed for delicate work while having reserve power for larger forstner bits or augers when necessary.

User Feedback and Real-World Performance

Professional users consistently highlight the drill’s power and versatility. One contractor mentioned, “The Flexvolt Advantage hammer drill had promised to be a game-changer, and as a professional in the construction industry, having the supreme power when needed makes all the difference.”

However, some users report issues with dust infiltration affecting the trigger mechanism after extensive use in drywall applications. As one user noted, “I got a DeWalt cordless hammer/drill XR that’s on its way out after hundreds of 4-inch holes for potlights in drywall—it’s just filled with dust, and the trigger works intermittently.” This suggests that while the Flexvolt Advantage drill is well-sealed, it may benefit from occasional maintenance when used in extremely dusty environments.

Final Verdict

The DeWalt Flexvolt Advantage Drill represents a significant innovation in the cordless tool market, effectively bridging the gap between standard 20V tools and more powerful options. Its ability to adapt performance based on the connected battery makes it uniquely versatile for professionals who face varying job demands.

For users already invested in the DeWalt 20V MAX ecosystem, especially those who own Flexvolt batteries, this drill offers compelling performance advantages. The power boost with Flexvolt batteries makes it capable of handling tasks that would typically require corded tools or specialized high-voltage cordless options.

However, the premium price point and slightly heavier weight compared to standard drills mean it’s most appropriate for professionals and serious DIYers who will leverage its full capabilities. Occasional users might find better value in DeWalt’s standard 20V MAX offerings.

Who Should Buy This Drill

Ideal for:

– Professional contractors who regularly tackle demanding drilling applications
– Remodelers who need versatility across various materials and applications
– Existing DeWalt 20V MAX or Flexvolt system users looking to maximize their battery investment
– Serious DIYers who want professional-grade performance for occasional heavy-duty projects

Less suitable for:

– Casual users who primarily handle light-duty household tasks
– Budget-conscious buyers who won’t utilize the adaptive power features
– Users who need the absolute lightest tool for extended overhead work
– Those who exclusively work with soft materials where extra power isn’t necessary

The DeWalt Flexvolt Advantage Drill delivers on its promise of adaptive power, providing a versatile solution for professionals who demand performance across a spectrum of applications. While it commands a premium price, its flexibility and power make it a worthwhile investment for those who will leverage its capabilities.
