This comparison is fundamentally about one decision: do you need a hammer drill? If you ever drill into concrete, brick, block, or stone -- or anchor hardware to masonry -- the DCD998W1 XR is the answer, full stop. If you drill into wood and metal only, the DCD708B ATOMIC handles that work well at a significantly lower price and in a more compact, lighter package.
But it's not quite that simple, because there's also a massive torque gap between these tools -- 370 in-lbs for the ATOMIC versus 1025 in-lbs for the XR. That's a nearly 3x difference that matters beyond just masonry work. I've used both drills extensively and I'll tell you exactly where each tool earns its place and where the other falls short.
Spec-by-Spec Comparison
DeWalt ATOMIC 20V MAX 1/2" Drill/Driver -- In-Depth
The DeWalt DCD708B ATOMIC is built around a clear value proposition: maximum compact geometry at an accessible price point, with brushless motor efficiency that punches above its price tier. At 2.4 lbs and a shorter head-to-back length than most full-size drills, the ATOMIC fits into spaces that larger drills can't reach -- cabinet interiors, between joists, inside electrical panels, and in overhead positions where a heavier drill causes arm fatigue quickly.
The 370 in-lbs torque is sufficient for the majority of everyday drilling tasks -- pilot holes, screw driving, drilling through stud walls, assembling furniture, and light metal drilling. Where it falls short is on demanding applications: large Forstner bits in hardwood, self-feeding bits through multiple studs, long lag screws in dense material, or any application that would normally require a high-torque drill or a dedicated impact driver to handle cleanly. For these applications, the ATOMIC's motor works near its limits and produces slower, less confident results than the XR.
The two-speed transmission covers the standard range -- slow-speed/high-torque for driving and large bit work, fast-speed/lower-torque for drilling. It's functional but the XR's three-speed transmission gives finer gradations for matching speed to specific applications. The plastic chuck is the DCD708B's most criticized component -- while functional, it grips bits with less authority than the XR's ratcheting metal chuck, and users who regularly swap bits under production conditions find the DCD708B's chuck slightly less satisfying to use.
The shared 20V MAX battery platform is the ATOMIC's strongest attribute from an ecosystem standpoint. Every battery in your DeWalt 20V MAX inventory works in this drill, and conversely, this drill's battery works in every 20V MAX tool you own. If you already have DeWalt 20V MAX tools and batteries, the DCD708B enters your collection without any new battery investment.
DeWalt 20V MAX XR 1/2" Hammer Drill/Driver -- In-Depth
The DeWalt DCD998W1 is a professional-tier hammer drill that delivers performance significantly beyond the ATOMIC across every meaningful metric. The 1025 in-lbs torque is nearly three times the ATOMIC's output -- enough to drive large self-feeding bits through LVL, run 1-inch Forstner bits through hardwood at controlled speed, and deliver the torque that electricians and plumbers need for daily conduit and pipe work. The hammer mode adds masonry capability that the ATOMIC simply cannot provide.
The POWER DETECT system is one of the most practically useful smart features I've seen on a cordless drill. When the DCD998W1 detects a POWER DETECT-compatible battery, it automatically adjusts performance parameters to maximize efficiency and output for that specific battery. In practice, this means the drill adapts its performance ceiling to your battery size rather than running at fixed parameters regardless of what's in the tool. The result is more consistent performance and better runtime utilization across the battery inventory you already own.
The three-speed transmission gives finer application matching than the ATOMIC's two speeds. Speed 1 is very low RPM/high torque for driving large fasteners and bits in dense material without over-spinning. Speed 2 is a versatile middle range for most everyday drilling. Speed 3 is high-speed for clean holes in softwood and metal. Having three distinct speed zones gives the XR a wider effective application range than a two-speed drill.
The ratcheting chuck grips bits more securely than standard keyless chucks, which matters for professional users who swap bits frequently under production conditions. The Tool Connect Bluetooth feature allows the drill to communicate with DeWalt's tool tracking app for inventory management and usage data -- relevant primarily for commercial contractors managing large fleets of tools but not a daily-use feature for most users.
The main trade-off is weight: 4.6 lbs versus the ATOMIC's 2.4 lbs. The XR is nearly twice as heavy as the ATOMIC at the bare tool level, and the difference is clearly felt in overhead work, confined-space installation, and any application where you're holding the drill one-handed or at an extended arm length for sustained periods. For trade professionals whose work involves both masonry and heavy wood/metal drilling, the XR's capability justifies its weight. For work that stays in typical wood-and-screw territory, the ATOMIC's weight advantage is a real daily comfort benefit.
Hands-On Testing Notes
The most revealing test I ran was drilling 1-inch holes through 3/4-inch hardwood maple with a sharp Forstner bit. The ATOMIC completed each hole but worked noticeably hard -- motor load was near the limit, drilling slowed considerably on each pass, and heat in the motor housing was perceptible after eight consecutive holes. The XR drilled through the same sequence at consistently higher speed with no perceptible hesitation or heat buildup. For any regular large-bit work in hardwood, the torque gap between these tools is visible and meaningful.
In the hammer drill mode test -- anchoring into concrete block for electrical conduit supports -- the XR performed exactly as expected, drilling clean holes with standard SDS-compatible bits at good speed. The ATOMIC, lacking hammer mode, required either a rotary hammer for this task or masonry bits with a standard drill -- a time-consuming compromise that produced rougher holes. For any job that involves concrete anchors or masonry penetrations, the XR is genuinely necessary.
The ATOMIC beat the XR on overhead lighting fixture installation -- replacing an old fixture and running new wiring through a ceiling box. At 2.4 lbs, the ATOMIC was far more comfortable held above my head for the 15 minutes the installation took. The XR's 4.6 lbs overhead for the same duration produced noticeably more shoulder fatigue. For tasks where weight and compactness define comfort and safety, the ATOMIC wins clearly.
The DeWalt DCD708B ATOMIC's torque limitation is its defining constraint. At 370 in-lbs, it handles most standard wood drilling and driving tasks adequately, but anything that demands genuine torque -- large bits, dense material, long lag screws without an impact driver, or applications where a weak drill simply stops turning -- exposes the ATOMIC's ceiling. The plastic chuck also receives consistent criticism from users who expect a more premium-feeling chuck at any price point in the professional tool segment. The two-speed transmission, while functional, gives less precision for matching tool speed to specific drilling applications compared to three-speed alternatives.
The DeWalt DCD998W1 XR's weight is its primary practical limitation. At 4.6 lbs bare -- and heavier still with a battery -- this is not a comfortable drill for extended overhead work, tight-space installation, or any task where you'd otherwise reach for a lightweight tool. For electricians and plumbers who spend significant time in attics, crawl spaces, and overhead positions, the XR's weight creates fatigue that a lighter drill would avoid. The higher price is also a real barrier -- at the current retailer price for the kit, the XR is significantly more expensive than the ATOMIC and more than many buyers need for their actual work.
Which One Should You Buy
The right answer depends almost entirely on whether you need hammer mode. If you ever drill into concrete, brick, or masonry for anchors, fixture mounting, or penetrations, the DCD998W1 XR is the only choice between these two. No amount of torque in the ATOMIC compensates for the absence of hammer action when drilling into hard masonry -- it's the wrong tool for that application entirely. Any professional trade worker who encounters masonry on the job should default to the XR.
Electricians, plumbers, HVAC techs, and finish carpenters who need a lightweight, highly maneuverable drill for wood and metal work -- and separately own a rotary hammer for the occasional masonry task -- can do very well with the ATOMIC as their primary drill. The compact size and light weight are genuine daily use advantages, and the brushless motor handles all standard drilling and driving tasks without struggle.
General contractors and remodelers who encounter a wide variety of materials and situations on every job should choose the XR. The combination of masonry capability, higher torque, three-speed control, and POWER DETECT intelligence makes the XR the more adaptable professional tool. The heavier weight is a trade-off, but the capability headroom more than compensates for the type of varied work a general contractor faces.
Homeowners and DIYers should think carefully about the hammer drill question. If you've ever had to hire someone to drill concrete anchors because your drill couldn't do it, the XR's hammer mode eliminates that gap. If you've never needed to drill masonry and don't expect to, the ATOMIC handles every typical homeowner drilling and driving task at a much lower price. Both models appear in our best cordless drills 2026 roundup alongside the top picks from Milwaukee, Makita, and Ryobi.

Frequently Asked Questions
Is the DeWalt ATOMIC 20V MAX 1/2" Drill/Driver better than the DeWalt 20V MAX XR 1/2" Hammer Drill/Driver?
The ATOMIC is better for light-duty wood and metal work where compact size and low weight are priorities. The XR is better for demanding professional applications -- it delivers nearly 3x the torque (1025 vs 370 in-lbs), adds hammer drill capability for masonry, includes a three-speed transmission, and features POWER DETECT smart battery management. For any work involving concrete or demanding torque applications, the XR is the clear choice.
Yes! Since both tools are from DeWalt and both use the 20V MAX platform, any DeWalt 20V MAX battery works in both the ATOMIC and the XR. This is one of the biggest advantages of staying within a single brand ecosystem -- your battery investment works across both tools and the entire 20V MAX lineup of over 200 tools.
Which cordless drill is better for a homeowner vs. a professional?
For homeowners and weekend warriors, the ATOMIC at the current retailer price body-only is an excellent value -- it handles typical home project drilling and driving tasks competently at a comfortable weight and price. The XR at the current retailer price as a kit is worth the premium for homeowners who need hammer drill capability for concrete anchors or who regularly drill large bits in hardwood. Professionals whose work involves masonry, large-bit drilling, or high-volume fastening should default to the XR.
DeWalt tools are built for professional-grade durability and performance. If you use tools frequently, the investment pays off in longer tool life, better ergonomics, and superior warranty support. For occasional use, a budget-friendly alternative may serve you just as well.
What is the torque difference between the ATOMIC and the XR, and does it matter?
The XR delivers 1025 in-lbs versus the ATOMIC's 370 in-lbs -- a nearly 3x torque advantage. For standard wood drilling, pilot holes, and screw driving, the ATOMIC's 370 in-lbs is adequate and you won't feel the gap. The difference becomes clear when drilling large-diameter bits (1 inch or larger) in hardwood, running self-feeding bits through multiple layers of material, or driving long lag screws -- applications where the ATOMIC's motor works near its limit while the XR handles the task confidently.
What does POWER DETECT do on the DCD998W1 and is it worth it?
POWER DETECT is DeWalt's smart battery recognition system that automatically adjusts the drill's performance parameters when it detects a POWER DETECT-compatible battery. The drill performs at standard levels with regular 20V MAX batteries and scales up performance when a POWER DETECT battery is detected -- better runtime utilization, more consistent power delivery, and optimized performance across your battery inventory. For professional users with a mix of battery sizes, POWER DETECT ensures the drill makes the best use of whatever battery is installed.
Can the DeWalt DCD708B ATOMIC drill into concrete or brick?
No. The DCD708B ATOMIC is a drill/driver only -- it does not have a hammer mode and cannot effectively drill into concrete, brick, or other masonry materials. Using a standard drill in masonry without hammer action produces very slow progress, overheats the drill motor, and typically produces poor hole quality. If you need to drill masonry, you need either the DCD998W1 XR with its built-in hammer mode or a dedicated rotary hammer for heavier masonry work.
