How To Choose The Best Cordless Drill Heavy Duty

Before you buy, you need to separate the numbers that matter from the ones that just look impressive on the box. For a heavy-duty drill, three things decide whether it will handle your projects: torque, the motor type, and the battery system you are already invested in.

Torque Is the Real Story

The torque rating, measured in inch-pounds (in-lbs), tells you how much twisting force the drill can deliver. Higher torque means the drill can turn large auger bits and hole saws through dense material without stalling. A basic drill might offer 350 in-lbs, while the heavy hitters in this list push past 1,100 in-lbs, with the top performer reaching 2,100 in-lbs. Max RPM (rotations per minute) matters more for driving screws quickly than for power, so do not fixate on it.

Brushless vs. Brushed Motors

A brushless motor uses electronic controls instead of carbon brushes that physically rub against the spinning part. That design means less heat, more runtime per charge, and a longer working life. Every pick on this list uses a brushless motor, which is the defining feature of the modern heavy-duty class.

Hammer Mode vs. Standard Drilling

A hammer drill adds a pulsing, hammering action that helps bits chew through brick, concrete, and masonry. If you plan to mount TVs on block walls or anchor into a concrete foundation, you want a hammer drill. If your work is mostly wood, metal, and drywall, a standard drill/driver will do, though a hammer drill can still be used with the hammer function switched off.

In‑Depth Reviews

★ Best Overall

1. DEWALT 20V MAX XR Cordless Drill/Driver (DCD800B)

Our pick — over 4.5★ from 800+ verified ratings; the strongest balance of quality and price.

3.2 lbs0-2,000 rpm

The compact pro that punches above its size class without wearing out your arm.

The DCD800B is the pick for DEWALT 20V MAX battery owners who want a compact pro drill with up to 40% more power than the DCD791B. It delivers up to 40% more unit watts out (UWO, a measure of a drill’s overall power output) than the older DCD791B when paired with a DCB205 or DCBP034 POWERSTACK battery. Owners mention it “handled 22 3.5″ holes in hemlock with hole saw” — a serious test that shows this is not a toy.

At 3.2 pounds, it is noticeably lighter than the BLACK+DECKER hammer drill above, and its compact 6.37-inch head is half an inch shorter than the DCD791, which helps in tight spots like inside cabinets or between studs. The 1/2-inch metal ratcheting chuck holds bits securely, and the 3-position LED with up to 70 lumens includes a spotlight mode with a 20-minute auto-shutoff for extended work in dark attics or crawl spaces.

You get precise control for both delicate fastening and high-speed drilling thanks to the 2-speed transmission (0-650/0-2,000 rpm) with a variable trigger. Some owners find the metal clutch stiff and note the placement is awkward for smaller hands, but the overwhelming consensus is that this is the best drill they have ever owned, with quality being the single most praised aspect.

What wins owners over

  • Exceptional power-to-weight ratio at 3.2 lbs
  • Compact 6.37-in head reaches tight spaces
  • Bright pivoting LED with 70 lumens and spotlight mode
  • Kickback control prevents wrist injury on bit jams

The honest trade-offs

  • Bare tool only — battery and charger sold separately
  • Stiff metal clutch can be awkward for small hands
  • Premium price point for a tool-only purchase

Reach for this if: you want a pro-level daily driver that is easy to control and already run DEWALT batteries.

Think twice if: you need a hammer function for concrete — this is a standard drill, so grab the DCD806B below for masonry.

Budget Champion

2. BLACK+DECKER 20V MAX POWERCONNECT Hammer Drill Kit (BLD783D1)

2Ah Battery30,000 BPM

The weekend warrior’s concrete-friendly kit that includes everything to start.

The BLD783D1 is the value pick for home users who need hammer action for masonry without the pro price tag. This kit arrives complete with the drill, a 2Ah battery, a charger, a belt clip, a magnetic bit holder, and a double-ended screwdriver bit, so you can start working immediately. It produces 30,000 beats per minute (BPM) of hammer action for drilling into brick and concrete, and spins up to 1,900 rpm for standard drilling.

On a single charge, customers note the 2Ah battery “drove ~300 screws/charge (650 total, 2 charges)” — solid endurance for a budget tool. The 1/2-inch keyless metal chuck makes bit changes quick, and the 10 clutch positions plus variable trigger give you speed control. The built-in LED and battery state-of-charge indicator are features usually reserved for pricier models.

Enthusiasts note it drills pilot holes for tapcons in concrete quickly and efficiently, with setup graphics that are self-explanatory enough to skip the manual. The trade-off is that the included charger is slow, and the forward/reverse button placement takes some getting used to depending on your grip.

Smart kit for starters: everything you need in one box, including a battery gauge and magnetic bit holder.

Keep expectations in check: not built for daily contractor abuse, but a reliable partner for weekend projects and light masonry.

High-Torque Value

3. DongCheng 20V MAX Brushless Hammer Drill (DCJZ2090i)

796 in-lbs4.0Ah Battery

A torque monster that spins faster than drills costing twice as much.

The DongCheng DCJZ2090i is for remodelers and DIYers who want 796 in-lbs of torque and anti-kickback protection on a budget. It generates 796 in-lbs (90 Nm) of max torque, spins up to 2,200 rpm — a 16% higher top speed than the BLACK+DECKER’s 1,900 rpm — and hits 34,500 BPM in hammer mode for concrete and brick. The 3-in-1 design switches between hammer, drill, and driver modes with a simple flick.

The standout safety feature is the gyroscope anti-kickback system. A built-in gyroscope sensor detects sudden bit binding and shuts off the motor in milliseconds, preventing the tool from violently twisting your wrist when you hit a knot in wood or rebar in concrete. The 21-position clutch lets you dial in torque precisely so you do not strip screws in delicate cabinet work.

The 1/2-inch all-metal ratcheting chuck grips bits firmly, and the kit ships with a 4.0Ah battery, charger, tool bag, and warranty card. Reviewers point out it is “really good a little bit heavy but well balanced very powerful.” At 4.1 pounds with the battery, it is identical in weight to the BLACK+DECKER but delivers significantly more torque per pound. The main complaint is fatigue during overhead work, so it is best for remodeling projects where you can brace the tool.

Raw power, fair price: the anti-kickback gyroscope alone is worth it if you drill into dense material regularly.

Heft is the cost: tiring overhead work — pair it with the auxiliary handle for two-handed control on big holes.

Masonry Muscle

4. NANWEI Hammer Drill with 2x 4.0Ah Batteries (NW-D8217C)

1,100 in-lbs2x 4.0Ah

A brick-house owner’s best friend with enough twist for steel plate.

The NANWEI NW-D8217C is the pick for homeowners with masonry-heavy projects who need 1,100 in-lbs of torque. Its 1,100 in-lbs (120 N·m) of max torque is significantly higher than the DongCheng’s 796 in-lbs, meaning it can power through thick masonry and tough steel with less effort. The brushless motor delivers 80% higher power output with 60% lower energy consumption than traditional copper motors, so you get more work per charge.

The kit includes two 4.0Ah batteries, a fast charger, and a tool storage box. Having a spare battery means you can keep working while one charges, and shoppers say drilling through red brick and even granite rock with impressive results. The 2-speed transmission (0-450/0-1,750 rpm) with a 20+1+1 torque-adjustable clutch gives you precision control for screwdriving while reserving raw power for drilling.

Drilling capacity reaches 1/2 inch in concrete and steel, and 4 inches in wood, making it a versatile 3-in-1 tool for drilling, hammer drilling, and screwdriving. Anti-kickback protection automatically detects sudden bit jams to prevent wrist strain. The notable caveat is that the batteries are exclusively designed for NANWEI products and are not compatible with other brands, so you are committing to this ecosystem. Owners with Makita batteries note the tool feels at home with that platform’s ergonomics.

Where it shines

  • High 1,100 in-lbs torque for masonry and steel
  • Two 4.0Ah batteries keep you working all day
  • 4-inch wood drilling capacity handles large auger bits
  • Solidly built with a quality storage case

What to know

  • Batteries are locked to the NANWEI brand only
  • Lower top speed of 1,750 rpm vs. competitors
  • Limited track record compared to legacy brands

Best if: you need serious masonry power and want two batteries in the box.

Skip if: you are already invested in another brand’s battery system and want one charger for everything.

V20 System Entry

5. CRAFTSMAN V20 Cordless Drill/Driver Kit (CMCD710C1)

350 UWO1.3Ah Battery

A solid V20 family starter that grows with your tool collection.

The CMCD710C1 is the gateway into the CRAFTSMAN V20 system, which spans dozens of tools sharing the same batteries. The brushless motor produces 350 unit watts out (UWO) for a variety of jobsite applications, and it does so with up to 25% more runtime and improved durability over brushed versions. The 2-speed gearbox offers 0-600/0-1,900 rpm speeds.

The kit includes a 1.3Ah battery and a charger that provides a 60-minute or less charge time. The 1/2-inch ratcheting chuck provides improved bit retention, and the built-in LED light improves visibility in dark work areas. Owners who upgraded from an entry-level Craftsman drill report it holds bits well and delivers real power, with one noting it is “alot better then some brands” after several years of use.

At 5.1 pounds, this is the heaviest drill on this list by a clear margin — it feels heavier in the hand than the DEWALT DCD800B’s 3.2 pounds. Some buyers report negative feedback on battery life, so expect to buy a spare battery for longer sessions. The 3-year limited warranty adds confidence, and the VERSATRACK wall organization compatibility is a nice touch for keeping your shop tidy. This one suits those already owning V20 tools or starting fresh on a budget.

Family-first buying: buy into the V20 ecosystem and this drill becomes one of many tools on one battery platform.

Heft and runtime: bring a second battery if you plan long sessions — the included 1.3Ah pack runs out quickly.

Lightweight Power

6. GREENWORKS 24V 1/2″ Brushless Cordless Drill (800 In-lbs)

2.81 lbs800 in-lbs

The featherweight 24V drill that doubles as a phone power bank.

The GREENWORKS 24V drill is the pick for anyone who wants 800 in-lbs of torque in a featherweight 2.81-lb body. At just 2.81 pounds, it is the lightest drill on this list — comfortably lighter than the 4.1-pound DongCheng and BLACK+DECKER — and that makes all-day overhead work genuinely easier. It delivers 800 in-lbs of torque from a 24V brushless motor, which the maker claims offers 2X more torque and 35% longer runtime compared to 20V competitors.

The signature feature is the USB-C battery system. The 4.0Ah (24,000mAh) battery charges via a 65W rapid charger and can also power your phone, with enough juice for 4 charges of an iPhone 15, 3.5 charges of a Galaxy S23, or 2.2 charges of an iPad mini 6. That two-way USB-C port means the battery is both a drill power source and a portable power bank, a genuinely useful twist for remote work sites.

You get precise torque control from the 2-speed gearbox (0-500/0-2,100 rpm) with a 21-position clutch, and the 1/2-inch keyless ratcheting metal chuck makes bit changes fast. Owners mention superb battery life and sturdy construction, with one using it daily for building construction on metal and wood. The 35% more compact design helps in tight spaces, and the 3-year limited warranty with lifetime support covers you long-term. This drill works with over 150 Greenworks 24V tools if you want to grow the system.

Why it stands out

  • Ultra-light 2.81 lbs reduces fatigue
  • USB-C battery charges devices like a power bank
  • 800 in-lbs torque in a 24V package
  • 65W rapid charging gets you back to work fast

Consider first

  • 24V battery is not shared with 20V tool families
  • Newer system with fewer third-party accessories

Grab this if: you want maximum power per pound and like the idea of a battery that charges your phone on site.

Look elsewhere if: you already own a stable of 20V tools and want one battery platform for everything.

Concrete Crusher

7. DEWALT 20V MAX XR Brushless Hammer Drill (DCD806B)

70 Lumens LED0-2,000 rpm

The hammer drill that chews through brick and concrete like butter.

The DCD806B is DEWALT’s most powerful 20V MAX 2-speed hammer drill, rated up to 109% more powerful than standard models, and it is the one to reach for when your project involves masonry. Owners describe it as drilling “through brick and concrete like butter,” which is exactly the kind of real-world performance you want when anchoring into a foundation wall. The 1/2-inch metal ratcheting chuck provides secure bit retention under high-torque loads.

Safety is a major focus here. The ANTI-ROTATION System senses excessive rotational motion, such as a bit catching on rebar, and shuts the tool down instantly to protect your wrist. A red LED indicator illuminates when the system engages so you know it is working. The high-speed transmission with variable speed trigger offers 2 settings (0-650/0-2,000 rpm) for control across applications.

The adjustable 3-position LED provides 70 lumens with auto-shutoff, and the tool is TOOL CONNECT CHIP READY, meaning you can pair it with a DEWALT Site Manager app via a chip sold separately to track the tool’s location. At 3.5 pounds, it is balanced and comfortable for a hammer drill. Owners consistently praise the quality and power, noting it is a genuine upgrade over older models with better speed, brightness, and anti-kickback protection. This is a tool-only purchase, so you need DEWALT batteries and a charger.

The masonry standard: quality is the most-praised aspect, with power close behind — a combination that makes this the go-to for installation work.

Bring your own battery: tool-only means existing DEWALT 20V MAX owners get the best value here.

ONE+ HP Upgrade

8. RYOBI ONE+ HP 18V Brushless Drill/Driver Kit (PBLDD01K1)

2,100 rpm2.0Ah Battery

The HP brushless upgrade that RYOBI loyalists have been waiting for.

The PBLDD01K1 is for RYOBI ONE+ owners who want the more powerful HP (High Performance) brushless line. This kit includes the drill with a 2.0Ah HIGH PERFORMANCE battery, which holds a longer charge than standard packs. The 1/2-inch metal chuck and 2,100 rpm top speed put it in the same performance class as drills from more expensive brands.

Owners who upgraded from the non-HP version of this drill are emphatic that this is the superior tool, describing it as a “great drill especially for the money.” One household bought it as a gift and ended up becoming a “two-drill household” once they found the original — proof of how quickly this becomes the go-to tool. The brushless motor runs cooler and more efficiently than brushed versions, which extends both runtime and motor life.

At 5.1 pounds, this matches the CRAFTSMAN as the heaviest option here, which is noticeable during extended use. The real value, though, is the ecosystem: RYOBI ONE+ has one of the largest tool lineups in the industry, all sharing the same battery platform. If you already own RYOBI tools, this HP drill is a straightforward upgrade path without buying into a new battery system.

The upgrade case

  • Shares batteries with the huge ONE+ tool family
  • HP battery holds charge longer than standard packs
  • 2,100 rpm top speed for fast fastening

Weigh this

  • 5.1 lbs makes it one of the heaviest picks
  • Not a hammer drill — no masonry mode

Pick this if: you are a RYOBI ONE+ user who wants a heavy-duty brushless driver without switching platforms.

Pass if: you need hammer action for concrete or want the lightest possible tool for overhead work.

Combo Value

9. Metabo HPT 18V Brushless Drill & Impact Driver Combo (KC18DEXQB)

1,549 in-lbs2 Batteries

Two pro-grade tools that weigh less than one competitor’s drill.

The KC18DEXQB combo kit is the answer for anyone who needs both a drill and an impact driver — the two tools that handle 90% of jobsite fastening and drilling. You get the 18V Brushless 1/2″ Driver Drill (DS18DEX) delivering up to 620 in-lbs of torque, plus the 18V Power Impact Driver (WH18DEX) with a hefty 1,549 in-lbs of turning torque for driving long screws and lag bolts. The kit includes two lithium-ion batteries with charge indicators, a charger, a Phillips bit, and a carrying bag.

The defining feature here is weight. Both tools are under 3 lbs without the battery, with the Driver Drill at 6.1 inches in length and the Impact Driver even more compact at 4.72 inches. That makes this combo among the lightest setups available, reducing fatigue during long days and letting you work in tight spaces other drills cannot reach. Owners who switched from other brands describe the feel as “far superior in quality and hand-feel.”

Safety features include Reactive Force Control (RFC) on the drill, which shuts down the tool if the bit binds suddenly. The impact driver dropped from a ladder at about 8 feet survived with hardly a scratch, according to one owner, a strong sign of build quality. The warranty is exceptional: Lifetime Tool Body, 2-Year Battery, and 1-Year Charger coverage. The 2-speed transmission reaches 2,000 rpm, and both tools feature LED lights for dark workspaces.

What you get

  • Drill + impact driver in one kit, both under 3 lbs
  • 1,549 in-lbs impact torque for serious fastening
  • Lifetime tool body warranty
  • Compact 4.72-in impact driver fits tight spots

Watch for

  • Mixed feedback on drill chuck holding bits
  • Two separate tools means more to carry

Best for: contractors and serious DIYers who want a complete fastening setup that is easy on the arms.

Consider the catch: quality control on the chuck draws mixed reviews — inspect it early and use the warranty if bits slip.

Pro Corded-Style

10. Bosch Professional BITURBO GSR 18V-150 C

150 NmKickBack Control

Corded-tool power in a cordless body, engineered for professionals.

The Bosch GSR 18V-150 C is the premium choice for professionals who refuse to compromise on power. Its brushless high-performance motor, combined with ProCORE18V batteries (at least 5.5 Ah), delivers maximum torque of 150 Nm — comparable to corded tools. This is the drill that does not slow down, whether you are mixing paint, drilling 20mm wood bits through 80cm boards, or driving drywall screws all day. Owners describe it as a tool that does not “slow for anything.”

The standout innovations here are Electronic Angle Detection and switchable KickBack Control. The angle detection function helps you estimate drilling angle with long bits, while the anti-torque system shuts the tool down on jams to keep it safe and easy to handle. These features make it exceptionally controlled for a tool with this much power. The auxiliary handle is included, which is essential for two-handed control on big holes.

The kit includes the drill, auxiliary handle, L-BOXX inlay, and L-BOXX 136 case for organized storage. It works with the Bosch Professional 18V System and the multi-brand AMPShare battery alliance. The weight is significant, especially with 5.5Ah or 8Ah ProCore batteries, so this is not a one-handed tool. Note that this is a parallel import, so the model number, accessories, packaging, and warranty coverage may differ from US-official units — something to weigh if warranty support is critical to you.

Pro-level strengths

  • 150 Nm torque rivals corded drills
  • Electronic angle detection for precise angled drilling
  • KickBack Control prevents wrist injury
  • AMPShare compatible with other pro brands

Pro-level costs

  • Heavy, especially with large ProCore batteries
  • Parallel import may affect warranty coverage
  • Batteries and charger sold separately

For the professional: if you need corded-level output and precision angle control, this is the ultimate cordless driver.

Not for casual users: the weight and premium cost only make sense if you use it daily for demanding work.

Understanding the Specs

Torque (in-lbs vs. Nm)

Torque is the twisting force that determines whether a drill stalls in tough material. It is measured in inch-pounds (in-lbs) or Newton-meters (Nm), where 1 Nm equals roughly 8.85 in-lbs. A heavy-duty drill should offer at least 700 in-lbs (about 80 Nm); the top performers here push past 1,100 in-lbs, and the DEWALT DCD1007 reaches a massive 2,100 in-lbs. Higher torque lets you use larger auger bits and hole saws without the motor bogging down.

Brushless Motor

A brushless motor replaces the carbon brushes that physically rub against the spinning armature in older brushed motors. That difference means less friction, less heat, and more efficient power delivery. For you, that translates to roughly 25-35% more runtime per charge depending on the model, plus a longer working life since there are no brushes to wear out. Every drill on this list is brushless, which is the baseline for the heavy-duty class.

Hammer Action (BPM)

Hammer drills add a pulsing, forward-pounding action measured in beats per minute (BPM). This hammering helps masonry bits chew through brick, concrete, and block. Models like the BLACK+DECKER hit 30,000 BPM and the DongCheng reaches 34,500 BPM, which is enough for drilling anchor holes in concrete. A standard drill without hammer mode cannot do masonry work, so if you plan to mount anything on concrete, prioritize this feature.

Chuck Quality

The chuck is the part that grips your drill bit, and it matters more than most buyers realize. A 1/2-inch metal ratcheting chuck, found on most picks here, holds bits firmly and resists slipping under high torque. Lower-end drills use plastic chucks or smaller 3/8-inch chucks that struggle with larger bits. If you plan to use hole saws or auger bits, a metal 1/2-inch chuck is essential to prevent bit slippage at speed.

FAQ

What is the difference between a drill driver and a hammer drill?
A drill driver spins a chuck to drill holes and drive screws, while a hammer drill adds a pulsing hammer action that helps bits break through masonry. The hammer mode delivers rapid forward impacts (measured in beats per minute, or BPM) that crack concrete and brick as the bit spins. Most hammer drills, like the BLACK+DECKER BLD783D1, let you switch the hammer function off so the tool works as a regular drill for wood and metal.
How much torque do I really need in a heavy duty drill?
For serious work like driving large screws, using hole saws, or drilling into concrete, look for at least 700 in-lbs of torque. The DongCheng offers 796 in-lbs, the NANWEI delivers 1,100 in-lbs, and the DEWALT DCD1007 tops out at 2,100 in-lbs. If you mostly do light home repairs like hanging shelves, a 350-500 in-lbs drill like the CRAFTSMAN will suffice, but a heavy-duty drill gives you headroom for tougher jobs without stalling.
Can I use a brushless drill with my existing batteries from another brand?
No. Batteries are brand-specific and often model-specific. The NANWEI batteries are exclusively designed for NANWEI products and cannot be charged with other chargers. The GREENWORKS 24V battery works only with Greenworks 24V tools. Some brands share platforms across their own lineups, like DEWALT 20V MAX batteries fitting all DEWALT 20V tools, but you cannot mix brands. Check the compatible device list before buying to avoid purchasing a drill that doesnot work with batteries you already own.
Is a heavier drill always more powerful?
Not anymore. Modern brushless motors deliver more power in a lighter package. The GREENWORKS 24V produces 800 in-lbs of torque at just 2.81 pounds, while the CRAFTSMAN makes 350 UWO at 5.1 pounds. Weight now comes more from battery size and metal components than from motor mass. A heavier drill can help with control during big hole saw work, but it is not a reliable indicator of power.
What does anti-kickback protection actually do?
Anti-kickback protection, also called anti-rotation, uses sensors to detect when a drill bit suddenly binds or jams in the material. When that happens, the tool shuts off the motor in milliseconds before the body of the drill can violently twist your wrist. The DongCheng uses a gyroscope sensor for this, while DEWALT calls it the ANTI-ROTATION System. It is a genuinely useful safety feature when drilling into dense material like concrete or knotty wood where sudden jams are common.
How long does a 4.0Ah battery last in a heavy duty drill?
It depends heavily on the task. Driving screws is light work — the BLACK+DECKER’s 2Ah battery drove about 300 screws per charge. Drilling large holes in concrete or using a hole saw drains power much faster. The DEWALT DCD1007 with its 8Ah battery is rated for up to 275 holes per charge, while the DEWALT DCD806B makes up to 175 holes per charge. For all-day work, a kit with two batteries, like the NANWEI, lets you swap packs while one charges.
Can a cordless drill really replace a corded drill for heavy work?
For most jobs, yes. Modern brushless cordless drills like the Bosch GSR 18V-150 C deliver 150 Nm of torque, which the maker states is comparable to corded tools. The DEWALT DCD1007 at 2,100 in-lbs can power through large-diameter holes in metal and concrete. The main cordless compromise is runtime — a corded drill never runs out of power, while cordless batteries eventually need recharging. If you have spare batteries, cordless is now the practical choice for nearly everything.
What is the difference between a keyed and keyless chuck?
A keyless chuck lets you tighten and release bits by hand, usually with one hand, which makes quick bit changes fast and easy. A keyed chuck requires a separate metal key to tighten and loosen, offering a firmer grip under extreme torque but slowing you down. All the heavy-duty drills on this list use keyless 1/2-inch metal ratcheting chucks, which provide secure bit retention while keeping changes quick. Metal chucks hold bits better than plastic ones under high torque.
Is the DEWALT DCD800B worth it if I already own a standard drill?
It depends on what your standard drill cannot do. The DCD800B is a tool-only purchase, so you need DEWALT 20V MAX batteries and a charger already. If your current drill struggles with hole saws, large auger bits, or long fastening sessions, the DCD800B’s up to 40% more unit watts out versus the older DCD791B will be a meaningful upgrade. If your current drill handles your projects fine, the main gains would be the compact 6.37-inch head and the bright 70-lumen LED. It is not a hammer drill, so masonry work still requires the DCD806B.
Does every hammer drill drill into concrete equally well?
No. Hammer drills vary significantly in their hammer action and torque. The NANWEI produces 1,100 in-lbs of torque and its customers note drilling through red brick and granite rock. The DEWALT DCD806B is rated up to 109% more powerful than standard models, with owners saying it goes through brick and concrete like butter. The BLACK+DECKER is a budget option that handles pilot holes for tapcons in concrete, but its lower torque means slower progress in dense material. If concrete is your primary material, prioritize torque over speed ratings.

Final Thoughts: The Verdict

For the majority of shoppers, the cordless drill heavy duty winner is the DEWALT DCD800B because it delivers pro-level power in a compact 3.2-pound body that is easy to control. If you already own DEWALT batteries, it is the obvious daily driver. For masonry work at a friendlier price, the BLACK+DECKER BLD783D1 kit includes everything you need to start drilling into concrete immediately. And for maximum torque with battery life measured in weekends, the DEWALT DCD1007WW1 with its 2,100 in-lbs and 8Ah battery is the one to reach for.
