The DCD800’s handle leans slightly forward to orient the drill in a flat plane when drilling. The handle’s lean and head’s flat angle aren’t as aggressive as other drills, which remain flat when rolling your wrist forward and exerting additional pressure with your arm in line with the head.

A metal belt hook is included and can be mounted on either side of the base in one of the available slots, which can also be used for a third-party bit holder.

Otherwise, a rubber overmold strategically surrounds the grip for shock absorption and grip.

Lanyard compatible: Yes

The DCD805 has a familiar forward-leaning handle to orient the drill on the appropriate flat plane when drilling. However, the head angle uniquely slopes down minimally. Most drills either have a flat or upward-sloping head angle. In practice, the DCD805’s downward head angle means the drill isn’t held flat when rolling your wrist forward, which some users do when drilling aggressively.

Nearly all Dewalt drills include the same rubber overmold grip design, including the DCD805. The rubberized grip provides necessary shock absorption and grip under load.

There are two accessory slots on the base of the DCD805. These slots accept the all-metal belt hook in the box, or you can add third-party features, such as a bit holder.

Weight

Dewalt DCD800 On Scale

Bare weight (lbs): 2.84
Weight w/ 2Ah battery (lbs): 3.64
Weight w/ 4Ah battery (lbs): Not tested
Weight w/ 5Ah battery (lbs): 4.26

The DCD800 is moderately heavy for an 18V drill, weighing in at 2.84 lbs in its bare form. The bulky weight does lead to muscle fatigue, as we experienced at several points running repetitive tests.

We tested different battery configurations since the working weight can differ meaningfully from the bare tool weight. We recommend combining the DCD800 with Dewalt’s 20V Powerstack 1.7Ah battery, which weighs less, has a smaller footprint, and runs longer than Dewalt’s 20V Max 2Ah battery, a solid alternative for a svelte setup.

Pair the DCD800 with Dewalt’s 20V Max XR 5Ah battery for a longer run time and improved drilling performance if weight is less of a concern.

Bare weight (lbs): 3.00
Weight w/ 2Ah battery (lbs): 3.80
Weight w/ 4Ah battery (lbs): Not tested
Weight w/ 5Ah battery (lbs): 4.42

The DCD805 is a heavy hammer drill, weighing 3.00 lbs in its bare form. You can comfortably hang it from a sturdy work belt by the belt hook. But it’s not light enough to comfortably drop in your jeans pocket for portability.

Many professionals will use this drill with a high Ah-capacity battery. When kitting it out with a 20V Max XR 5Ah battery, the setup weighs 4.42 lbs. We ran into several instances throughout testing where hand fatigue set in, which is expected in this brute force class.

To get sufficient performance in as lightweight a setup as possible, we recommend combining the DCD805 with Dewalt’s 20V Powerstack 1.7Ah battery, which weighs less, has a smaller footprint, and runs longer than Dewalt’s 20V Max 2Ah battery, a solid alternative for a svelte setup.

Max width (in.): 3.125
Chuck to back length (in.): 6.375
Base length (in.): 4.500
Base width (in.): 3.125

The DCD800’s footprint is a tale of two stories, but it is compact in the areas that matter most. It is one of the shortest 18V drills in our test fleet from tip to tail and shorter than some less powerful and supposedly “compact” 12V drills. The tip-to-tail length is essential since it determines how easily it squeezes into tight areas, as we test below in our clearance tests.

However, the DCD800 is tall, and the head size casts a wide shadow.

The DCD805 is moderately large when measured in many of its dimensions. To fit the hammering mechanism, the head is wider and longer than its non-hammer drill sister, the Dewalt 20V Max XR DCD800. The increased head size also adds length from tip to tail, though it’s not an overly tall hammer drill.

There is only a single action mode on the DCD800. The drill mode disengages the clutch to offer unfettered torque output for boring wide holes and driving big fasteners. Unlike the sister Dewalt 20V Max XR DCD805 Hammer Drill, there is no hammer functionality.

One feature Dewalt should consider adding is kickback control technology, which some of the best Milwaukee drills include. The DCD800 is exceptionally powerful, increasing the risk of wrist injuries when the drill bit binds up.

Advertised blows per min. (speed 1): Not advertised
Variable speed trigger: Yes
Kickback control technology: No
Trigger draw length (in.): 0.250

There are two drilling action modes. The drill mode disengages the chuck for the highest torque output, which is ideal for boring big holes and driving lag bolts and structural fasteners.

The hammer drill mode operates in the same manner but adds in a hammer that impacts at a rate of 34,000.00 blows per minute, which is among the highest in our test fleet. We tested the hammer’s effectiveness in our drilling speed test below to understand the speed improvements offered.

One area for improvement is including some kickback control technology to enhance safety when since an auxiliary arm isn’t included. The Milwaukee M18 Fuel 2904-20 Hammer Drill includes kickback control technology.

Clutch & speed settings

Dewalt DCD800 Clutch & Speed

Speed settings: 2
Clutch settings: 15

The two-speed transmission can run the DCD800 in the high or low setting in the single action mode and any of the 15 clutch settings. As with all drills, setting the drill to the low setting in the drill mode generates the maximum torque output.

While 15 clutch settings are fewer than some drills, it is enough to precisely tune the torque output to avoid stripping screws and finishing with the proper recess.

Chuck

Dewalt DCD800 Chuck Closeup

Chuck size: 1/2″
Chuck sleeve material: Knurled metal

The all-metal ratcheting chuck offers better durability and build quality than drills with hybrid metal and plastic chucks. The metal knurled chuck sleeve is perfectly machined to provide the right amount of friction when locking in drill bits with your hand. We didn’t encounter issues with the three jaws loosening throughout our testing, making it completely frustration-free.

Chuck

The DCD805 is a flagship hammer drill, so we expected it to have a premium chuck. It did not disappoint. The all-metal chuck locked onto bits and didn’t inadvertently loosen at any point throughout our lab tests. The metal knurling on the chuck sleeve also provides the right amount of friction when ratcheting the chuck by hand, which is helpful for quickly and confidently inserting drill bits.

Auxiliary arm

Auxiliary arm: No

The DCD800 does not include an auxiliary handle, which is a letdown for such a powerful drill. The Milwaukee M18 2904-20 Hammer Drill and Makita 18V LXT XPH14Z Hammer Drill include auxiliary arms and are powerful.

Auxiliary arm

Auxiliary arm: No

The DCD805 is a powerful drill that should include a detachable auxiliary arm in the box to improve user safety when the drill binds up. The Makita 18V LXT XPH14Z Hammer Drill and Milwaukee M18 Fuel 2904-20 Hammer Drill are powerful and include auxiliary arms.

Drilling speed

Drilling speed average time (drill mode, sec.): 2.3
Drilling speed total time (hammer mode, sec.): N/A
Drilling speed average time (hammer mode, sec.): N/A
Hammer mode speed improvement: N/A

The DCD800 drills incredibly fast when under heavy load. It averaged 2.3 seconds per 1/2-inch hole bored in our drilling speed tests designed to explore each drill’s upper range. Critically for a contractor-grade drill, it sustains high RPMs throughout the hole depth and blasts out chips to avoid bogging down.

The DCD800 also chewed through other drilling tasks we threw at it, including boring narrower and wider holes with various spade and forstner bits. We needed to drop a gear for additional torque in a few instances.

But consider that the DCD800 isn’t ideal for the average homeowner who rarely pushes any power tool to its limits and could risk injury if not used correctly. There are more compact, powerful options that are more user-friendly, such as the Dewalt 20V Atomic DCD799 Hammer Drill.

Drilling speed average time (drill mode, sec.): 2.0
Drilling speed total time (hammer mode, sec.): 7.2
Drilling speed average time (hammer mode, sec.): 1.4
Hammer mode speed improvement: 28.7%

The DCD805 is an impressively fast drill that sustains high RPMs under demanding drilling loads. The DCD805 completed our drilling speed test blazingly fast in 10.1 seconds in the standard drill mode.

The results are even rosier in the hammer drill mode, which brought the time down to 7.2 seconds to bore five 1/2-inch holes. That’s a speed improvement of 28.7%, which is high compared to other hammer drills in our test fleet.

We further tested drilling wider and narrower gauge holes using a mix of forstner and spade bits. The DCD805 finished most of these tests without needing to downshift a gear for additional torque, which is rare for models we’ve tested.

While the power output is impressive and fun to experience, the DCD805 is arguably overpowered for most homeowners, who don’t push tools to their limits and may be more prone to wrist injuries when not using it appropriately. Consider the Dewalt 20V Atomic DCD799 Hammer Drill if you want a more user-friendly drill for around the home.

Driving speed

GRK total driving time forward (sec.): 6.5
GRK average driving time forward (sec.): 1.3
GRK total driving time reverse (sec.): 6.0

The DCD800 is blazingly fast when driving structural screws. It took the podium position for driving speed in our Summer 2023 test fleet, averaging 1.3 seconds per fastener, not accounting for downtime between finishing each GRK RSS fastener.

We also tested driving several wider gauge and longer lag bolts into stacked dimensional 2x6s. The DCD800 similarly breezed through each scenario without dropping to the low setting for additional torque.

Unsurprisingly, the DCD805 is also incredibly fast driving big fasteners. It delivered one of the swiftest results in our Summer 2023 drill test fleet, finishing five GRK RSS 5 1/8-inch fasteners in only 7.1 seconds, not counting down time between each screw.

We further tested the DCD805 by driving several longer and wider gauge lag bolts into stacked 2x6s. We didn’t run into a scenario where we needed to drop to the low setting for added torque to finish the job, rare for most drills.

Battery lineup

Dewalt 20V Max Battery Lineup

Dewalt offers 1.5Ah, 2Ah, 3Ah, 4Ah, 5Ah, 8Ah, 10Ah, and 12Ah batteries in its 20V Max lineup. Upgrading to the higher Ah options increases battery run time and improves drilling performance, though we’ve not tested all of these batteries to understand the cost tradeoffs.

Buying at least two batteries is best so you don’t miss a beat when draining one battery. We recommend purchasing a Dewalt 20V Max 2Ah and a Dewalt 20V Max XR 5Ah battery for most Dewalt 20V drill setups for a good balance of performance, price, and size.

Dewalt’s 20V Powerstack batteries may be a smart buying choice for some users. Dewalt advertises improved drilling performance, longer battery run time, and more battery cycles out of its 20V Powerstack 1.7Ah and 5Ah batteries than its standard 20V Max batteries. We plan on testing the performance differences to understand the cost tradeoffs.

When testing the RPM output on a contact tachometer, we found that the DCD800 matches Dewalt’s lofty advertised claims. The DCD800 generated 2,046.0 RPMs in our lab on the high setting and 648.0 RPMs on the low setting. As our drilling and driving tests demonstrated, the DCD800 is powerful enough to sustain high RPMs under load.

The DCD805’s drilling and driving speed performance directly relates to the high RPM output. In all the action modes and transmission settings, we tested the RPM performance with a contact tachometer in a no-load scenario.

While no-load RPM output doesn’t tell the whole story of how a drill performs under load, our speed testing results confirm that the DCD805 has the muscle to sustain RPMs at a higher rate than many hammer drills under load.

Drilling clearance

Min. interior width clearance (in.): 7.825
Min. top edge clearance (in.): 1.500
Min. interior 45-deg. clearance (in.): 6.500

We noted in the Footprint section that the DCD800’s size is a tale of two stories. Let’s focus first on where the size positively impacts its performance in obstructed areas. Since the tip-to-tail length is short, the DCD800 sandwiches well between two vertical obstructions and squeezes into tight corners at an angle.

However, since the head is moderately bulky, the DCD800 doesn’t perform well in our top edge clearance test, designed to understand how easily a drill fits under shelves and in other situations when obstructed from above.

The DCD805’s moderately large footprint didn’t help it shine in our clearance tests, designed to understand the obstructed spaces and tight areas each drill fits into. Notably, the moderately long tip-to-tail length and bulky head limit the spaces it fits into, including scenarios such as drilling under shelves and fitting into restricted corners.
