Dewalt 12V Xtreme DCD706 Hammer Drill Review

Dewalt DCD706 Angle 5

Quick take

The Dewalt 12V Xtreme DCD706 Hammer Drill is a solid tool for homeowners and woodworkers, where size and weight are more important than brute force power. It is compact, nimble, and exceptionally lightweight, rare features for a hammer drill. It also includes a brushless motor and a long tool and battery warranty. The primary downsides are the performance in demanding tasks, such as drilling 1/2-inch and wider holes and driving structural screws. The DCD706 finishes heavy-duty jobs in a pinch. It just doesn’t do so quickly. But most weekend warriors don’t demand power. Agility, weight, and performance in less demanding tasks are critical, all defining the DCD706.

Lab results

Drilling speed

Drilling speed total time (drill mode, sec.): 25.6
Drilling speed average time (drill mode, sec.): 5.1
Drilling speed total time (hammer mode, sec.): 20.9
Drilling speed average time (hammer mode, sec.): 4.2
Hammer mode speed improvement: 18.4%

One potential downside is the DCD706’s drilling speed. This drill completed our heavy-duty drilling speed test in 25.6 seconds, one of our slower results. The included hammer mode speeds up the process when drilling masonry or thick lumber. However, we don’t recommend the DCD706 if you frequently bore 1/2-inch and larger holes. It can complete these tasks in a pinch, but it is underpowered for them.

Arguably, the performance in less demanding tasks should carry more weight. We further tested the DCD706’s performance in various common drilling scenarios around the home, such as drilling holes narrower than 1/2 inch into multiple materials. The DCD706 breezed through light and medium-duty jobs we threw at it, as do most comparable drills.

Driving speed

GRK total driving time forward (sec.): 25.3
GRK average driving time forward (sec.): 5.1
GRK total driving time reverse (sec.): 27.0
GRK average driving time reverse (sec.): 5.4

The DCD706 is similarly slow when driving structural screws and lag bolts. The DCD706 doesn’t have the power to rapidly finish heavy-duty driving tasks, although it’ll complete them in a pinch.

We needed to drop a gear to the low setting for added torque to complete our driving speed test, explaining the slow performance.

Driving speed performance isn’t an issue with shorter and more common #6, #8, and #10 screws, which we also tested driving. The DCD706 competently completed the tests driving these screws into various material densities.

Dewalt DCD706 RPM Chart

Max RPM speed 2: 1,475.0
Max RPM speed 1: 432.0

We measured moderately low RPM output with the DCD706 in both speed settings, partly explaining why it didn’t shine in our driving and drilling tests. Higher RPM output would improve the drill’s speed throughout its range.

Advertised max torque (in-lbs): Not advertised
Advertised max torque (ft-lbs): Not advertised

Dewalt no longer advertises the torque of its drills and we currently don’t test torque on a torque meter in-house, like we do for impact drivers.

Instead, review the results of our drilling and driving tests to understand each drill’s torque and RPM performance in practical applications.

Dewalt DCD706 Chuck Closeup

Chuck size: 3/8″
Chuck sleeve material: Plastic

The DCD706’s ratcheting chuck works well and locks down on bits without loosening with usage, as we discovered throughout our testing. However, the chuck sleeve is made of plastic and doesn’t match the premium feel and build quality of other models in our test fleet.

We didn’t perform any drop tests, though we presume any plastic chuck sleeve won’t be as durable as an all-metal sleeve with a direct impact.

Motor & BPM

Dewalt DCD706 Drill Modes

Motor type: Brushless
Action modes: Drill, hammer
Advertised blows per min. (speed 2): 25,500.0
Advertised blows per min. (speed 1): Not advertised
Variable speed trigger: Yes
Kickback control technology: No
Trigger draw length (in.): 0.375

Dewalt made the right call to include a brushless motor at this price point. Dated brushed motors are commonly found in cheaper, less durable, and less efficient drills.

There are two action modes: a standard drill mode that disengages the chuck for peak torque output and a hammer drill mode that does the same but adds 25,500.0 blows per minute (BPM). 25,500.0 BPM is comparably low, yet the hammer drilling mechanism improved drilling speeds sufficiently well in our below drilling tests.

There is no kickback control technology in the DCD706, nor is there a need for one since it’s not powerful enough where wrist injuries are a risk.

Clutch & speed settings

Dewalt DCD706 Clutch & Speed

Speed settings: 2
Clutch settings: 15

The DCD706 includes a standard two-speed transmission to run the hammer drill in a low or high-peed setting in any action mode or the 15 clutch settings. Setting it to drill mode in the low setting generates the maximum torque output.

15 clutch options are right in the middle of the pack. While some drills offer upwards of 20 clutch settings, 15 is more than enough to precisely fine-tune the DCD706’s torque output to avoid stripping screws and finishing with a perfect recess, regardless of the driving task.

Charging time

Dewalt DCD706 Fuel Gauge

Charger tested: Dewalt 20V Max (DCB115)
Charging time 2Ah battery (min.): 39.0
Charging time 4Ah battery (min.): Not tested
Charging time 5Ah battery (min.): Not tested
Charging time per Ah (min.): 19.5
Fuel gauge: On battery

The Dewalt charger that comes with most kits (model DCB115) charges 12V batteries rapidly. In our tests, the charger topped off a 12V Max 2Ah battery in 39 minutes, or 19.5 minutes per Ah.

This charger also charges Dewalt’s 20V battery platform, helping to save space in your shop if you have several tools in the Dewalt ecosystem. But consider that the DCB115 doesn’t charge 20V Max batteries as rapidly.

Design & ergonomics

Stands upright (no battery): No
Stands upright (w/ battery): Yes
Grip material: Rubber overgrip
Magnetic holder: No
Bit holder: No
Belt hook: Yes
Lanyard compatible: Yes

The DCD706 is compact for a drill and has a slight forward-leaning handle for the proper ergonomics when exerting forward pressure when drilling. It doesn’t lean as far forward as other drills and doesn’t have an upward-sloping head, ergonomics that better support an aggressive drilling position.

The DCD706 has a rubber overmold surrounding the grip, which is helpful for shock absorption and gripping power.

An all-metal belt hook included in the box is mountable on either side of the base.


Dewalt DCD706 On Scale

Bare weight (lbs): 2.04
Weight w/ 2Ah battery (lbs): 2.53
Weight w/ 4Ah battery (lbs): Not tested
Weight w/ 5Ah battery (lbs): Not tested

One of the defining features of the DCD706 is its weight. This hammer drill is one of the lightest in our test fleet, weighing in at 2.04 lbs in its bare form. During our testing, we didn’t frequently experience hand or arm fatigue operating the DCD706, which is rare for any hammer drill.

We tested different battery configurations since the working weight can differ meaningfully from the bare tool weight. We recommend combining the DCD706 with Dewalt’s 12V Max 2Ah battery for good drilling performance and weight balance in a lightweight setup.

Pair the DCD706 with Dewalt’s 12V Max 5Ah battery for a longer run time if weight is less of a concern. However, upgrading to Dewalt’s 20V Max drill lineup may be more suitable as you increase the battery Ah capacity since the weight and footprint increase moving up to a 12V 5Ah battery.

Dewalt DCD706 Footprint1

Max height (in.): 8.500
Max width (in.): 2.500
Chuck to back length (in.): 6.625
Base length (in.): 3.500
Base width (in.): 2.500

The DCD706 is reasonably compact when measured in many of its dimensions. Notably, it casts a thin shadow from the front and behind, it isn’t tall with a battery, and the tip-to-tail length is short.

Combined with its weight, the DCD706 feels nimble in hand without the bulky heft that plagues most hammer drills, even some competing 12V models.

Drilling clearance

Min. interior width clearance (in.): 8.250
Min. top edge clearance (in.): 1.375
Min. interior 45-deg. clearance (in.): 6.750

Since it is a compact hammer drill, the DCD706 drills wells in situations where there are obstructions or tight corners to reach into. Notably, it performed best in our interior width and top-edge clearance tests. In practice, the DCD706 fits easily between two vertical boards and easily reaches under shelves and when obstructed from above.

Compare drilling clearance test results

Auxiliary arm

Auxiliary arm: No

The DCD706 doesn’t include an auxiliary handle to control recoil and enhance stability during heavy-duty drilling tasks. But we don’t see this as a downside. The DCD706 isn’t designed to tackle the heaviest-duty drilling tasks, such as drilling wide and deep holes in masonry or wood, where an auxiliary handle is helpful.


Dewalt DCD706 Noise Chart

Max no-load noise (dBA): 79.8
Max drilling noise (dBA): 93.7

The DCD706 is moderately loud when drilling under load. We measured the maximum noise output when hammering and drilling stacked lumber. The dBA results rival the same noise the top impact drivers generate, which can be harmful with prolonged exposure.

Dewalt DCD706 Light Wall
Dewalt DCD706 Light Closeup

Light: Yes
Light location: In base
Light positions: 1
Customizable light settings: None
Light count: Single LED
Light active time (sec.): 20.0

There is a single bulb located in the base that shines upward. It sufficiently illuminates the work surface in front of the DCD706’s nose. However, we prefer drill designs that include the light near the trigger and shine straight forward, improving the light’s versatility and ensuring the intended area is most brightly lit.

There are no advanced light features, such as a dedicated spotlight mode and the ability to turn off the light, which some of the best Dewalt drills include.


Tool warranty (years): 3
Battery warranty (years): 3

Dewalt stands behind the durability of its drills with exceptionally long warranties. The DCD706 has a three-year warranty. Dewalt’s 12V Max batteries include a three-year warranty.

Dewalt also offers free maintenance and replacement of worn parts for one year for the DCD706.
