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: No

The 2607-20 leans slightly forward but doesn’t have an upward-sloping head that positions the drill in an aggressive stance when drilling. The combined angles help keep the drill flat when rotating your wrist slightly forward, as is common when setting up to bore a hole.

Otherwise, the grip is covered in a rubber overmold that improves shock absorption and gripping power. There is also no onboard bit holder or magnetic plate to hold fasteners, although both can be purchased from third parties and attached to the 2607-20.

A belt hook included in the box is mountable on both sides at the back of the base.

The 2904-20 has a forward-leaning handle and a slight upward-pointing head that properly position the drill in the correct plane when exerting forward pressure when drilling.

While an all-metal belt hook in the box is mountable on either side of the base, no onboard bit holder or magnetic plate to store screws is included. Both can be purchased in the after-market from third parties.

Weight

Milwaukee 2607-20 On Scale

Bare weight (lbs): 3.03
Weight w/ 2Ah battery (lbs): 3.97
Weight w/ 4Ah battery (lbs): Not tested
Weight w/ 5Ah battery (lbs): 4.64

The 2607-20 is moderately heavy for an 18V drill, weighing in at 3.03 lbs in its bare form. Over longer and repetitive drilling sessions, expect minor muscle fatigue in your hand, wrist, and forearm.

We tested different battery configurations since the working weight can differ meaningfully from the bare tool weight. We recommend combining the 2607-20 with Milwaukee’s M18 Red Lithium CP 2Ah battery for as lightweight of a setup as possible without limiting performance meaningfully.

Pair the 2607-20 with Milwaukee’s M18 Red Lithium XC 5Ah battery for a longer run time and improved drilling performance if weight is less of a concern.

We look forward to when power tool technology advances to the point where the most powerful drills are compact and light. Unfortunately, that day has yet to come, including with the 2904-20, which is heavy and bulky feeling in hand. This drill is one of the heavier hammer drills in our test fleet and one of the heavier options on the market.

We tested different battery configurations since the working weight can differ meaningfully from the bare tool weight. We recommend combining the 2904-20 with Milwaukee’s M18 Red Lithium CP 2Ah battery for the lightest setup we’d suggest that is still powerful with an acceptable battery life.

Base width (in.): 3.125

The 2607-20 is moderately svelte when looking at its height with a battery and head width, helping it fit into some tight areas. However, the 2607-20 is incredibly long from tip to tail, with a significant portion of the chuck and head in front of the trigger.

The almost comically elongated nose section biases the weight at the front of the tool, causing it to not stand upright without a battery and leading to some hand fatigue when holding the drill flat.

Motor & BPM

Milwaukee 2607-20 Drill Modes

Motor type: Brushless
Action modes: Drill, hammer
Advertised blows per min. (speed 2): 28,800.0
Advertised blows per min. (speed 1): 7,200.0
Variable speed trigger: Yes
Kickback control technology: No
Trigger draw length (in.): 0.375

Impressively at this budget price point, the 2607-20 includes a brushless motor, improving the motor longevity and driving efficiency over brushed motors. Even as brushless motors have become commonplace, many drills in this price range still opt for a brushed motor to cut costs.

The brushless motor has three action modes. The driving mode engages the clutch to fine-tune the driving profile based on the torque needed.

The drill mode disengages the clutch for unfettered torque performance.

The hammer mode acts like the drill mode but layers in a hammering mechanism that generates 28,800.0 blows per minute in the high setting.

While the hammering functionality improves drilling speed, the comparatively low hammering rate doesn’t drastically improve speeds, as evidenced by our drilling speed tests below.

Advertised blows per min. (speed 1): Not advertised
Variable speed trigger: Yes
Kickback control technology: Yes
Trigger draw length (in.): 0.375

The 2904-20 includes Milwaukee’s Powerstate-branded brushless motor, which offers better efficiency and longevity than brushed motors.

Two drill options are located on the same set ring as the clutch settings. The standard drill mode disengages the clutch, and the hammer drill mode does the same but layers in 33,000.0 blows per minute (BPM) to improve drilling speeds.

The hammering rate is high, explaining why the hammer drill mode effectively increased drilling speeds in our tests.

One standout feature is that the 2904-20 features kickback control technology to reduce the risk of wrist injuries. Near the light in the base, there is a small Autostop light that flashes when the kickback mechanism is triggered when binding up.

We tested the kickback control using several large spade and forstner bits and found that it worked as advertised. But we don’t run standardized tests to understand if Milwaukee’s technology works better than any competing kickback control technology.

Clutch & speed settings

Milwaukee 2607-20 Clutch & Speed

Speed settings: 2
Clutch settings: 18

The 2607-20 includes a familiar two-speed gearbox to run the drill at a high or low RPM in any action mode. There are also 18 clutch options, which is modestly high. Whether the number of clutch settings is a pro or con depends on how you use the drill.

Access to more clutch settings allows you to drive screws with more precision, albeit most people don’t use the full clutch settings available.

Compare drill clutch and speed settings

Clutch & speed settings

Milwaukee 2904-20 Clutch & Speed

Speed settings: 2
Clutch settings: 16

The two-speed gearbox determines the RPM output and can be used in drill and hammer drill mode when the clutch is disengaged or when a clutch setting is selected.

While 16 clutch settings isn’t the highest number available, it’s more than most people will need in practice. Including more clutch settings would only allow you to finely tune the torque to a given driving task. Still, the 2904-20 is precise when the proper clutch setting is engaged.

Chuck

Milwaukee 2607-20 Chuck Closeup

Chuck size: 1/2″
Chuck sleeve material: Metal

Impressive for this price point, the 2607-20 includes an all-metal chuck sleeve. Many competing models choose plastic instead. Opting for metal makes the drill feel more premium and improves durability.

Throughout testing, we were also impressed with how well the three-jaw chuck locked onto bits and retained them when frequently switching between forward and reverse during regular testing. Some other hammer drills inadvertently loosen the chuck when releasing the trigger and switching between forward and reverse without holding the chuck.

Chuck

Milwaukee 2904-20 Chuck Closeup

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

The 2904-20 has an exceptional all-metal chuck that is more premium than most drills, especially the knurled metal sleeve that tightens the chuck with the right amount of friction on your hand for grip.

The three-jaw chuck also holds bits well since the ratcheting mechanism locks tightly onto a bit when tightening. We didn’t run into any scenarios where the chuck inadvertently loosened during use.

Auxiliary arm

Auxiliary arm: No

The 2607-20 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 2607-20 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.

We’d see not including an auxiliary arm as a downside if it had more muscle.

Auxiliary arm

Milwaukee 2904-20 Auxiliary Arm

Auxiliary arm: Yes

The 2904-20 includes an auxiliary handle to control recoil and enhance stability during heavy-duty drilling tasks, improving user safety. The 2904-20 is a powerful drill, so it makes sense that an auxiliary arm is included.

The handle is easy to attach and remove just behind the chuck and is mountable on either the right or left side.

Drilling speed

Drilling speed total time (drill mode, sec.): 16.0
Drilling speed average time (drill mode, sec.): 3.2
Drilling speed total time (hammer mode, sec.): 15.3
Drilling speed average time (hammer mode, sec.): 3.1
Hammer mode speed improvement: 4.4%

The 2607-20 has fantastic drilling performance when put up against similarly-priced budget models in and outside of the Milwaukee 18V lineup.

We designed our drilling speed tests to understand how each drill performs at the top of its range. The 2607-20 is one of the fastest and smoothest hammer drills in our low to mid-range price test fleet.

It’s not fast enough to blast chips out when boring holes like a flagship drill. But it did smoothly and quickly complete our drilling speed test without binding up and easily cleared chips from the hole.

Not as impressive, the hammer drill functionality doesn’t improve speed much. We expect a highly capable hammer functionality to improve speeds by 20.0% or more over the standard drill mode.

The 2607-20’s hammer functionality only improved drilling speeds by 4.4%. A higher hammering rate and more power would improve the speed when drilling into masonry and thicker lumber. We’d consider the unimpressive hammering performance more of a downside if the 2607-20 didn’t quickly bore big holes, which isn’t the case.

Drilling speed

Drilling speed total time (drill mode, sec.): 10.8
Drilling speed average time (drill mode, sec.): 2.2
Drilling speed total time (hammer mode, sec.): 8.0
Drilling speed average time (hammer mode, sec.): 1.6
Hammer mode speed improvement: 25.9%

The 2904-20 rapidly bores small and wide holes alike. Importantly for a performance-focused high-end hammer drill, it sustained high RPMs throughout the depth of the holes bored in our drilling speed tests. The 2904-20 was never close to binding up, and it easily cleared chips from the hole.

We also tested the 2904-20 in various drilling applications, including drilling a range of width holes using spade and forstner drill bits. We didn’t encounter a task where the 2904-20 didn’t either match or outperform other flagship hammer drills.

Consider that the 2904-20 may be overkill for most homeowners. Few tasks around the home are likely to push it to the limits, and there are some cheaper and still powerful drills if you aren’t a prosumer and prefer to save some money.

Driving speed

GRK total driving time forward (sec.): 13.1
GRK average driving time forward (sec.): 2.6
GRK total driving time reverse (sec.): 9.6
GRK average driving time reverse (sec.): 1.9

The 2607-20 won’t win any driving speed contests when driving big lag bolts and other structural screws. You need to open up more of your wallet to secure that crown. But the 2607-20 is more than capable of driving long lag bolts in the high setting, as seen in our video above.

Context is important when reviewing our driving speed test. There isn’t a massive time difference between the fastest drills and those finishing in the middle of the pack. For example, middle-of-the-test pack models like the 2607-20 averaged roughly 2.5 seconds per GRK RSS screw. The fastest, highest-end drills were around 1.5 seconds on average.

There’s no denying how satisfying it is to quickly finish a screw with brute force driving power. However, the time savings of roughly one second per screw isn’t a game changer for most people considering this hammer drill.

The 2904-20 also performed exceptionally well in our driving speed tests, breezing through driving and removing five GRK RSS screws from 2×6 stacked lumber.

We also tested driving various common length and size shorter screws and different gauge lag bolts and decking screws to understand how the 2904-20 performs across a range of tasks. In each test, it finished fasteners rapidly with power.

Torque

Advertised max torque (in-lbs): 500.0
Advertised max torque (ft-lbs): 41.7

While 500.0 in-lbs of advertised torque won’t secure a podium position for the highest torque output, it beats most drills we’ve tested around the same price point. This data point further evidences why it’s one of the best budget drills around, with unmatched build quality and performance in its category.

Note: We don’t currently test drill torque in-house, as we do for impact drivers using a torque meter. The torque commentary discussed here relies upon both advertised torque specifications provided by manufacturers and practical insights learned from performance in our various drilling and driving tests.

Torque

Advertised max torque (in-lbs): 1400.0
Advertised max torque (ft-lbs): 116.7

The 2903-20 advertises the highest torque of any drill in our Summer ‘23 test fleet with 1,400.0 in-lbs. This level closely matches the performance of some of the best impact drivers, which are safer and more user-friendly options when driving lags and big fasteners.

Throughout testing, there were several instances where the combined RPM and torque profile led to binding in heavy-duty applications. In those scenarios, Milwaukee’s Autostop kickback control technology shined, helping to avoid wrist injury by instantly stopping the motor.

Battery lineup

Milwaukee M18 Battery Lineup

Milwaukee offers 1.5Ah, 2Ah, 3Ah, 4Ah, 5Ah, 6Ah, 8Ah, and 12Ah batteries on the M18 platform. 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 buying a Milwaukee M18 Red Lithium CP 2Ah and a Milwaukee M18 Red Lithium XC 5Ah battery for most M18 drill setups for a good performance, price, and size balance.

RPM

Milwaukee 2607-20 RPM Chart

Max RPM speed 2: 1,686.0
Max RPM speed 1: 429.0

One downside is that the 2607-20 isn’t a high RPM hammer drill. Its RPM output in the high setting is average, whereas the RPM in the low setting falls near the bottom of the pack.

As a result, in practice, the 2607-20 doesn’t set screws quickly, leading to occasionally fumbling the screw before the tip grabs the work material. This drill will also drive and drill more slowly than most in the low setting, albeit the torque increases.

RPM

Milwaukee 2904-20 RPM Chart

Max RPM speed 2: 2,055.0
Max RPM speed 1: 467.0

The 2904-20 shined in our drilling and driving speed tests due to the high RPM output sustained under load. We tested the RPM output with a contact tachometer, and the 2904-20 is among the fastest in our test fleet.

The 2904-20 also has a moderately high RPM in the low setting, meaning it’ll drill faster than other lesser drills when gearing down for extra torque.

Min. top edge clearance (in.): 1.375
Min. interior 45-deg. clearance (in.): 7.750

If you frequently drill flatly between two vertical boards, then the 2607-20 isn’t the drill of choice. The extremely long tip-to-tail length limits the spaces it can fit into without operating the drill at awkward angles.

The 2904-20 isn’t the ideal drill for fitting through narrow spaces and into tight corners. While it is admirably compact compared to other hammer drills in its class, it is still bulk overall.

In the three clearance tests we conducted, it performed best with its interior width clearance. It fits moderately well between two vertical boards, primarily thanks to its tip-to-tail footprint.
