The 2551-20 follows the design language familiar to Milwaukee’s M12 impact driver lineup with a forward-biased handle and head angle that reaches toward the sky. This design provides solid reach in certain driving scenarios. The handle includes a rubber overgrip that offers good shock absorption.

There is an included belt hook mountable on either side, but no bit holder or magnetic fastener holder is onboard, unlike some Ryobi impact drivers with these features built into the tool.

Uniquely, the battery slots into the handle to give it a svelte design compared to other impact drivers, where the battery widens and lengthens the base. Milwaukee’s higher Ah M12 batteries are more traditionally designed to widen and lengthen the base, albeit remaining extremely compact. Without a battery, the 2551-20 doesn’t stand upright.

Weight

Milwaukee 2551-20 On Scale

Bare weight (lbs): 2.02
Weight w/ 2Ah battery (lbs): 2.41
Weight w/ 2.5Ah battery (lbs):  Not tested
Weight w/ 4Ah battery (lbs):  Not tested
Weight w/ 5Ah battery (lbs): Not tested

The 2551-20 is moderately heavy for a 12V impact driver in its bare form and with a battery but is lightweight compared to most 18V impact drivers, helping to reduce muscle fatigue.

The working weight can differ significantly depending on the battery run in your setup. To keep it lightweight, we recommend combining the 2551-20 with Milwaukee’s M12 Red Lithium CP 2Ah battery for a good balance of performance and weight.

If weight is less of a concern, Milwaukee offers several higher Ah M12 batteries in its lineup. However, you forego the in-handle design for a slightly bulkier footprint and weight. Upgrading to Milwaukee’s M18 lineup may be more suitable as the size increases.

Motor

Motor: Brushless
Impacts per minute: 3,400.0

Brushless motors, like the one included in the 2551-20, improve driving efficiency, increase battery run time, and are more durable than their brushed motor counterparts.

Understandably since it’s a hydraulic impact driver, the 2551-20’s advertised 3400.0 impacts per minute are low, explaining some of the slow driving performance in our tests and some of the precision screw finishing as well. Most tools have tradeoffs, and the impacting frequency is worth considering based on your intended usage.

One differentiating factor is that the percussive impact is powered by hydraulic action. The expanding and contracting oil pulses spin the collet, resulting in a less violent and more prolonged impact than traditional hammer-impacting models.

Motor

Motor: Brushless
Impacts per minute: 4,000.0

Brushless motors, such as Milwaukee’s Powerstate motor included in the 3453-20, are highly efficient, increase battery run time, and are more durable than their brushed motor counterparts.

The advertised 4000.0 impacts per minute are high for a sub-compact, partly explaining the snappy driving performance in our tests.

Drive modes

Milwaukee 2551-20 Drive Modes

Drive modes: 4
Drive mode 1:  High speed 
Drive mode 2:  Medium speed 
Drive mode 3:  Low speed 
Drive mode 4:  Self-tapping 
Variable speed trigger: Yes

There are four driving modes on the 2551-20, great for driving versatility. Drive modes we label as 1, 2, 3, and 4 correspond to high speed, medium speed, low speed, and self-tapping screw modes. The advertised impacts per minute for the speed modes are 3400.00, 2200.0, and 950.0, respectively.

Drive mode 1 is ideal for heavier-duty tasks, such as driving lag bolts and decking screws. This mode finishes screws nicely, compared to the brute force high-speed modes on most 18V impact drivers.

Drive mode 2 is the best if you want a clean and consistent screw recess. The mode has enough power to drive screws into dimensional lumber, treated lumber, plywood, and hard and softwood.

We found ourselves favoring drive mode 2 over drive mode 1 since the lower setting lacks power, and drive mode 2 is already highly accurate in all density materials.

The self-tapping mode works well enough driving standard screw sizes in ½-inch to 1-inch lengths in thin sheet metal. In this mode, the collet spins and then stops once a specific light rotational force is reached, then it starts again slowly for a short moment. Holding the trigger repeats the cycle, helpful when the first cycle doesn’t set the screw at full depth. Since the rotational force is so sensitive, this drive mode only works well for niche driving scenarios.

Also, the trigger must be fully pushed. Any shorter trigger draw results in operating in a normal impacting mode.

Drive modes

Milwaukee 3453-20 Drive Modes

Drive modes: 4
Drive mode 1:  High speed 
Drive mode 2:  Medium speed 
Drive mode 3:  Low speed 
Drive mode 4:  Self-tapping 
Variable speed trigger: Yes

Four driving modes on the 3453-20 vastly improve driving versatility over single-mode models. Drive modes we label as 1, 2, 3, and 4 correspond to high speed, medium speed, low speed, and self-tapping screw modes. The advertised impacts per minute for the speed modes are 4000.0, 3500.0, and 1300.0, respectively.

Drive mode 1 is the best option for heavy-duty tasks, such as driving lag bolts and decking screws. This mode finishes screws nicely enough compared to the brute force high-speed modes on most 18V impact drivers. But any impact driver’s high-speed setting is rarely the best option for an accurate screw finish.

Drive mode 2 is the best for a clean and consistent screw recess in most materials. The mode has enough power to drive screws into dimensional lumber, treated lumber, plywood, and hard and softwood.

We found ourselves favoring drive mode 2 over drive mode 1 since the lower setting lacks power, and drive mode 2 is already highly accurate in all density materials.

The self-tapping mode works well enough driving common screw sizes in 1/2-inch to 1-inch lengths in thin sheet metal. In this mode, the collet spins until impacting and slows down to tap the screw.

This approach differs from other Milwaukee impact drivers, with a more consistent and versatile self-tapping drive mode. The Milwaukee M12 Fuel Surge 2551-20 has a better self-tapping mode. The 2551-20’s collet stops once a specific light rotational force is reached, and then it starts again slowly for a short moment. The 3453-20 doesn’t restart when holding the trigger, and we found this lacking feature reducing the self-tapping mode’s consistency.

Driving speed

GRK total driving time forward (sec.): 24.8
GRK average driving time forward (sec.): 5.0
GRK total driving time reverse (sec.): 17.7
GRK average driving time reverse (sec.): 3.5

The 2551-20 isn’t designed for driving big structural screws and lag bolts, as demonstrated by its lagging performance in our GRK speed tests designed to test brute force. However, when put up against 12V impact drivers, the 2551-20 shines in these tests.

It’s also an extremely capable impact driver for its intended usage, primarily driving screws 3 inches and shorter. Speed isn’t necessarily crucial in these scenarios. Instead, capable driving power and accuracy prevail. The 2551-20 excels in these lighter and medium-duty jobs, especially with its quiet oil-impulse impact.

GRK total driving time forward (sec.): 21.7
GRK average driving time forward (sec.): 4.3

The 3453-20 efficiently and impressively drove long GRK screws into treated lumber, far outshining other sub-compact impact drivers in our driving speed tests. But consider that the driving speed for big screws and lag bolts doesn’t compete with more powerful 18V impact drivers. So, it’s not an ideal fit for heavy-duty driving jobs only.

For the most common driving tasks around the home, the 3453-20 is fantastic. It powerfully drives decking screws and quickly drives common screw sizes into dimensional lumber, plywood, softwoods, and hardwoods.

All hydraulic impact drivers offer lower torque output than equivalent models with anvil-based impacting mechanisms, including the 2551-20. This impact driver generates enough torque to bust loose some lug nuts and light bolts, but it isn’t powerful enough to tackle more stubborn fasteners. The torque profile is one of the trade-offs made for the quieter and smoother impacting experience.

A frequent theme in Milwaukee’s flagship Fuel lineup is a trade-off between torque and speed depending on the task. Milwaukee gears most of its Fuel lineup to speed through the most demanding tasks, giving up some speed performance to competitors in lighter-duty jobs. This approach explains why the 3453-20 is geared to generate such high torque output.

The 3453-20 packs in a powerful torque punch in the 12V class. It not only secured the podium position for torque output in our Summer ’23 sub-compact test fleet but it also outpaced many larger 18V impact drivers.

Battery run time

Power type: Cordless
Battery run time (min.): 26.0
Battery tested: 12V Red Lithium CP 2Ah (48-11-2420)
Voltage: 12

One crucial downside is the lacking battery run time performance, which is familiar with several Milwaukee impact drivers.The Makita 12V CXT DT04Z and Dewalt 12V Xtreme DCF801 have much better battery life.

We tested battery run time with the 2Ah battery version. With an M12 5Ah battery, expect the battery run time to increase but continue underperforming competing models running the same Ah setup.

The primary downside of the 3453-20 is its poor battery run time performance, which is one of the worst results we’ve encountered.

We tested battery run time with the 2Ah battery version. With a higher Ah M12 battery, expect the battery run time to continue underperforming competing models running the same Ah setup.

The practical run time may differ under load since Milwaukee offers highly efficient and powerful motors. But we haven’t tested beyond no-load run time to understand how it performs.

Battery lineup

Milwaukee M12 Battery Lineup

Milwaukee offers 1.5Ah, 2Ah, 2.5Ah, 3Ah, 4Ah, 5Ah, and 6Ah batteries in its M12 lineup. Upgrading to the higher Ah options increases battery run time and improves driving performance, though we’ve not tested all of these batteries to understand the cost tradeoffs. The 4Ah and higher batteries increase the base footprint over the in-handle-only, smaller Ah versions.

Having at least two batteries in your setup is best so you don’t miss a beat when draining one battery. We recommend buying two Milwaukee M12 Red Lithium CP 2Ah batteries for most M12 impact driver setups for a good balance of performance, price, and size.

Many Milwaukee impact drivers come in kits with chargers that charge multiple voltage batteries in one, conveniently saving space in your shop if you have several M12 and M18 ecosystem tools.

Max RPM drive mode 3 (rev.): 927.0
Max RPM drive mode 4 (rev.): 2,773.0

The 2551-20 is moderately fast for a 12V impact driver, helping to set screws quickly. One potential risk of a high RPM is cam-out and stripping screws. This risk is more of an issue for more powerful 18V impact drivers. The 2551-20 is well-balanced and impresses with its ability to avoid cam-out and stripped screws.

There is no significant measured RPM difference between forward and reverse for each drive mode. Some models increase RPM in reverse for specific drive modes to help bust loose bolts and stubborn screws. We didn’t encounter a situation where the 2551-20 was underpowered removing screws.

The 3453-20 is one of the fastest impact drivers we’ve come across. The High RPM performance partly explains why it breezes through driving common screw sizes and lengths. The high RPM also helps set screws quickly, though there is some cam-out risk with such a high RPM. However, the cam-out risk is reduced significantly by using the other drive modes and by the fact that it’s a 12V impact driver with less torque than an 18V impact driver.

There is no significant measured RPM difference between forward and reverse for each drive mode. Some models increase RPM in reverse for specific drive modes to help bust loose bolts and stubborn screws. We didn’t encounter a situation where the 3453-20 was underpowered removing screws.

Noise

2551-20 Impact Driver Noise Chart

Max noise no load (dBA): 87.7
Max impacting noise (dBA): 86.1

The 2551-20 is a dream regarding its noise performance, which is one of the primary reasons to buy a hydraulic impact driver. The noise when impacting is exceptionally low compared to hammer-based impact driver designs.

The noise performance is most noticeably low when driving standard screw sizes and lengths under 3 inches. The 2551-20 is as close to whispering as you’ll get with an impact driver. We measured as low as 84.3 dBA impacting short screws, approximating an airplane’s inside ambient noise.

Consider the Milwaukee M18 Fuel Surge 2760-20 for a more powerful hydraulic impact driver with exceptional noise performance.
