About This Product

The Milwaukee M12 FUEL SURGE 1/4 in. Hex Hydraulic Driver is the industry's first 12-Volt hydraulic impact driver. Featuring the FLUID-DRIVE Hydraulic Powertrain, the hydraulic impact will allow users to experience operation up to 2X quieter with less vibration for smoother and faster driving speeds compared to standard impacts. The compact size of the tool and battery provides users with unmatched access in tight spaces & allows for easy transport on a tool belt and easy fitting into a job site tool bag. Performance is not sacrificed despite lower peak torque due to its Longer Sustained Torque that allows the tool to complete core users most common applications. The POWERSTATE Brushless Motor delivers up to 0 RPM-3,000 RPM with constant power output to drive screws faster. Built-in REDLINK PLUS intelligence is the most advanced electronic system on the market, preventing damage to the user's tool and battery caused by overloading or overheating. The cordless impact driver is compatible with all Milwaukee M12 REDLITHIUM Compact Batteries or Extended Capacity Batteries, delivering users with more work per charge and more work over the life of the pack than competitive batteries. The impact driver's 4-Mode DRIVE CONTROL provides users with greater control over output speed and power for greater versatility in a wide range of applications. Self-Tapping Screw Mode reduces walking when users are self-tapping screws as well as reduces overdriving, breaking and stripping out screws.

Highlights

  • FLUID-DRIVE hydraulic powertrain reduces metal on metal contact within the tool, delivering quieter operation, smoother performance and increased durability over a standard impact
  • Longer sustained torque delivers similar drive times in application as most 12-Volt impact drivers
  • Up to 2X quieter operation makes this tool ideal for occupied spaces
  • Compact head length and compact battery footprint gives more access than competitive impact drivers
  • POWERSTATE brushless motor delivers maximum power and long motor life
  • REDLINK PLUS intelligence prevents damage to the tool and battery due to overloading or overheating
  • REDLITHIUM batteries deliver more work per charge and more work over the life of the battery
  • Includes: 2551-20 (tool-only), belt clip

Questions & Answers

Does the surge have more torque than just the m12 fuel
ByJun 21, 2026
1 Answer | 
Answer This Question

The M12 FUEL Impact Driver (2553) max torque is 1,300 in-lbs and the M12 FUEL SURGE Hydraulic Driver (2551) max torque is 450 in-lbs. If you need maximum torque, the regular M12 FUEL Impact Driver beats the SURGE by nearly 3X. If you need quieter, controlled fastening, SURGE wins.

    Could this be used to polish small areas on my car’s paint?
    ByJun 7, 2026
    1 Answer | 
    Answer This Question

    No—using the M12 FUEL™ SURGE™ 1/4" Hex Impact Driver to polish car paint is not recommended. Using adapters on an impact driver for polishing is unsafe for paint finishes and not supported by Milwaukee.

      How do you limit the amount of Torque when you are installing fasteners that can strip or break? Or driving screws into softer materials? Will a lighter trigger setting reduce the speed and torque?
      ByDec 24, 2025
      1 Answer | 
      Answer This Question

      To limit the torque on the Milwaukee M12 FUEL SURGE 12V Lithium-Ion Brushless Cordless 1/4 in. Hex Impact Driver, you can use its 4-Mode DRIVE CONTROL feature. This allows you to adjust the output speed and power to suit your application, such as installing fasteners in softer materials or preventing stripping or breaking screws. Additionally, the Self-Tapping Screw Mode is specifically designed to reduce overdriving, breaking, and stripping screws, making it ideal for delicate tasks.

                    Useful to have this M12 FUEL SURGE impact driver in my collection of tools. There are situations where an impact driver is the best option for getting a job done. Others provide plenty of comments about the tool's strengths, so one thing different I will comment on is how I use the handy case that came with the kit: I keep battery chargers on a workbench and don't need to keep a charger in the case, so instead I use that space to keep driver bits. The case that comes with Milwaukee's 45-piece impact driver bit set fits right in there, and it is super convenient to have all the impact bits in the same bag as the driver (plus a battery). I know when I grab that "impact driver bag" everything I need is right there with it. Regarding the M12 Blower that came with bundle, that's a nice size blower that's getting plenty of air time (lol) in the shop and in the yard. Overall a solid bundle at a great price.

                      Nice and quiet with lots of torque
                      I love the torque to weight ratio. It’s obviously not as powerful as the M18 but for a lot of what I do, it is more than powerful enough and so compact and light. Perfect for hinges etc. and it’s not too loud.

                      Great addition to the household tool kit
                      The 3/8 ratchet isn't anything special, but it is helpful. The FUEL SURGE driver is amazing. It drives screws quickly, with hardly any noise or recoil/vibration. With how compact and quiet it is, it is now the junk drawer staple and gets used for every quick project in the house. The quiet hydraulic drive is a great feature for working on a project without creating a bunch of noise and disrupting the rest of the household. I wish I had bought it sooner. The multi-drive power function is great for changing between high torque for driving large screws and low torque for assembling more delicate fasteners.

                        This drill/driver is a wonderful tool. I love this M12 lighter, smaller version. It has tremendous torque with the impact. The settings allow for using a lighter touch when required. The 2 batteries are a bonus. The 2AH batteries last a long time I highly recommend this package.
                        by
                        Extremely disappointed, especially since Milwaukee and its fans always claim you pay higher prices for higher quality. Owned the driver for a month, used twice on simple projects loosening and tightening screws, and the collet is now loose and full of slop in holding bits in. My Ryobi driver has no play whatsoever by comparison.

                        Absolutely loving this M12 Surge. I already have the M18 Impact and the M18 Surge, but wanted an additional Surge (since I rarely use the regular impacts after owning the Surge). It seems to have all the power I need for most applications I'll come across. Ratchet has been a great addition also. Haven't used it much, however, very handy the little I have used it.
