The Milwaukee M12 Fuel Surge 1/4" Hex Hydraulic Driver Bare Tool (2551-20) is the industry's first 12-volt hydraulic driver. Featuring FLUID-DRIVE Hydraulic Powertrain, the hydraulic driver will let you 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 give you unmatched access in tight spaces and allows for easy transport on a tool belt and easy fitting into your job site tool bag. The POWERSTATE Brushless Motor delivers up to 0-3,200 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 your tool and battery caused by overloading or overheating. The cordless hydraulic driver is compatible with all Milwaukee M12 REDLITHIUM Compact Batteries or Extended Capacity Batteries, providing you 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 gives you greater control over output speed and power for greater versatility in a wide range of applications. Self-Tapping Screw Mode reduces walking when you are self-tapping screws as well as reduces overdriving, breaking and stripping out screws.

  • 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 12V impact drivers
  • Up to 2X quieter operation makes this tool ideal for occiped spaces

Rated 5 out of 5 by from Powerful and quiet I have owned and used several other impact drivers. Ridgid 18v, Makita 18v, and the M12 fuel normal impact drivers. This thing is make so much less noise it’s amazing. I work as a service technician and often work in occupied spaces, it is nice to have a tool that won’t blow the room up with sound when I really need an impact driver. It is also much more comfortable when in tight spaces because of the size and the sound. When inside an air handler and you have to have the driver next to your face the noise reduction is a lifesaver. The power is amazing as well, I haven’t noticed any real difference in power compared to the 18v’s I have used.

Rated 5 out of 5 by from Silent but violent The Milwaukee M12 Surge 1/4” Hex Imapct is surprisingly quiet for the amount of power it produces. I’m a 25 year experienced Locksmith with years of experience in the commercial door/frame/hardware industry. The M12 Surge gives you the ability to control your work piece correctly without stripping or damaging screws or the surface materials. I also use an M18 hex impact non-surge when I have heavy fastening to do for which control isn’t always a concern but power is preferred. I am currently using the Milwaukee M12 XC4.0 batteries with excellent runt time. I would highly recommend the Milwaukee M12 Surge 1/4” Hex Impact to any one.

Rated 5 out of 5 by from Most used power tool in my collection What an amazing impact driver! Absolutely love this surge impact. I have the Gen III M18 fuel impact driver as well. Both amazing but the first one I reach for is the M12 surge. The M12 Surge has amazing power for its size. It’s actually a lot quieter as advertised too. The first setting slows down when it starts to sense some torque. It keeps things under precision control and helps avoid over driving screws or fasteners till they strip out. I was impressed when using on the slotted screws in the 1937 house I recently bought. Slows down enough to keep on the slot with out jumping off.

Rated 5 out of 5 by from I would buy again! Actually Bought 2 more! I’ve been using impact style drivers for years installing blinds/shades and interior shutters. During an install a customer asked me to try his surge driver in place of my fuel driver. First screw I was sold! More control,less noise and vibration and the adjustment on speed control is awesome for delicate small screws. Installing stainless steel trim screws with the small S1 head is a breeze without destroying the heads(anyone using those knows how easy they strip). I can’t say enough good about this driver except I bought 2 more for my Dad and friend who has a local cabinet shop. The noise difference alone is worth the price. Thanks Milwaukee for this amazing tool!

Rated 5 out of 5 by from Fantastic tool I have been in the HVAC/R industry for 14+ years, worked as a Install helper, Preventive Maintenance, Service, Lead installer for all types of residential equipment. The m12 Surge has been a game changer for me, i use an impact almost every day at work. Prior to the Surge i used 2 gens of M18 impacts and 3 gens of m12 impact. The Surge will not win any speed challenges my the constant torque is impressive! The thing i love about it most is the Noise, it is an incredible difference between the m12 Surge and the m12 Fuel impact, when my helper uses his m12 impact it rattles your ears when you are use to the Surge. One of the best impacts on the market! and i will be buying it again in the future

Rated 5 out of 5 by from So quiet compared to other impacts I purchased the surge to use in office spaces during business hours. Using our other impacts to hang tvs or whatever are so loud and disruptive to use while people are working. I was really surprised when I first used the surge, still a little noisy but nowhere near other impacts. It’s a great compact tool, and an excellent option when working in spaces where noise can be an issue. I’ve been on several sites where you are not allowed to use hammer drills, impacts or powder actuated tools during business hours. This tool would get the job done and fit within the noise requirements. Great job Milwaukee!

Rated 5 out of 5 by from Lots of power, great battery life. Super impressed with the m12 surge, mounted 7 double roof drains and backing for each and im still 4 out of 4 bars on a 4.0 battery, next day i was hanging backing for some tankless water heaters, showers, steam generator, and some wall hung sinks, first screw needed to go through a knot, broke a brand new dewalt star head bit my coworker gave me, switched to the carbide Philips tip and switched to 3" philips screws, hung the rest of the boards no problem, including that first screw into the knot.

Rated 3 out of 5 by from Quieter less powerful 1/4” impact driver I have been using the “Surge” for a little over a month now and am not sure if I prefer it over the M12 fuel driver. It seems to have less power although it is very hard to determine so would have to guess it is at least the same. It does drains batteries quicker, which is disappointing, I do like how much quieter the “Surge” operates. If noise is not an issue I’d be hard pressed to recommend the Surge over the the Fuel driver. If you need a quieter tool this is the one for you
