Both satisfying and efficient
Review Image by LJ
This is my first Milwaukee tool, and one of the first power tools i’ve bought new. Coming from eBay 12v lithium Makita brushed drills/drivers, of course the jump from brushed to brushless is impressive. Despite loving the fine, instant and precise trigger actuation of my Makita tools, this definitely competes and maybe isn’t exactly as slick, but in use I’ve never noticed a difference. In terms of everyday usability, it’s surprisingly heavier which is the sole reason I went 12v for both lineups but in use I absolutely don’t mind the extra weight. It’s never felt cumbersome or uncomfortable. Now for the elephant in the room, the hydraulic impact mechanism. Not only is it substantially quieter which I love and is honestly the main reason I bought it, but the impacts are both more precise and repeatable between screws. It feels like my old Makita just “goes ham” and makes a racket, this M12 Surge quietly cranks out precise repeatable and powerful blows. It feels more smooth premium and controlled. My favorite features are, in order: the quietness of impacts, selectable speed, one handed bit chuck, and precision/premium feel of using it day to day. I’m really happy Milwaukee is still giving their m12 line some love as not everyone needs the power and increased weight and bulk of 18/20v lineups. Overall this is my new go to for driving screws and such into anything as it’s honestly just satisfying and easy to use. The price is actually pretty fair considering I’m usually a value shopper and don’t buy new. I’m impressed and hope to get a long life out of it. I feel and see no reason why it wouldn’t last, and if it somehow doesn’t I like this enough I’d consider purchasing another if that day comes. ... show more

Just Buy It!
I have a Milwaukee 1/2" drill & driver set. The do very little since buying this. I love it. Its powerful, quiet, compact and light. I kept telling myself that my current set was sufficient, but the Surge is my go-to now and the others are my backups.

High power quality!
Professional use--automotive technician. I've beat the crap out of this tool (not on purpose) and it's my go to. It has tons of power for such a small unit when paired with an adapter and is light is versatile. This "SURGE" tool hits hard and is great to use for any of my jobs big or small. Only "complaint" is the light could be brighter. Amazing price too, comes bare tool but any Milwaukee or equ. M12 battery will do the work. ... show more

Another great Milwaukee tool!
Great milwaukee tool as usual for milwaukee. Not as much torque as the solid mechanical internal anvil based driver but smoother and much quieter. Small and compact for comfort. It definitely has its place. Battery life is pretty much the same. I can see tool longevity being something to note given the smoother delivery of torque but time is the ultimate test. That being said I use mine every day for work and alot! ... show more

Most ergonomically designed driver on the market
This is by far the most compact yet powerful, lightweight driver that I have purchased. High quality and a great value.

A little beast of a 1/4" impact
Small in size and voltage only, the Milwaukee M12 Fuel hydraulic impact makes less noise and vibration than any I've ever used, yet delivers performance on par with some 18V units. A brushless motor means one less maintenance item to worry about, and its efficiency keeps it running long and strong. Even the smallest 2.0 Ah battery has lasted me through a full day of screwing drywall. It won't break loose the lugnuts on your vehicle, but it will deal with most automotive fasteners encountered in typical maintenance and repair, making it versatile well beyond driving screws. I expect this will be the last one I ever buy. ... show more

Best all around impact driver I’ve ever used
I love this thing. Light, battery lasts a long time. I’ve never heard an impact driver that’s more quiet. It can spin fast enough and smoothly enough for my 1/4” drive step drill. Tons of torque for all the equipment hardware I use it on. If I were to have a single power tool around the house, this would probably be it. I use it for laboratory equipment repair on a daily work basis, and it’s overkill for most tasks. Also the quietness is incredible helpful in an office environment. ... show more
