I'm not a professional mechanic but the Milwaukee M12 stubby 1/2" impact wrench has greatly improved my home game wrenching. I was struggling to remove a 19 mm crankshaft pulley bolt on my 1996 Daihatsu Hijet mini truck using various hand tools and wasted 45 minutes with no success. I bought the M12 stubby impact and used it on the lowest setting and it didn't quite remove it. It may have if I kept trying for a minute, but I bumped it up to setting 2 and that stubborn bolt spun out immediately. Super easy!. Barely an inconvenience. All of the torque I could apply with a breaker bar was only turning over the engine or rolling the truck if I put it in gear, even with the emergency brake applied. The hammering impact works where constant application of torque doesn't. It's a real game changer, and the stubby size easily fit between the pulley and the radiator on my mini truck. Only a 90 degree impact wrench will fit in tighter spots, but this little impact wrench has the torque to take off lug nuts with ease. With great power comes great responsibility. For those new to impact wrenches, start on the lowest setting and always check that it's in reverse to avoid snapping bolts when trying to remove them because this wee beastie will rip the heads off smaller bolts and strip threads if misused. Tools like this are obvious purchases for professionals, but for occasional home use, this well designed high quality tool is definitely a "buy once, cry once" tool that provides value measured in not busting knuckles, wasting time and putting money in the swear jar. With pretty good HyperTough cordless tools at a quarter the price, this M12 impact wrench is probably a luxury for home use, but good tools make you feel good. It made quick work of removing the bolts securing the water pump as well. This stubby impact wrench was the gateway drug that led me to an M12 addiction of ten tools and counting.

Great power for it's size. Plenty of torque for trailer lug nuts. It didn't want to do my F-350 lug nuts, but the dealer probably over-torqued those dramatically. Easy busts lug nuts that are properly torqued to 100 ft-lbs. Works good on camper scissor jacks too. I have zero complaints, a heck of a tool for its compact size. Only the toughest of jobs would require the larger impact.

Great compact 1/2” impact, battery life depends on the battery you run. It’s Milwaukee quality, great torque, it can bust lug nuts, motor mount bolts and mostly anything minus transmission bell housing bolts loose. I’d say it’s a good value for a Milwaukee branded product but you can probably get other products that’ll do the job, this one is better if you’re looking for a compact impact though.

INSANE tool. I have really put it through its paces and it out powers a 20v impact with EASE on the 2nd setting. I have removed the rustiest axle nuts, sway bars, lug nuts, axle bearing assemblies....this tool doesn't give a F what its about to go up against, it will remove it. I completely resold all entire 20v and 18v tool line up and now in the process of replacing all my tools with the full M12 Fuel setup. This thing is a freaking monster!!! Its lightweight, compact size, and I've shown it to all my friends as a bragging right. Just them putting it on setting 3 and pulling the trigger- feeling it twist in their hands, their eyes literally light up because they can feel the power it wields... Amazing job Milwaukee, I am a customer for life now. I never leave reviews unless something just absolutely impresses me- this is my favorite tool in my tool box, and gives me so much confidence.

Great impact. Poserful and small enough to get into spaces. Its got a lot of rough edges. I am buying one of the rubber covers to help it not catch on things under the hood. Three settings and a torque limiting setting.

just great product, lots of power, takes of lugnuts on any sedan really fast, milwaukee is obviously going to last a long time. very light for its power, and way cheaper than buying it from a tool truck. would recommend getting this with a high output battery and it will last a lifetime.

Came new in an authentic box. I work on cars all day long. Have had 0 issues with this tool if you use it realistically. Batteries are super important for this this tool. So make sure you understand that a 2.0 vs xc 4.0 vs high output 4.0 will have different results. This is my go to for lug nuts, brakes, suspension. Works excellent.

Definitally a solid starter for some lugg nuts and suspension, has some trouble getting off key lugs idk whats up with that, but anything past 130lb its gonna be having a rough time, if you do end up deciding to get this i would definitely get a 6.0 ah battery for it, dosent have to be a milwaukee brand, found some for 40 bucks a 2 pack and they sure do better than my milwuakee 3 ah batterys
