1/2 fuel milwaukee vs 3/4 impact.

[Hammell]

So im impressed with reviews on the Milwaukee 1/2 fuel impact. 700ft lbs working torque and 1100 ft lbs reverse. Im definitely thinking of retiring my old 1/2 impact Milwaukee non fuel model as it is getting tired. It has been very reliable for 5 years of daily use.

But in real life, is the fuel going to be actually as powerful as my 3/4 impact, (cp772h) which is also rated for 700ft lbs working torque and 1000ft lbs reverse. I work on earth moving machines, track pads, tight sprockets, rollers, and cutting edges, usually1 7/16, 1 1/2 size nuts, torqued to about 500ft lbs. Is the Milwaukee fuel really going to be able to undo these bolts, or tighten them? Or get them close? I always go over with torque wrench anyway for insurance.

I'm gonna say your 1/2 Fuel will do 95% of what that 3/4 impact will do with ease. I've owned mine for over 2 years now and it has rarely disappointed. As a Millwright I work on industrial machinery for a living, the most recently I removed some 1-1/2 bolts off of a huge gearbox, regularly torqued to 800. Needless to say i was impressed.

I have a 2763, and there are times that I wish I had the 3/4, especially when adapting up to 3/4" drive sockets anyway.

I recently purchased the Dewalt Dcf899 impact. It has 700 ft lbs working, 1200 break away and it is an absolute beast. Then I have a 3/4" Aircat 1600th pneumatic impact 1200 ft lbs working and 1400 break away. There's no comparison. The Aircat is a lot stronger. On another note, I'm considering selling my im6100 and mg725, while only keeping the Dewalt and Aircat. I've not had to use my 1/2" pneumatic impacts since buying the Dewalt, but have needed the Aircat. I realize my tools specs are different than yours and never used the cp772h, but I think the 3/4" will still be a bit more powerful. I'd agree with xela456 and bet the Milwaukee will do 95% of what the 3/4" will do. Those aren't huge numbers on your 3/4". After you get the Milwaukee you should consider picking up a larger 3/4" impact. I really like Aircat line of air tools. They're tough as heck, strong, reliable and CHEAP.

woodstockva (a member here) has tested all the modern brushless 1/2 impacts. He owns his own Skidmore torque testing device. All of the big three brands, red, yellow and grey are very close in total torque numbers. If I remember correctly, the yellow impact wins by only 12 ft lbs. Not enough to say its a clear winner, and certainly not enough to say it's "better" than the others. Red came in second place..... and considering their tool line-up compared to any other brand makes red a clear winner to me.

And to answer your question directly, if you're trying to break lose a fastener that only requires 1000 ft lbs (give or take) then any of the 3 will probably do the job. If the fastener requires more torque, then you will need another (bigger) impact. Of course this is in a perfect world..... charged battery, with no extensions or drive adapters.


Edit: After re-reading you post..... if you're using 1 1/2 inch (inch and a half) sockets, then you really should buy the 3/4 version of brushless impact. Woodstockva did a test video that shows just how bad even one extension or drive adapter can KILL the torque from an impact. So yeah, if you buy the 1/2 brushless, then put a 1/2 to 3/4 drive adapter on before the socket..... it will NOT perform like your 3/4 impact with similar torque specs. If you use a drive adapter, you WILL be disappointed. In your case, buy the 3/4 brushless impact.

You might look into the new makita cordless impact that's available in3/4 aswell and strongest cordless impact available now not sure part numbers but the is a video on realtoolreviews

And to answer your question I would not have a cordless replace air even thou specs are close air will be constant

Wow. What do you use to torque it with? We have a device that has massive flanges and a BX metal seal that needs to get crushed. We can never get it torqued correctly by hand. The seal is like new when we take it apart. I saw some impressive hydraulic torquing tools at OTC yesterday but the opposite side needs to be held snug to resist that opposing torque.

700ft lbs working torque and 1100 ft lbs reverse.

I think you're getting your number confused. The 700 is max torque, the 1100 is "nut busting" torque. Two very different things.

i've got a cp772h as well as a cp8072, both 3/4 drive.

my milwaukee 1/2" definitely feels like it can hang with the big boys. i used to use them every day working on large ductile iron casting machines. and i'm using my 1/2 every day at work now doing repairs on 200+ Ton brake/punch presses, haven't found a 1" bolt or larger that it hasn't taken out in a few seconds.


yes, adapters and extensions kill the torque on even the big air impacts, so buy a set of 1/2 drive impact sockets that go as high as you do, and it'll be just as good.

So whats a cp8072 have for torque?
