Milwaukee Right Angle M18 Impact Wrench Model #2668

[dnschmidt]

I love Milwaukee and I do like the two 2668 that I own. However, there is no way in hell that these things will torque up to 60 ft-lb which is the rated spec. I've done extensive testing on the two that I own and 30 ft-lb is the maximum these tools will get to. What I did was take one of my wheel lugnuts loose and then tighten it to 20, 30, 40, 50 and 60 ft-lbs. using a calibrated digital torque wrench which I absolutely know to be dead nuts accurate. Absolutely no go after 30 ft-lb when it came to removing the lugnut.

The tool has value as it can get into tight places but it's an absolute lie that it will torque to 60 ft.-lb.

Did you switch it to speed 2? Speed 1= 30ft/lbs Speed 2=60ft/lbs.

battery fully charged ?

All the above. Also used the 4 Amp batteries on both and they were fully charged. The simple fact is that they top out at between 40 and 45 ft.-lb. (which they can achieve after about 10 seconds on impacting if you're willing to wait that long which I certainly am not) which isn't the end of the world but isn't 60 either. This is a nice tool but Milwaukee shouldn't make claims that aren't true. If it maxes out at 45 ft. lb. that's what the spec should be. I know for a fact it sure isn't 60.

There's a thread somewhere around here about impact wrench torque. I think it had something with the Milwaukee 2763 impact wrench not putting out 100 lb/ft in mode 1.

someone mentioned that there is a greater clamping force on a larger bolt torqued to the same setting as a smaller bolt......I think that's right.

try the same procedure on a smaller bolt. I think someone called Milwaukee and asked what size fastener they used to come up with the torque rating.

For me personally if I a company claims a certain rating that is usually done in a certain environment under certain circumstances

We live in a real world with real world results

I have to agree OP. I've done no testing but everytime I've pulled out the tool it hasn't broken anything I've asked of it. I figured I was just asking too much, but the fact remains it's not a useful tool for me.

The initial theory was that the low profile head limited torque, but the AC Delco puts out a claimed 100 ft lbs and uses the same head (as does the Hitachi according to Woodstockva).

Discussion of the heads here (last 2 posts). Also Makita uses the same head apparently, I had forgotten Woodstock listed them as well

and I mis-spoke, AC Delco claims 95 ft lbs, not 100.

Ironically when the Milwaukee first came out my position was that 100ft lbs would be just about perfect, 60 seemed too low to be all that useful, and after reading the OP's information in this thread I'm also wondering if the Milwaukee is even capable of 60 ft lbs.

edit: the Makita only claims 530 in lbs, so 44 ft lbs? Damn. Of course maybe that's what the Milwaukee is truly putting out!
