I have been looking at Dewalt and Milwaukee units on-line. While the Dewalt has more torque (300 ft-lbs) the Milwaukee has variable speed (240 ft-lbs). Both should have enough torque for the Miata, but I an concerned about spinning off the F250 lugs (150 ft-lbs).

Any experience with these units?

Any other ones to consider?

Hi Steve,

We have the Milwaukee unit. I don't know what others' experience is, but I've founf that it's useless for breaking lug nuts. It'll do the car once, maybe twice, and after that, the batterites don't have enough juice. Now, we break them by hand with a spinner while the car is down, and then use the gun to quickly spin themoff and then back on.

I've had great luck with the Dewalt unit. I use it all the time for lug nuts, and I've used it to break axle nuts free no sweat. But, like the Milwaukee unit, the battery really has to be topped up to get maximum torque. You notice it right away when the battery starts going south, it'll struggle with the lug nuts.

I have the dewalt unit and it works great....

I do need a crane to list it out of the case and over to the car though!

I highly reccomend the Dewalt, but have no experience with the other unit you list. I have the slightly lower model 18V Dewalt that does 98ft-lbs:

For me its perfect because I need to torque to 100ft-lbs and 98 gets me really close and then its a quick job with the torque wrench to get it perfect. I'm not sure I'd want the larger 300ft-lb one for fear of over torquing. Even though its rated for 98 it does easily remove the lugs which are always at least 100ft-lbs.

The kit came with two 18V batteries but I've yet to need the second battery at a track event. So far I've done two full tire swaps on one charge and think I could have done at least a third. DeWalt batteries are awesome - I own many of their 14V and 18V tools. The quality is top notch in my opinion, and although I do take care of my stuff, I have tested their durability. My basement flooded a few years ago and some of my DeWalt cordless tools were underwater for a few hours. I let them dry out, sprayed them with wd-40 and they are still going strong today!

For kicks and giggles I bought the Cummins travelling tool show cordless impact. They claimed something north of 250 lb/ft. I brought it to my shop, bolted on a wheel and torqued it at 80lb/ft. Do you think the gun busted that nut?... Cummins has a very good return policy as long as they are still in town...Dewalt has been great, but will struggle with 100lb/ft after 8 tires are done on 1 battery.

Isn't the newest Milwaukee a 24 volt?

I've been using one for a year, it's worth every penny (I swap wheels a lot and I'm usually pressed for time). Recharges in ~ 1 hour, will handle 3-5 sets of wheel changes on a charge. The deWalt, Snap-On and Milwaukee guns are better but you can buy five of these for the same price. . .
