I wrote a post a few weeks ago, about getting a cordless impact
wrench
for my vehicles, as a back injury overseas, has made things difficult
for me.
I wound up with the dewalt 12v, 1/2 inch unit.
I have had very positive results.
The formerly useless rusted on lugs are finally free.
I heavily sprayed once again some wrench brand penetrating fluid.
I waited about ten minutes, and banged each lug a few times, and
repeated the lubrication liquid again.
I waited another five minutes and tried to free with a cross
bar
wrench, with a long section of pipe for leverage.
No dice.
I put a regular sized 21mm impact socket on the impact wrench and
applie the trigger at first slowly. Nothing going on.
I pressed the trigger down all the way, and applied a bit of
forward
pressure, and after about four or five seconds the lug zipped all the
way out.
Okay I said, lets see what happens.
All the other lugs came out the same, with the exception of one
lug. I
changed to a deep socket and that did the trick.
I cleaned off all the exposed metal, and using the wrench, gave a
light
tightening for a half second, and tighented to specs using a manual
torque wrench.
I am glad I got the wrench.
I went to rotate the tires on my xterra(which I could do with a
regular lug wrench), but using the impact, saved me a lot of wear and
tear and time on my back, and was a joy to use.
Net effect, I made a good decision and the tool, proved to get
the job
done.
I leave the wrench in the trunk of the car, and will change
the
battery out every month.

Much regards




With a 12V unit,I wonder if you could get or make an adapter to use the car
battery for power? (use a heavy 2 wire zip cord;14 or 12 ga.)

then you don't have to worry about charged battery packs.

BTW,hot environments discharge battery packs faster than normal.
Like the inside of a car on a sunny day easily gets to 140 degF.,NOT good
for your battery packs.
