Not sure I've posted about a new love for Milwaukee-brand cordless tools but after this weekend its a love so deep the current girlfriend is "concerned" about me!
Specifically their M18 volt impact guns are amazing, battery life is beyond "useful" and the power simply astounding. I had occasion to remove, lightly oil and retorque all 32 lug nuts on my 2005 E-350 extended body. I fully charged three M18 batteries, not knowing how quickly they'd last on this chore. I was using the 2767-20 hi-torque 1/2" friction ring tool, a 140 Ft/Lbs torque stick and dedicated torque wrench to assure the correct setting was achieved. For the most part the torque stick is spot on.
This impact tool has a torque mode that allows the tool to initially produce its full torque removing a fastener---full speed available via the trigger. When the tool senses a loosened fastener it slows down considerably no matter where the trigger is set. In the case of lug nuts this mode keeps them from flying away when they're completely free of the wheel stud.
After lightly applying 3-in-1 "light machine oil" to the studs and a dab inside the lug nuts I changed tool modes for max torque (1,400 ft/lbs
) and using the torque stick lugs were set. As I said I did verify the correct torque and it was right on 140 ft/lbs.
The battery I used still
has all 4 "fuel gauge" bars showing which is another astounding quality---after R&I'ing 32 lug nuts.
In addition to that behemoth 1/2" 2767 I have the 3/8" (#2754) version which is equally amazing for its size. It will remove the lug nuts but takes a bit longer to break them free. It wasn't use for this project so I have no idea what real final torque it will deliver------claims of up to 210 Ft/lbs are made.
I bring this up now because for a pack and go tool that has amazing battery life when just sitting they're infinitely handy for tire swaps etc. They're also "small" and stow very well, taking no more space than conventional tire tools. Mine tend to ride under the fixed base factory seat up front in a tool pouch that includes the deep well socket, 5" impact extension and torque stick.
Along with the Hummer jack and adapters many of us carry these days an impact might be the perfect tool for highway tire work. I'm a true Miwaukee fanboi but honestly most any 18 VDC tool would probably work just fine.
Something to think about perhaps......................
