When the V28 line of Milwaukee cordless tools first came out, we had a customer come in and wanted to see if the impact had enough power for the lugnuts on his brand new dually. It’s listed as 325 ft-lbs of torque, but what does that mean when you’re using it? We had a battery charged up, so we took it to the parking lot to see what it would do.
Removed the lug
It removed the lug nut just fine. No problems at all there. In fact, it didn’t even seem to think twice about this simple task. The V28′s have more than enough power for pulling off a lug nut.
Installed the lug
It didn’t have any problems when installing the lug, either. It tightened it up in no time flat, and it gave a couple of clicks so we knew it was tight. That was the point he should have stopped.
One more time
The customer pulled the trigger once more – just to make sure it was tight enough. Well, that was one time too many. He managed to shear off the stud with that little pull of the trigger.
Bought the tool
He was impressed with that, and bought it immediately. He didn’t need any more proof that it had some power. The funny part is that relating that story to people in the store, many immediately say “That’s the one I need then”.
How much is too much?
That brings up the question – how much is too much? I don’t personally need to shear the studs off of the wheels of my father’s Jeep to know if something has enough power to put a lug nut on or not. I don’t need the most powerful tool on the market. The jobs I do never require the biggest, baddest, meanest tool in existence. I’m usually just driving a screw, setting an anchor, or changing a tire. Even some of the much lower voltage tools can handle those jobs without much effort. But, being Americans, we feel inclined to buy too much instead of what may only do what we need. I’m sure someone will come out with a 350, 400 or even 500 ft-lb impact at some point, but what’s the use if it breaks everything you’re trying to assemble?
