I bought
this, its a Milwaukee tool battery powered 1/2 inch impact driver.
It's from their "Fuel" line, which is their marketing for versions with brushless motors.
It's a bit pricey ($400 -ish), but it is AWESOME! It puts out up to 1,100 Ft-lbs of torque to unscrew items, and up to 700 Ft-lbs to tighten!
(Yes... you read that right!!!)
It's changed my life in terms of working on the truck. I didn't know this before,
but with an impact wrench, you don't experience torque in the tool handle like
you do with a regular cordless driver drill.
I personally bought a set that came with a hammer drill, a bit driver, a charger
and two of of their "XC5.0" batteries --- which is their jargon for 5.0 amp hour extended capacity batteries. They also offer XC4.0 batteries (4.0 amp hour).
Then I bought the impact driver separately as just the driver without a battery, or charger.
At the Home Depot had a promo where if you bought one Milwaukee cordless tool, you got up to $150 off another, so the full set... three tools, two 5.0 batteries & one charger ran me $550.
Not cheap... I know... but this is WAY better than the Ryobi one+ stuff.
I've had the Ryobi 1/2 impact driver for several years, and it just doesn't have
enough torque... The Ryobi one is only rated for 200 ft-lbs of torque, and their ratings might even be optimistic... For example, I have NEVER been able to take off lug nuts with the Ryobi driver,
and the Ryobi driver has been useless for freeing up tight bolts, but with the Milwaukee Fuel 1/2 impact driver, I feel like I'm part of a NASCAR pit crew!
Also note that the tool comes in few different versions. For example, you can get the anvil with a small ball bearing to hold the socket on, or a detent snap ring. Also, the models have a low and high power mode, and the torque on the low power mode differs based on the version... just an FYI... the folks at the store where you shop probably won't be aware of these difference, but you can read about it on the company's website.
The Milwaukee Fuel 1/2 impact driver is truly professional grade. The batteries last a long time before recharging, and they are more powerful than some of the air-driven impact wrenches.
I posted this because, so far, I've been able to effortlessly break free all of my stubborn bolts. Squirt with penetrating oil. Let it sit. Then use an impact socket (black not chrome)... the impact sockets give a little more... the chrome sockets are too brittle. Also a trick that I've been using... I bought an impact rated short extension and an impact rated 1/2 to 3/8 reducer (both black)... along with an
impact rated 1/2" universal joint.
I use the extension (and reducer when needed) with my regular chrome sockets. I figure the extension is the right kind of metal to help absorb some the impact force, so I'm less likely to damage my regular chrome sockets.
For sockets, I bought an inexpensive set of metric 3/8" impact driver sockets from Amazon. It's not everything I need, but it's a start, and I use my regular chrome sockets with the extension when I need other sizes.
I suppose you could (and might) break off the bold head if it is really frozen, but you also might just bust it free. It's been such a good change for me.
Also, use caution (and the lower torque settings) when putting bolts on with the driver. Torque them down by hand, or be very careful or you will over-torque, or even snap off your bold heads.
One more tip... I also bought
these off of Amazon. They are "Heavy-Duty Torque Stick, 1/2-Inch Drive Extension Bars 65 to 140 Ft Lbs - Chrome Molybdenum".
Basically, they are extensions that flex when you hit a pre-specified torque setting. If you go slowly when tightening with the impact driver, you can use these to torque bolts to an approximate range. It's not exact, but if you don't normally use a torque wrench, then something like these are way better than nothing... plus they are convenient.
Sorry 'bout the long post... but I thought I'd share. It's been that helpful to me, and seemed to be on point re: freeing a stuck bolt. :heh:
