corded impact wrench

Strange to me that one of these is rated at 1050 ftlb, while the other is only 300. Yet the power requirement looks like 1A different.

I bought a corded impact as my first. It was ok for lug bolts but was pretty weak. The battery operated units are far superior of course.

I’d give the old Craftsman air impact a try on something first. Verify its specs.

Definitely get the heavy wall socket too.

Both the Milwaukee and the Bauer in the links I included are 300 FT/LB. The Bauer list 1050 break away torque, the Milwaukee does not give a spec for breakaway torque.
I will probably try the Craftsman first. I do have the Lisle socket ordered.
I did find a Kobalt corded impact and at least one video of it breaking loose a Honda crank bolt.

Oh ya. Neither of those will touch a Honda crank bolt. My IR231with unregulated 140 psi and a weighted socket won't take one off.

Yep, some of those bolts can be really stubborn. I have the special sockets for Honda crank bolts since a lot of my family/friends drive Hondas and I service them. The last one I did on a friend's 2000 1.6L Civic I had to go get a 3/4" air impact, my battery 1/2" Dewalt and my 1/2" Craftsman air impact wouldn't budge the crank bolt.

I did a timing belt on my sisters '80's something Hundog. Manual trans also, feet on brakes assistant in gear I still was turning the crank. Multiple 1/2'' impacts on a big compressor didn't' faze it.
Big Ridgid strap wrench on the pulley and big breaker bar was the solution.

I’m not sure where I saw the video, but the heavier socket has more inertia than a regular impact and made all the difference using the same impact wrench.

Buy a good cordless impact and use it for rotations, suspension work etc…I have an old Craftsman 19.2 volt with the old NiCad batteries and it was gutless. But I bought Lithium battery and charger off of Amazon and it really made a difference. I even used the impact to drive huge lag screws into really wet 6x6s for a dock project.

Not just more inertia, but less socket flex eating away at the generated torque

Breakaway torque is the most useless number there is, pure worthless advertising.

The corded Bauer from Harbor Freight made 610 ft.lbs of breakaway torque on the torque test channel. It made 568 or breakaway with a 50' extension cord. I only paid 60.00 which is the sale price for mine. If you want to see tests of all the various impact wrenches go here:

The cordless Ultra Torque Hercules impact wrench made it's 1200 ft lbs of breakaway torque. The Bauer referenced above advertises 1050 ft.lbs but only made about half that. Either way it is very powerful for the money and has a lot of good feedback from users.

I am thinking of getting this one, as my existing Chicago Electric corded impact 68099 was barley up to the task with respect to removing an axle nut. As in I thought I was going to destroy my Chicago Electric corded impact 68099 and want to pick up something substantially better when I see a sale so I don't potentially get stuck next time.

I had completely forgotten about starting this thread. I bought the Kobalt corded impact wrench and it with the Lisle socket removed the Honda crankshaft bolt with no problem.

I have that exact Bauer (Harbor Freight) electric impact wrench. I was drawn to it by the price, more than the immediate need. (That tends to happen a lot with Harbor Freight stuff).

No complaints thus far, but admittingly I haven't used it a hell of a lot either. But it seems to have good power. But Astro is right, the same thing in a pneumatic gun will outshine it.

I used it to drive the long 3/8" lag bolts through 6, 2" thick boards you see at the end of my, "Econo Ramps". They went in like it was warm candle wax. I didn't feel like buying threaded rod, cutting it, cutting counterbores for the nuts and washers, and all of that.
