#4437657 - 06/21/17 01:52 PM Best Impact Gun for removing rusted bolts

After struggling for four hours yesterday removing rusted bolts on my car using hand tools, I've decided that it's time to make a tool upgrade.

I have a 5 gallon Craftsman air compressor for an air source. I've also seen battery-powered impact guns, but don't know too much about them.

I need something that can remove a rusted bolt on a car driven through 10+ northeast winters. I guess the higher the torque rating, the better? Keep in mind I snapped an adapter as well as a socket yesterday just removing the wheel lugs.

School me! I'm not looking to spend a fortune here, but I saved a few hundred bucks doing the labor myself, so let's use that as a budget.

Thanks!

The harbor Freight Earthquake impact is a great gun for the price. I use one daily. But you need a bigger air tank.

I would make sure the compressor is NOT too low of a cfm to work the air tool.

Is there an electric one that would work that runs on a standard outlet?

I know a few people who have the 1/2'' drive harbor freight electric impacts. They seem to work good for what they are (low rated capacity).

PB Blaster is a good start. I didn't see that mentioned in the OP.

I have a DeWalt 1/2" electric (corded) impact gun I use for 99% of rusty stuck bolts. Bought it rebuilt off ebay for under $80 I believe. I have a Craftsman air powered impact for the big stuff, but that has only happened a few times. The electric works awesome and eliminates the whole compressor need.

Hf earthquake stood up to semi truck repair ,it died under a 100ton press that leaked down lol....
Milwaukee m18 fuel 1/2 in drive battery impact is one bad boy , buying that is cheaper than buying a new compressor and their batteries work in a variety of tools

FWIW, the 5 gallons compressor is too small.

Check Youtube on how you can expand the compressor capacity with additional air tank.

Or you can buy a 20 gallons compressor from HF.

There are also a lot of used IR Impact Wrench on Ebay, once in a while, you will find an unknown IR model that nobody's bidding.

I have a Harbor Freight Earthquake impact that I bought about 13 years ago. Has been a great impact. Just recently replaced it with this one
http://www.homedepot.com/p/Husky-1-2-in-800-ft-lbs-Impact-Wrench-H4480/203458750
Gotta say that the Husky one is just a bit better than the Earthquake. Cannot comment on the new generation Earthquakes though. The one I have is a different design. Butg I highly recommend both

There are, I have one from Canadian tire, 7 or 8 amps and 280-300ft-lbs. Any lug I've tried isn't making it work at all, and it took off some big pinch bolts off the struts on my old Neon with a couple of second of back and forth.
Electrics are big and heavy so not ideal for under the hood stuff, but for lugs and the odd job, they do work.
I haven't had the desire to get anything better anyways.

My Milwaukee 18v FUEL series impact has been amazing.

Rips through crank bolts, CV axle bolts and whatever else I've thrown at it; sometimes without a fully charged battery!

I have an old Japanese made Ingersoll Rand 1/2" impact at home. It's not the most powerful impact. I cranked up the PSI higher on my air compressor
doing a timing belt job. The crank bolt wouldn't budge at the factory setting of 125 PSI, it did at 140.

A good start to getting loose rusted bolts as someone stated is to start with some penetrating oils. PB blaster or home brew of ATF with acetone and some heat(heat first or the resulting fire will remove the whole project:)) goes along way
