1" Impact Wrenches

[JKady]

Finding myself increasingly wishing I had one, pops ain't about to let me take his to work. It's almost exclusively for removing tires and wheels on 2 ton and up trucks, shop has a 3/4" gun but it's got less guts than my 1/2" gun, and I can always adapt down so why not go big? I need something with an extended (6") anvil and would prefer a side handle since no inch gun is particularly light.

What's the hot ticket for something like that in the $500 range? Been looking at the IR 258B-6, CP 7778B6, and Aircat 1900.

I have been very satisfied with my CP 7778B6. We used it on Class 8 dump trucks/trailers and rock quarry equipment for years without any problems. Very powerful.

I have an old IR 271, 1" gun. I have it because it didn't work and I got it for $60 at an auction. Cleaned and lubed it and it's fine, but 1" guns are kind of pointless if you ask me. If you buy yourself a newer 3/4" gun with more "modern" specs (higher torque outputs,) you'll probably be more than happy. It's also easier to find 3/4" sockets than 1", in my experience.

This is what I bought used from fleabay.

For the price, I've got one of these at work and I love it.

Hard to find enough compressor to run it tho. Also, I don't use it but a few times a year.

You can't always adapt down. If the gun is too big to get around obstacles to get onto the nut, there's no adapting it anywhere.

You can almost always adapt up, but then there's the question of the power of the gun. I've adapted my 3/4" gun up to 1", it has never failed to bust loose a fastener, and my gun is not a name brand, or even a top tier gun.

You really need a good 3/4" gun before you need an inch gun. You don't want to be hauling that big heavy beast around for everything that's too tight for a 1/2" gun when a 3/4" would have gotten the job done.

How long have you had it?

I've had my eye on that one. I just can't bring myself to spend for a 1" one until my 3/4" fails to turn a fastener at least once.

Good item to try to score from a pawn shop.

About two years now. I am serious, I really only use it a few times a year, removing foundation bolts. It does it, where (at best I recall) the last time I tried was with a 3/4dr breaker bar with an 8 foot cheater and three of us on it and we couldn't for the life of us break it free, and that thing did. Ran it for about a minutes, let the compressor build back up, go at it again, and then run it off. So very nice.

i got one listed for sale on here if your looking

A 3/4" gun with any more torque than my 1/2" is the same or more money than the 1" guns I'm looking at, and it won't have an extended anvil. Ever removed a 16" dually wheel with a non extended anvil? It *****. I know what I want, just don't know exactly which flavor... I appreciate where you guys are coming from, but you're side stepping the question asked to answer one that wasn't. I'm asking for feedback on the gun models listed.

 

[Provincial]

Don't gripe at me - I answered your question!

On another note, I have seen extended anvil 3/4" guns for sale, but they are not common.

I agree that when it comes to heavy truck lug nuts, bigger is better. And you never have a situation where the 1" gun is too long to access the nuts!

 

[davesnothere]

I've been happy with the IR 1" impact.

 

[KinzeMech]

Ever removed a 16" dually wheel with a non extended anvil?

Yes. Extended anvils are one way to do it. Impact extensions are another. If it's going to be a single purpose gun, the extended anvil is probably the better way to go. If not, an impact extension delivers almost the same torque.

My apologies. I thought I was sharing relevant information. I read too fast and missed the part where you want to use it exclusively for busting wheels. I meant no offense.

I've used the CP 7778B6 as an employer supplied tool that has been used and abused by different people and they survive a lot of abuse and the design has withstood the test of time! The repair parts are also readily available. I don't recognize the IR258B-6 model--could be wrong but think you mean IR285B and it is almost a copy of the CP--stands up to all kinds of abuse! I've never used Aircat impacts some mechanics at work have smaller drive models and they love them. If you're going to do mostly tire work you should consider the #5 spline drive anvil models, most semi-truck tire shops use these.

 

[mdnelson86]

I agree with possibly looking for a good 3/4 impact instead of a 1" mostly due to weight and clumsiness, but I understand your need for the extended anvil and it seems like you've made up your mind on looking for a 1" gun and that's your choice.

The question I have though is when you say the shop has a 3/4" impact but it doesn't have the guts of your 1/2", is the 3/4 just that old or cheap that it just plain doesn't have the power? Or do you have a substantial enough air supply to properly run the 3/4" gun? They take a fairly significant volume of air to run right and I'd hate for you to get a 1" gun and then not have the air to run it either.

 

[Provincial]

You cannot get any power out of a 1" gun unless you have 1/2" lines/hose all the way to the gun. Even a 3/4" gun will not put out full power with 3/8" lines/hose.

If the hose is long or restricted, you may have to have higher air pressure at the regulator in order to get a full 90psi at the gun. Some people blame the gun for lacking power when it isn't getting enough air.

 

[JWILL]

if your set on buying a 1" impact gun and not a better 3/4 gun than the shop has. Then I would buy that HF gun for the money it should do just fine till your ready to drop the money on a bigger gun. The shop I work in has ****** 3/4 guns but we have an IR280 its pretty boss. However an IR293 would really give me a chubby. We use our 1" all the time and most of the techs own their own 3/4 guns. i just recently bought an IR259 and love it.

The 3/4 runs on a 1/2" hose, but it's a shop gun. I'm the only one who ever oils it, I can assure you the hammer mech has never been greased or cleaned, and it's very old. The thing is just beat, boss doesn't feel the need to buy us good versions of things like this if we already have one. I have my own engine hoist and stand there, and some specialty tools I've bought or made for the same reason.

We run more like 120psi but volume in the compressors is a bigger problem than pressure.

 

[kmkalf]

at our shop we have all IR 261 3/4" guns, they are indestructible and take off class 8 wheel nuts with little issues. they are pricy but worth the money

Having repaired the three you are looking at (and a lot of others) IR and CP give the best bang for you buck.

what size is the shop compressor(s)? you're exactly right that volume can be the bigger problem than pressure. I can run my 2 gal pancake compressor at 120 psi but it won't run a 3/4" or 1" gun.

At my shop, we're running an 80 gal Quincy QT-5 through 3/4" lines then 1/2" couplers through 1/2" hose to my 3/4" gun. Will take off any lug bolt I've tried with ease (deal mostly with big tractor tires and other Ag equipment)

I know plenty of guys who are running 1" lines or bigger in the shop as well. I'm still concerned that the shop doesn't have enough air to run a big gun effectively I guess. 3/4" or 1" doesn't matter.

 

[JackB]

I doubt you will have any issues with the compressor. The big impact guns use less air than random orbital sanders for example, and you're not running an impact gun 100% of the time, like a sander.
