IR 2135TiMax vs. CP 7750

[BB26]

I am going to be upgrading my 1/2’’ impact from the trusty IR 231C to one of the following guns:

CP 7750: http://www.tooltopia.com/chicago-pneumatic-7750.aspx

IR 2135TiMax: http://www.tooltopia.com/ingersoll-rand-2135timax.aspx

Don’t get me wrong, I love my 231, but it just does not have enough guts for some of the jobs I run across. It will become my back up.

What do you guys think about the above guns? The CP is a little more powerful, but about a pound heavier. This is not too concerning as I do not use my ½’’ impact all that often. I usually use hand tools or my 3/8’’ impact. The main purpose of this gun is to tackle tough jobs. The CP can also be had for about $40 less. I anticipate most members recommending the very popular IR, but for some reason, I am leaning towards the underdog (CP).

Let's hear what you have to say...

 

[ImportTuner]

Sounds like you already made up your mind on what you want .. Both impact guns are excellent .. the IR having slightly more torque and a bit lighter ..

 

[BB26]

Not necessarily. I have been swayed from my original opinion by this board several times in the past.

 

[gofastman]

I second that. I would go for the IR due to the weight. If, for some reason you can't loosen a fastener with one, I doubt the other will knock it loose anyway.

I almost bought the IR but went with this NitroCat 100TC instead, very satisfied so far.

Those are good too, especially for the price, (I love my 1375XL, hardly touch my 2135QTiMAX anymore)
but that company flat out LIES about their products torque output!

 

[boogerboy72]

is their specs stated too high or low?

 

[rjohnson]

I can sell you a new in box 2135Ti (not max, but a great gun) for $225 shipped. Please pm me if interested, it's an extra-I love my everyday one, VERY powerful and light!

 

[gofastman]

Far too high, all company exaggerate their outputs, but Aircat's claims are ridiculous, my 1375XL for example, is advertised as having 700 ft lbs of loosening torque. Dont get me wrong its plenty powerful, but I wouuld say at most it has 400-500 foot pounds of absolute-fullbore-short socket-no extension-just oiled-running at 150psi-hammering for 30 seconds loosening torque

 

[wellstig1]

If your going the aircat route, this is the latest and greatest 1/2".
Seems to be as strong as my mg725, the lack of noise is cool too.

I have been selling these by the boat load. Super strong gun. Not bad weight. And a HELLUVA great price.

Got Blue?

 

[Skyline]

Isn't the CP now made in China?

I hope not. Anyone knowledgeable on COO for the IR and CP, speak up.

 

[rjohnson]

Well, the 2135Ti says "Assembled in USA".

 

[supertooljunkie]

I have an IR2135Ti and the only time it would not break a bolt loose, I had to put a 24" breaker with a 4' cheater on it. I broke the bolt.

I don't have any info on the CP, but I have no problem with the IR. Before that I had a Snap on 1/2. It was stolen and I replaced it with the IR and haven't been dissappointed.

 

[Marlin]

I hope not. Anyone knowledgeable on COO for the IR and CP, speak up.

The 2135TiMAX, 2115TiMAX and 2141 are all assembled in Athens, PA with many of the crucial internal and external parts also made in the US.

Thanks.

Does anyone have experience with the CP?

What's the difference between the Ti and TiMAX models?

 

[momswgn]

Been happy with my IR2135 Timax.

 

[supertooljunkie]

2135Timax 1,100 ft lb. max rev. with 780 ft lbs. working. 500 ft lb. forward.
2135Ti 1,000 ft. lb max rev. with 700 ft lbs. working.

 

[Flash21]

Happy with my 2135Ti and my 2115QTimax!

 

[kmorgancraw]

The IR is actually more powerful for breaking things loose. I've used both guns back to back on the same job and the IR is more powerful, no doubt.

 

[ukvauxtech]

The ir is the way to go. No question.
I have one and it's excellent but generally i use my snap on 3/8 mg31 very loud but gets out virtually every bolt i put it on.
Just a thought....

Search the archives, you find plenty of threads about the IR 2135TI versus other impacts but, probably not the 7750. I've used the IR 2135 series since it first came out and have never been disappointed. I even bought a MG725 to see if it was better and I sold the MG725. Shop around for the best deal from internet vendors. The CP7750 doesn't have push button direction change. It uses a rotary knob to change direction and regulate power. I only use impacts with simple one hand push style direction changes. CP just released a new gun the 7749 that I saw at SEMA. It still wouldn't make me give up my 2135 series but, it's a good looking impact. Its grip is a little on the narrow side though but, it has push button direction change,and more power than the 7750.

Thanks, Fed. As always, you are a wealth of knowledge. I know there have been tons of threads on the IR, but I was hoping to get some info directly comparing it to the CP.

Thanks to everyone for the input. I will probably end up going with the TiMAX.

 

[Fedwrench]

Thanks to everyone for the input. I will probably end up going with the TiMAX.

A further recommendation would be to get the Quiet version. I have both and the TIMAX is pretty loud. It's worth the extra money especially if you work at home and have neighbors.

Neat. As soon as I saw that, I was thinking "that's the only air gun I've seen with a side-to-side direction switch like electric guns". Then it says right in the description that it is the first 1/2" gun to have it (where there other sizes that had it?).

I was thinking of going with the IR (or the Matco rebrand of it to match my 3/8" MT2120) but now I think I will get the CP!

 

[IRMan]

Thanks.

What's the difference between the Ti and TiMAX models?

I have repaired a few of those CP 7750's they are a unique impact thats for sure and I cannot say anything really good about them.

I also repair IR and the only differences between the the Ti and Timax is the cylinder has 3 exhaust ports instead of 2 that the older IR composite impacts have like the 2131. And also the housings seem to be either gray or black, I think the newer ones are gray but the replacement housings we use are black?? Doesn't really matter because they are both identical.

I will also share : the Q models "quiet" that they charge like 100$ more for are only silenced by a few pieces of cloth/foam. 1 piece covers the exhaust ports on the cylinder and then the inlet bushing has a plastic piece molded for a piece of foam that is simply held on with scotch tape :/

The suckers are a lot quieter and only loose a couple ft. lbs. of torque.

Since I have no care to comment on the CP7750, the CP734H 1/2" is a good contender to the 2135 but is much smoother with its oiled clutch vs. the IR's twin hammer setup but is much heavier

On the other hand though. we got one of those nitro cats in and it put out more torque than both the IR and CP's I was a little shocked lol. The only problem with the nitro cat is replacement parts.

hope my .02 cents helps someone

I find that hard to believe, not saying you're a liar though. I have use the nitrocat and the it Ti guns back to back and the ir appears way stronger. Perhaps the nitrocat's pin clutch mechanism delivers more torque, but the higher number of blows per minute with ir's twin hammer setup can bust loose a tighter fastener

Which model nitrocat btw? what were the testing conditions?

 

[jteck75]

My snap on 725 was destroyed in a fire and I replaced it with this gun from napa,I loved my s o gun but when you have to replace about 40% of your gear in one lick you have to get what you can get. Anyway I've been plesantly suprised with this gun.

[LGMechanical]

I would suggest the MG725. Strongest and toughest 1/2" impact wrench on the market!

According to snap-on's advertising department. They forgot to mention one of the loudest and most expensive too.

expensive yes, loud yes. worth it? YES!

Not exactly sure on the model off the top of my head but it had the flame job on the hammer case.

This is how we do torque testing

We have 2 bolt tension testers that measure "bolt tension in pounds"
The smaller tester goes up to 30,000 and the large goes up to 170,000

For 1/2" impacts we use the small tester with a 7/8" bolt head. Since we use the same air regulator for both stands the air is normally set to 120psi ( which has sheared rotors on the 2135 . So the testing is done around 100psi 90-120 depending on tool.

The conversion we use are

7/8" - Take guage reading of bolt tension in lbs - 2135 gets around 25-28k
so I take the 25,000 and divide by 105

25,000 / 105 = 238~ft. lbs

on the 3/4" and up we use a 2 3/8" bolt head and divide the results by 60 for foot lbs.

The typical IR 261 gets around 80-90k on our tester
85000/60 = 1,420 ft. lbs

The tools are ran until max torque is achieved.

That nitro cat maxed out our small tester at 30,000 in a hurry!
30,000/105 = 286 ft. lbs.

The IR's are great if well taken care of but I only average 240 ft. lbs with them but thats on our tester, not sure how close to accurate it is but we have them callibrated every year.

EDIT : All torque readings are in fwd only. Do not have a tester to guage reverse torque

Just a couple of things to maybe help with any confusion. 1) The 2135 series is a reverse biased tool, when you bias a tool you purposely give up some performance in forward in favor of gaining more in reverse where it is most needed, if you're not running in reverse you are not measuring the max torque. 2) Testing should be done on the larger size tension tester, the 2135 can yield the 7/8" test bolt on the Model J skidmore(I assume that is what you are using) 3) Using a conversion factor may not give you accurate results because it assumes a correction factor based on friction in the joint. To really understand the torque achieved you can measure the torque required breakaway the fastener in the tightening direction

Correct, we have a model H and J - J being the 7/8" bolt. I'm confused on "To really understand the torque achieved you can measure the torque required breakaway the fastener in the tightening direction"

Are you saying to get a torque wrench to test the torque on the bolt? Please share more! I would really like to get the most accurate results but able to do in a timely manner. I just use the conversions like they tell me to do

 

[Marlin]

You got it, just use a torque wrench to see how much it takes to move the nut further, but on the larger Skidmore/bolt you need a good size torque wrench. If you're trying to gage performance after a repair and you have a good reference tool then what you are doing is fine. I'm just trying to let you know how the torque ratings are arrived at.
