Impact sockets for impact air ratchet?

[Trav]

Why? Its only got 50 ftlb of torque and also made in Taiwan, I don't see the gain.
The 1143 has 70 ftlb and made in Taiwan so that's a wash too. HF is not my favorite tool vendor but to be fair the Earthquake line seems to get decent reviews and seem durable enough.

It's fast! I've seen it in action on the SMA youtube channel. That thing rips!

 

[Trav]

Yep 700 RPM but is small and looks bulky, 400 RPM for the Earthquake is faster than many (the IR 107XP has 160 RPM).
Its specs look good and its not Chinese, 4 CFM is low which tells me that if that's correct it probably has a pretty efficient little air motor in it. Its not pushing any instant dislike buttons.

HF seems to imply that Cr-V isOK for impact use...

Wouldn't 160 (or less) rpm be better?? I get it that this is all about speed and money, but at some point if think it would become uncontrollably fast, or else a little torque at really high rpm turns into a knuckle buster!

I've used my HF air ratchet quite a bit with regular sockets. Impact sockets are often too bulky for tight places.

That's because everyone should know you buy the pro and earthquake lines.

The regular ones are as ok as any super cheap gear but if you want decent HF tools you need know what you are buying just dont go grab a random tool off the shelf.

you can find cheap junk anywhere not just HF.

I guess what I'm trying to say is

don't be judgmental.

Otherwise you could say all Ingersoll Rand Tools are junk because Granger carries some POS Chinese one that sucks.

Yes HF has some really really bad tools. I make fun of them myself, but some of their tools are just short of excellent and extremely good value.
Sure spend massive sums on brand name professional tools. I love those too. But for those who don't have the budget.... There are some good alternatives at HF.. That blow the Autozone, AAP, Sears shelf alternatives away as far as value and quality.

Its not the RPM you need to worry about its the reaction that slams the knuckles into the closest piece of iron. The impact ratchets have very little reaction and are painless.
I don't like low RPM ratchets, lots of noise without much work, I'll take 400 RPM any day.

I like the sound of my HF 3/8 ratchet.

 

[HangFire]

All those RPM figures are free-run (no load). You can only approach that speed in use with a very clean light fastener, like running a new nut down new all-thread with light lube on it. Even then, there's no standard for how much the tool slows down under a real load.

My old IR non-impact is only 40-some pounds, and it sure gets my attention when it puts my hand against the car frame, but it doesn't hurt (that much.) I wouldn't add another 10 ft-lbs though without going to impact. I'm thinking about it, but there are higher tool-buying priorities.

They Will be fine.
the chrome sockets will wear the anvil out on the impact

Hogwash. Not everybody knows to pick earthquake and pro lines, and even then, often the "pro" lines are as much advertising as anything. At least at HF they do give Cr-Mo, but still. Knowing to pick Cr-Mo is not intuitive in all cases. Admittedly I had questions about it myself...

https://bobistheoilguy.com/forums/ubbthreads.php/topics/3558920/Cr-V_vs_Cr-Mo_for_impact_acces

HF is advertising Cr-V as appropriate for impact by selling that product and coloring it black (which for the bystander implies "impact socket"), and Ill bet that the average worker there and the average shopper there wouldnt know the difference or reason... So in the end they will buy what's cheaper (that's why most folks are at HF anyway, after all, they even advertise that they sell at "outrageous prices" or something like that in indicating that they are super-low priced).

Either Cr-V is OK for impact, or it isnt. And AFAIK as a rule Cr-V is not appropriate for impact. Therefore it's a shame that HF misleads the public this way.

But this has nothing to do with bad tools. Those Cr-V black "impact" sockets might be wonderful Cr-V sockets, that are unmatched in the tool industry. But are they appropriate for impact use? That's the question. HF does have some really cheap stuff, and it does have some diamonds in the rough. But the issue here is misrepresentation of a product.

And its not clear how great the stuff is regardless:

This isn't so much an impact ratchet as it is a knuckle saver. Its not like the impact action is anything to write hom about. SOP, like any air ratchet, is to use it as a nut runner, then final torque by hand. Let it "impact" too long and it will shear the drive pin to the head. Regular chrome 6 points should suffice.

That being said, I used mid depth 3/8 drive impact sockets for everything. All my 3/8 chrome sockets were retired long before I was.

Edit: Salute to my 20+ year old IR111. No regrets on that purchase.

Cr-V is used in impact sockets, its a little misleading though. I have Hazets that are Cr-v and are 25 yrs old, they are actually Cr Mo V.
You will never get a 100% answer to this question as that would require the company to divulge exactly what the mix is of the steel and that's probably proprietary.

I'm of that mindset to use it as a high-speed nut/bolt removal/install tool. After seeing the torque spec, 70 ft/lbs could indeed bust a knuckle wide open if not kept in check. Considering that alloys generally get torqued to 80 ft/lbs, which is a decent pull on a 24" long torque wrench, 70 ft/lbs could do some damage if a bolt binds on something unexpectedly while the ratchet is powered on.

 

[Superflop]

For general nut running I've fallen to using my astro 1119 with swivel tip and nice light flexzilla whip more than most of my other much larger, heavier, bulkier air ratchets but [censored] it can be a touch loud when it's close to your head

 

[brages]

I have this ratchet. Yes, it is fast. Yes, it will NOT bash your knuckles.

The power of this thing is mild enough that I think you will do fine with chrome sockets.

 

[tig1]

You don't need impact sockets for an air ratchet since an air ratchet isn't impact.

 

[brages]

The one the OP is talking about is an impact air ratchet.
