A slightly larger nug-splitter?

[littletoes]

Working on old equipment, you sometimes need something like this;

But it doesn't quite fit a 3/4" nut....anyone make a slightly larger version??? Wouldn't want to spend the money for a hydro version...that would break the bank!

Hammer and a good sharp chisel?

A thin cut off wheel on a 4 1/2" angle grinder?

Do you have a lot of nugs to split?

 

[airbatica]

Can you not use an air hammer with a chisel attachment?

[Jagmandave]

Yes, but......$108.00 ?????

 

[hammergodthor]

I was going to suggest a mini-ductor:

yes only $108.- !!!

 

[Outlawmws]

Considering the smaller SO is over $80, $108 doesn't seem that far out..

Ya know, I've used them to put large bearings on, but never seen one that was intended to be used on frozen fasteners...interesting idea!

 

[bottleneck]

$108 is not much for a mini-ductor.

Cooper tools makes a larger and far more robust nut splitter than that of Snap-On. Theirs is honestly the best I've ever used.

 

[jannejan]

I had never seen a nug-splitter either. never had to use one. what are the main uses of it?

Um, yes it does?

Nut Splitter

Stock#: NC52 $82.95
Description:
For splitting nuts up to 3/4" across the flats. Bar acts as a handle to hold tool securely.

And mine fits with some clearance to spare. Sure you are on 3/4" across the flats?

 

[Outlawmws]

And a KD-715 (if still available...) will do 7/8 (sorry no pics; Camera Bats died and are being recharged...)

 

[Murphy4570]

I never really understood the point of a nut splitter. I always use a cutting torch, a little heat goes a long way for frozen fasteners.

 

[littletoes]

in some areas, where you may have to worry about fire suppression systems, you just can't use a torch, and yes I do understand the use!

OutlawMWS--I'll check those out....these might have been extra-heavy nuts, which are bigger OD.

 

[Outlawmws]

Here is both the SO and KD.

I believe the K-D can take the SO cutter and anvil, which is nice to know if you happen to have munged either.

Personally I like the SO and how it is used better, but the K-D will go 1/8" bigger...

 

[littletoes]

MWS---Are you sure that's a 3/4" nut? I was just in my garage, checking my SO out, and don't think there is any way it will fit over a nut that big....doggone, now I got to find a 3/4" nut!

 

[franzdom]

OP means 3/4" threads not tool size.

Yes that's a 3/4" nut, across the flats.

It's possible...

The one time I thought a nutspilter would be the perfect tool, I had to remove four nuts that held on a plastic floor pan. The nuts threaded onto carriage bolts and all spun. I didn't want to heat them and wreck the plastic. I left work, bought one from grainger's because it was the only other then hf that had one. Came back to the shop tried it, would not work on a one out of the four. Ended up spliting with an air hammer. For me, the nutspilter is a useless tool, in 15 years wrenching I never need one other then that one time.

 

[littletoes]

They save me a ton of work when replacing the tubes on certain boilers. After repeated heatings, the retaining nuts sometimes get extremely frozen on there, and either you brake the studs off, then have to break out the welder, or you cut them off the best way you can.

Sometimes you can't use a torch, and a skinny wheel will cut up the boiler too. Neither (when including set-up time), will work as fast as a nut splitter.

Do splitters like these damage threads at all?

 

[littletoes]

Here's mine next to a 3/4" grade 5 nut, and a couple of 5/8" nuts.
I don't think its big enough to do either.

Nope, if done right, won't hurt the threads at all! Great tool when needed!

 

[Outlawmws]

I never have and I've done dozens, probably hundreds over the years. (I've had the SO splitter for about 35 years...)

Yep you were talking thread size and I was talking across the flats...

Not sure you can get one that big in a manual splitter, you may need to go hyd, or try an air chisel, or fabricate one. (if you try that, use a fine thread driver bolt...)

Ya know, I've used them to put large bearings on, but never seen one that was intended to be used on frozen fasteners...interesting idea!

it was originally made for nuts. the bearing rope came later. it's cheaper to buy the kit of 6 or 7 "tips" (in varying sizes for varying sizes of bolts). get the kit with the extra long leads - great for reaching into deep areas...

I got a mini-ductor 2 a couple months ago and love the hell out of it. i call it my "little nut burner" and pre-heat everything underneath that even looks like it might be a problem. haven't touched my kroil since I started doing that.

Funny, all this talk and I had just mentioned to the wife I was going to replace the receiver hitch on our small trailer.

As my Son was working on his car, I was going to unbolt the hitch, and laughed-the second nut was frozen on there....what timing.
Had no problem getting it off there!
