Snap on make or sell excellent taps.
I bought a bunch of them recently including that size.
They are US made, but they may be made by Irwin and rebranded Snap on.
So warranty them though
I've used them many times with great results

A tap is used to cut new threads, a thread chaser is used to clean the threads.

Just to be curious, what would be the problem?

A tap cuts metal off, potentially making the lug nut weaker. A chaser kind of smooshes the metal back into shape without quite so much cutting.

Look at your own original post
Sounds like you just want to clean/straighten the threads instead of making new ones possibly ruining the lug nuts in the process with a cutting tap.
How much does it cost for a few new lug nuts vs the "usa quality" made tool ?

Look at craftsman 48 piece re threading kit it's the same as snap on but a lot cheaper and will include die and tap rethreaders all us made too

Woodstockva has a great review on this set aswell
Not trying to be obtuse, but I'm really not following the difference. The "thread" is already in place, and has already been sized...wouldn't a chaser or tap simply follow the thread as its already been cut? How would a tap cut a new thread? I could understand if the tap was oversized, or out of spec, but wouldn't a 12x1.5 tap leave a thread that was already 12x1.5 the same dimensions?

A die may pull of a little more meat off, but honestly, if a die is suppose to cut threads to correct size, I have a hard time believing it would under cut existing threads.. The big plus to buying SO, lifetime warranty. Craftsman doesn't warranty cutting tools..

Jason, I've chased/cleaned up over a hundred lug nuts and also chased an equal number of wheel studs in my lifetime using standard taps and dies. Never had a problem with any of them even using and impact gun. If the nut or stud is to far gone I'll put a new one, but just cleaning them up a regular tap/die has worked flawlessly.
For something like an exhaust or bumper mount chasing a thread with a tap is no big deal, but with something like lug nuts that could turn into a serious safety issue if not done correctly, a tap is not the tool to use.
For instance, threads are graded by class, which is the size tolerance the manufacturer is required to hold. And for safety and high stress parts like lug nuts the tolerance is very tight. If you get the wrong tap with a larger tolerance you will open up the threads creating weaker threads on the lug nut that may strip out during high stress situations. In general the taps you will find and want to actually pay for are class 1B which has the largest tolerance range, where a class 3B thread is most likely what has been called out on your lug nuts and studs, and who knows where the thread tolerance range is located in relationship to zero.
If I were you I would either get new lug nuts or a thread chaser.

Depending on the threads original fit spec i usually find using a chaser gives a tighter fit then re cutting with a tap. I have worked at places ware both a tap or re threader was the norm. If you don't want to buy a re threader set you can take a bolt and cut a few slits into the sides (this is great if your trying to clean deep head bolt threads).
I bought the S/O re threading set years ago its one of the best tool purchases i have made. The C-man or Kalstar (oem) would be just as useful IMO

With all due respect, a non-usa tap could also be perfectly capable of chasing threads.
From this set of 3, the plug tap may be best if the lugs nuts are acorn type so as to get to the bottom of the hole. Otherwise the taper is fine.

I have the craftsman restorer kit mentioned above, it's proven very useful on many occasions.
I recently damaged the threads on a cv joint during a wheel bearing replacement, fortunately the new wheel bearing came with a new bolt. I tapered the end of the old bolt with a grinder and using a thin cutoff wheel in a Dremel I cut slots as mentioned above.
Saved my donkey and a C note to boot.
I'm sure there are several opinions on how you should cut the slots for best effect, mine where simply straight and parallel to the length of the bolt.

This.
Jason -
The difference is Taps have sharp threads for cutting and thread chasers have rolled threads with slits to clean up damaged threads.
When I was younger I used taps for everything.But then I figured out that existing threads are not the same after running a tap thru them.
When you drill a hole and want threads for a new bolt use a TAP
When you have lugnuts that have a small burr on them use a Thread Chaser.
If you have specific bolt or nut that have rust,corrosion like when you remove a steel bolt out of an aluminum part use a Thread Chaser/Die and some oil

I bought the Cman thread restore kit for $50, last month. It works great and I have used it on my vw air cooled engine that I pulled out of my dune buggy.
In the past, I have had a tap or die actually remove metal from a set of threads. As said above, some threads have tighter tolerances than the taps I have. My tap set is the biggest one that sears had on their web site, about 10 years ago. I think it was something like $269 and it is labeled Cman. The thread chasers don't remove metal. The nut fits tighter than if I had used a tap or die.
Don't waste this great excuse to buy another tool.

I also only used taps and dies for cleaning up threads. Until I found thread chasers. They're just a better tool for the job. Only once did I ruin a bolt with a die - the damage at the end of the bolt actually guided the die so is cut new threads on the peaks of the old ones. By the time I realized it, the bolt was beyond saving. Whether I would have saved the bolt with the thread chasers, had I known they existed, I don't know.
