That is neat. Looks like it might be tempting to get heavy handed with it.

Keep the RPM down and the feed rate up, add oil and it could last for a long time.

This is one of those tools that's like wow that was a simple concept why didn't I think of that.

Ive never pledged anything to a kickstarter before, but that seems pretty damn useful to not pick atleast one up.

Not to be contrarian, but I fix threads like that with files and/or a semi-soft deburring wheel on a bench grinder all the time (when they're too bad to just run a die over). It's almost always the outermost part of the threads (the peak of the triangular thread cross section) that is folded over/problematic. A buffer allows you to reduce the bolt diameter slightly, leaving something that looks more like a squared off/acme thread that will _still_ engage with the nut. Also, a lot of times the cross threaded part is not at the end of the bolt.

Maybe there's a use for this for fast field repair on something that cross threads a lot of bolts? Otherwise, this tool is way too aggressive for me. Seriously, if I saw someone do what they show in the example video to a cross threaded bolt on one of my machines I would kick them.

I contributed about 30% because I think this might be useful, and 70% because this is Americans designing tools to be manufactured and used here, which is a cause I want to support.

I think their target market is mostly construction and auto repair- people who are VERY time sensitive, and who often work on fasteners that are difficult or impossible to remove for a thread repair. I would agree that this tool has less of a place in a production or machine shop environment- but for auto and especially construction, I think it's right on.

I saw this last week and sprung for one. Yes there are better ways but for quick automotive fixes and construction stuff it is a great idea. Just to fix the damaged end on carriage bolts that were pounded through something will make it worth the cost.

Plus the ship time is really quick for a kickstarter

I guess. But in automotive applications, you can rarely afford to have a bolt shortened that much.

For a bolt in my hand, two seconds on a belt grinder and a twist of the fingers is at least as good. For a bolt I cannot pick up, I'll stick with a file.

And this still will only remove the last thread from a bolt. A triangle file will fix your bolt as far back from the end as you need.

Perhaps if I was making hundreds of cutoffs of allthread for a job, and I needed a clean deburred end on them all it would be a time saver, but I wouldn't consider paying more than I'd pay for a comparably sized countersink. At these prices, it'd better come with an indexable carbide cutting edge.

"The UNIBURR simplifies the repair process, potentially fictionalizing repair time,"

What the hell does that mean?

Doesn't that happen already?

There are construction jobs that require exactly that. Fixing every one with a hand file *****.

And a high quality coated countersink that will actually last in a machine shop environment (not one you can get at home depot...) will cost anywhere from $30 to $60. So they're not out of range on pricing either.

So what is the verdict on the UNIBURR tool.
This thread is over a year old so there should be some valuable information on the viability of this tool.
Lets hear it GJ.

I didn't buy one :dunno: if I remembered about it, I probably would have for the kickstarter price of $30 or whatever it was, but just looking at their site, the nice one is $65 and that is more than its worth to me. I have enough small files, (you can never have enough files) to fix most buggered threads and if its bad enough that I cant, time for a new bolt

I just ordered one from Amazon. I should have it Saturday.
I will post back once I try it.

Got the Uniburr today and tried it out on a wheel stud that someone had mangled the first couple of threads. This tool made quick work of chamfering the stud allowing the nut to thread on with no problem. It is not a tool that I would use often but when you need it, it will pay for itself in short order.
