Thread: Threading bar question

So...I'm looking for a good threading bar. And I came across this web site.
TBG Series Threading Bar
This thing looks great, just what I need. Only problem is I cna't find it for sale anywhere. Any help?
Thanks

We use top notch threading bars at work and I love them,take a look on ebay I have bought a few from there for at home they look very similar to the one your showing.
You can get all different types of inserts.

From the website you linked with the TBG bars, their contact info.

These seem to be similar to the Everede boring/threading tools.

I have the TBG 750 and it works great! I am not sure they sell that model anymore, but the inserts are avaliable forabout $20 a piece. I am not fond of carbide however and never use it any more since I got my HSS indexable tooling. If you do not mind a used one, I would not mind selling you mine.

Thanks for all the info guys. And deervalleygun I sent you an email.

I don't often hear of someone going from carbide to HSS. What is it about carbide that you're "not fond of", deervalleygun?

Me, I don't think I'd get into those $26(!) per edge inserts. For less than that per THREE edges of a lay-down insert, I can get pitch-specific cresting inserts that give me a burr-free, smooth thread, and I can buy one or two at a time. My smallest insert-holding bar gets into a .240" hole, but at those sizes I'm usually tapping.

I'm not clear as to what size threads the OP is making that this tool makes sense. I've gathered a few various Micro 100 solid carbide bars for small I.D. boring and grooving tasks, and I love them because the carbide is so tough and I can resharpen them easily. At $10 to $25 each on Ebay, they've been very affordable. I have some HSS tools, but they collect dust more than they make chips.

The smallest bar I have isn't shown because it's so small and being solid carbide I keep it with the Micro 100's. The smaller of the two shown in this crappy cell phone photo is a 5/8" and gets into .750" bores with the 16IR size inserts. Full array of anvils to adjust for nearly any thread, I don't think I've got more than $250 into those tools thanks to Ebay. The drop-head holder was, for instance, $24 to my door.

Everede sells a bar a lot like the OP's bar, and you can outfit it with either HSS or cabide inserts. The inserts are easily resharpened, but proprietary shape, however. The usual suspects like MSC and Travers sell them.

I got a threading bar from Mesa Tool. The same bar and inserts can also do external threading via the opposite end of the bar.

KC9LJO, I am not sure I have my e-mail set up to work on this site, but it is deervalleygun@hotmail.com

PixMan, I mostly work with aluminum and found that HSS gives me a little better finish. Also, I pay half the price for two more cutting edges with HSS for my AR Warner tooling. I am only a hobby machinist and it just works out better.

Were you aware that there are HSS inserts for the lay-down threading tools?

Valenite used to sell it as their grade "VC922", but they're all discontinued now and I don't know where they got them. Carmex made most of their carbide threading inserts, but I don't see HSS there at all.

I did not know that. I will keep an eye out.

Thanks PixMan

Correction!:

The HSS grade is VC942.
