Would like to buy a threading tool

I am looking to buying an "Indexing Threading Tool". I am looking at buying THIS ONE to be exact.

I am wanting to cut 5/8" UNF and M14 threads so theoretically I will be needing two different threading tips, which is fine. I will not be using any of my many HSS tools for this job.

Does anyone have any experience of this tool? Or any similar tools.

Thanks in advance,
graham.

I have the exact tool and I bought 55 degree and 60 degree tips for imperial and metric threads. Had complete success, doing an M12 x 1.25 thread in the morning on a gear lever I have made for a TVR. Bit nervous as it is stainless bar and quite tough to cut. Gentle cuts required I think.

I haven't used the Glanze tools, but I do use professional (can't remember which ones) indexible insert tooling for screwcutting. But insert threading tooling does like to be run fast, or the thread tends to tear, especially in materials like low carbon steel. I get round this by using an Ainjest high speed threading unit, which allows me to screwcut up to about 1000rpm, but drop out automatically with a repeatable accuracy of a few thou. Cuts are normally put on by a straight plunge, so for the coarser threads in particular you will need a fairly rigid lathe with plenty of power.

Regards,

Andrew

Graham,

I have a similar tool and it's cut much neater threads than I managed before using home ground HSS.

Will you need 2 different tips? Both threads are 60 degrees and if the tip is deep enough for M14 it should be fine for 5/8 UNF

Thank you very much for all that guys.

I understand your thoughts regarding the high speed Andrew but two things spring to mind, firstly - I am always wary of any product that you cannot find a published price.
Secondly, I really don't want to spend a fortune as it is not a massive job and I would like to see some small return. Going off the assumption that "if you have to ask the price you can't afford it" I would dismiss the idea out of hand. I quite simply cannot see any valid reason why a price cannot be published. Puts me right off.

I am going to order the tool and see how I get on. I will be ordering 60 degree tips and see what the fit is like. Then I will report back.

Hi Graham

Price here.

**LINK**

About £30.

I must admit I'm flummoxed; I can't see the connection between what I wrote and unpublished prices? I bought my external holder from the local tool supplier, and the internal one came from Cutwel, who most definitely publish their prices.

I have several Glanze boring bars and they are fine, although the inserts themselves were of poor quality. I'll be interested to see how things progress.

Andrew

It is of course the Ainjest high speed threading unit I am referring to. I do know the price of the Glanze tooling.

Ah, sorry Graham. I did think your comment a bit odd, just didn't make the connection with the high speed threading unit.

Gary

Just looking at the tool shown, I would have thought that the tool should be on the side nearest to the chuck. A tool holder for a tip like that is not too hard to make, maybe something like this. Ian S C

No worries Gary, it did make me smile though so worthwhile!

Hi Ian, yes, it should be straightforward enough but I have to balance "creativity" with "productivity" and it just isn't easy

graham.

Graham,

Ian is spot on regarding the tool unless of course you are intending to use the tool upside down and run your lathe in reverse [take care if its a screw on chuck] and cut outwards from an undercut in which case you could use a fairly high speed because you have unlimited run out

Another point are you intending to use full form or partial form inserts, if you use partial form then you need to truncate the thread crest, for 5/8 UNF this .006" / .008"

As far as speed is concerned I would not worry too much I have cut 1000's of threads and mostly at under 100rpm and never a problem with finish or otherwise. Yes I know the cutting speed for carbide is much higher but so it is for HSS but you have to be practical and a CNC machine is capable of stopping and retracting the tool in a fraction of a second most of us humans are not and if screwing up to a shoulder or undercut you have to be able to stop your tool before a crash occurs.

Andrew, is that the actual gold coloured inserts that come with the tools or the black coloured ones supplied by a well-known Glanze-assosciated supplier as replacement tips for the Glanze tools? ... just before I go buy some!

Graham

I also have a couple of Glanze boring bars and like Andrew says, they are absolutely fine. I've been using them on aluminium a lot recently with inserts specifically for that application and they do seem to leave a better finish as claimed by the supplier.

Cheers

Ian/John if you look at the charts on the first link the tool holders are available both left and right hand, they only list the right hand on their web sales page which puts the tip where we would most likely want it.

Well I have ordered one anyway so it should be here Tues/Weds.

I set up a piece of bar in the four jaw yesterday and had it centred pretty quickly, then using the other Glanze turning tool I had it down to .5003 thou in no time.

Bearing in mind that this was the first time I had used this whole combination I was extremely pleased with myself. For someone who is on the tools day in, day out this really is just something you do. For someone who hasn't done this in twenty years it was a small achievement with major satisfaction value
