i was going to order maybe 3-5 of these... what do you guys think. Could be a great substitute for the tormach tooling collet holders... i have a tts er20 collet holder and was wishing i had more collet holders, but at $92 a pop its just not pratical.

The difference is the collar is most likely not ground like the TTS is, but based on this picture

it looks like the differences would be negligable.

Just a heads up to anybody.

oops... there isn't a collar duh on the cheap chinese ones... so the z surface would change depending on how tight you tighten the drawbar. sketch, ill just stick to TTS.

cheers

You can add the collar to any 3/4 shank tool, prolly need to cut the length down to match your other TTS tooling.

That seems like a pretty good deal and as Hoss said you can add the ring. I think the rings are like $19.00 or you can make your own. Shars has some of these holders and from my past experience with Shars they are probably in stock and you would have it pretty soon. I just received my first coaxial indicator from them and I got it in two days. I have always used my Zero set test indicator holder and a DTI but after seeing a coax in a video on Glacern's website in action I had to have one. This is a real nice unit and came in a quality box. I am anxious to use it...

I have been wanting some of the TTS style collet holders and was thinking about getting some of these and converting them. I already have bought a 3/4 inch shaft for my boring head from shars and cut it down to be a tts unit. I am trying to find a good deal on the collet holders so I can equip my machine the way I want....

I have had reall good success with these holders and love the Z repeatability of them. I am just starting to actually use that repeatability with the software and it sure is nice.... Good luck and peace

You can get the rings directly from Tormach for under $9. I was thinking of getting a bunch to use with the ER25 collet chucks from Maritool which sell for under $50.
