I MAY or may not have caught this in time, but I ordere a few er32 straigh shank holders yesterday, and ordered them with what seems to be the standard 1" shank - Ooops - R8 "standard" collets go to 3/4" - but "step" collets ARE available

I have tried to change my order, but no word back from the vendor, and shipping back isn't happening (Hong Kong)

Anyone have a picture of the business end of a 1" R8 collet, and how DEEP (or not deep) the 1" section is, just in case?
 
The 1 inch diamter portion would not be able to exceed around 2/3 inch unless they extended the nose quite a bit. The straight portion of the R8 holder is less than 1 inch in diameter.

Once extended, I'm not sure how rigid / tight it would be.

Bout what I figured - sigh

I hope I caught it in time before they were shipped - if not, I'll be selling 5 ER32 straigh shank tools - cheap, and ordering a bunch of 3/4" shank. Made worse mistakes in my life, at least this is one that throwing money at can solve
 
It shouldn't take long to turn those shanks from 1.000" to .750". I would doubt that they're very hard.

But you'll need a lathe :nana:
 
Plibbit - a lathe I have, and a surface grinder too - I guess I can try the 1st one - but man, I was thinking the kind of runout numbers you ideally want - better to sell them at say 1/2 what they cost me, and buy replacements. If I can get 1/2 price, the 'mistake' would be double digits, which is in the category of "ah, that was dumb"
 
Good news - caught the order before it shipped, and he confirmed he's shipping 3/4" shank tooling - woohoo - so basically I'll be "home" making a TTS tool system - in fact, I MIGHT buy some stuff from them too. I just which that Tormach sold an ER32 collet set vs ER20. Yes, I know they want to limit folks to 1/2" but...
 
I think we all know what an ER32 collet looks like, ditto a ER32 collet holder. Most of everything is still in their boxes - I unboxed 1 collet, one holder, and one wrench, and inspected the rest of the holder through their clear bags

It LOOKS like if I want the holders fully sunk in the R8 collets, I'll have to cut them down a bit. The GOOD news on that is that I have a cutoff disk in my surface grinder, and it's what the grinder was being used for when it was last used
