5c Collet Size ???

[john mullen]

I have need of a 5c collet that will hold a 1.250 dia shaft in my spin index. Does such a size even exist.

1.0625" is the biggest 5C goes

Hardinge makes a 1-1/4" extended nose 5C collet, but its $150.

It may vary from brand to brand of collets, but I think most brands of 5C collets will not pass the part all the way thru over 1" diameter.

I stand corrected. Yes step collets are available up to 6" size. Also collets for clamping the ID of parts up to at least two inch.
SPENDY stuff though.


If you have a lathe you can make a custom collet out of one of these

Turn it to hold whatever you need.

I am going to need a 7/16 5c collet tomorrow, If I remember, I will see what my largest one is.

Buy a 5C adapted 4" 3 jaw chuck. Check them out on Ebay. http://www.ebay.com/itm/3-3-JAW-5C-...565?pt=LH_DefaultDomain_0&hash=item5b09c7afdd

If your shaft needs to go all the way through the collet your out of luck. If speed is not an issue, "holescreek"s suggestion 3 jaw chuck, seems like reasonable price and good suggestion. Other that that an emergency collet machined to size, carefully, would probably be most accurate, and depending on your releasing mechanism, the fastest.

hardinge makes a step chuck for 1.25 but it doesn't have much depth the biggest 5c collet I have seen is 1 1/8" that has a through hole hope this helped.

Thanks guys... I think I will go with the emergence collet and turn it in my lathe.. I think it will have less run out than a 3 jaw... I saw a emergence collet on the net but didn't know that it could be custom fit in a lathe... This I can do...
