Does this 1/64” 5C Collet Look Right?

[silence dogood]

Good excuse to buy a watchmakers lathe. That way your collets can go down to 0.3mm.

The 1/64" collet looks OK but the collet to the right of it appears to be mismarked. It looks a lot closer to a 1/8". The one on the left doesn't look right either but it may just be the lighting.

I would not have ordered one that small except the trays that I ordered had that size marked. I was just being a completionist.

"Completionist". I love the new word. I struggle to be successful at it.
It's a special, subtle sort of full options, "have the whole set" kind of OCD!

I now just say "Monk".

I'd say it is missing a hole. Compared to the 1/32" right beside it, the hole should be 1/2 as large.

I'd say it's an emergency collet that can be sized as needed.

I also think that it is an emergency collet that they marked 1/64”. I don’t know if you can tell from the photo, but the area around the center has a different surface finish which may be interpreted as a non-hardened area that one can drill into.

The Shars collets were $6.93 each + shipping. I will stop before I post something bad about Chinese products, although I will note that the 1/64” collet is marked Shars, and the 1/32” one has no marking. All 118 of the Crawford collets have consistent markings.

The emergency collets that I have seen have three holes for pins on the slots so the collet can be securely tightened for machining without closing the slots.

Crud. 1/16" is my smallest! And I'm out of holes to.put them in :-(

Must resist!

You are correct. Not an emergency collet.
