Tool question (collet holder)

[Miniliteman]

Does anyone know what the make and type this (I think the english word is) SK-3 colletholder is?

Is that for a mini drill ? Hard to tell the size. If so the ones I have are called drill bit collets. They aren’t exactly the same as this but they come in different shapes depending on the chuck and size. Hopefully that might help in some way

It's a tool holder for a milling machine / lathe.

they sell sets on ebay etc, you need the tool head that holds them with a fitting to suit your machine . the ER number relates to the collet set size

That isn't any kind of ER collet that I've seen! Looks more like a R8 type but nose is odd?
