3H Lathe Collets for CNC Milling

Description

3H Lathe Collets for CNC Milling - 17 pieces with custom wooden case
I am not a tool and die person, these belonged to a family member. They are all in good shape from what I can tell and come with a wooden case that they all fit into, except for one piece, not sure why, but the hole in the middle of the case is bigger than all of the others and if you try to put one of the collets in that particular hole, it will fall down inside the case and it’s not that much fun getting it back out again - trust me on that one, haha. It’s quite possible that the set had a piece that did fit in there at one point, but I just don’t know.
The sizes of the collets are as follows:
1/8, 3/16, 1/4, 5/16, 2 - 3/8 pieces, 7/16, 2 - 1/2 pieces, 9/16, 2 - 5/8 pieces, 11/16, 13/16, 2 - 3/4 pieces, 7/8.
