3AM Collets that are Surplus to My Needs
[All sold]
Six Ames-type 3AM collets
These six collets became surplus when I bought a group of Ames-style 3AM collets on eBay recently.  It is only fortuitous that the left-overs happen to be graded in size from 3/16ths inch to 5/8ths inch. 

The largest of my other Ames 3AM collets has a 3/4 inch bore.

The outer surfaces of all six collets are free of pitting; and their threads and keyways are undamaged.

I took the photographs of the collet faces before cleaning the very dirty bores with a paper towel. See the bottom row for a better look at those newly wiped bores.

The 3/16ths inch collet appears to have been partially bored out to a larger size - there's a step clearly visible inside the bore.

The other five collets have clean bores.

Every one of these collets fits the spindle bore and drawbar threads of my Ames bench lathe.
