1040 Collet Set

Collet set, collet closer with sizes (1/8, 5/32, 3/16, 7/32, 1/4, 9/32, 5/16 and one blank)

The collet is used to hold small diameter workpieces and small diameter milling cutters.
The advantages of collets are:

-   material can be loaded quickly
-   collets are very accurate
-   maximum spindle speeds can be used

Note: (A collet turning at 5000 rpm is a lot safer than a chuck at 5000 rpm)

Collets normally accept material that is .001 inches over the collet size and .004 inches under the collet size. Bar stock is usually within this tolerance.
