   Several machine collets (top and centre) and a dismantled pin chuck (below). Generally, a collet chuck, [3] considered as a unit, consists of a tapered receiving sleeve (sometimes integral with the machine spindle), the collet proper (usually made of spring steel) which is inserted into the receiving sleeve, and (often) a cap that screws over the collet, clamping it via another taper.

The collets or tool holders are placed directly into the spindle and the drawbar is tightened into the top of the collet or tool holder from above the spindle.

   The Jacobs Rubber-Flex brand is a name that most machinists would recognize for this type of collet chuck system. Regardless of the collet design, the operating principle is the same: squeeze the collet radially against the tool or workpiece to be held, resulting in high static friction.

To use a 1/2" shank end mill, you install the 1/2" collet, insert the end mill in the collet, and tighten the draw bar to retain the end mill.

The piece was struck by the tens of millions, at all three mints (Philadelphia, Denver and San Francisco), through the remainder of the ...
