Hi Tony Sounds like Myford collets. There will be a groove around the wide end and that snaps into a closing ring that screws onto the Myford spindle nose and draws the collet into the taper of the spindle. The tube is used to compress the collet to make it easy to insert it into the closing ring. The mushroom ended bit pushes the collet out of the tube once it has been inserted into the closing ring.
