If you are turning material 4″ or smaller you should take a look at Royal’s Quick-Grip series.  These are extremely accurate and can be customized to accept hex or other shapes.  In a production environment where you may have to change sizes often these could save you time and improve your setup accuracy.  Also, by counter-boring the collet, you may be able to turn 5″ material in a 4″ chuck.  Naturally, there are some part size considerations.  However, in many cases it can solve a major problem and let you use existing equipment more effectively.
