    Collets on Faro's and other quick change handpieces wear out. 
    Simple as that. It's usual, and depending on how much and how you use
    it will determine in part, how long a given collet lasts.  A new
    handpiece doesn't get you a more durable collet, but it does get you
    all the rest of the parts, bearings change levers, springs, etc.  Buy
    the new handpiece when the old one is getting too sloppy in areas
    Other than the collet. 

    Your run on foot pedal might well be contributing to handpiece wear,
    if your not letting the handpiece stop before opening the quick
    change lever.  The faros do not but ball bearings in the change lever
    mechanism, so if the shaft is still turning, then the lever acts as a
    break, and that will wear down that little cam inside that's doing
    the changing.  And if the collet is still turning when you pull out
    or insert a bur, then the bur is increasing wear on the collet. 

    And no, you're not the only one to whome this occurs. 

Peter
