Rod/shaft marred by collet
1. Check collet orientation . If the collet has an orientation indicator dot (see photo), the
indicator dot must always face toward the top of the holder . Collets without the indicator
dot are not dependent on orientation .
–
If the collet is upside down, remove the locking collet bolt from the holder and gently
tap the holder on a hard surface to remove the collet .
–
Reinstall the collet with the orientation indicator dot facing toward the top of the
holder, and then reinstall the locking collet bolt .
2. Check the collet for wear .
– A worn collet will not distribute pressure evenly on the rod/shaft and may cause
damage .
– If the collet is worn, the entire holder must be replaced immediately . Collets are
matched to a body assembly during manufacturing and cannot be replaced separately .
