Collet Adjustment
There are two collets per spindle, making 46 collets per head. The collet on the bottom of the spindle
is used to lock the drill bit into the spindle assembly.
The upper collet is used to hold the entire assembly to the head.
To get the best results the upper shaft collar should pushed as close to the snap ring as possible, and
then tightened.
