which may require you to use
new hollow drill bits.

while in the down position.
Push up on the Chuck and rotate
slowly while holding the Spindle

The Chuck adjustment is designed for a 1/4” total move-
ment up and down. Once you have sharpened the drill bit
down more than a 1/4” from its original length you must
replace it. Any drill bits that are longer than approx 2-1/4”
or shorter than approx 2” may cause Chuck adjustment
problems.
