Confirm drill bit position radiographically. Be sure the drill sleeve is pressed
firmly to the cortex, and read locking
bolt length from the calibrated drill bit
at the back of the drill sleeve.
Note:
There is no need to calculate bolt length because the calibrated drill hit provides a direct
measurement. However, since drill bit position directly represents locking bolt position in
hone, the locking bolt will be too long if the drill bit is over inserted, or if the drill sleeve is not
pressed down to the cortex.
