Follow the professional repair tips below for to remove a stuck chuck screw.
Tip #1- Heat the arbor shaft.
Use a blowtorch on the arbor shaft to loosen up the loctite on the chuck screw. This is the best way to loosen the screw in most cases.
Really tough chuck screws may require more than one heating.
Tip #2- Use a wrench for leverage.
If the screwdriver you're using to turn the chuck screw has a square shaft, you can attach a small wrench to it for some extra leverage.
Tip #3- Strike the chuck screw with a screwdriver and hammer.
Carefully position your screwdriver on the chuck screw and gently strike its end with a hammer to loosen the screw's loctite bond.
This should be considered a last-resort method since it risks destroying the chuck if done incorrectly.
