Drill Chuck Removal
Removing Threaded-on Drill ChucksMost handheld
drills and drivers have threaded-on chucks, although, that's not always
the case. But you can be certain that all keyless chucks are
threaded-on chucks. Again, it's best to check the owner's manual if
there's any doubt.Threaded-on chucks are tightly screwed to the drill's spindle and are held in place with a screw deep inside the jaws of the chuck. This screw helps hold the chuck on the spindle during operation, preventing it from spinning off.The first step for removing a threaded-on chuck is removing that screw in the jaws, which might need an Allen key, torx driver, or flat-head screwdriver, depending on the drill model.1. Remove the chuck screwThe most important thing to remember for this step is that chuck screws arereverse-thread and need to be turned clockwise. This reverse threading counteracts the torque of the drill, keeping the chuck tightly connected.Because
those chucks are threaded on so tightly, they won't just spin off the
spindle once the chuck screw is removed. Chucks are often torqued on so
well that a drill may operate normally if a chuck screw falls out
(although this is not recommended).
