My chuck is ceased in the closed position and I am unable to open it.

Is there any way to open it ?

My chuck was stuck partially open. Could not back the retaining screw all the way out. I had to cut the chuck off with a grinder.

Horrible directions. “Toward you” doesn’t make sense. Establish a frame of reference (facing the chuck) and state clockwise and counter-clockwise. That does make sense.

My drill has a hex screw holding the chuck on… not a Phillips screw shown in the videos. I cannot get the 7/64 Allen wrench to loosen the “reverse thread” screw. Afraid I will break the Allen wrench.

I have removed the set screw from the chuck, installed a large Allen key tightened the Chuck, smacked it with a rubber mallet as hard as possible, the chuckwill not come free, just ratchets. What is the next step?
