I bought the Grizzly 18v 1/2" drill, G8597. Problem is the chuck loosens
when backing out screws in reverse and drops the bit. Griz Tech sent me a
new one within 2 days, great services. Now having a problem getting the old
one off. Took the screw out in the chuck but for the life of me I can't
break the threads loose to get it off.

Keyed chucks are easily removed by tapping the key, done it many times. How
the heck do I get the keyless off? Tried everything I can think of so the
solution must be too simple for my old mind..??

Help, Guys.
