drill chuck removal

[spkrman15]

Hey folks,

I have a 3/8 electric black and Decker drill. There is no screw inside of the chuck. The chuck takes a 7/32 allen key in the center. Is this pressed on? Is the shaft all one piece? I have removed it from the drill and i can see no sign of a taper. Any suggestions

The chuck should unscrew. Put a rod or the chuck key in one of the holes and give it a tap to loosen.

It should unscrew if it is a hand drill. If I remember correctly, the allen screw in the chuck is right hand thread but the chuck is left hand thread on it's arbor. Take out the screw, then chuck your allen wrench in the jaws and give it a tap with a hammer. Remember, left hand on the chuck. It should come right off.

Left handed thread on the screw. Right handed on the chuck. Hmm, allen head screw, good idea.

Also you could take that same allen wrench an tighten it up with the short end in the chuck. (After you get the center screw out) Sometimes they take a little whack to break them loose.

I just removed a broken keyless chuck from my Milwaukee cordless. The internal screw was a left hand thread and the chuck itself was a normal right hand thread. Mine had a torex screw head and I broke the ends off 4 high quality screwdrivers and allen style wrenches before having to cut the front of the chuck off with an abrasive cut off wheel and grind a relief slot in the screw. Once the screw was removed the chuck basically unscrewed by hand. I never had something screwed together so tight in the many years of messing with things. The machinist here at work said that everything must of had a perfect alignment to make it lock together so tight. He said something like that happened to him once before in about 35 years in the trade.
