Welcome. My name is ***** ***** would be glad to assist.

There are a variety of models on the market past and present.

Which Model is the drill?

When you turn the chuck, normally while holding the base, the entire head removes, is that what is happening?

Let me know and we can continue,

Ok, thanks.

The H1 is only a Type, there should have been a model number prior to the H1.

Normally there is a ring behind the chuck and holding the ring while turning the chuck, opens the chuck for bit changes.

So, is yours built this way?

Where is the chuck dismantling form the drill?

Maybe a picture of yours to show before and after for review?

Pictures can be posted here with the paper clip symbol on the chat tool bar.

Ok, thanks so much.

Yea, that model has the head threaded onto the main shaft.

Putting the forward reverse slide to the center position and then turning the chuck mechanism is supposed to open the chuck.

It looks like the head itself is not tightened enough to prevent it from un-threading when opening the chuck or else the bit is really stuck in the chuck.

The screw down the center that assists to hold the head in place has come loose.

You will have to place a small cloth around the black ring to keep from scaring it, and hold the black area on the chuck with a pair pliers and then turn the chuck .

Normally they have some loctite to keep the head fastening screw threaded without movement, but for some reason yours has worked lose.

You can tighten it back up the same way as above, turning the chuck with pliers.

You have to be careful not to scar the ring. which is tricky but can be done.

You also, may be able to put a cloth on the chuck, then rap it a little with a handle of a tool and dislodge the chuck, similar to a new jar with a stuck lid on pickles, tapping around the chuck.

It definitely is not normal, but the screw threads gave way too soon and were not treated with a loctite lubricant that helps hold it in place.

The screw may also be helping to hold the chuck in the locked position, hard to say since we can see internally.

See if that will release the bit and then get the head threaded and tight and in place.
