I have a few screws (flat head) that the flat head slot had worn out, and
since the screw is a finish screw it is recessed deep into the surface so
cutting a new slot with a dremel for example is not practical.

So after a few tries I decided to get a screw extractor. I bought one at
the right size at HD brand name KOBALT.

I used the drill bit and drilled a hole about 1/4" deep. Then I took the
other piece that is called the "plug tab" and put that into the hole and
turned it counterclockwise with a wrench. The plug tab turned but the screw
stays. I then use a hammer and lightly tapped the plug tab deeper into the
hole, turned again and same result.

I thought it's supposed to "grab" the inside surface and turn the screw but
it didn't.

So either I am not using it right, or I did not drill deep enough, or this
is a piece of crap screw extractor and I need to get a good one.

Any idea what I should do?

You didn't say what material the screw is, what the screw is screwed
into, the size of the screw, whether the screw is corroded in place,
etc. The more information, the better the answer.

If the screw is really seized up in there, and the screw is made of
softer metal, you're probably out of luck. If the screw is into metal
try hitting it with some penetrating oil and letting it soak
overnight, then try again.

Drilling deeper? I don't know, how deep did you drill?
