I have a kreg pocket hole jig and bit. I set the deph collar as they
specify. However, the tip of the drill bit does not go all the way
through. In other words, the screw must go through some wood before it
will contact the joining piece. Is this normal, or should I tweak the
depth collar setting so that the hole does go all the way through?

No. If you set the collar for the drill to penetrate deeper, you will
also increase the depth of the counterbore, and there's a good chance
that the screw will blow through the undrilled stock and bugger your
I have mine set so that the tip of the bit just makes a bump on
the exit side. I then remove this with my fingernail and I am done.
When I don't do this, sometimes the screw will have enough meat
on the pocket hole piece to grab and push away from the mating
surface, before it starts to penetrate. This can lead to slight
misalignment problems that I would just as soon not have to sand
out. Even when clamped, I have had the two pieces move slightly
enough, that due to the angle, causes a misalignment.
I have never had problems with blowout. The only problems I have
had are cracking of the piece being penetrated by the screw when
it is too close to the end of the piece, usually on harder woods.
