No hole-saw kit is complete without a plug remover: Might find them at Home Depot or the like. They work well for rough cut, but the finer the teeth, the tighter its going to be stuck in there. Reaming a few times before you punch through helps.

Where Phillips heads were designed to cause the driver to cam out, to prevent overtightening, Torx heads were designed to prevent cam-out. These screws are also ...
Some tips Use the correct sized bit for the screw head. This really makes a huge difference. Some bits are much more accurately made than others. Buy a new one. Lubricate the screw. I have a tin of automotive grease I use for this but I've read you should use petroleum jelly (e.g. Vaseline). This quick and easy to do, just dip the srew before inserting. ...
