We know that there is a north and south pole, and if the magnet is broken in half, it forms 2 new poles. But what will the force in the center be?
So yes, we didn't just tear the radio apart for the heck of it.

It will simply be a donught magnet (which it already was, you just didnt know it). Normally, when we are misinformed that all magnets are bar magnets, we precieve the magnetic field as a 2-D series of lines going from one pole to the other. However, this field also goes linearly through the magnet itself. Realize that for the magnet you have (and all magents) that this a 3-D field that not only goes from one pole to the other outside the magnet, but also THROUGH the magnet. When you remove the center of this magnet, this field will still be going through that void in a similar manner. If you manage to hollow it out, try pushing another magnet through the empty space to illustrate what happens.
And, the drill bit is your problem, its not hard enough. Do you have a set of cobalt bits? Though I would recommend you not ruin them by trying, they would be your best bet. Most of these magnets have been pressure-fired and a very very hard.
