S9,
Try to get one with the pin 3", and the TW of around 2-3 ounces. That should be good enough for a variety of drillings. Secondly, NEVER listen to Superman, if he is steering you away from any Saw. I believe that a Saw, in his hands, is more powerful than kryptonite, therefore he cannot throw it.
