Dull bits could do it, though you'd know if the bit was dull because it would be hard to advance the bit.
High speed could do it. Speed + friction = heat.
But, the number one cause of burning while drilling holes (in anything) is not clearing the chips as you drill. I typically remove the bit fully several times as I drill an airway. The chips and dust that get caught in the flutes of the bit will rub against the wall of the airway, and as more chips and dust build up, pressure against the airway wall builds. And again, speed+friction=heat. It might not be the drill bit's fault, it might just be that you need to clear the bit more often.

If you've lingered in the hole a tad long (OK guys, no smutty innuendos) you might need to loosen the compressed chips with the point of a small nail.KurtHuhn wrote:If any seem compressed onto the drill bit, clear them off with a brush of your finger.
