Step 1 : Introduction to the question "Deciding that I'd be rather good at DIY, I then bought a 'Carpenters' drill. The fine print was a bit of a 'mouthful', but what did it tell me, that sadly meant the drill didn't have the dual purpose I thought it would?"
...We all dislike visiting the dentist, but here is the proof that the dentist does indeed have the monopoly on all drilling of teeth. Sorry. For clarification, a 'Carpenter's' Drill is "An implement with cutting edges, or a pointed end, for boring holes in hard materials, usually by a rotating abrasion or repeated blow". I'll be honest, it DOES sound frighteningly similar to going to the dentist. Maybe they have a good point.
