Simple, what you need is a reduced shank bit.

Drill bits have softish shanks, so you can reduce then yourself if you have a lathe.

Commonly called 'Blacksmiths Drills' - why? Haven't a clue!

Pretty big drill for a hand drill. Can you get away with a step drill?

[neurofen]

thanks, the step drills a good idea and i saw one for a about 5 dollars(uk) just around the corner. doesnt have to be to precise, but i'll keep an eye out for the blacksmiths bits, by the looks of it eveyone sells em.

You might try "googling" Silver & Deming drills.
