I want to drill tiny holes into shells to make widchimes and have been told to buy a diamond head drill bit. Can anyone tell me what size I would need and does it just fit on to a regular drill? I know someone from here will know :) Thank you, Annette.
The size you need depends on the size of what you're going to be trying to string through it--the hole needs to be slightly bigger than whatever's going through it, but I wouldn't make it too much bigger than that. You should be able to find bits that would fit your drill.
I would be using fishing line. I'm just not sure of the mm size I would need. Thanks.
Maybe you could use a needle (inserted into the bit of a variable speed dremel)?
