Susan these are the hand held drill bits I told you about.
In the top picture starting on the left the little one is 5/64 and they go up to 5/32 which is really big. I use the 5/64 the most and the 3/32. The ones on the right were teeny bits that I had and I made the handles for them. Bake the bits in the clay and then take them out and use a cyanoacrylic glue to glue them back in. They are great for making little holes in clay to add wire or tubing or whatever.
Hope this helps.
