If you don't have access to a drill press, but have a Dremel, here is
a way I have drilled small holes in miniature plastic screws or set
screws. Clamp the Dremel to a track that has two surfaces at 90 deg.
I use an old wooden miter box with one side removed. Make sure a
drill bit mounted in the Dremel is parallel to both surfaces. Now
using one of the smaller Dremel collets mount the screw in the Dremel.
The collet has about 1/4" gripping surface. Don't damage the
threads. Now mount your drill (#81, #82, #83 or .32mm, .28mm) in a
pin vise. Don't let any more stick out of the pin vise than needed.
These little drills are fragile. Clamp the pin vise on a block that
will ride in the track and you shim to get it centered and parallel
with the Dremel collet. Don't use too much force or to much speed in
drilling or you will snap the drill. Now drill all the screws you
will need for the next 10 years. I have been successful in drilling
aluminum screws, lots of drill breakage, but not brass or steel.
I have the newest Dremel drill press but it is very hard to get it
really square with the base. It also flexes which makes it difficult
to drill holes square to the base.
