You can use a small drill, similar to proxxon (or dremel). The better the  
collets and bearings the happier you will be. Proxxon has very good  
collets, i have heard of problems with dremel and co.. Any straight  
grinder or router might be used too.


You also need a drill stand. again there should be no play, so use a  
better quality. I use a homemade pivoting drill press which also works  
very well.

Carbide drills are what you want for higher numbers of holes, but if you  
really only need one or two boards you can use cheap HSS drills. Those can  
be used free-hand without a drill stand/press and also work ok in lage  
power drills as play and runout is generally not an issue. However, the  
glassfiber makes them dull REAL fast.
