Carbide bits work best in FR-4 material, HSS will dull very fast but
will not break as easy as Carbide bits. So depends on material and
how much drilling you intend to do.
To get started the Dermmal drill press and high speed tools work
good, and then there are others like it out there too.
I use a shop vac set up to suck up the dust as you drill, helps keeps
the work clear and dust out of you.
Drilling speed I run the Dermmal on High Speed. With these small bits
the higher speed is better.
Safety glasses are a must.
Bit sizes depend on the leads. The smallest I use is .7mm .0280"
upto 2mm .0787".
Dips I normally use .8mm .0315". Resistor depends on wattage, the
1/4 watts that I normally use I use .8mm .0315".
