Homebrew PCBs

How important is the RPM of the drill we use on a PCB?



What would the difference be between a 1750 RPM vs a 10k RPM drill regarding drilling on a PCB? (I always thought higher RPM -> lower torque to drill a hole, but I read higher RPM is better?)

There is a dremel I have been using for sometime using HSS bits that I have used on my FR2 boards.

Now that I am going to migrate to a thinner FR-4 substrate, I am looking forward to buying a good minidrill that also has a stand (since I will be using carbide bits)

Does anyone have feedback on these:

They don't seem to make these in the US (they supposedly make them under a different name "Micro-Mark", but I am not sure if they are the same quality)

The price looks like $120 incl. shipping which is a good price for a brand new precision "drill press" don't you think?

If you have any better tools to suggest, I would be glad to know about them!
