If the runout of the dremel is low enough yes.
you can use the highest speed, professional drills run at 20000 rpm and up.
It will also work at 10000 i think. (feed slow)
remember, cutting speed is dependent of diameter, tiny diameter needs huge 
speed.

If you use carbide drills you will want some sort of guiding mechanism for 
the drill.
It is unlikely that you can hold the drill steady ehough to prevent 
breaking.

Some use the dremel drill stand and have good results.
You can make a pivoting drill stand yourself (a lever holding the dremel).

There were complaints about the bad quality of the dremel, and runout.
I think it depends a bit on luck. It is probably better to get a machine 
with precision
ground self centering collets if you are going to buy a new one (e.g. 
proxxon IB-E or
various bigger straight grinders).

Yes.

full speed is fine. I think my software runs at 15,000 RPM

Caution. Carbide is fragile and will break easily.

A drill press of some kind is highly recomended.

Hi,

I use a T-Tech machine like the one on E-bay.

It has a hardware dongle/key and t-Tech has software for it.

It imports Gerber and drill files and will automatically create an 
isolation path around every pad and trace.

It will also put expanding cuts around pads to give those of us who 
have problems soldering a bigger isolation on the pads.

The machines go for $10,000 new, but often with a good discount.
and the software key is $1,200, also you can get a good discount.

Luckily, I got mine second hand at a much lower cost.

I am watching this e-bay auction as if the thing gets a good price, I 
may considder Ballendo's machine.

I'm not sure what software is available that will do what the IsoPro 
from T-Tech does, and at what cost.

I'd hate to sell my machine for $1,000 and find it cost more than 
that for a machine and software and then also that it is not as easy 
to use.

You can see a screen shot in the photos section under Daves Drill and 
then IsoPro Trace.

I can also select a section and 'rub out' an area of the copper.   
This is usefull for things like given more space around SMD pads.

Dave
