Homebrew PCBs

I am drilling holes with #96 (0.006 inch) drill bits.  However, not one hole
has been drilled because the bits are so small compared to the runout of the
tool, they break in half when they touch the workpiece before any drilling
begins.  Copper clad is my workpiece.

 

I tried a Dremel, Dremel flex handpiece, and Marathon 35k RPM micromotor.
All three have too much runout and the bit breaks in half.  Has anyone
successfully drilled holes this small before?  Are there any suggestions for
a drill or rotary tool that has low runout?
