How to properly drill carb jets?

Demon 230085 Modular Carburetor Jets - #85 Jet

About $6.- on the demon website.

Trust me i've already looked, those are regular Holley jets. I need this type but in .085" which they don't make:
Demon Carburetion Street Demon Primary Metering Jets 1948

The jets you linked only work on the secondary side.
