How to properly drill carb jets?

I have a tuning issue with my 750 Street Demon where the tuning range I need can't really be had with the primary jets and metering rods available from Holley. The primary jets jump from a #82 up to #87 and after lots of messing around with both sizes and all of my metering rods (which are basically all the ones they make, got the full kit) I could really use a #85 jet. I have other primary jets from the tuning kit which I will never use (far too small, like #76-80), is it possible to carefully drill them out and not mess them up? I've heard just using a normal drill bit will leave burrs on the inside surface which can screw up the fuel flow? I would just buy the correct jet if I could but they aren't available and I have at least 2 spare pairs of jets to mess with.

Basically is there a special drill bit that can drill out carb jets properly?

EDIT: And no regular Holley or Edelbrock jets won't interchange, only the secondaries use regular Holley jets. Primaries are specific to the Street Demon only.
