Just saw these at  HF.  Not a complete-coverage set but some nice sizes that could be used for jet drilling.

I'm sure those are "drill shaped objects" from a different continent.  If the only thing you are ever planning to do with them is drill brass, then you'll probably get a couple shots out of them before they go dull.

That said... I wonder how important the true roundness and surface finish is on things like carb jets. Drill bits don't traditionally leave a very smooth finish (or round holes), and if those things are important, then it would be a much better idea to ream to final size instead of drill.
