Thanks for the advice. I think I didn't choose my words correctly when I mentioned the relationship of a #40 with a 3/32" rivet or a #30 with a 1/8" rivet and so on. All I was asking for, was the relationship between a #10 drill bit and the fractional counterpart, if any.

I won't discuss whether or not my tools are cheap or aviation approved, which is simply an understated assumption, to say the least.
Rest assure the airplane is being built with certified tools and hardware. I would never compromise the construction of a flying machine in which I'd fly my family with.
This was just a little lack of information. Thanks again

On a side note to this ... I have always wondered who came up with the numbering system ... # 30 or #40 .. based on what ?? Inches and ft I get and decimal of an inch .... but numbers and letters ... who came up with that idea ! ;-)

Probably from here -

Stub's Steel Wire gauge
Used for drill rod and tool steel wire. It is the basis of, though not identical to, the numbered sizes of American Standard twist drills.


You can blame the UK in 1884...

Default Numbering System - wire guage

As I understand it, (and I have been spectacularly wrong in the past!) the number refers to the number of times wire stock was pulled through the forming dies. Hence - the confusing relationship between the number and the physical size of the wire. I.e. - more times through the die, smaller diameter. YMMV!
