Drill Bit Conversion Chart

[pap]

Airstream is always talking about a #30 drill bit.
What size is that in good old English fractions?

Any idea of where there might be a chart found for drill bit #s vs. inches?

Pap,
The conversion for drill bits to rivets are:
#30=1/8"
#21=5/32"
#11=3/16"
The "numbered" drill bits are available at ACE and better hardware stores.

Drill Bit Number 30 is a standard size.

#30 = 0.1285 inches = 03.2639 mm

Therefore, 0.1285 is between 1/8" and 9/64", but closer to 1/8"
