7 Bit
Numbered drill bit gauge sizes range in ascending order from 80 (smallest) to 1 (largest). Thus, drill bit #7 is on the larger side of your standard drill set. Here we will give you drill bit #7 in decimal inches, drill bit #7 in fractional inches, and drill bit #7 in decimal millimeters (mm).
The purpose of this page is to give you an alternate drill bit (approximate equivalent) to drill bit gauge size Number 7 (#7).

What size is a Number 7 drill bit? (#7 drill bit size) Numbered drill bit gauge sizes range in ascending order from 80 (smallest) to 1 (largest). Thus, drill bit #7 is on the larger side of your standard drill set. Here we will give you drill bit #7 in decimal inches, drill bit #7 in fractional inches, and drill bit #7 in decimal millimeters (mm). 7-bit, Amiga, Retro, Commodore. Hello This site is dedicated to devices created for Amiga computers and other dated tech that some describe warmly as retro-computing.
We start by displaying drill bit Number 7 in decimal inches as follows:#7 drill bit = 0.2010 inches
0.2010 decimal as a fraction is 201/1000. However, standard fractional drill bits come in intervals of 1/64 inches. Therefore, there are no standard fractional drill bits that are the exact 201/1000 fraction that the #7 drill bit is. To find the closest gauge wire #7 drill bit equivalent in fractional inches, we round 201/1000 up and down to 1/64 accuracy to get the following:
≈ 3/16 inches rounded down#7 drill bit = 201/1000 inches
≈ 13/64 inches rounded up
Caution: Due to rounding, a 3/16 drill bit will make the hole smaller than a #7 drill bit and a 13/64 drill bit will make thehole larger than a #7 drill bit. Below we converted the fractions to decimals so you can compare more easily:
3/16 = 0.1875 inches
#7 = 0.2010 inches
13/64 = 0.203125 inchesThere are 25.4 millimeters (mm) in an inch. Thus, to convert a #7 drill bit to millimeters, you simply multiply the decimal inches by 25.4 like so:
0.2010 inches x 25.4
= 5.1054 mm
