Drill bit sizes are typically measured in inches, but they can also be measured in millimeters (mm) or fractional inches. The drill bit size refers to the diameter of the bit itself. For example, a 1/4-inch drill bit has a diameter of 1/4 inch.
Drill bit sizes are written as irreducible fractions. So, instead of 78/64 inch, or 1 14/64 inch, the size is noted as 1 7/32 inch. Below is a chart providing the decimal-fraction equivalents that are most relevant to fractional-inch drill bit sizes (that is, 0 to 1 by 64ths).
The drill size chart provides a list of standard size drill bits in several measurement systems, including fractional, metric, wire gauge number, and letter. The decimal equivalents of the diameters are shown in both English and Metric units. Fractional sizes are measured in inches, while metric sizes are measured in millimeters.
9 Σεπ 2018 · The fractions used are always in their simplest form, i.e. reduced as far as possible, so 2/64 becomes 1/32 for instance. The drill size chart below gives fractional sizes and their metric conversions up to 1 inch.
2 Φεβ 2021 · Thread sizes are given in nominal sizes, not in actual measurement. For instance, when a screw or bolt measures 5.9mm, it is called a 6mm thread. There are two common methods to write the thread dimensions. 1.Thread sizes in inches are specified by diameter and threads per inch.

The drill bit size chart provides equivalent sizes for letter, metric, wire gauge, and fractional drill bit sizes, allowing the user to select the correct drill bit for their project.
