What is the standard size of a drill bit?
Drill bit sizes are written down on paper and etched onto bits 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).
What is the most common drill bit size?
The most common drill sizes I use range from 2-10mm. I bought a set and just replace the worn ones as necessary. A set of drill countersink bits is also really handy for finish carpentry work. Using a drill and countersink bit prevents the wood from splitting when burying the screw head enough for it to be filled over by the decorators.
What size is a number 21 drill bit?
#21 drill bit = 0.1590 inches 0.1590 decimal as a fraction is 159/1000. However, standard fractional drill bits come in intervals of 1/64 inches. Therefore, there are no standard fractional drill bits that are the exact 159/1000 fraction that the #21 drill bit is.
What is standard drill bit?
Drill bits are the cutting tools of drilling machines. They can be made in any size to order, but standards organizations have defined sets of sizes that are produced routinely by drill bit manufacturers and stocked by distributors. In the U.S., fractional inch and gauge drill bit sizes are in common use.
