What are numbered drill bits?
Number drill bit gauge sizes range from size 80 (the smallest) to size 1 (the largest) followed by letter gauge size A (the smallest) to size Z (the largest). Although the ASME B94. 11M twist drill standard, for example, lists sizes as small as size 97, sizes smaller than 80 are rarely encountered in practice.

What is the difference between a 3/8 and 1/2 inch drill?
A 3/8-inch drill accepts a wide range of bits, making it versatile for common tasks around the house. A 1/2-inch drill handles heavier applications. Efficiency: Some drills have keyed chucks that require a tool to tighten and loosen, but many drills have keyless chucks that you can tighten or loosen by hand.

What is the standard size of a drill bit?
Another size related feature to focus on is the size of the drill bit, as we mentioned earlier. The most common drill bit sizes are 1/16 to 1/4″ and most large sets will also include increments up to 1/2″ thick.
What are the sizes of drill bits?
Drill Bit Lengths Jobber-length drill bits are the most common, with a length somewhere between 9 to 14 times the diameter. Screw-machine-length drills arethe shortest available standard sized bits. Aircraft-length drills are extended length drill bits that are manufactured in fixed length such as 4, 6, 8, 12, 18, 24-inch bits, rather than proportional lengths.
How big is 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 are the standard drill sizes?
Range 1 (R1) is shortest in length, more common for sizing production tubing or casing, and ranges from 18 to 22 ft. Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft. Range 3 (R3) is common in casing and also deployed in deep water drilling applications.
