If you find yourself asking, “What size is a R drill bit?” then look no further. In this article, we will uncover the mystery and help you determine the size of a R drill bit. We will discuss the different types of drill bit sizes, how to measure them, and what to consider when purchasing the right size R drill bit.
The Standard Fractional system is the most commonly used system to measure the size of a drill bit. This system uses fractions of an inch as the standard unit of measure, such as 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4 inch.
The Numbered System is a less common measurement system for drill bits, but it is still widely used. This system assigns a number to each size, such as 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, and 92. Each number corresponds to a different fractional size, such as 80 = 1/16 inch, 81 = 5/64 inch, 82 = 3/32 inch, 83 = 7/64 inch, 84 = 1/8 inch, 85 = 9/64 inch, 86 = 5/32 inch, 87 = 11/64 inch, 88 = 3/16 inch, 89 = 13/64 inch, 90 = 7/32 inch, 91 = 15/64 inch, and 92 = 1/4 inch.
Therefore, if you are trying to determine what size a particular drill bit is, you can use either the Standard Fractional system or the Numbered system. For example, if you have a drill bit marked with the number 81, you can determine its size by looking up the corresponding fractional measurement of 5/64 inch.
