20 Drill Bit Size Fractional Equivalent
When working with drills and drill bits, it's essential to have the right size and type of bit for the job. One common type of drill bit is the fractional bit, which is measured in inches. However, not everyone is familiar with the fractional sizes, and it can be confusing. In this article, we'll explore the 20 most common drill bit sizes, their fractional equivalents, and provide a handy chart for quick reference.
What are Fractional Drill Bits?
Fractional drill bits are measured in inches, with the size indicated as a fraction (e.g., 1/16, 1/8, 1/4). These bits are commonly used for drilling holes in metal, wood, and plastic. The fractional size refers to the diameter of the bit, with the numerator (top number) indicating the diameter in 16ths of an inch.
