As well as the reduction in step size as the gauge size decreases. Each step along the horizontal axis is one gauge size.The sizes of number and letter gauge drill bits are similar to American Wire Gauge sizes (only in representation, not the actual gauge numbers). The largest gauge number (e.g. #107) indicates the smallest drill bit size, and as the numbers decrease (#1), the drill bit size increases. After #1, the gauge number ends and letters start with 'A' and continue through to 'Z'. Here, 'A' is the next largest drill bit size after #1, and the pattern continues with 'Z' being the largest.Frequently asked questions The most common drill bit sizes are those that are defined by standards organisations and produced routinely by drill bit manufacturers. In the US, fractional-inch sizes are common, while metric sizes are used in most other countries. In the US, fractional-inch drill bit sizes are standard. ANSI B94.11M-1979 sets standards for drill bit sizes from 1/64 inch to 1 inch in 1/64 inch increments. Metric drill bit sizes are defined by standards organisations and range from 0.2 mm to 25.0 mm. For example, British Standard BS 328 defines 230 sizes within this range. To choose the correct drill bit size for a screw, you can hold the shaft of the drill bit in front of the screw. If you can only see the threads of the screw, the drill bit is the correct size. If you can't see the threads, the drill bit is too big, and if you can see too much of the screw, the drill bit is too small.
