IRWIN Lettered and Numbered Drill Bits information:

Letter and numbered drill bits were developed to make up the gaps in between metric and fractional sizes. The most common use is for using taps. There will not be an exact match for fractional sizes but you can refer them to closest fractional bit that is larger than the numbered bit.
