[aking828]

Hi All,

I have a part to work by drawings. There is a hole , drill #75. I don't know what the diametre is. Please do me a favor. Thanks!

I have found a drill bit website.

"The No. 75 bit allows drilling of small .021" holes at tape juncture points for easy insertion of 1/8" brads in hardwood or Masonite structures. "

Could I understand that it means No 75 hole is 0.021" ?

yes.
A #75 drill cuts a 0.021" diameter hole.

1) http://en.wikipedia.org/wiki/Drill_and_tap_size_chart
2) Machinery's Handbook (under Drills / straight shank drill sizes /number
3) Any supplier of drills usually gives little pocket charts to carry with you for free.

Good luck
