MessageHello Alan and List
The "number" drills are used by the model engineering fraternity. I have =
a case of them. My case numbers the drills from 1 - 60 and they are =
"wire guage".According to my micrometer the No.1 drill measures 0.028" =
(across the flukes) and the No.60 drill measures 0.040". No.37 is 0.104"

  Here's a very useful page to have a printed copy of in your reference =
materials. I found it while researching the question which follows:

  http://www.saw-online.com/Tips/drill.htm

  Question: They say to use a #37 drill bit when cleaning out action =
center cloth from flanges, etc. What the heck is a #37 bit? Is it the =
"wire size " 37 shown on the chart above?

  Metric?

  Alien?
