When using a drill bit for a feeler gauge, please remember that many drill bits are actually undersize at the shank end of the drill bit so please use the above bit sizes with a grain of salt!

Also note that to correct for a broad feeler gauge or a loose-fitting drill bit:

ROC =^(D²-W²)/_8T

Where:

W = the width of the feeler gauge, or if the drill bit can be moved back and forth under the straight edge by the total amount W
D = mirror diameter,
T = gauge thickness or bit diameter.
