I bought it for hole diameter measurement, but I am not using it.

I purchased it because it can be used to measure the hole diameter, but when inserting into the hole gaps will be created as much as the thickness of the gauge. I thought that the graduation was carved considering this, but because the scale is engraved logically (as the thickness of the gauge is zero) it can not be used at all. (It means that it is not a substitute for a vernier caliper)
