American Petroleum Institute Standards for PDC and Rock Bit Tolerances

PDC bits are gauged by either a "go" gauge or a "no go" gauge. 

A "no go"gauge is used to ensure a bit is not smaller than allowed and, as the name implies, it should not go or slip down the entire length of the bit.  A "go gauge ensures a bit is not larger than allowed and should slip down the entire bit.
