I'm installing some floor outlets in an existing concrete floor in an office. This Poke-thru floor outlet made by Wiremold is advertised as fitting a 3" hole turns out to actually need a hole that is between 3-1/16 and 3-1/8". I thought just using a 3" core bit would do it. I don't want to just use a 3" bit and hope the actual hole meets the above limits. So my question is, do I need to get a special core bit for this? Or do 3" core bits generally make a hole a little larger. Seems crazy that the tolerances are so limited.
