Adjustable rocker arm not drilled for oil hole....

Has anyone seen this or am I the only lucky one? One of my rocker arms doesn't have the oil hole drilled on the top. I've since removed it and drilled it myself. No damage at all to the rocker or shaft. Just curious if anyone else has seen this.

That can easily happen on an machine line... A drill bit that small will break easily... All it takes is the drill bit to break and the ones after it do not get the oil hole drilled...

If the machine operator does not catch all of them, some of them can make it off the line...
