I'm with jerroot.
Do not use a drill bit, use a reamer, by hand. A drill bit can hop out of the hole and skip across your record, destroying it. Or, the flutes can bite into the wall of the hole and gouge the hole, rapidly pulling the record toward the chuck. Since you cannot clamp down a record to a work surface easily, stay away from drill bits.
