What is run-out? Run out is differences or variations in the diameter of a cutting tool at certain points along the outside edge while the tool is rotating. When an end mill is in rotation it is important that each tooth hits at the exact same spot along the work piece.  If one tooth is hitting the work piece more than the others then that tooth is doing the bulk of the work.  This will cause the end mill to wear and breakdown more quickly.
