) Real base material thickness, not nominal material thickness or material thickness with coating.
2
) Damage of the coating on the back side of the plate / profile require a rework of the coating, if the drilling tools
SF BT 22-A or SF BT 18-A were used for drilling the bore hole. If the tool SBT 4-A22 was used for drilling the
bore hole, no damage of the coating on the back side of the plate / profile will occur.
