Standard drill sizes

G'day all



Just a quick question about standard drill sizes for pen / pencil kits.



I know the slim lines you use a 7mm drill for the blanks.



what size drills for other kits?



Dont need a list of the kits at this time just the range of drill sizes.



Would I be right in saying 7mm, 8mm and 10mm.







Thanks again
