No blanks are available with the tip circumference cut pre-made. You will have to hand file it. It is only to clear a tab on bottom disc so do not worry about precision.

Easiest when dealing directly with Abus in Germany is to know the lock model the key is for (model no of padlock, bike lock etc).
I would have sworn it to be either a RH6 or RH5 (both for bike locks) but without a scale in the picture it is sometimes hard.
