Which drill bit to use to drill into the window glass frame?

Hello.

We bought a pleated blind with installation in the glass bead. We are supposed to pre-drill the holes with a 2mm drill. Which drill is best to use for the glass bead? We have new plastic windows and glass bead.

Do you use a masonry drill or a wood drill?

Wood drill, but with a drill guide, otherwise the drill bit will always slip out. Tape crossed over temporarily also works.

What do you mean by Bohrlehre? What should I do with the adhesive tape? Do you mean marking how deep I have to drill?

Wood drill bits, but with a drill guide, otherwise the drill bit will always run out.

Not necessary. Wood drill bits have the necessary tip and the plastic is very soft. Nothing will run out.

I thought it was about glass glass and not and plastic glass, ash on my head,

Sticking is not an option? With us, it even holds really well with the heavy opaque pleated blinds for the floor-to-ceiling windows for almost a year... I wouldn't drill into my beautiful new RC2 windows for anything in the world. And if a little piece of adhesive falls off, you remove the residue and stick it again.
