Bought this to repair the windshield of my car which has a huge crack in it. This drill is tiny (1,5x20mm) so you will need a dremel of sorts to use it. With this drill you make a small hole just in front of the end of the crack, so that the crack has a place to stop. Drill only through the outer layer of glass 'till you just hit the plastic film between the inner and outer layer of glass. Then you will need a glass repair kit (also sold by banggood) to fill the crack with resin.

Muy pequeño, casi perdido en el plástico del paquete, haz lo que dice.

Very small, almost lost in the package plastic, do what it says.
