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.

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