Is there any common and simple way to punch holes in glass?

1, first we have to buy a professional drill, and then install the bought special drill on the hand drill;

2. Mark the place where holes need to be punched on the glass, and turn on the switch with a hand-held electric drill so that the drill makes an angle of 45 degrees with the glass plane;

3, slowly close to the mark line, advance bit by bit, draw a small nest and pause, then drop water at the mark to play the role of lubrication and cooling, and then follow the previous step to make the drill touch the glass.

4. With the rotation of the drill, the hand drill slowly stands upright, so that the drill is finally perpendicular to the glass plane, that is, a circle is ground;

5. Continue processing. When drilling through the glass, slow down the advancing speed to ensure that there is no big gap on the back of the glass.
