Drill a glass

To prevent the glass from cracking, you must first lay it on flat surface It is necessary that the glass adjoins on the entire plane to the surface. This is the same prerequisite as when cutting glass. Drill hot glass will not succeed, because when you try to drill, it will crumble into small pieces.

To start drilling safely, make a stencil. To do this, take a small piece of fiberboard or plywood and make a hole in it of the diameter, which is supposed to be drilled in the glass. Before you start drilling, put this stencil in the right place - this will not allow the drill to slide on the surface.

The drilling site must be constantly wetted. For this you can use water.

This can be done in different ways:

  • make a circular border curb-fence of plasticine and pour liquid into it;
  • put around the intended Holes of a wet rag can be drilled so that the water gradually flows into the hole;
  • you can wet the drill from time to time by simply dipping it into the water.

It is necessary to adjust the rotation speed of the electric drill. It should be no more than 400/700 revolutions per minute, i.e., simply speaking, it should be small. It is necessary to work with a drill extremely carefully, without pressing the glass. The deeper the drill sinks into the glass surface, the less you have to press the drill. The less is left to drill, the lower the speed should be. Especially careful to act when the drill goes through. Uniform drilling and regular watering ensure a good result.

If you need a large hole and you work with a crown, then the main thing is to hold the drill so that the crown is strictly parallel to the surface of the glass. Sharp movements from side to side are not allowed. Make sure the cropping goes evenly around the entire circumference and do not allow the crown to eat more from one edge of the circle than from the other.
