How to make a hole in the installed window tempered glass?

Buy a glass electric drill. When drilling, the drill bit should be at a 45-degree angle to prevent slipping. After drilling the gap, release the drill bit for vertical drilling. At the same time, add some water, drill slowly and drill a hole.

Tempered glass? (Tempered glass/compensation glass) belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, compressive stress is usually formed on the surface of glass by chemical or physical methods. When the glass bears external force, the surface stress is first offset, which improves the bearing capacity and enhances the wind pressure resistance, cold and heat resistance and impact resistance of the glass itself.

Features and advantages:

1. Its strength is several times higher than that of ordinary glass, and it is resistant to bending.

2. Safe use, increased bearing capacity and increased brittleness. Tempered glass is a small fragment without acute angle even if it is damaged, which greatly reduces the harm to human body. Compared with ordinary glass, the quenching and heat resistance of tempered glass is improved by 3-5 times, and it can generally withstand the temperature difference of more than 250 degrees, which has obvious effect on preventing hot cracking. This is a kind of safety glass. Provide qualified materials to ensure the safety of high-rise buildings.

Disadvantages of tempered glass:

The tempered glass of 1 can no longer be cut and processed, so the glass can only be processed into the required shape before tempering, and then tempered.

Although the strength of tempered glass is stronger than that of ordinary glass, tempered glass has the possibility of self-explosion when the temperature difference changes greatly, while ordinary glass has no possibility of self-explosion.

3 The surface of tempered glass will be uneven and slightly thinner. The reason for the thinning is that the glass is softened by hot melt and quickly cooled by strong wind, which makes the crystal gap inside the glass smaller and the pressure greater, so the tempered glass is thinner than before. Generally, the tempered thickness of 4-6MM glass is 0.2-0.8MM, and that of 8-20MM glass is 0.9-1.8mm.. The specific degree depends on the equipment, which is why tempered glass can't be used as a mirror.
