Will the car glass crack further after drilling a hole in the crack?

[MaryMarie]

After drilling a hole in a crack on car glass, it generally won't crack further unless subjected to secondary impact. Here's relevant information: 1. Car Glass: Car glass is one of the essential accessories of a vehicle body, primarily serving a protective function. There are three main types of car glass: laminated glass, tempered glass, and zone-tempered glass, which can withstand strong impacts. Car glass is categorized by location into four types: windshield, side window glass, rear windshield, and sunroof glass. 2. Manufacturing: Car glass is produced by heating the glass in a furnace to near its softening temperature, then rapidly transferring it to air grids with varying cooling intensities for uneven cooling. This process creates different stress levels between the main viewing area and peripheral zones of the glass. Typically, glass produced this way is zone-tempered glass.
