It is often necessary to drill a car windshield glass to repair minor damage. The process requires patience and precision. Chipped glass can be corrected using a windshield glass drill, a suitable drill bit and resin, according to Car Accessories magazine. Repairing glass damage on your own reduces the chances of allowing small dents and cracks to expand, resulting in the expensive total windshield replacement proposition. Contact a windshield specialist for additional details.

Step 1

Clean the damaged area with a towel. Thorough cleaning is essential to ensure residual dirt or glass fibers do not interfere with the drilling process.

Step 2

Measure the hole with the appropriate drill bit. The circumference of the bit should be aligned with the hole. A 1/32 inch bit is a standard size.

Step 3

Drill slowly through the windshield glass surface until the bit reaches the depth of the crack. Drilling a maximum of 1/8 inch into the glass is a safe depth to avoid additional chips or cracks. The perforation creates a void space that allows residual air pressure to be released.

Put 10 drops of curing resin in the hole. Let the resin dry for at least two hours. The curing resin solidifies within the depths of the cracks and removes the evidence of current damage.


  • If excess resin spills onto the damaged area, apply nail polish remover to the excess resin and wipe it off. If the crack is long, try piercing the glass at the alternate ends of the crack.


  • Drill slowly; too much speed and / or pressure can cause additional damage to the glass. Never drill more than half through the windshield glass to avoid causing further damage.
