Drilling through auto windshield glass is often necessary to fix minor damages. The process requires patience and precision. Chipped glass can be corrected by using a windshield glass drill, a proper drill bit and resin, according to Car Accessories Magazine. Repairing glass damage on your own reduces the odds of allowing small dings and cracks to expand, thus resulting in the expensive proposition of total windshield replacement. Contact a windshield specialist for additional details.

Step 1

Wipe the damaged area clean using a towel. A thorough cleaning is essential to ensure that residual dirt or glass fibers do not interfere with the drilling process.

Step 2

Size the hole with the proper drill bit. The circumference of the bit should be flush with the hole. A 1/32-inch bit is a standard size.

Step 3

Slowly drill through the surface of the windshield glass until the bit reaches the depth of the crack. Drilling a maximum 1/8-inch into the glass is a safe depth to prevent additional splintering or cracking. Drilling creates a vacuous gap allowing residual air pressure to release.

Step 4

Place 10 droplets of curing resin into the hole. Allow resin to dry for at least two hours. Curing resin solidifies inside the depths of the cracks and eliminates evidence of current damage.
