How to Drill Through Auto Windshield Glass

by Jeffery Keilholtz

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.

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.

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.

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.

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.

Tip

  • If excess resin pours over the damaged area, apply nail polish remover to the excess resin and wipe clean. If the crack is long, try drilling through glass at alternate ends of the crack.

Warning

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