Drilling a hole in Plexiglass is accomplished with a power drill, and a sharp or metal drill bit. Plexiglass can crack and break, similar to glass during the cutting process. Properly securing the Plexiglass with a clamp, and reducing drill friction are key elements of successfully drilling a hole in a piece of Plexiglass.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

Plexiglass
Power drill
Drill bit (Metal or steel piercing bits work best. Glass and tile drill bits are also highly recommended.)
