Plastic drill bits can drill through plastic. These metal drill bits have ground flukes with 90 degree points and 0 degree rake. Plastic drill bits shave or scrape plexiglass, acrylic or plastic away layer by layer. These bits come in a variety of diameters at home improvement or hardware stores. If you are unable to find them locally, many online retailers sell them.

Plexiglass is a clear, plastic, lightweight alternative to glass. Drilling holes in plexiglass can be challenging. Often the traditional drill bits, used for metal and wood, chip and crack it while drilling through its surface. Specialty drill bits prevent the cracking and chipping. You can also alter traditional drill bits to work better with plexiglass.
