Plexiglass is a type of acrylic plastic sheet that is commonly used as a glass substitute due to its clarity and durability. While it may not break as easily as glass, it does scratch easily, so it is important to handle and cut it with care. If you need to cut thin sheets of Plexiglass in a straight line, follow these steps:

  1. Place the Plexiglass on a flat work surface.
  2. Use a ruler or tape measure to mark where you want to cut the Plexiglass with a grease pencil.
  3. Carefully score the Plexiglass along the marked lines with a glass cutter, making five to ten passes.
  4. Move the scored section to the edge of the work surface and apply a sharp downward force to break it along the scored line.

For cutting thicker sheets or more complex shapes, power tools such as a circular or table saw can be used. Be sure to use a blade specifically designed for cutting acrylic or metal to prevent damage to the Plexiglass. After cutting, the edges may need to be smoothed with a power saw.

If you decide to cut Plexiglass by hand, make sure it is less than 3/16 inches thick and that it is placed on a clean, flat surface to prevent scratching. The cost of getting Plexiglass cut will vary depending on location and the store you go to.

Yes, a Dremel can be used for cutting Plexiglass up to 1/4 inch thick using the 561 Multipurpose Cutting Bit or EZ476 1 1/2-Inch EZ Lock Rotary Tool. For cutting neat shapes, use bi-metal jigsaw blades with ten teeth per inch or blades that are hollow ground and very sharp, avoiding very fine blades that can melt the plastic.
