How to Cut Acrylic on a Table Saw


Acrylic sheets -- also known as Plexiglas -- are heavy-grade clear plastic sheets that are useful in several types of construction projects. Because they are plastic, however, these sheets cannot be cut with typical "wood" saw blades. Instead, if you plan to cut a sheet on your table saw, you'll need to install a carbide blade suitable for cutting metals or plastics. This will keep the plastic from shattering or breaking when you begin cutting.

Things You'll Need

  • Carbide blade
  • Install the carbide blade into your table saw. Consult your manufacturer's documentation for directions on how to do this; different saws will have different installation methods.

  • Place the acrylic sheet on the table saw and adjust the guide fence so that the blade lines up with where you wish the cut to be made.

  • Ensure that the blade is not in contact with the acrylic sheet, then turn on the table saw.

  • Push the sheet gently into the blade. Do not try to force the sheet into the blade faster than it can cut; this could cause the motor to overheat and may damage your saw.

  • Continue pushing the acrylic sheet into the blade until you have finished the cut.

Tips & Warnings

  • Depending on the size of the sheet you wish to cut, it may behoove you to have an assistant holding on to the unsupported edge of the sheet while you cut.
