Best saw for cutting plastic: How to Cut Thick Plastic Using a Saw

Saws such as table saws, fine-toothed, circular saws,  jigsaws, and hacksaws are the best for cutting thick plastic.

While a fine-toothed saw and hacksaw cuts thick plastic, thicker and harder plastic requires a jigsaw or a table saw.

Using any powered saws above, use a non-melting saw blade designed to cut plastic. Using a regular blade may generate heat and melt the plastic.

Use the below step when using a saw to cut plastic.

  1. Use a permanent marker to draw the cutting line on the plastic.
  2. Secure the plastic in place using a clamp.
  3. Cutting through the marked line using your chosen saw
  4. If using a table saw, pass the plastic’s cutting line through the saw’s blade, as you would when cutting wood.

Best saw for cutting plastic: How to Cut Plastic Using a Drill

A drill works as a cutting facilitator rather than the actual cutter. Since cutting hard plastic using a knife or a saw can be tedious, using a drill to make holes in the plastic makes cutting easier.

Therefore, this method requires a utility knife, a drill, and drill bits. Then follow the following procedure.

  • Mark the cutting line on the plastic’s surface.
  • Draw small holes evenly distributed along the cutting line; ensure they are as close as possible.
  • Attach the smallest diameter drill bit to the drill.
  • Begin drilling on the marked holes to weaken the plastic cutting line.
  • Use a knife to cut along the drilled hole until you cut the plastic.

Hot Knife

You can also make a hot knife using a soldering iron to cut through the plastic.

Although this method may be time-consuming, it can be a long-term DIY method for home plastic cutting.

This method requires a soldering iron, utility knife blade, and M5 screw.

How to make a hot knife to cut plastic

Identify the marks on the knife blade and snap a small portion of the knife blade through the marks.

  1. Using a screwdriver, unscrew the soldering iron tip and remove it.
  2. Put the M5 screw inside the empty hollow of the soldering iron.
  3. Mark the top of the screw according to the blade size you snapped.
  4. Remove the M5 screw from the soldering gun and clamp it tightly with the top facing up.
  5. Using a hacksaw, deepen the mark on the screw to around half an inch.
  6. Put the blade inside the groove and screw the M5 screw tightly inside the soldering gun.
  7. Plug the soldering iron in power and wait for it to heat.
  8. You can then use your homemade hot knife to cut plastic.

How to Use String For Cutting Plastic

This traditional method, friction sawing, is suitable for cutting thin plastic. For this method, use a Nylon or Polyester thread.

  1. Test if the string is breakable by pulling its ends. If it stays intact, it’s up to the task.
  2. Mark the area you want to cut and make a small hole there.
  3. Pass the string through the hole, moving it back and forth while holding both ends rapidly.
  4. It will create friction which cuts the plastic effectively.


To cut through plastic, the choice of the saw or tool you use depends on the thickness of the material.

Ensure you select the above tools depending on your project.

Also, wear protective gear such as masks, goggles, and gloves.
