[Note: Use a removable marker so that you can remove the mark after cutting the sheet.]

3. Score the plexiglass with a sharp knife or glass cutter through the mark: Score through the line with a knife at least 5-10 times until you make a deep groove. You can use this highly recommended plexiglass scoring knife blade.

4. Turn over the plexiglass sheet and score the other side: Flip over the plexiglass and score it in the same manner through the line.

5. Set the scored part to the edge of the work surface: After scoring both sides, move the plexiglass to the edge of the work surface.it will give you a comfortable position to snap off the scored section.

The portion of the plexiglass that you want to snap off, should be hanging at the edge of the work surface.

6. Hold the plexiglass with a clamp and break the plexiglass through the scored line: use a clamp to hold both parts of the plexiglass. Then apply a sharp downward pressure to the hanging portion and break the plexiglass smoothly. The cut should be clean through the scoring line.

Best Plexiglass jigsaw Blade:

Preparation and Tools

• At first, choose a jigsaw that is designed for cutting plexiglass.
• Choose the right jigsaw blade for plexiglass. Use an uncoated blade with fine teeth. Also, keep some extra plexiglass jigsaw blade nearby for an emergency.
• Take a clamp-on guide to keep the plexiglass in place.
• Use a ruler and marker to draw the line and printer’s tape or masking tape to prevent splintering.
• Put on your safety glass, earplug, mask, and gloves and closed-toe boots to avoid any unwanted incidents.
• Cutting plexiglass with jigsaw requires skill, so it is better to practice on few scarp pieces of plexiglass.

Cutting Plexiglass with A Jigsaw Step By Step

So, you have all the tools in your hand. It’s time to follow the simple process. Follow the steps to learn more;

Step 1: Set the Plexiglass on a Stable Surface

First and foremost, choose a stable surface that supports the plexiglass while cutting. Make sure the plexiglass doesn't fall. If you are cutting edge of plexiglass, use a workbench or table as a workstation. Or for cutting in the middle, use sawhorse as a workstation.

Then, lie your plexiglass over the workstation. Secure the plexiglass with a clamp-on guide along with the workstation. Make sure the plexiglass doesn't slide or wobble.

Step 2: Mark the Cutting Line

Take a ruler to measure the line you are going to cut roughly. Now mark along the line with a marker. It is better to use a dry-erase marker as you can erase the line later. In case of a curved shape, use a round or stencil to mark as you want.

When you mark over the plexiglass, you basically mark on a brown film paper. This paper comes with plexiglass to protect the glass from scratching. However, make sure to draw the line accurately.

Step 3: Safety Preparation

Remember, plexiglass can easily chip when you cut. Make sure that the small pieces don't harm you. So, wear safety glasses, masks, leather gloves, and earplugs before you start. For more safety, you can use masking tape over the cutting line.

Step 4: Start Cutting

Before you start the tool, make sure to plug the saw into an extension cord or wat outlet.

• Cutting Straight line

At first, hold the trigger down and the guide plate against the surface of the plexiglass. For cutting straight lines, start cutting slowly from the edge. After you cross the centimetres, the blade will begin to heat up.

Now you can cut more easily. Don't start with high speed initially. It may break the plexiglass and your jigsaw, as well. When you see the blade begins to pull away from the cutting line, simply turn off the jigsaw. Start again slowly and then increase the speed.

• Cutting Curved line

If you plan to cut shapes with twists and turns, start by drilling a hole. Use a drill bit that is compatible with the glass. For cutting the curved line, you will need a sturdier plexiglass jigsaw blade. Otherwise, the jigsaw blade cannot take the twist and turns.

After making a hole, insert the blade into the hole. You must start the jigsaw at full speed from the beginning. Elsewise, the blade may bend or damage. With the full speed in the blade, use steady pressure to cut throughout the sheet. Follow the cutting line. Make sure the jigsaw doesn't jump off the sheet.

Step 5: Turn Off the Jigsaw and Clean Up Edges

Once you are done with cutting plexiglass with the jigsaw, turn off the machine. Remove the brown film paper and masking tape from the plexiglass. Now, if you see any rough edges, sand the edges with fine-grit paper. Finally, your plexiglass is ready for use as you wanted.

How To Cut Plexiglass With A Circular Saw

Cutting plexiglass with a circular saw is a very easy process. But it can be tricky if you do not have the right knowledge. So please follow the process carefully. A Circular saw is a very wise choice to cut straight thick plexiglass sheets. Cutting with a circular saw is the easiest way to cut plexiglass. A Circular saw gives a smooth edge. You can get a clean and fine cut by using plexiglass. That is why circular saw is very popular among construction workers.

Preparation and tools

• plexiglass sheet
• dry-erase marker
• A flat and straight piece of wood
• A scale
• Clamp
• Eye protector
• Earplug 

Warning: Please wear eye protection at the time of working. Because even a small piece of plexiglass can be very deadly for your eyes.

Warning: You need to be very careful with the speed while cutting a plexiglass sheet with a circular saw. you should run the saw at a slow and steady speed. Because the friction of plexiglass and blade generates heat which can damage the plexiglass by melting it.

Note: Choosing the right blade is the most important factor in the process. Please make sure that the bade you are using is very sharp and has no broken teeth to avoid kickback.

The teeth of the blade have to be evenly spaced with the same size and shape to avoid damage to the edge. You can use a metal cutting blade for cutting the plexiglass sheet.

Note: You need to feed the saw while cutting because the edge of the plexiglass can be melted by the heat and stick to the blade.

Step By Step

• First of all, put on the safety gear because safety is the first priority. Also, a small piece of plexiglass dust can damage your eyes so nothing is important than your eyes.
• Set the plexiglass sheet on a flat straight sawhorse and make sure that it is safe and secure
• Now you need to clamp the sheet with the working surface so that it does not shake while cutting.
• use a marker and a ruler to make a straight line on both sides where you want to cut the plexiglass.
• Then you need to align the circular saw with the line that marked to cut through. You will find a viewer or slot to see exactly where the saw is set to cut. You need to make sure that the saw is line up with the marked line.
• Switch on the saw and bring it to full speed before contacting with the sheet. Do not cut the plexiglass before the saw is reache3d to full speed. The ideal speed for cutting plexiglass is 3450 RPM.
• Please push the saw very slow and steady motion. It is a very important facet of a fine cut.if you run the saw too fast through the plexiglass, it will damage large pieces of sheet and the edges will be very rough. Push the saw very slowly and let the blade cut smoothly. Finally, make sure that the 2 halves are well settled on the sawhorse so that they don't fall after cutting.
