Usually, when we do a DIY project, we’re mostly dealing with cutting wood. We’ve written about its proper cutting techniques, but other materials may need cutting for your project. You may encounter projects that will require plastic cutting with your diamond blade saw.
Plastic can be tricky to cut for some reasons. It can melt due to heat, its surface can be scratched, and the edges of the cut need to be buffed. Fortunately, three techniques can help you cut plastic without the headaches. Depending on the thickness and the cut you want, here are the techniques you have to consider:
How to Cut Curves
If you want to make curved or rounded cuts, using a jigsaw is advisable. Follow the same process as the first two techniques by properly securing the piece of plastic onto your work table with a clamp. Cut the curves onto the plastic like how you would with wood. However, you have to remember to set the speed to the right setting to prevent overheating and melting. When necessary, let the blade cool down before continuing the cut.
How to Cut Thin Plastic Sheets
If you’re going to do a straight cut into a thin plastic sheet that’s at most 1/8 inch, you can use a utility knife. Then secure the plastic with a clamp unto a spacious work area like your workshop table. Mark where you want to cut and then keep scoring the utility knife until a deep groove forms halfway through the plastic.
Perform the same process on the other side of the sheet along the same line you’ve cut. Once you have a groove on the other side, secure the plastic onto the clap then snap off the piece you’ve just cut.
How to Cut Thick Plastic
For plastic that is thicker than 1/8 inch, you’re going to need your circular saw or table saw. Make sure the blade you’re using has teeth that are evenly spaced and close together. In this case, mark the line where you’re cutting with a marker and secure the plastic onto your work table with a clamp. Perform the cut like you would with wood, but remember to pause between cuts to let the blade cool to prevent the plastic from melting.
Cutting plastic doesn’t have to be difficult. With these techniques, you can cut without the hassles. If you need a sharp diamond blade to do the job, check out GilaTools.com for more tips on DIY projects and other relevant construction advice.
