Best Circular Saw Blades for Cutting Plexiglass

Using the right blade to cut Plexiglass with circular saw.

Plexiglass has been here for almost a century now. It was first made in 1928 and commercialized in the 1930s. Soon after, it was used in aircraft windscreens and submarine periscopes. It got even used in World War II in gun turrets and canopies. Nowadays, however, Plexiglass is almost everywhere, and if you are an aspiring woodworker, you will surely deal with Plexiglass in some instances.

One tool perfect for cutting Plexiglass is the circular saw. But when cutting Plexiglass using a circular saw, you should carefully choose the saw blade you will use. Circular saw blades, of course, come in different varieties. Some are perfect for cutting concrete or metal, and some are for cutting wood, Plexiglass, and other plastic materials. So, when choosing a circular saw blade for cutting Plexiglass, it will help if you are guided in the process.

Facts on Cutting Plexiglass You Should Know

Plexiglass is one of the plastic materials made from methyl methacrylate polymers. These polymers are methacrylic acid polymers. Plexiglass is technically referred to as polymethylmethacrylate (PMMA). Yet, plexiglass got other trade names like Acrylite, Acrylplast, Perspex, Lymacryl, Altuglas, Lucite Acrivill, Vitroflex, and Trespex. Nevertheless, its most popular trade name is that of Plexiglas.

Plexiglass is an excellent alternative to glass materials. As a plastic material, it is popular and is almost everywhere. It doesn’t shatter, however, and is very flexible. Moreover, it is transparent but may come in different colors with a 0.93 transmittance factor. For this reason, Because of this, Plexiglass is also referred to as acrylic glass.

What Made A Perfect Circular Saw Blade for Cutting Plexiglass

When choosing a circular blade for cutting Plexiglass, you need to be cognizant of several factors to zero in on the ideal circular saw blade. Here is a rundown of these factors to consider that could help you choose the best circular blade for such type of material: 

Teeth Count

When cutting Plexiglass, it will be best to use blades with more than 70 teeth because Plexiglass needs fine cutting. With more teeth, you can produce more delicate cuts. But with blades with fewer teeth, the cut quality will never be that good. You better reserve your saw blades with fewer teeth for rough-cutting. But for more delicate cuts without chipping, the ideal saw blade would be more than 70 teeth.

Coated Blade

When choosing a saw blade for plexiglass cutting, go for coated blades. With the suitable coating material on the blade’s surface, the saw blade will not generate too much heat as you cut through the Plexiglass. Additionally, when cutting Plexiglass, you should be mindful of heat because Plexiglass is highly reactive to heat. If your saw blade overheats, you will likely see molted edges after cutting. So, it will be best to go for a saw blade with excellent coating against overheating.
