Introduction
Jig saws are versatile power tools that can cut through a wide range of materials, including metal, wood, and plastic. However, cutting plexie glass requires a specific type of blade due to its unique properties. In this article, we'll explore everything you need to know about choosing the best

The Importance of Using the Right Blade
The type of blade you use in your jig saw is critical when cutting plexie glass. Using the wrong blade can cause the plexie glass to crack, split, or shatter. Therefore, it's crucial to select the appropriate blade for the job to ensure a clean, safe, and precise cut.
The Type of Blade
When cutting plexie glass, choose a blade with fine teeth. The teeth should be small, close together, and have a large number of teeth per inch (TPI). Blades with fewer TPI and larger teeth are designed for cutting thicker and harder materials, such as metal. However, for plexie glass, you need a blade with extra-fine teeth to avoid melting or fusing the plastic.
The Blade Material
The material of the blade affects its cutting performance and durability. The common materials used in jig saw blades include high-speed steel (HSS), bi-metal, and carbide. HSS blades are the most affordable and ideal for cutting soft materials like plexie glass. Bi-metal blades are more durable and designed for cutting thicker materials. Carbide blades are the most expensive but offer the highest precision and longevity. However, they're not always necessary for cutting thin acrylic or plexie glass.
The Blade Width
Choosing the right blade width is also essential when cutting plexie glass. A narrower blade will reduce friction and heat buildup, which minimizes the risk of melting the plastic. Generally, a blade width of 1/8 to 3/16 inch is perfect for most plexie glass cutting needs.
The Blade Shank
The shank is the part of the blade that attaches to your jig saw's clamp. Two types of shank are available: T-shank and U-shank. T-shank blades are more popular and designed to fit most modern jig saws. They're easy to install and remove, and you don't need any tools. U-shank blades are older and less common, mostly found in traditional jig saw models.
Blade Length
When cutting thicker plexie glass, you might consider using a blade that's longer than the thickness of the material. A longer blade provides a smoother, straighter cut. However, avoid using excessively long blades as they can increase the risk of blade breakage or wandering off course.
Cutting Speed
Cutting plexie glass requires a slower cutting speed than other materials. High-speed cutting can lead to melting or fusing of the material. For best results, maintain a moderate to slow cutting speed, giving the blade enough time to work without generating excess heat.
Cooling the Blade
To avoid heat buildup when cutting plexie glass, it helps to cool down the blade regularly. You can use a lubricant or a cooling agent such as water to prevent the blade from overheating. Alternatively, stop cutting and allow the blade to cool down naturally before resuming.
Maintaining the Blade
After cutting plexie glass, remove the blade and clean it thoroughly. Residual acrylic residue can cause the blade to dull prematurely and affect its accuracy. Also, store the blade in a dry, well-organized place to avoid damage or rust.
