Diablo Bi-Metal Jig Saw Blades for Plexiglass
The Diablo Bi-Metal Jig Saw Blades offer a 3-5/8 inch blade with 13 teeth per inch (TPI), specifically designed for plexiglass cutting. Its standout feature is the ultra-hardened cutting edge, which enhances blade longevity—lasting up to 5 times longer than standard blades. The blade maintains a cool cutting temperature, reducing the risk of melting the acrylic or plexiglass while delivering smooth, professional cuts. Its optimized tooth design allows for a clean finish without effort or excessive sanding.
Freud Plastic Blade – 10″ Diameter, 80 Teeth
The Freud 10-inch Plastic Blade features 80 teeth with a modified triple chip grind tooth design, ensuring clean and precise cuts across acrylic, plexiglass, polycarbonate, and other plastics. The blade is constructed from Freud’s premium TiCo Hi-Density Carbide blend, which offers long-lasting sharpness and is ideal for industrial and high volume use. It also has a -3° hook angle and cool operation traits that minimize heat buildup, preventing material sagging or melting during cuts.
IVY Classic 7-1/4″ 128 Tooth Aluminum & Plastic Cutting Blade
This 7-1/4 inch circular saw blade from IVY Classic offers 128 teeth designed for cutting light-gauge aluminum, vinyl, and plastics including plexiglass up to 1/8 inch thickness. The precision ground, no-set teeth provide smooth and accurate cuts without tearing or melting the material. Its high carbon alloy steel construction ensures durability. Users should note the blade requires proper rotation following indicated directions for optimal performance.
CMT 222.080.10 Industrial Plexiglass and Plastic Saw Blade
The CMT 222.080.10 is an industrial-grade 10-inch saw blade featuring 80 teeth with an alternate top bevel and chamfer grind. It is engineered for heavy-duty cutting of plexiglass, plastics, vinyl, and laminate flooring without producing heat or melting the material. Its thin kerf (0.110″) and -3° hook angle provide a smooth finish suitable for miter, table, and special saws. This blade is built to handle application demands requiring fine, clean edges.
Irwin Tools 6-1/2″ 140 Tooth TFG Plastic Cutting Saw Blade
The Irwin 11820ZR features a 6-1/2 inch diameter with 140 teeth designed specifically for cutting plastics, plywood, and veneer. The triple-chip grind (TFG) tooth configuration promotes excellent edge quality by reducing chipping and preventing melting. Its 5/8-inch arbor fits most standard saws, making it versatile for many workshop applications where clean and precise plastic cuts are needed.
Buying Guide: Choosing the Best Blade for Plexiglass Cutting
Blade Type and Saw Compatibility
Determine whether you will use a jig saw, circular saw, or specialized scoring tool. Jig saw blades (like the Diablo Bi-Metal) are excellent for detailed or curved cuts, while circular saw blades provide fast, straight cuts on larger sheets. Ensure the blade diameter and arbor size fit your saw model.
Teeth Per Inch (TPI) and Tooth Design
Higher TPI blades produce cleaner cuts with less chipping—ideal for plexiglass. Tooth designs such as triple chip grind (TCG) or alternate top bevel (ATB) reduce stress on the material and help prevent melting. For smooth cuts, look for blades featuring fine teeth and chamfered edges.
Material and Coating
Blades with carbide tips or premium carbide blends increase durability and maintain sharpness longer than standard steel blades. Heat-resistant coatings or special alloys help reduce heat buildup, preventing the plexiglass from melting or warping during cutting.
Cut Thickness and Application
Consider the thickness of your plexiglass sheets. Some blades are designed for thin sheets (up to 1/8 inch), while others can handle thicker or industrial applications. For very thin materials, scoring tools or specialized hook blades can be more effective.
Heat Management
Preventing melting is crucial. Select blades engineered to minimize heat generation, such as those with low hook angles (-3°) and cool cutting technology. Using slower cutting speeds or applying water during cutting can also help maintain cool temperatures.
Cut Quality and Finish
Depending on your project, you may prioritize a smooth finish requiring minimal sanding. Blades with precision ground teeth and optimized tooth geometry provide cleaner cuts, reducing post-cut finishing time.
Durability and Blade Life
High-quality materials and tooth designs enhance blade longevity. While premium blades may have a higher initial cost, their extended lifespan and cutting efficiency offer better value by reducing the frequency of blade replacements.
