Diablo Bi-Metal Jig Saw Blades for Plexiglass
Diablo’s jig saw blades are engineered to stay cooler, reducing heat-related melting in plexiglass cuts. The 3-5/8 inch blades feature a 13 TPI configuration that balances speed and control, delivering smooth, melt-free cuts suitable for precise plexiglass work. The blades offer up to improved life, thanks to an ultra-hardened cutting edge, making them a solid choice for repetitive plexiglass tasks. Optimized tooth geometry enhances efficiency for fast, clean finishes on plastic applications.
CMT 222.080.10 Industrial Plexiglass and Plastic Blade
This 10-inch blade with 80 teeth is designed for heavy-duty plastic and plexiglass, offering smooth finishes with minimized melting. It is suitable for radial arms, miter saws, and table saws. The blade’s kerf and grind specifics support thin plastic cutting and reduce heat buildup, making it a practical option for larger plexiglass sheets and multi-angle cuts.
CRAFTSMAN 7-1/4 Inch 140 Tooth Finish Blade
Craftsman’s 140-tooth blade provides maintained accuracy for plywood, OSB, and plastic cuts. Its fully hardened plate preserves true cuts, while precision-ground teeth deliver a smooth finish. The heavy-gauge steel design aims to extend blade life, supporting repeated plexiglass tasks without frequent blade changes.
IVY Classic 35050 Swift Cut 7-1/4″
IVY Classic’s Swift Cut features a 7-1/4 inch, 128-tooth design optimized for aluminum, plastic, and vinyl siding up to 1/8 inch thick. The blade uses high-carbon alloy steel with precision-ground teeth to minimize wandering and deliver smooth, accurate cuts. Direction arrows guide safe operation, and the blade is suited for light to medium plastic cutting tasks.
IVY Classic 35056 Swift Cut 10″ Blade
This 10-inch blade with 200 teeth is designed for aluminum and plastic cutting. It emphasizes a narrow kerf and precise geometry to reduce heat buildup and maintain a clean cut in thinner plastics. The blade’s 5/8-inch arbor ensures compatibility with common circular saws, supporting stable, controlled operation.
FOXBC 10-Inch 80-Tooth TCG Blade
The 10-inch FOXBC blade features a 80-tooth design with a 5/8-inch arbor, optimized for aluminum, non-ferrous metals, and plastics. Its kerf measures 0.094 inches, with laser-cut stabilizer vents to reduce vibration and trap noise. The high-density tungsten carbide construction contributes to toughness and long life for plastic cutting tasks that require accuracy and durability.
Benchmark Abrasives TCT 6 1/2 Inch Blade
Benchmark Abrasives offers a 6 1/2 inch tungsten carbide tipped blade designed for non-ferrous metals, plastics, and composites. Its carbide tips improve durability and provide clean, burr-free cuts. The blade is suitable for lower RPM dry-cut saws and trusted for reliable non-metal cutting across plastic applications.
Buying Guide
- Material compatibility: Choose blades explicitly rated for plexiglass or plastics to minimize heat buildup and prevent melting.
- Tooth design: Fine-tooth blades (high teeth-per-inch) produce smoother cuts in thin plastics, while aggressive teeth are better for thicker or composite materials.
- Blade material: Carbide-tipped and high carbon steel blades offer different balances of durability and cost. Carbide tips tend to last longer on plastics.
- Arbor and kerf: Ensure the blade arbor size matches your tool (commonly 5/8 inch) and consider kerf for material removal and heat generation.
- Tool compatibility: Verify the blade is suitable for your saw type—jig saws for curved cuts and circular saws for straight cuts or angle work.
- Heat management: Blades designed with optimized tooth geometry and cutting edges reduce heat, which helps prevent plexiglass from melting during cuts.
- Durability vs. cost: For frequent plexiglass work, investing in carbide-tipped or hardened-edge blades may reduce replacement frequency and provide consistent results.
- Safety: Follow manufacturer instructions, secure the workpiece, and use appropriate eye and hand protection when cutting plastics.
