FAQs
Can I cut Lexan with a circular saw?
Yes, you can cut Lexan with a circular saw, but certain precautions are critical. Lexan is a type of polycarbonate, which is prone to chipping and cracking if cut too aggressively. Use a blade specifically designed for plastics, ideally with a high tooth count (around 80–100 teeth for a 7-inch blade). Make sure to secure the sheet firmly, use a slow feed rate, and avoid excessive pressure. Cutting at high speed may generate heat, causing melting along the edges. Always wear safety glasses and consider using a sacrificial board underneath to prevent blowout on the bottom side.
What type of circular saw blade to cut polycarbonate?
The ideal blade for polycarbonate, including Lexan, has the following characteristics:
-
High tooth count: More teeth produce cleaner cuts. A blade with 80–100 teeth works well.
-
Triple chip grind (TCG): This tooth design alternates flat and angled teeth to reduce chipping.
-
Fine kerf: Thinner blades reduce the material removed, minimizing stress on the sheet.
-
Carbide-tipped teeth: Durable and long-lasting, they maintain sharpness for multiple cuts.
Avoid blades designed for wood or metal alone, as they can cause cracking or rough edges on polycarbonate. Using the right blade ensures precision and extends the life of your saw.
What's the best way to cut Lexan?
For smooth, professional results:
-
Secure the sheet: Clamp Lexan to a stable surface to prevent vibrations.
-
Mark your cut: Use a fine-tip marker or masking tape to guide the saw.
-
Feed rate and speed: Move slowly and steadily. Rapid feeding can cause chipping or melting.
-
Use a sacrificial board: Placing a scrap piece underneath prevents blowout at the exit edge.
-
Finish the edges: After cutting, light sanding or filing smooths minor burrs.
Following these steps ensures straight, clean edges without damaging the sheet or your tools.
What is the best blade for cutting stone veneer?
Cutting stone veneer requires a completely different approach. Use a diamond-tipped masonry blade designed for circular saws. These blades handle hard materials, providing clean cuts without excessive dust or chip damage. Key features:
-
Continuous rim or segmented rim depending on wet or dry cutting
-
Compatible with standard circular saws, preferably with adjustable depth
-
Slower feed rate to avoid overheating and blade wear
While not related to Lexan, understanding this helps differentiate between blades for plastics and harder materials, ensuring you never compromise your project’s quality.
Final Thoughts
Choosing the best circular saw blade for cutting Lexan is essential for clean, chip-free cuts. Prioritize a high-tooth-count, carbide-tipped blade with a triple chip grind, and follow proper cutting techniques like slow feed rate and secure clamping. By understanding the right tools and methods, you can handle polycarbonate sheets with confidence while protecting both the material and your saw. Remember, the right blade makes all the difference, whether you’re working on Lexan, OSB, or even stone veneer in other projects.
