Cutting polycarbonate can be tricky. You need the right tools. This guide helps you pick the best circular saw blade. It will make your cuts smooth and clean.
Key Features to Look For
You need to know what to look for in a saw blade. Here are some important features:
- Teeth Count: Look for blades with many teeth. This is important. More teeth mean smoother cuts. For polycarbonate, choose blades with at least 80 teeth. Some blades have even more!
- Tooth Design: The tooth shape matters. Look for blades with a Triple Chip Grind (TCG) or a Flat Top Grind (FTG). These designs work well with plastics. They reduce chipping and cracking.

- Blade Diameter: Make sure the blade fits your saw. Check your saw’s manual. It will tell you the right blade diameter. Common sizes are 7 ¼ inches and 10 inches.
