Carbide-Tipped Steel Teeth—These blades have carbide-tipped teeth that make clean cuts through plastic while being durable enough to make burr-free cuts through metal.

Aluminum-Coated Steel Body—Blades with an aluminum-coated body resist heat buildup when cutting, so they stay sharp and don’t get gummed up with dust and metal shards. Since they stay cool, they won’t accidentally burn or harden the edge that you’re cutting.

Anti-Vibration Vents—These blades also have anti-vibration vents that limit shaking for straight, accurate cuts. They further reduce heat buildup to prevent dulling.

Number of Teeth—When choosing a blade, you'll want to keep in mind the number of teeth and the width of the cut. More teeth will give you a smoother cut; fewer teeth will give you a faster cut.

Cut Width— A narrower cut width makes faster cuts with minimal material loss; a wider cut width increases stability for straighter cuts.

Number of Teeth—Choose blades with more teeth for thin, brittle plastic; choose blades with fewer teeth for thicker, softer plastic.

Cut Width—Blades with a narrower width of cut make faster cuts with less material loss.
