Super thin laser cut kerf (small diameter blades only) provides faster, cleaner, more exacting cuts. Perma-Shield coating shields blade against heat, gumming, and corrosion. Durable micrograin titanium carbide tipped teeth are impact-resistant to hold their edge longer. Laser cut stabilizer vents trap noise and vibration and stabilize blade. Laser cut heat expansion slots reduce heat and blade warp. Tri-metal shock-resistant brazing for stronger carbide teeth.
