10 inch x 72 teeth red Perma-Shield solid surface blade. Application: heavy duty solid surface blades for swirl and burn-free cuts. This blade features teeth with a specially designed triple chip grind for leaving swirl free cuts in solid surface materials such as Dupont Corian, Wilsonart Gibraltar and SSV Fountainhead. The laser cut anti-vibration slots reduce the sideways movement of the cutting edge against the solid surface material, dramatically extending cutting life. No need for stabilizers. Perma-SHIELD permanent coating is a superior aluminum alloy coating that helps reduce friction, heat build-up, gumming, and is resistant to rust, which add up to longer blade life.
