10 x 80 Teeth red Perma-SHIELD. Application: for ultra long life in double sided manmade materials. Designed to give long life and excellent finish on the top and bottom of laminates, melamines & veneered plywood. The laser cut anti-vibration design yields the plate acoustically dead. This reduces sideways movement of the cutting edge to prevent chipping in manmade materials such as laminates. This dramatically extends cutting life and finish. No need for scoring blades. 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.
