Cermet II (Ceramic and Metallic) teeth deliver a more efficient and productive metal cutting solution through high heat tolerance and increased hardness for superior wear, fewer blade changes and up to 25X longer life versus standard grinding discsUp to 50X cooler cuts with a circular saw blade when compared to a grinding disc that increases temperature of steel by up to 500 degrees; grinding discs increase the temperature enough to permanently discolor the steelUp to 10X faster cuts with a circular saw blade for maximum productivity and efficiency, resulting in up to 60 seconds faster cuts in both metals and stainless steels versus standard grinding discsTriple Chip Cutting action reduces sparks and the possibility of needing "hot" permitsOptimized blade design reduces wandering and deflection of metal, creating precise cuts that require virtually no re-workAdvanced laser-cut stabilizer vents trap noise and vibration for maximum stability, keeping the blade cool for straight, accurate cutsTri-Metal Shock Resistant Brazing, a three-metal brazing system, allows Cermet II teeth to withstand extreme impact for maximum durabilityLaser-cut thin kerf design provides less resistance and heat build-up for ease of cut, accuracy and long cutting life in cordless or corded sawsPerma-Shield® coating resists heat build-up by protecting the blade against gumming and corrosionLaser-cut arbor reduces vibration and premature wear for accurate blade rotation when in useCircular saw blades create a controlled cutting action resulting in larger chip sizes that generates less dust and airborne contaminates versus standard grinding discsCuts 1/8"-1/2" wall thickness in steel studs, angle iron, flat bar, channel, and EMT conduitCuts 1/4"-1" wall thickness in plate and bar stockCuts 1/2"-2" diameter threaded rod
