Description
This product is a 4-1/2-inch diameter Type 27 (flat) flap disc featuring premium ceramic abrasive grains bonded to high-strength polyester sanding flaps with a reinforced fiberglass backing plate. It is designed for superior performance on heat-sensitive and hard-to-grind materials. The disc integrates a cool grinding aid to reduce heat buildup, making it ideal for grinding aerospace alloys, stainless steel, carbon steel, nickel alloys, cast iron, aluminum, and exotic metals. The compact “Hybrid” flap design enhances edge strength for demanding grinding applications and outperforms zirconia flap discs by up to 50% on stainless steel, carbon steel, and exotic alloys. Its ceramic abrasive is self-sharpening, ensuring consistent cutting performance throughout its usable life, requiring less pressure for aggressive stock removal, and reducing the frequency of disc changes. The disc is contaminant-free, with less than 0.1% iron, sulfur, and chlorine, preventing after-rust or surface contamination on corrosion-sensitive materials.
