Flap Discs - 4-1/2"Flap Discs 4-1/2" Provide Final Finish For Weld Grinding, Deburring, Rust Removal, Edge Grinding and Weld Seam Blending Applications.
Flap discs 4-1/2" are designed with overlapping layers of abrasive-coated, fiber-reinforced flaps that fan out from a central hub to provide long lasting durability. Units feature overlapping layers, which continually wear away with use to expose fresh abrasive mineral for a fast, consistent cut. Cushioning of the flaps creates a blended finish for most models. Select units feature a grinding aid, which reduces grinding temperatures for processes involving heat-sensitive alloys such as stainless steel, nickel alloys, and titanium. Some flap discs are suitable on a right angle grinder. One-step alternative to bonded wheels and fiber discs, flap discs grind and finish in a single step, making them a time and cost-saving solution. Flexibility provides easy curve lines and contours with less gouging. Available materials Aluminum, Aluminum Oxide, Coated and Non-Woven, Seeded Gel Ceramic, and more. Grades are Coarse, Extra Coarse, Fine, Medium, Super Fine, and Very Fine. Grit types range from 24 - 600 and up to P120. RPMs range from 12,200- 25,0000.
