A new line of ceramic flap discs from Rex-Cut Products Inc. that provides aggressive and controlled stock removal has been added to the Sigma Green line of fast grinding specialty products. Rex-Cut Sigma Ceramic Flap Discs feature ceramic abrasive grains bonded to a treated material that is layered and stacked in a way that provides aggressive and controlled stock removal with minimal pressure. Self-sharpening and durable, these standard density Type 29 discs are suited for use on stainless steel, mild steel, and exotic metals.

The flap discs are available in 4.4-in., 5-in. and 7-in. diameters by 0.875-in. sizes and offered in 36- and 60-grit versions, with or without hubs. The company said the flap discs run cool, produce a better surface finish and last longer than alumina oxide abrasives. They are available with 5/8-11 adapters.
