A full line of cotton fiber quick change abrasive discs for blending and finishing stainless steel, aluminum, and exotic alloys are available from Rex-Cut Products, Inc. of Fall River, Massachusetts. Rex-Cut Cotton Fiber Quick Change Discs incorporate multiple layers of reinforced non-woven cotton which are impregnated with abrasive grains and then pressed, bonded together, and fitted with 3M Roloc and Sockatt style fasteners. Constantly exposing fresh abrasives as they work, these quick change discs grind and finish in one-step with smooth operation. Flexible for use on flat and contoured surfaces, yet rigid enough to reach into corners, Rex-Cut Cotton Fiber Quick Change Discs last up to 25 times longer than unitized discs, claims the firm. Impregnated with either aluminum oxide or silicon carbide abrasive grains, they come in 1", 1-1/2", 2", and 3" sizes in a variety of grits with flexible and medium bonds. Rex-Cut Cotton Fiber Quick Change Discs are priced according to size and quantity. Free samples are available upon request. Kits are also offered.
