The most heavy duty of coated abrasive discs, full resin bond on vulcanized (cotton fibers treated under intense pressure and heat) fiber backing. Designed for applications ranging from heavy stock removal to surface blending. Used with back up pads on portable angle grinders. Delivering greater durability and faster cutting action than other aluminum oxide discs, the Neon F726 coarse grit fiber disc features a premium aluminum oxide blend for outstanding performance on beveling, stock removal, deburring and blending applications. The heavier fiber backing helps minimize tearing and the full resin bond further enhances the disc's strength. This affordable disc is an excellent tool for use in combination with a right angle grinder or pistol grip air sander on challenging materials, including titanium, soft carbon steels and super alloys.
