3M Scotch-Brite EXL Pressed compact disc XL-UD, 115 mm x 22 mm, 8A CRS

The Scotch-Brite EXL compact disc is ideal for deburring and polishing with its strong and durable bonded non-woven fibre construction. Our bonded EXL compact discs are constructed by blending abrasive and nylon fibres with synthetic resin. The nonwoven is cured and compressed for added strength and durability. Higher density EXL materials can be extremely tough and aggressively abrasive, allowing them to effectively deburr edges and corners without damaging the workpiece. Lower density materials are soft, conformable and provide a finer finish. They are ideal for finishing contoured surfaces. These sanding discs prevent smearing, giving you cleaner surfaces and reducing preparation time. They are available with silicon carbide or aluminium oxide abrasive mineral. Silicon carbide is a very sharp-edged, synthetic abrasive commonly used for low-pressure applications such as painting and finishing work. Aluminium oxide is a hard, blocky mineral with a high removal rate and long durability. Although silicon carbide removes faster than aluminium oxide, it produces a finer finish. Compact products are durable due to their production process. The compression and hardening of multiple layers of abrasive creates a tough and dense abrasive that can be used for heavy deburring and polishing tasks. The discs are mounted on a 114.3 mm backing pad with a 22.23 mm diameter centre hole to achieve the correct angle on the turning tools. Scotch-Brite abrasives are unique products for surface finishing. The abrasives are bonded in a non-woven fibre matrix. The combination of abrasive and non-woven material creates an abrasive system that achieves consistent results throughout the life of the product. The open non-woven structure enables cool sanding and is dust-repellent, so that the nylon fibres retain their high removal rate because they do not clog.
