& Dry Sanding Discs | Universal Abrasive Paper | Wood & Metal Polishing

These general-purpose sanding discs use silicon carbide grit for good wet or dry sanding. The hook and loop backing lets you quickly change them on your random orbital sander. They come in many sizes and grits for car, woodworking, and metal polishing jobs. Features and Benefits - Silicon carbide abrasive - Stays sharp for a fast cut and an even finish, especially on hard surfaces. - Waterproof paper backing - Resists tearing and stays together when wet sanding, which helps cut down on dust and clogging. - Hook and loop attachment - You can swap grits in seconds on any compatible 6-inch (150mm) sander. - Available in various grits - Covers the whole process, from initial material removal with coarse grits to fine finishing with high grits. Applications - Wet sand car paint to level the clear coat and remove flaws before buffing. - Dry sand wood projects to get a very smooth surface ready for stain or a final finish. - Use on metal to remove rust or get the surface ready for polishing and finishing. Step 1: Mount the Sanding Disc to the Mandrel Properly attaching your sanding disc is key for effective and safe operation. These universal abrasive paper discs are compatible with standard backing pads that accept hook and loop attachments. Ensure the disc is centred on the backing pad to prevent wobbling during use. A secure attachment also helps to maximise the lifespan of your sanding disc by distributing wear evenly. For optimal results, check that the disc lies flat against the backing pad before starting any work. Option A: Standard Screw Mandrel (402) To fit a sanding disc to a standard screw mandrel, first place the backing pad onto the mandrel’s threaded post. Secure it tightly with the retaining screw or nut, ensuring there is no play. The hook and loop surface of the backing pad will then securely hold the sanding disc. This method provides a robust connection for tasks involving metal and woodworking, offering stability even at higher RPMs. Always double-check the tightness before operating your tool. Option B: EZ Lock Mandrel (EZ402) The EZ Lock mandrel system offers a quick-change solution for attaching your sanding discs. Simply align the backing pad with the mandrel's locking mechanism and press firmly until it clicks into place. This system simplifies disc changes, which is particularly useful when alternating between different grits, such as an 80 grit for aggressive material removal and a 220 grit for finer finishing. The quick-release feature does not compromise the security of the disc during operation. Step 2: Insert the Mandrel into Your Dremel Once the sanding disc is securely mounted on the mandrel, insert the mandrel shank into the collet of your Dremel rotary tool. Tighten the collet nut firmly using the collet wrench to prevent the mandrel from slipping during operation. Ensure the mandrel is inserted as far as it will go into the collet for maximum stability and to reduce vibration. This setup is suitable for both dry and wet sanding applications on materials like metal and wood. Step 3: Best Practices for Sanding For best results and to prolong the life of your sanding disc, apply light, even pressure. Avoid pressing too hard, as this can overheat the material, clog the disc, and create swirl marks. Move the tool consistently across the surface, especially when using random orbital motions. Periodically check the disc for wear; a worn disc will be less effective and can scratch your workpiece. For wet sanding, use a suitable lubricant to reduce heat and improve finish. These 75mm, 125mm, 150mm discs perform well across various tasks.
