This is a brand-new, trade-quality sanding flap disc set. Each disc measures 115mm (4 1/2 inches) and has an 80-grit rating. Ideal for 4 1/2'' (115mm) angle grinders and sanders, it's great for removing rust, grinding welds, parting lines on castings and carbon steels, and smoothing rough edges on various surfaces. We also have a 40-grit option in stock for finer work. These flap discs feature high grain adhesion, lasting up to 25 times longer than conventional sanding discs. They fit directly onto an angle grinder without a backing disc, and with different grit options, you can finish your tasks much faster. We've sold many of these to garages, proving their quality and affordability. They're usually sold for about £1.99 each in specialty stores. Always wear goggles when using this tool. Specifications: Size - 4 1/2” (115mm), Aluminium Oxide backing pad, 40 grit available, Internal diameter - 22.2mm.

Using this sanding flap disc is easy. First, make sure your 4 1/2'' (115mm) angle grinder or sander is turned off. Then, attach the flap disc directly to the tool without the need for a backing disc. When you're ready to start, put on your goggles to protect your eyes. Use the disc to remove rust, grind welds, or smooth rough edges on surfaces. If you need a finer finish, you can switch to the 40-grit option we have in stock. After use, clean the disc and store it in a dry place. This will help it last longer and keep it in good condition for your next project.
