This is a 30-piece set of 5 inch 125mm sanding discs for your random orbital sander. The pack includes a mix of different grits, so you have what you need for every stage of a project, from initial stripping to final finishing on wood and metal. Features and Benefits - Mixed Grit Assortment - Includes coarse, medium, and fine grits for a complete sanding process. - Hook-and-Loop Backing - Lets you swap out discs in seconds without dealing with messy adhesives. - 8-Hole Dust Extraction - The pattern lines up with most 5-inch sanders to pull dust away from the surface. - Aluminum Oxide Abrasive - An effective material for sanding both wood and most common metals. Applications - Using a coarse grit disc to remove old paint or smooth a rough wooden board. - Working through medium grits to remove scratches left by the initial sanding. - Finishing with a fine grit to prepare a surface for a glass-smooth coat of paint or varnish. Step 1: Mount the Sanding Disc to the Mandrel Option A: Standard Screw Mandrel (402) Attach the 125mm hook and loop sanding disc to a standard screw mandrel. Ensure the hook and loop backing pad on the mandrel securely grips the disc. These discs are designed for woodworking, metal grinding, and polishing. Make sure the disc is centred to avoid wobble and uneven sanding. This method is suitable for general sanding tasks across various applications. Option B: EZ Lock Mandrel (EZ402) For quicker changes, consider using an EZ Lock mandrel. The 125mm hook and loop sanding disc attaches effortlessly to this type of mandrel. Simply press the disc onto the hook and loop surface for a secure fit. This system streamlines disc changes, allowing you to move efficiently between different grit sizes or materials during woodworking or metal grinding projects. Step 2: Insert the Mandrel into Your Dremel Once the 125mm sanding disc is securely mounted on your chosen mandrel, insert the mandrel shank into the collet of your Dremel rotary tool. Tighten the collet nut firmly to prevent slippage during operation. Always ensure the tool is unplugged or the battery removed before changing accessories. This setup is ready for your woodworking, metal grinding, or polishing tasks. Step 3: Best Practices for Sanding When using these 125mm hook and loop sanding discs, apply light, consistent pressure. Move the tool steadily across the surface to avoid swirl marks. For optimal results and to prolong disc life, start with a coarser grit for material removal (e.g., 80 grit) and progress to finer grits (e.g., 220 grit) for a smoother finish. The longevity of a sanding disc depends on the material being sanded and the pressure applied. Avoid excessive speeds over 20,000 rpm on delicate materials.
