8-Hole Sanding Discs | 125mm Hook & Loop | 50pc Assorted Grit Pack

These 5-inch (125mm) sanding discs work with random orbital sanders. This 50-pack has grits from 60 to 1000. They use aluminum oxide abrasive and have an 8-hole pattern. You can use them for sanding wood, metal, and painted surfaces. Features and Benefits - Aluminum oxide grain - This abrasive cuts well and lasts a long time on wood, metal, and composite materials. - Hook and loop backing - You can put these discs on and take them off your sander quickly. - 8-hole dust pattern - This pattern lines up with most 5-inch sanders. It helps pull dust away, keeping the disc clean and the air clearer. - Grits from 60 to 1000 - This range lets you do everything from removing a lot of material to fine finishing. Applications - Woodworking - Use grits like 80 for shaping wood. Use grits like 220 for a smooth finish before staining. - Metal Finishing - These discs smooth welds. They also remove light rust from steel and aluminum. - Automotive Repair - They help shape body filler. They also feather paint edges and prep primer for topcoats. Step 1: Mount the Sanding Disc to the Mandrel These 125mm hook and loop sanding discs are designed for easy attachment to a suitable backing pad. The hook and loop system allows for quick changes between different grits, such as moving from a coarse 60 grit to a finer 220 grit. This convenience helps save time when tackling various sanding tasks. The discs are made from Aluminium Oxide, a durable abrasive material suitable for a wide range of surfaces. Ensure your backing pad is clean and free of debris for optimal adhesion and performance, extending the lifespan of each disc. Option A: Standard Screw Mandrel (402) To attach a sanding disc to a standard screw mandrel, first secure the appropriate backing pad onto the mandrel. Then, align the 125mm hook and loop sanding disc centrally on the backing pad. The hook and loop system will securely hold the disc in place. This method is straightforward and effective for general sanding applications. Always check that the disc is firmly attached before operating your tool to prevent it from detaching during use, which can impact finish quality and disc longevity. Option B: EZ Lock Mandrel (EZ402) While these 8-Hole Sanding Discs are 125mm and use a hook and loop attachment, the EZ Lock Mandrel system is typically associated with smaller, specialised Dremel accessories. Our discs are larger and designed for use with standard 125mm backing pads. Therefore, an EZ Lock Mandrel would not be compatible with these particular 125mm hook and loop sanding discs. Ensure you use a backing pad and mandrel designed for 125mm hook and loop discs for proper fitment and safe operation. Step 2: Insert the Mandrel into Your Dremel These 125mm 8-Hole Sanding Discs are designed for larger random orbital sanders, not Dremel multi-tools. Dremel tools typically use much smaller sanding discs and different attachment mechanisms, often with a maximum RPM rating around 35,000. Our 125mm discs are intended for power sanders that accommodate this size, usually operating at lower RPMs, such as 10,000-12,000. Always ensure the sanding disc diameter and attachment type match your tool's specifications for safe and effective use. Step 3: Best Practices for Sanding For optimal results and to maximise how long a sanding disc lasts, always start with a coarser grit from the 60-1000 range, such as 80 grit, and progress to finer grits like 220 grit. Apply consistent, light pressure, allowing the Aluminium Oxide abrasive to do the work. Over-pressing can generate excessive heat, clog the 8-hole pattern, and reduce disc life. Utilise the 8-hole pattern for effective dust extraction, which prevents clogging and minimises swirl marks. Keep the tool moving to avoid concentrating heat in one area and ensure an even finish.
