Key Features
- Secure Hook & Loop Backing: The hook-and-loop attachment system locks firmly onto compatible orbital sanders and die grinders, keeping each disc stable and vibration-free throughout your grinding or polishing session.
- Alumina Abrasive Construction: Each red disc is engineered with high-quality alumina abrasive grains that deliver a consistent, even cutting action across repeated use cycles — staying sharp longer and reducing the need for frequent disc changes.
- 8-Hole Dust Extraction Layout: Eight precision-punched holes channel grinding debris away from the work surface, helping maintain cleaner working conditions and extending disc life by minimising particle buildup.
- Wide Equipment Compatibility: Fits most 5-inch random orbital sanders, die grinders, air grinders, and power drills — a versatile addition to any workshop or job-site tool kit.

Frequently Asked Questions
Q: Are these sanding discs compatible with all 5-inch orbital sanders?
A: Yes — the 125 mm (5-inch) hook-and-loop backing is designed to fit most standard 5-inch random orbital sanders, die grinders, air grinders, and power drills. Always verify your sander's backing pad size and hole pattern before use.
Q: What materials can these alumina sanding discs be used on?
A: These alumina discs are suitable for use on a wide range of substrates including wood, metal, rubber, leather, stone, and plastic. The five-grit assortment (60–240) covers everything from aggressive stock removal to ultra-fine finishing.
Q: Do the 8 holes actually make a difference for dust extraction?
A: Absolutely. The 8-hole layout is designed to align with the dust ports of compatible sanders, allowing grinding debris to be drawn away through the machine's extraction system. This results in a cleaner work surface, improved visibility, and extended disc life.
Q: How long does each disc typically last?
A: Disc lifespan varies depending on the material being worked and the intensity of use. The alumina abrasive grain construction is engineered for consistent performance across multiple passes, and the 100-piece quantity ensures you always have a fresh disc ready to go.
