How to Use
Simply attach the 75mm disc to a compatible backing pad on your orbital sander or angle grinder. Start with a lower grit (320 or 400) to remove scratches or old finishes, then work progressively up to 1000 or 1500 grit for a smooth, polished surface. For wet sanding, apply a little water to the surface to reduce heat and improve the finish quality.
For safe tool use and best practices with abrasive products, refer to guidance from the U.S. Occupational Safety and Health Administration (OSHA) – Abrasive Wheel Machinery.
Frequently Asked Questions
Q: What are silicon carbide sanding discs used for?
A: Silicon carbide sanding discs are widely used for grinding and polishing a variety of surfaces including automobiles, artificial stone, furniture, wood products, and metals. The higher the grit number, the finer the abrasive — so lower grits (320–400) are great for material removal and shaping, while higher grits (800–1500) deliver a smooth, polished finish.
Q: Can these sanding discs be used wet?
A: Yes! These discs feature a waterproof backing, making them fully compatible with both wet and dry sanding techniques. Wet sanding helps reduce friction heat, minimizes dust, and often produces a finer finish — especially useful for automotive paintwork or lacquered surfaces.
Q: What size backing pad do I need for these discs?
A: These sanding discs are 3 inches (75mm) in diameter. You will need a compatible 3-inch / 75mm backing pad for your orbital sander or angle grinder. Hook-and-loop (Velcro-style) backing pads of the same diameter are the most common pairing for discs of this size.
Q: How many discs are included and what grits are in the set?
A: The set includes 30 sanding discs in total — 5 discs each of 320, 400, 600, 800, 1000, and 1500 grit, providing a full range for both rough sanding and ultra-fine polishing work.
