Frequently Asked Questions
Q: What types of sanders are these 4-inch sandpaper discs compatible with?
A: These 4-inch aluminium oxide sandpaper discs are designed to fit most standard 4-inch hook-and-loop (Velcro-style) random orbital sanders and disc polishers. Always verify your sander's pad diameter before use to ensure a proper fit.
Q: What is the difference between the grit sizes included in this sandpaper set?
A: The set spans grit 60 through 1000. Lower numbers (60–80) are coarser and remove material quickly — great for stripping, shaping, or heavy grinding. Higher numbers (600–1000) are finer and produce a smoother, polished surface — perfect for finishing touches, wet sanding, or prep work before applying paint or clear coat.
Q: Can this sandpaper be used for wet sanding?
A: The finer grits (600–1000) in this set are suitable for wet sanding applications on metal and automotive finishes. Wet sanding with the finer grits helps reduce heat, minimizes scratching, and delivers a smoother, more refined surface finish.
Q: What materials can I sand with this aluminium oxide sandpaper?
A: Aluminium oxide is a versatile abrasive suitable for wood, metal, plastic, drywall, fibreglass, and automotive surfaces. Its durability means it maintains cutting efficiency longer than many other abrasive types, making it a reliable everyday choice.
