5" (125mm) Hook & Loop Dry Sanding Discs – 60 to 1200 Grit Abrasive Sandpaper
If your sanding discs are loading up, tearing, or flying off before the job is done, it's time to switch to a professional-grade dry abrasive. These 5-inch (125mm) hook and loop discs are engineered with premium semi-brittle corundum abrasive and a strong velvet backing to keep you cutting longer. From auto body pros shaping filler and stripping paint, to furniture builders and metal fabricators, this disc covers the full range—from heavy 60-grit stock removal all the way up to 1200-grit fine finishing. The hook backing locks tight during high-speed dry sanding, yet peels off cleanly in a second so you can move through your grit sequence without wasted time or frustration.

❓ 5" Sanding Discs FAQ – Common Questions Answered
- 1. Are these discs suitable for auto body repair?
- Yes, they are widely used in automotive beauty and repair shops. Use 60–120 grit for stripping paint and leveling body filler, 240–400 grit for smoothing and surface prep, and 600–1200 grit for final finishing before primer or paint.
- 2. Can I use these on wood and metal equally well?
- Absolutely. The semi-brittle corundum abrasive is hard enough for steel and aluminum while remaining sharp for hardwoods, softwoods, MDF, and composites. The grit progression works the same—just start coarse and move finer step by step.
- 3. Will the hook backing hold up under heavy pressure?
- Yes, the velvet hook and loop is designed for high-speed orbital sanders. To maximize hold, press the disc firmly onto a clean backing pad and let the tool's own weight do the work; avoid excessive downward force, which generates unnecessary heat and may reduce backing life.
- 4. Are these wet/dry sanding discs, or strictly dry?
- These are strictly dry sanding discs. The resin bond and backing paper are not waterproof, and using them wet may cause the disc to soften, tear, or lose abrasive. For wet sanding, look for discs specifically marked as wet/dry.
- 5. How do I choose the right grit for my project?
- Think of it in three stages: Coarse (60–200 grit) for removing material fast—old paint, rust, deep scratches, rough wood. Medium (240–400 grit) for refining the surface after coarse sanding. Fine (600–1200 grit) for a smooth, ready-to-paint or polish finish. Always progress gradually without skipping more than one grit level.
- 6. Do these discs fit any 5-inch sander?
- They fit any 5-inch (125mm) random orbital sander or backing pad that uses hook and loop attachment. Just check that your sander’s pad diameter is 125mm; if it's a 6-inch pad with a 5-inch disc, it may not center properly. Always match disc diameter to your backing pad size.
