3" & 4" Hook & Loop Sanding Discs – 40 to 2000 Grit Orbital Sandpaper for Wood, Metal & Stone

● Tired of sanding discs that don’t fit small contours or lack the right grit progression? Whether you’re a furniture restorer, auto detailer, or hobbyist jeweler, the right abrasive makes all the difference. Our 3-inch (75mm) and 4-inch (100mm) hook & loop sanding discs deliver a full spectrum from 40-grit (coarse) to 2000-grit (ultra-fine) – one pack handles aggressive stripping, intermediate smoothing, and high-gloss polishing. The orbital-friendly design fits most random orbit sanders, drill attachments, and detail sanders. Use them on artificial stone, wood furniture, metal surfaces, automotive paint, and plastics. No more switching between multiple brands; these discs offer consistent performance, quick change hook & loop backing, and dust-free compatibility. Perfect for DIYers, professional woodworkers, and automotive finishers who demand versatility without breaking the bank.

✨ Key Features – 3"/4" Hook & Loop Sanding Discs (40–2000 Grit)

●
2 sizes in one system – Choose 3" (75mm) for tight curves, corners, and detail work, or 4" (100mm) for larger flat surfaces. Both sizes share the same hook & loop backing.
●
Wide grit range 40 to 2000 – 40–80 (coarse stock removal, paint stripping), 100–240 (intermediate sanding), 320–600 (fine finishing), 800–2000 (ultra-fine polishing). One set covers every stage.
●
Premium adhesive & heat-resistant bonding – Resin-bonded aluminum oxide grain stays sharp longer. Anti-clogging properties reduce dust loading on wood and paint.
●
Hook & loop backing (Velcro®-style) – Fast disc changes without tools. Secure attachment to any 3" or 4" orbital sander pad, drill backing pad, or detail sander.
●
Multi-material versatility – Artificial stone, furniture, wood products, metal, automotive body filler, plastic, fiberglass, and even soft metals like aluminum. Your go-to disc for workshops.
●
Cost-effective bulk solution – Unbranded high quality means you pay for performance, not logos. Perfect for professional shops and home DIYers who need reliable abrasives daily.

❓ Frequently Asked Questions – 3"/4" Hook & Loop Sanding Discs

● Will these discs fit my existing random orbital sander?
Yes – if your sander uses a 3" or 4" hook & loop backing pad, these discs attach instantly. The 3" size is ideal for compact detail sanders (like Festool, Mirka, or Bosch), while the 4" size fits standard 4" orbital sanders. Always check your sander's pad diameter before ordering.
● What’s the advantage of having 40 to 2000 grit in one system?
You get complete control from heavy stock removal to mirror polishing. Start with 40–80 grit to strip paint or shape wood, move to 150–240 to smooth filler, then 400–600 to prep for finish, and finally 1000–2000 to wet-sand or polish clear coat. No need to buy separate packs from different brands – it streamlines your workflow.
● Can I use these discs on curved surfaces like automotive panels or furniture legs?
Absolutely. The 3" discs are specially designed for contoured areas, tight radii, and detail sanding. The flexible backing conforms to slight curves without tearing. For large curves, the 4" disc also offers enough flexibility for gentle contours – just avoid forcing the disc on sharp edges.
● How do I prevent premature clogging when sanding wood or paint?
Use light to medium pressure and let the abrasive do the work. Our resin-bonded aluminum oxide resists clogging, but for best results, vacuum your sander’s dust port or tap the disc occasionally. When sanding paint or softwoods, switch to a fresh disc as soon as you see material buildup – the wide grit range gives you plenty of spares.
● Are these discs suitable for drywall or masonry?
They perform excellently on drywall joint compound (use 120–240 grit) and artificial stone. However, for heavy masonry or concrete, we recommend dedicated zirconia discs. For general drywall sanding, pair with a dust-extraction sander and 150–220 grit for a smooth finish without gouging.
