● Sanding hard materials like steel, hardwood, or gel coat requires a disc that stays sharp and doesn't clog. Our 5-inch (125mm) wet & dry sanding discs feature a 6-hole dust extraction pattern that pulls debris away, keeping the abrasive cutting efficiently. The hook & loop backing attaches instantly to any 5" random orbital sander or drill pad, while the durable aluminum oxide grain with self‑sharpening ceramic properties delivers consistent cut from 80 grit (coarse) to 800 grit (fine). Use dry for fast material removal on rust, old paint, and varnish, or wet for a lubricated, heat‑free finish on gel coat and automotive surfaces. Perfect for metal fabrication, shipbuilding, hardwood flooring, stone polishing, and auto body work. Whether you're removing heavy paint, blending welds, or prepping surfaces for coating, these discs offer high cutting performance, long life, and a dust‑controlled workspace.
✨ Key Features – 5" 125mm 6-Hole Wet/Dry Sanding Discs (80-800 Grit)
●
6-hole dust extraction design – Reduces clogging and keeps the disc cutting cooler during dry sanding. Perfect for use with dust‑extracting random orbital sanders.
●
Wet & dry dual‑use capability – Fully waterproof. Dry sand steel, hardwood, and paint; wet sand gel coat, varnish, and stone for a finer finish without dust.
●
Self‑sharpening ceramic‑enhanced grain – Long‑lasting aluminum oxide with self‑sharpening properties maintains a constant cut over extended use. Ideal for hard materials like stainless and hardwood.
●
Grit range 80–800 (expandable to 8000) – 80‑120 for aggressive stock removal (rust, weld spatter, old paint), 150‑320 for intermediate smoothing, 400‑800 for fine finishing. Higher grits up to 8000 available upon request.
●
Hook & loop backing (Velcro® compatible) – Quick disc changes on any 5" random orbital sander, detail sander, or drill‑mounted backing pad. Secure grip under heavy pressure.
●
Multi‑industrial application – Metalworking (steel, stainless), shipbuilding, parquet & hardwood flooring, artificial stone & granite, automotive paint & gel coat, Corian, and light weld blending.
●
High cutting performance & durability – Engineered for powerful grinding of tough materials. Removes paint, varnish, rust, and hard coatings efficiently without premature wear.
❓ Frequently Asked Questions – 5" 6-Hole Wet/Dry Sanding Discs
● Will these discs fit my random orbital sander's dust collection?
Most 5" random orbital sanders from major brands (DeWalt, Makita, Bosch, Mirka, Festool) use either a 5‑hole, 6‑hole, or 8‑hole pattern. The 6‑hole design is widely compatible – even if your sander has a different hole count, the disc will still attach securely and provide better dust pickup than a solid disc. For best results, align the holes as much as possible.
● Can I use these discs for heavy paint removal on hardwood floors?
Absolutely. Use 80‑120 grit for aggressive removal of old varnish, paint, or polyurethane on hardwood. The self‑sharpening grain resists clogging from soft finishes. For best results, dry sand with a dust extractor connected – the 6 holes will pull away most of the dust. Follow with 150‑220 grit to smooth the wood before recoating.
● What's the advantage of self‑sharpening ceramic‑enhanced grain?
Traditional abrasives dull quickly on hard materials like steel, stainless, or dense hardwoods. Self‑sharpening grains fracture at a microscopic level, exposing fresh cutting edges continuously. This means the disc maintains a consistent cut for much longer – you'll notice fewer disc changes and less effort when sanding tough surfaces like weld seams or gel coat.
● Can I wet sand with these discs, and what materials benefit most?
Yes, the discs are fully waterproof. Wet sanding is highly recommended for gel coat (boat repair), automotive clear coat, stone polishing, and any application where dust control is critical. It also reduces heat buildup, which prevents warping or melting on plastics and composites. For metal, dry sanding is usually faster, but wet sanding can be used for final finishing on stainless.
● Do you offer higher grits beyond 800 for fine polishing?
Yes. While our standard stock focuses on 80–800 grit for heavy to medium work, higher grits up to 8000 are available upon request for ultra‑fine polishing (e.g., 1000, 1500, 2000, 3000, 5000, 8000). Please contact us via the “Ask a question” tab for custom grit assortments or bulk orders.
