● From heavy paint stripping on car bodies to mirror‑finish polishing on hardwood floors and gel coat, you need a disc that cuts fast, stays sharp, and keeps dust under control. Our 5‑inch (125mm) 8‑hole wet & dry sanding discs feature a ceramic and high‑quality alumina blend that self‑sharpens for constant cut over long periods. The 8‑hole dust extraction pattern works with vacuum‑equipped orbital sanders to remove sanding dust, reduce clogging, and extend disc life. The open coated anti‑clog topcoat prevents loading on soft materials like varnish, paint, and gel coat. Use dry for fast stock removal on steel, rust, and welds, or wet for a lubricated, dust‑free finish on clear coat and stone. From coarse 60‑grit to ultra‑fine 10000‑grit, this single disc family handles grinding, sanding, and polishing across metalworking, shipbuilding, parquet flooring, automotive repair, and woodworking. Perfect for orbital sanders, mini DA sanders, universal hand grinders, and mini air polishers.
✨ Key Features – 5" 125mm 8-Hole Wet/Dry Sanding Discs (60-10000 Grit)

❓ Frequently Asked Questions – 5" 8-Hole Wet/Dry Sanding Discs
● Will the 8‑hole pattern fit my random orbital sander?
Most 5" random orbital sanders from brands like DeWalt, Makita, Bosch, and Mirka use either 5‑hole, 6‑hole, or 8‑hole dust extraction patterns. The 8‑hole design is widely compatible – even if your sander has a different hole count, the disc will attach securely and provide much better dust pickup than a solid disc. For best vacuum extraction, choose the pattern that matches your sander's pad whenever possible.
● What's the advantage of the ceramic/alumina blend over standard aluminum oxide?
Ceramic grains are self‑sharpening – they fracture at a microscopic level to expose fresh cutting edges. This allows the disc to maintain a constant cut for much longer on hard materials like stainless steel, hardened wood, and gel coat. The alumina component provides a smooth finish on softer materials. This blend gives you aggressive cutting performance, extended life, and consistent results across a wide range of applications.
● Can I use these discs for wet sanding automotive clear coat?
Absolutely. The discs are fully waterproof. For clear coat finishing, use water as a lubricant with grits 1000‑2000 to level orange peel, then 3000‑5000 for fine refinement, and 7000‑10000 for a mirror polish. Wet sanding reduces heat (prevents burn‑through), eliminates airborne dust, and produces a scratch‑free finish. The 8‑hole pattern allows water to drain away from the surface during wet sanding.
● How do I choose the right grit for removing rust from metal?
For heavy rust removal, start with 60‑80 grit to cut through thick rust or scale quickly. Once the majority of rust is gone, switch to 120‑180 grit to smooth the surface. For final pre‑paint preparation, use 240‑400 grit. Always use dry sanding for rust removal with a dust extractor – the 8 holes will help evacuate metal dust efficiently. For light surface rust, you can start directly with 120‑150 grit.
● Are these discs suitable for hardwood flooring and parquet?
Yes. For hardwood and parquet, use 60‑80 grit for aggressive removal of old varnish or heavy scratches. Then 100‑120 grit for leveling, 150‑180 grit for smoothing, and finish with 240‑320 grit before applying new finish. The open coat anti‑clog design prevents resin and dust from loading on the disc, even when sanding resinous woods like oak or teak. Use dry sanding with vacuum extraction for best results.
