✅ Brand New | 9 Holes for Dust Extraction | Wet & Dry
💧 150mm (6") Wet & Dry Sanding Discs – 9 Hole Sandpaper Hook & Loop Pads | 80# / 180# / 320# Grit
Professional ceramic‑grade discs for hardwood, steel, auto body, stone, and gel coat – wet or dry grinding
🛠️ Power through tough materials with less dust and longer disc life. Whether you're grinding steel on a shipbuilding project, removing old gel coat from a boat, sanding hardwood floors, or prepping auto body panels, these 6" (150mm) wet/dry sanding discs deliver outstanding cutting performance. The 9‑hole pattern works with dust extraction systems to keep your workspace clean during dry sanding, or you can add water for wet sanding to reduce heat and clogging. Available in three targeted grits: 80# for aggressive material removal and rust stripping, 180# for surface smoothing and scratch reduction, and 320# for fine finishing before primer or clear coat. Made with high‑quality aluminum oxide (ceramic-grade self‑sharpening grains) on a durable latex paper backing, these discs are built for the metal, parquet, and automotive industries. Use them on steel, stainless, hardwood, varnish, gel coat, stone, granite, Corian, and even light weld grinding.
⭐ Key Features – Why Professionals Choose These 6" Wet/Dry Discs
-
💧Wet or dry operation – Use dry with dust extraction or add water for wet sanding to reduce heat, prevent clogging, and achieve smoother finishes on paint, gel coat, and metal.
-
🕳️9‑hole dust extraction pattern – Compatible with most 6" random orbital sanders, effectively removes sanding dust during dry applications.
-
🔢Targeted grit selection: 80# / 180# / 320# – 80# for aggressive grinding of steel, rust, old paint, and varnish; 180# for smoothing hardwood and removing scratches; 320# for fine finishing before painting or polishing.
-
⚙️Ceramic‑grade self‑sharpening aluminum oxide – Maintains constant cutting speed over long periods. Outlasts standard abrasives on hard materials like steel, stainless, and stone.
-
📏Standard 150mm (6") diameter – Fits all 6" hook‑loop orbital sanders from major brands (DeWalt, Makita, Bosch, Festool, Milwaukee, etc.).
-
🔄Hook & loop backing – Quick disc changes, secure grip during high‑speed operation, and easy removal.
-
🏭Wide application scope – Artificial stone, furniture & wood products, metal, automobile, jewelry, shipbuilding, parquet flooring, gel coat, welds, and more.

💡 Performance tips: For dry sanding, connect a vacuum to your sander's dust port to utilize the 9‑hole pattern – this dramatically reduces airborne dust and extends disc life. For wet sanding, spray a small amount of water onto the surface or disc to keep it lubricated. The self‑sharpening ceramic grains work best under moderate pressure – let the abrasive do the work.
❓ Frequently Asked Questions
🔹 1. What's the difference between these discs and regular dry‑only discs?
These discs feature a special latex paper backing that resists water, allowing you to sand wet without the disc falling apart. Wet sanding reduces heat, prevents clogging, and produces a finer finish – essential for gel coat, auto clear coat, and metal polishing. Regular dry‑only discs cannot be used with water.
🔹 2. Will the 9‑hole pattern work with my sander's dust extraction?
Yes – 9 holes is a common pattern for 6" random orbital sanders (many DeWalt, Makita, Bosch, and Festool models). The holes align with most sander pads that have a multi‑hole configuration. Even if your sander has a different number of holes (e.g., 8 or 10), the dust extraction will still function, though efficiency may vary.
🔹 3. Why only 80, 180, and 320 grit? What about finer grits?
These specific grits are chosen for the most common professional applications: 80 for aggressive stock removal and rust/paint stripping, 180 for intermediate smoothing, and 320 for fine finishing before primer or clear coat. For finer polishing (600‑1500+), please see our other listings. This set covers 90% of metal, wood, and auto body prep work.
🔹 4. Can I use these discs on stainless steel and welds?
Absolutely – the self‑sharpening aluminum oxide is ideal for stainless steel and mild steel. Use 80 grit for aggressive weld seam removal or heavy rust, then 180 grit to smooth the surface, and 320 grit to prep for brushing or painting. For best results on stainless, use wet sanding to prevent heat discoloration.
🔹 5. Are these discs suitable for gel coat and boat repair?
Yes – they are specifically mentioned for gel coat sanding. Use 80 grit for removing damaged gel coat, 180 grit for fairing and smoothing, and 320 grit for final sanding before polishing. Wet sanding is highly recommended for gel coat to avoid clogging and achieve a smooth finish.
🔹 6. How many discs come in a pack? Can I mix grits?
You can select each grit individually – choose the quantity you need for 80#, 180#, or 320#. For mixed packs (e.g., 10 of each grit), simply add each grit to your cart. Contact us for bulk or custom assortment requests; we're happy to help.
