🔧 Whether you're prepping auto body panels, refinishing hardwood floors, or polishing delicate metal surfaces, inconsistent sanding results and frequent disc changes kill your workflow. Our 75mm/100mm wet & dry hook and loop sanding discs eliminate those frustrations. The premium aluminum oxide grain cuts fast yet leaves a swirl‑free finish, while the waterproof resin bond allows seamless transition from dry sanding to wet sanding — reducing dust and extending disc life. From aggressive stock removal (grit 60) to mirror‑edge polishing (grit 10000), this all‑in‑one grit range serves auto body techs, woodworkers, metal fabricators, and home DIYers who demand professional-grade results without buying multiple pads.
✨ Key Features of Our Wet/Dry Sanding Discs
💧🌫️
True Wet & Dry Performance – Waterproof aluminum oxide coating allows you to sand with water (reduces clogging & dust) or dry for rapid material removal. Perfect for automotive paint prep and marine gelcoat work.
🔄
Hook & Loop (Velcro) Backing – Quick-change system; discs attach securely to any 75mm or 100mm random orbital sander or backing pad. No adhesive residue, no tearing, just instant swap between grits.
⚙️
Ultra‑Wide Grit Range 60 ➝ 10000 – From heavy stock removal (60–240 grit) to fine finishing (320–800) and ultra‑polishing (1000–10000). One package covers rough shaping to final mirror shine.
🟣
Premium Purple Aluminum Oxide – Engineered for long life and consistent cut. Resists loading on both softwoods and metals; the vibrant purple color helps easily identify used vs. fresh discs.
🔘
Non‑Hole Design (Hole‑Free) – Ideal for wet sanding and continuous surface applications where suction holes aren’t needed. Provides uniform support for detail work, edge sanding, and hand use.
📏
Two Popular Sizes: 75mm & 100mm – Fits standard orbital sanders, back-up pads, and manual sanding blocks. Choose the right diameter for contours or flat panels.
❓ Frequently Asked Questions
🟢 Can I use these 75mm/100mm discs on my random orbital sander (ROS)?
Absolutely! Both 75mm and 100mm sizes are standard for most orbital sanders and backing pads. The hook-and-loop backing grips firmly, and the non-perforated design works perfectly with sanders that don’t require dust extraction holes (especially for wet sanding). Just match the disc diameter to your sander’s pad size.
💧 Are these discs truly waterproof for wet sanding?
Yes — the resin bond is specifically engineered for water immersion. Soak the disc for a few minutes before use, then sand with water to reduce clogging and achieve an ultra-smooth finish. After wet sanding, rinse and air-dry the disc; it will hold up for multiple sessions.
⚡ What’s the difference between grit 60 and grit 10000? When should I use each?
Grit 60 is coarse and aggressive — perfect for stripping paint, removing rust, or shaping filler. Grit 10000 is an ultra-fine polishing grit that leaves a near-mirror finish on metals, clear coats, or resin. For typical auto-to-wood projects, start coarse (60-240), move to medium (320-600), then finish with fine/polishing grits (800-10000). The wide range saves you from buying separate discs.
🔘 Why are these discs hole-free (non-perforated)? Does that affect dust collection?
Non-perforated discs provide a continuous surface, which is ideal for wet sanding (water won’t leak through) and for delicate contour work where holes might leave marks. For dry sanding with dust extraction, we recommend using a perforated pad and backing pad with holes — but many users prefer the flexibility of hole-free for hand sanding and multi‑material use. If you need dust extraction, simply use these discs with a dust-collection sander adapter or switch to our hole-punched version (contact support).
🛠️ Will the hook and loop backing wear out after frequent disc changes?
The hook material on our discs uses high-density industrial loops that withstand hundreds of attachment cycles. To maximize life, ensure your sander’s pad is clean (no dust or debris) before attaching a new disc, and peel discs off gently rather than yanking. Under normal use, the backing outlasts the abrasive itself.
📦 Do I need to buy 75mm and 100mm discs separately? Can I get a mixed grit set?
Our assortment includes both sizes in the complete 60-10000 grit range. For bulk or specific grit packs, please check the options available in the dropdown menu. We offer individual grit packs and value bundles — just select the size and grit combination you need. Every disc is individually labeled for easy identification.
