❓ Frequently Asked Questions – 4" No‑Hole Wet/Dry Sanding Discs
● Why no holes? Shouldn't I have dust extraction?
Many 4" angle grinders, drills, and cordless screwdrivers do not have vacuum dust extraction ports. For those tools, a holed disc is pointless – the holes just let dust escape without suction. More importantly, when wet sanding, water would be pulled into the tool through holes, causing damage and safety hazards. Our no‑hole design works perfectly on all 4" tools and is the preferred choice for wet sanding applications like glass polishing, stone finishing, and paint sanding.
● Can I use these discs for wet sanding on glass and stone?
Absolutely. The waterproof backing and synthetic resin bonding make these discs ideal for wet sanding glass, stone, granite, and marble. Use with water to lubricate the surface, reduce heat, and prevent clogging. Start with 240‑400 grit to remove scratches, then progress to 1000‑3000 grit for smoothing, and finish with 5000‑10000 grit for a brilliant polish. Always wet sand at higher grits to achieve a flawless, scratch‑free finish.
● What grit should I use for paint removal on wood vs. metal?
For paint removal on wood, start with 60‑80 grit to strip heavy paint, then switch to 120‑150 grit to smooth the surface without damaging the wood. For paint removal on metal (auto body, machinery), use 80‑120 grit for aggressive stripping, then 240‑400 grit to prepare for primer. Always finish with the appropriate finer grits based on your final coating – 600‑1000 grit for primer sanding, 1500‑3000 for clear coat.
● Can I use these discs on rubber, leather, and plastic?
Yes. The discs are designed for versatile use. On rubber and leather, use 240‑400 grit for light surface preparation and 600‑1000 grit for fine finishing – always dry sand with low speed to avoid heat buildup. On plastics, use 400‑800 grit for sanding and 1000‑3000 grit for polishing, preferably wet sanding to prevent melting. The open‑coat nature of the abrasives helps prevent clogging on soft materials.
● Will these discs fit my angle grinder or drill?
Yes – as long as you have a 4" (100mm) hook & loop backing pad attached to your angle grinder, drill, or cordless screwdriver. Many angle grinders accept hook pads via a threaded arbor or adhesive backing. For drills, you can purchase drill‑mounted 4" hook pads. These discs are also compatible with standard 4" orbital and eccentric sanders that use hook & loop attachment.
