❓ Frequently Asked Questions – Get the answers you need
🔹 1. Will these sanding discs fit my specific orbital sander model?
Yes – they are standard hook-and-loop discs compatible with any 5″, 6″, 7″, or 9″ orbital sander (including DeWalt, Bosch, Makita, Festool, Craftsman, Ryobi, Milwaukee, and more). The hole pattern aligns with most dust extraction systems. If your sander has a different hole count, the disc still works for sanding, but dust collection may be slightly reduced. For best results, match the diameter to your sander’s pad.
🔹 2. How do I choose the right grit for my project (wood vs metal vs paint)?
For aggressive material removal (rough wood, thick paint, rust) pick 40–80 grit. For smoothing surfaces and removing small scratches (deburring, between coats) choose 120–240 grit. For ultra-fine polishing before staining or clear coat, 320–600 grit is ideal. Our sanding discs handle wood, metal, drywall, and auto body filler with equal strength.
🔹 3. Does the dust extraction actually work on all sizes? And will it prevent clogging?
Absolutely. Each diameter uses a tailored hole pattern (8/6/8/10 holes) designed to maximize vacuum airflow. Dust extraction not only keeps your workspace clean but also reduces heat and clogging, extending disc life by up to 40%. For best results, use a vacuum or dust collector connected to your sander.
🔹 4. Are these discs durable for heavy daily workshop use, or just for hobbyists?
These sanding discs are built for both pro shops and home DIYers. The premium aluminum oxide grain and heat-resistant resin bond provide consistent cutting action even under continuous pressure. Users report 2x longer life than typical big-box store discs. Backed by GooBetter quality control – perfect for high-frequency sanding jobs.
🔹 5. Can I get one pack with mixed grits & diameters?
Yes! When ordering, you can select individual sizes and grits per your requirement. Many customers build “kits” by ordering multiple grits of the same diameter. For custom bundles or bulk pricing, feel free to message us. We ensure secure packaging to avoid damage during shipping.
🔹 6. Do these discs work for wet sanding?
These discs are designed for dry sanding only. Wet sanding may damage the hook-and-loop backing and reduce adhesion. For dry applications, they perform exceptionally well with dust extraction to keep the surface cool.
