❓ Frequently Asked Questions – 3″ to 7″ Sanding Discs
● Which size disc should I use for my angle grinder or sander?
Always match the disc diameter to your tool's backing pad. 3″-4″ discs are ideal for compact angle grinders and detail sanders. 5″ is the standard for most random orbital sanders (Dewalt, Bosch, Makita). 6″-7″ discs are for larger professional sanders and angle grinders, providing faster coverage on big surfaces. Check your tool's pad size before ordering.
● Can I use these discs on automotive paint?
Yes – for dry sanding primer and paint. Use 240-400 grit for primer surfacing, 600-800 for scuffing clear coat, and 1000-2000 for dry polishing. For wet sanding clear coat to remove orange peel, we recommend our dedicated waterproof discs. These discs are optimized for dry applications.
● What grit should I use for wood sanding vs. metal polishing?
For wood: start with 60-80 for rough shaping, 100-150 for smoothing, 180-240 for pre‑finish, 320-400 for final sanding before stain/sealer. For metal: use 60-120 for rust/scale removal and deburring, 150-240 for surface smoothing, 320-600 for fine finishing, 800-2000 for polishing. Always progress through grits in steps (no more than double the previous grit).
● How long do these discs typically last?
The aluminum oxide abrasive is designed for durability. Under normal light to medium pressure, an 80‑grit disc can sand approximately 15‑20 sq. ft. of hardwood or 10‑15 sq. ft. of auto primer. Avoid pressing too hard – let the tool's weight do the work to maximize disc life. Proper storage (cool, dry place) also extends shelf life.
● Are these discs suitable for angle grinder use?
Yes – for light to medium sanding and grinding on flat or slightly curved surfaces. However, for heavy weld removal or aggressive metal grinding, we recommend using dedicated flap discs or fiber discs. These hook & loop discs perform best with orbital sanders or angle grinders equipped with a soft backing pad for finishing work.
