5 Inch Sanding Discs

Whether you are knocking back primer on a car panel, leveling a hardwood floor, or cleaning up weld scale on steel, a 5 inch hook and loop disc is the workhorse format for most random orbital sanders. FastPlus carries two abrasive lines - ceramic and aluminum oxide - both in 8-hole pattern, both in 50-pack quantities, covering 40 through 800 grit so you can run a complete job from stock removal to finish sanding without switching suppliers.

Key Takeaways
  • All FastPlus 5 inch discs use hook and loop attachment - no PSA peel-and-stick.
  • 8-hole pattern fits DeWalt, Makita, Ridgid, and most other 5 inch random orbital sanders.
  • Ceramic grain (Blue Line F65) stays sharp longer on hardwood and auto body primer.
  • Aluminum oxide (Yellow Line F25) is the right call for general wood sanding, drywall, and light metal.
  • Both lines run 40 to 800 grit, so one supplier covers your full sanding sequence.
  • 50-pack quantities keep per-disc cost low without overstocking a single grit.

Best Uses for 5 Inch Sanding Discs

Auto Body Prep

Start at 80 grit to feather edges and knock back high spots in primer. Step to 180 for guide coat work, then 320 to 400 before spraying. Ceramic F65 holds its cut through multiple panels without glazing.

Wood Sanding

Ceramic F65 at 80 to 120 grit removes mill marks fast. Switch to aluminum oxide F25 at 180 to 240 for final passes before stain.

Metal Finishing

Use F25 aluminum oxide at 80 to 120 grit to remove scale and surface rust, then step through 240 to 400 for a clean surface before primer or coating.

How to Choose the Right 5 Inch Disc

Grit

Start two grits coarser than you think you need, then step up. For paint prep, 80 to 180 to 320 is a reliable three-step sequence. For bare wood before stain, 120 to 180 to 240 is usually enough.

Hole Pattern

Both FastPlus 5 inch lines use an 8-hole pattern fitting DeWalt (DWE6421, DWE6423), Makita (BO5030, BO5041), Ridgid, and most other brands. DeWalt and Makita are registered trademarks of their respective owners. FastPlus discs are compatible replacement products not affiliated with or endorsed by those brands.

Abrasive Type

Line Abrasive Best For Not Ideal For
Blue Line F65 Ceramic Hardwood, auto body primer, high-volume work Non-ferrous metals, occasional light use
Yellow Line F25 Aluminum Oxide General wood, drywall, light metal, soft materials Extended hardwood or auto body runs

Frequently Asked Questions

01Are these hook and loop discs?
Yes. Both the Blue Line F65 and Yellow Line F25 use hook and loop attachment. There is no peel-and-stick PSA backing.
02Will these fit my 5 inch orbital sander?
FastPlus 5 inch discs use an 8-hole pattern fitting DeWalt, Makita, Ridgid, and most other brands. If your sander has a 5-hole pad, the discs will still attach with slightly reduced dust extraction.
03Which grit is best for paint prep?
For auto body paint prep: 80 grit to feather and level, 180 to refine, 320 to 400 before spraying. The Blue Line F65 ceramic holds its cut longer across multiple panels.
04What is the difference between ceramic and aluminum oxide?
Ceramic grain (Blue Line F65) is self-sharpening and lasts longer on hard materials. Aluminum oxide (Yellow Line F25) is a general-purpose abrasive suited for softer materials. FastPlus Abrasives USA - fastplus.us - stocks both lines.
05How do I know when a disc is worn out?
The signal is heat instead of cutting. If the surface gets warm quickly or the disc leaves burnished marks instead of a consistent scratch pattern, it is time to swap.
