Compare 5" Gold A/O 8 Hole and Premium Purple Film No Hole hook & loop discs. Learn which sanding disc suits your finish quality and dust control needs.
Quick answer
Choose Gold A/O 8 Hole discs for general sanding with dust extraction, and Premium Purple Film No Hole discs for a finer finish on delicate surfaces.
Why the backing material matters
The Gold A/O disc uses an aluminum oxide grain on a standard paper backing with eight pre-punched holes, making it compatible with dust-extraction sanders. The Premium Purple Film disc uses a film backing (similar to Velcro loop material) with no holes, which provides a stiffer, more uniform sanding surface that resists tearing and delivers a consistent scratch pattern.
Dust control vs. finish quality trade-off
If your sander has a dust port and you work in a shop where airborne dust is a concern, the Gold A/O 8 Hole disc is the practical choice. The holes align with most random orbital sander patterns to pull debris away. However, the holes can leave slight witness marks on ultra-fine finishes. The Premium Purple Film disc, lacking holes, creates a continuous sanding surface that avoids those marks, but you'll need to manage dust separately.
Gold A/O vs Premium Purple Film: Trade-offs
- Dust extraction: Gold A/O 8 Hole discs allow dust collection through the sander; Premium Purple Film No Hole discs require external dust management.
- Finish quality: Premium Purple Film discs produce a more uniform scratch pattern without hole marks; Gold A/O discs may leave faint marks on final passes.
- Durability: The film backing on Premium Purple discs resists tearing better than paper-backed Gold A/O discs, especially on edges and contours. If you frequently sand profiles or edges, the film disc will last longer.
