Buying Guide
- Grit range: Choose sets with a broad range (coarse to ultra-fine) for progressively smoother finishes. Wet/dry capability is essential for reducing dust and preventing clogging.
- Backing type: Hook-and-loop backs (Velcro) allow quick disc changes on orbital sanders. Confirm compatibility with your sander’s pad pattern and hole count.
- Disc diameter: 5-inch and 6-inch discs are common for larger surfaces; 2-inch or 3-inch discs excel at detailing and tight spots.
- Material: Silicon carbide is standard for metal and hard woods; ensure discs are water-resistant for reliability in wet sanding.
- Accessory completeness: Some kits include polishing pads, wool pads, and shanks—evaluate what you actually need to avoid paying for unused parts.
- Best use cases: For finishing vs. heavy material removal—coarser grits remove material; finer grits refine and polish.
