Description
3M Scotch-Brite Surface Conditioning Disc, Very Fine, 5 in – SB69421 is a professional 3M abrasive for controlled sanding and surface preparation. The part number determines the exact grade, size and attachment format, helping users maintain a predictable scratch pattern and choose the correct next step in the finishing process.
Features
- Open nonwoven construction conforms to contours and irregular surfaces better than rigid coated abrasives.
- Abrasive mineral is distributed through the web for consistent conditioning action as the pad or disc wears.
- Useful for scuffing, cleaning, blending and surface preparation where aggressive stock removal is not required.
- Resists loading better than conventional sandpaper in many cleaning and conditioning applications.
- Can be paired with the appropriate 3M holder or disc pad for controlled hand or machine use.
