This is a 6-inch diameter 3M Cubitron II Hookit Paper Disc (732U) with a 320+ grit. It’s designed for sanding applications, particularly on substrates that might load up a standard abrasive, and uses 3M’s proprietary grain technology to cut faster and last longer than traditional sanding discs. This means less time spent changing discs and more consistent results on your finishing work.
- Efficiency: The precision-shaped grain aggressively cuts material, requiring less pressure from the operator and shortening sanding time on large jobs.
- Durability: The extended disc life minimizes the need for frequent replacements, which reduces material cost and overall downtime.
- Consistent Finish: The 320+ grit provides a uniform scratch pattern ideal for fine finishing, blending, and preparing surfaces for primer or topcoat.
Who this is best for
This disc is ideal for body shops, woodworking professionals, and industrial manufacturers who require high-performance fine-finishing and sanding before painting or coating, especially when working on surfaces that demand a fine, consistent finish.
