3M 7100141692 Hook Loop Disc 320 Grit 6 in Ceramic

Product Description

The 3M 7100141692 is a 6-inch hook and loop abrasive disc engineered for fine finishing work on coated and bare surfaces. Part of the 3M 775L Series, this disc uses a ceramic abrasive bonded to a film polyester backing for consistent cut and long service life. The 320-grit, extra fine rating makes it well-suited for final sanding passes where surface smoothness is the priority. With 280 vacuum holes built into the disc, dust extraction is optimized when paired with a dust-collection-equipped random orbital sander. Licensed tradespeople and shop technicians who demand tight surface prep tolerances rely on this type of disc for production finishing applications.

This disc is designed for use with random orbital sanders in both residential and commercial finishing environments. Typical applications include final sanding of wood, composites, and painted surfaces before topcoat or clear application. The hook and loop attachment system allows fast disc changes on compatible random orbital sander pads, reducing downtime during multi-stage sanding operations. The purple film backing helps resist tearing and edge curl under sustained use.

Key Features

• 320-grit ceramic abrasive for extra fine surface finishing
• 6-inch diameter hook and loop disc for quick pad attachment and removal
• Film polyester backing resists tearing and maintains disc shape under load
• 280 vacuum holes for efficient dust extraction during use
• Maximum rated speed of 12,000 RPM for compatibility with standard random orbital sanders
• Part of the 3M 775L Series, designed for consistent cut performance across disc life

Compatibility

Designed for use with random orbital sanders equipped with a hook and loop sander pad and compatible dust extraction systems. The 280-hole vacuum pattern supports high-efficiency dust collection on sanders with matching vacuum configurations.

Installation Notes

Attach to a clean, dry hook and loop sander pad by aligning the disc and pressing firmly until the hook and loop surfaces engage fully. Inspect the sander pad for worn or contaminated hooks before attaching a new disc, as damaged pads reduce holding strength and can cause disc slippage. Do not exceed the 12,000 RPM maximum rated speed. Disconnect the sander from power before changing discs.
