3M 7100046326 Hook Loop Disc 5 in 120 Grit Ceramic

Product Description

The 3M 7100046326 is a 5-inch hook and loop abrasive disc from the 3M 775L Series, designed for coated abrasive grinding and finishing applications. Built with a ceramic abrasive material and rated at 120 grit (fine grade), this disc delivers consistent stock removal and surface conditioning on metal, composite, and painted surfaces. The hook and loop backing system allows for fast disc changes without tools, making it a practical choice for production environments where downtime between disc swaps affects throughput. Licensed trades using angle grinders or random orbital sanders in metal fabrication, bodywork, or general surface prep will find this disc a reliable consumable.

This disc is suited for professional surface preparation tasks in light industrial, fabrication shop, and trade service settings. The 120-grit fine grade makes it appropriate for intermediate finishing passes where a smooth surface profile is needed before final coating, priming, or inspection. It attaches to any 5-inch hook and loop backup pad compatible with standard random orbital or angle-head sanders used in HVAC panel work, ductwork finishing, plumbing fixture prep, and general metalwork.

Compatibility

Designed for use with 5-inch hook and loop backup pads on random orbital sanders and angle grinders configured for hook and loop disc systems.

Installation Notes

Attachment and removal require no tools — align the disc face to the backup pad and press firmly to seat the hook and loop interface. Before mounting or removing discs, ensure the power tool is fully powered off and disconnected from its power source. Inspect the backup pad for worn hooks that may prevent secure disc retention, as a loose disc is a safety hazard at operating speeds. Wear appropriate PPE including eye protection and gloves when performing any grinding or sanding operation.
