3M 7010384766 Regalite Hookit Abrasive Disc 80 Grit 5.5 in

Product Description

The 3M 7010384766 is a heavy-duty hook-and-loop abrasive disc designed for high-production sanding and surface preparation work. Built on a tough paper backing and loaded with Regalite mineral abrasive, this disc delivers fast cut rates and extended service life compared to conventional coated abrasive discs. At 5.5 inches in diameter and 80 grit, it targets aggressive material removal while maintaining consistent scratch patterns. The hook-and-loop attachment system — compatible with Hookit-style backup pads — allows fast disc changes without interrupting workflow. Licensed tradespeople and skilled technicians use this disc in bodywork, fabrication, and surface finishing applications.

This disc is suited for use on metal, wood, and composite surfaces where rapid stock removal at medium-coarse grit is required. The 80-grit cut makes it appropriate for initial shaping, weld blending, and preparation passes before progressing to finer grits. At 5.5 inches, it fits edger and inline sander configurations that use Hookit-compatible hook-and-loop pads. Typical users include auto body technicians, metal fabricators, and finish carpenters working in both shop and field environments.

Key Features

• Regalite mineral abrasive for fast cut rates and extended disc life
• 80 grit for aggressive material removal and surface shaping
• 5.5-inch diameter fits edger and inline Hookit-compatible sander pads
• Hook-and-loop backing enables rapid disc changes without tools
• Tough paper backing resists tearing under production sanding loads

Compatibility

Designed for use with Hookit hook-and-loop compatible backup pads and sanding tools that accept 5.5-inch discs.

Installation Notes

Attach the disc firmly to a clean, dry Hookit-compatible backup pad before use, ensuring full surface contact to prevent edge lifting. Inspect the backup pad for worn hook material before mounting — a degraded pad will reduce disc adhesion and can cause the disc to release under load. Disconnect the sander from its power or air source before swapping discs. Wear appropriate respiratory protection and eye protection when sanding, per applicable safety standards.
