3M 7100010641 Hookit Abrasive Disc 5 Inch P500 Grit

Product Description

The 3M 7100010641 is a coated abrasive disc engineered for high-production sanding operations in industrial and trade environments. Built on a C-weight paper backing with premium aluminum oxide mineral, this 5-inch disc delivers fast, aggressive cut across a broad range of materials. The open-coat construction paired with a load-resistant coating keeps the disc surface clear longer, extending abrasive life. Attachment is handled by the Hookit hook-and-loop system, which allows quick disc changes and disc reuse without tools. The disc is rated to 12000 RPM and finished to a P500 grit for fine material removal and surface prep work.

This disc is suited for general-purpose and production sanding on paint, primer, wood, metal, plastic, and composites including fiberglass. It performs well on both flat and contoured surfaces and is a common choice for body shop, fabrication, and industrial finishing operations where consistent cut rate and surface finish at a fine grit are required. The Hookit attachment system makes it compatible with random orbital and orbital sanders equipped with hook-and-loop backup pads.

Key Features

• Premium aluminum oxide mineral for fast cut and durability across multiple surface types
• C-weight paper backing provides extra rigidity and durability over lighter paper grades
• Open-coat construction resists loading on paint, wood, and composite surfaces
• Load-resistant coating extends disc life in high-production environments
• Hookit hook-and-loop attachment allows tool-free disc changes and disc reuse
• 12000 RPM max speed rating suitable for standard orbital sanding equipment

Compatibility

Designed for use with Hookit hook-and-loop backup pads and random orbital sanders accepting 5-inch hook-and-loop discs. Compatible with sanding operations on paint, primer, wood, metal, plastic, and composites including fiberglass.

Installation Notes

Installed by hand onto a compatible Hookit backup pad — no tools required. Confirm the sander and backup pad are rated for the disc diameter and RPM before use. Inspect the backup pad face for debris or worn hooks before attaching a new disc to ensure full engagement. Disconnect the sander from power before changing discs.
