3M 7100010665 Hookit Paper Disc 5 Inches P320

Product Description

The 3M 7100010665 is a 5-inch Hookit paper abrasive disc designed for surface preparation and finishing work across a range of substrates. Built on a C-weight paper backing, the disc uses aluminum oxide as its abrasive mineral, delivering consistent cut and durability in sanding applications. The P320 grit rating places it in the fine-finishing range, making it well suited for smoothing between coats or refining surfaces before final finish. An open-coat construction reduces loading, extending usable disc life in production or repair environments. Each disc is sold individually and attaches via the Hookit hook-and-loop fastening system.

This disc is used in automotive body repair, wood finishing, metal preparation, and general surface refinishing. The Hookit attachment system allows fast disc changes on compatible random orbital and orbital sanders, making it practical in high-volume or time-sensitive work environments. The P320 grit and load-resistant coating make it especially effective for intercoat scuffing and fine stock removal where surface quality matters. Trade painters, body technicians, and finishing carpenters are the primary installers and users of this product.

Key Features

• P320 fine grit aluminum oxide abrasive for controlled stock removal and surface finishing
• C-weight paper backing provides flexibility and conformability on contoured surfaces
• Open-coat construction resists loading and extends abrasive service life
• Hookit hook-and-loop attachment for tool-free, fast disc changes

Compatibility

Designed for use with Hookit hook-and-loop compatible orbital and random orbital sanders that accept 5-inch discs with no hole pattern.

Installation Notes

Attach the disc firmly to a clean, compatible Hookit sanding pad before use. Ensure the sanding pad surface is free of debris that could prevent full disc contact and cause uneven wear. No tools are required for disc attachment or removal. Always operate the sander within its rated speed and use appropriate respiratory protection when sanding generates fine dust.
