Pro-source 5590012516PRO Hook Loop Disc 400 Grit 3 Inch 10 Pack

Product Description

The PRO-SOURCE 5590012516PRO is a 3-inch hook and loop abrasive disc designed for fine surface finishing work. It uses a coated aluminum oxide abrasive at 400 grit, rated Extra Fine grade, making it well-suited for final sanding passes, light material removal, and surface prep before coating or finishing. The flexible backing conforms to the work surface and allows consistent contact across the disc face. Each package contains 10 discs. These discs are installed and used by finish carpenters, auto body technicians, general contractors, and surface prep professionals who require reliable, consistent abrasive performance at fine grits.

This disc is used in residential and commercial finishing applications where a smooth, refined surface is required. Typical uses include sanding wood, metal, or composite surfaces between coats of paint or finish, removing light oxidation, and prepping surfaces for adhesives or coatings. The hook and loop attachment system allows for fast disc changes on compatible random orbital and disc sanders without tools, reducing downtime during high-volume finishing work.

Align the disc squarely on the pad before applying pressure to seat the fastening surface. Inspect each disc before use and discard any disc showing tears, uneven abrasive wear, or backing damage. Follow all applicable tool manufacturer guidelines and PPE requirements when operating power sanding equipment.
