Merit Abrasives 05539562623 Hook Loop Disc 80 Grit 3 in

Product Description

The MERIT ABRASIVES 05539562623 is a 3-inch hook-and-loop abrasive disc designed for surface conditioning, blending, and finishing work across metal, wood, and composite substrates. Built with aluminum oxide abrasive on a flexible non-woven backing, this disc cuts consistently without loading and conforms to irregular or contoured surfaces. Rated at a maximum of 20,000 RPM, it suits most standard angle grinders and random orbital sanders equipped with a hook-and-loop backing pad. At 80 grit, it falls in the medium grade range, making it appropriate for moderate stock removal and surface prep before finer finishing passes.

This disc is suited for metal fabrication shops, auto body work, weld blending, rust removal, and paint prep on both flat and curved surfaces. The flexible non-woven construction allows the disc to follow contours without gouging, which is useful when working on pipe, tubing, or irregular sheet metal profiles. The red disc color is typical for medium-grade aluminum oxide non-woven products. No vacuum holes are included, so this disc is not intended for use with dust-extraction backing pads that rely on through-hole suction.

Key Features

• 3-inch diameter with hook-and-loop attachment for fast disc changes
• 80 grit aluminum oxide abrasive — medium grade for surface prep and moderate stock removal
• Flexible non-woven backing conforms to contoured and irregular surfaces
• Rated to 20,000 RPM for compatibility with high-speed grinders and sanders
• No vacuum holes — solid disc face for non-dust-extraction applications

Compatibility

Designed for use with hook-and-loop backing pads on angle grinders and random orbital sanders that accept 3-inch abrasive discs.

Installation Notes

Installation is performed by pressing the hook-and-loop disc firmly onto a compatible backing pad — ensure the pad surface is clean and free of debris for secure adhesion. Confirm the tool RPM rating meets or exceeds the disc maximum of 20,000 RPM before use. Inspect the disc for tears or delamination before each use and replace immediately if damage is found. Always use appropriate eye protection and follow tool manufacturer safety guidelines when operating at high speeds.
