3M 7000120558 Scotch-brite Sc-dh Disc 3 Inch Hook Loop

Product Description

The 3M 7000120558 is a Scotch-Brite SC-DH Surface Conditioning Disc designed for cleaning, blending, deburring, and finishing applications across a range of materials. At 3 inches in diameter, this non-woven disc mounts to right-angle grinders via a hook-and-loop attachment system, making disc changes fast during multi-step finishing work. The open-web, non-woven fiber construction conforms to irregular and contoured surfaces without undercutting or damaging the base material. It is suited for use on metal, composite, plastics, and other substrates. Licensed tradespeople and finishing professionals in fabrication, HVAC sheet metal, and general maintenance use this disc for surface prep and conditioning tasks.

This disc is used in light to medium surface conditioning tasks on flat, curved, and irregular workpiece profiles. The conformable construction makes it effective on weld zones, edges, and contoured geometry where rigid abrasive discs would remove too much material. It is appropriate for both shop-floor fabrication environments and field service applications where a right-angle grinder is the primary tool. The hook-and-loop mount allows rapid swaps between grades during multi-step finishing sequences, reducing downtime between passes.

Key Features

• Non-woven fiber construction conforms to contoured and irregular surfaces without gouging base material
• Open-web material runs cool and resists loading for extended operation
• Hook-and-loop attachment system enables fast disc changes during multi-step finishing
• Suitable for metal, composite, plastics, and other materials
• 3-inch diameter sized for right-angle grinder use

Compatibility

Designed for use with right-angle grinders and die grinders that accept 3-inch hook-and-loop surface conditioning discs.

Installation Notes

Installation is performed by pressing the disc firmly onto a compatible hook-and-loop backup pad mounted to a right-angle grinder. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Inspect the backup pad hooks for wear before each use, as a degraded pad reduces disc retention during operation. Always operate at or below the maximum RPM rating of the disc and wear appropriate eye and face protection.
