3M 7100054378 Scotch-brite Sc-dh 7 Inch Conditioning Disc

Product Description

The 3M 7100054378 is a Scotch-Brite SC-DH Surface Conditioning Disc designed for cleaning, blending, deburring, and finishing across a wide range of materials. Built with a durable, non-woven fiber construction, the disc conforms to irregular and contoured surfaces without undercutting or damaging the base material. At 7 inches in diameter, it mounts on right-angle grinders via a hook and loop attachment system. Weighing 0.15 pounds, it is a lightweight consumable suited for multi-step surface prep workflows on metal, composite, plastics, and similar substrates. The open web construction allows the disc to run cool and resist loading during extended use.

This disc is appropriate for both shop and field use in metal fabrication, welding cleanup, and general surface preparation tasks. It fits into multi-step finishing processes where maintaining surface integrity is critical. Trades including metal fabricators, welders, and industrial maintenance techs typically deploy this disc as a first-step conditioning tool before finer finishing passes. The aluminium oxide (AO) mineral type makes it well-suited for ferrous and non-ferrous metals as well as composites and plastics.

Key Features

• Non-woven fiber construction conforms to contoured and irregular surfaces without gouging or undercutting
• Open web material runs cool and resists loading for extended operational life
• Hook and loop attachment system enables fast disc changes in multi-step finishing processes

Compatibility

Designed for use with right-angle grinders equipped with a hook and loop disc backing pad accepting 7 inch non-woven conditioning discs.

Installation Notes

Disc mounting and removal should be performed with the grinder powered off and unplugged or with the battery pack removed. Verify the grinder backing pad is rated for the disc diameter and the tool RPM rating meets or exceeds the disc maximum speed before operation. Inspect the disc for tears or damage before each use and discard if the attachment surface shows wear that could cause detachment during operation.
