3M 7000120779 Scotch-brite 4 Inch Clean and Strip Disc

Product Description

The 3M 7000120779 Scotch-Brite Clean and Strip Disc is a non-woven abrasive disc built for aggressive surface preparation on metal workpieces. It combines extra coarse (XCS) grade silicon carbide mineral with non-woven nylon fibers to remove rust, paint, coatings, and weld discoloration without gouging or significantly altering the base material profile. At 4 inches in diameter, it mounts via the Roloc attachment system for fast disc changes in multi-step finishing operations. Licensed tradespeople and fabricators working on steel, stainless, and similar substrates reach for this disc when surface cleanliness matters as much as speed.

This disc is suited for use in both light industrial and field maintenance settings. Typical applications include pre-weld surface prep, post-weld cleanup, rust and oxidation removal, and stripping old coatings before recoating or inspection. The non-woven construction and load-resistant material resist clogging, making it effective across extended use without frequent disc changes. It is commonly used by welders, pipefitters, and maintenance technicians requiring consistent cut action with minimal base metal removal.

Key Features

• Extra coarse (XCS) silicon carbide mineral provides aggressive cutting with a fine finish
• Non-woven nylon fiber construction resists loading and clogging for consistent performance
• Removes rust, paint, and coatings without gouging or compromising workpiece geometry
• Smear-resistant properties reduce post-cleaning requirements on the work surface
• Roloc attachment system allows quick disc changeout during multi-step finishing processes
• 4 inch diameter fits standard Roloc-compatible angle grinder and die grinder backups

Compatibility

Designed for use with Roloc-compatible backup pads and angle grinders or die grinders that accept the Roloc threaded attachment system.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source. Thread the disc onto a compatible Roloc backup pad until snug before tool operation. Inspect the disc for damage before each use and do not exceed the rated operating speed for the tool and disc combination. Wear appropriate PPE including eye protection and gloves in accordance with applicable workplace safety standards.
