3M 068060-67233 Disc Hd-Dh X-Extra Coarse 60+ 4-1/2″ X 7/8

This 3M Scotch-Brite? Heavy Duty Surface Conditioning Disc is designed for aggressive prep work, like taking down thick welds, removing rust, and heavy burrs. It uses a very tough, non-woven web with an X-Extra Coarse grade (60+) to rapidly clean and refine a surface before a finer finishing stage, improving efficiency on demanding metal fabrication tasks.

• Aggressive Cleaning: The X-Extra Coarse material removes material quickly, allowing you to blend thick weld beads and strip heavy coatings or rust much faster than standard discs.
• Consistent Finish: Unlike traditional grinding discs, this surface conditioning material leaves a more uniform, satin pattern, reducing the amount of subsequent finishing work needed.
• Durability and Conformability: The robust non-woven construction resists loading and won’t splinter, offering a longer service life while remaining flexible enough to handle contours and irregular surfaces.

Who this is best for:

Fabrication shops, welders, and maintenance crews who regularly deal with heavy metal removal, weld burn cleanup, and deep rust stripping on carbon steel, stainless steel, or other hard metals using a standard 4-1/2 inch angle grinder.
