Also known as the 3M™ Scotch-Brite EXL Unitized – COARSE. This is one of Anie’s favorite abrasives.

Jewelry applications: This COARSE grade is great for very deep scratches and surface imperfections on precious metals. It is also great for removing deep porosity & coarse parting lines in jewelry castings. Follow up with the MEDIUM, FINE and VERY FINE grades, then the FELT wheel for a finished, polished look.
Automotive and Woodworking applications: This abrasive is ideal for heavy deburring of any metal alloy as well as many plastics and composites. Perfect for smoothing the heel of turning tools (to avoid bruising the wood during turning).


It’s made of aluminum oxide impregnated in a non-woven web, which resists loading and has an extremely long life. It also resists smearing and minimizes heat buildup on the work piece.

Note: make sure to mount this abrasive onto a Backpad before use.
