SKU: S-3602 Categories: ,


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

Jewelry applications: This MEDIUM grade is slightly harder and denser than the FINE grade, great for achieving flat, crisp finishes on Raw Castings. It’s “Web-Like” Structure blends the metal and will blend away reasonably deep scratches and scuff marks on precious metals. It is also great for removing porosity & parting lines in jewelry castings. It does not remove your precious material. Instead, it burnishes and spreads it along the surface. Simply follow up with the FINE grade, then the FELT wheel for a finished, polished look.

Automotive and Woodworking applications: This abrasive is ideal for deburring and polishing 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.
