Jewelry applications: Excellent for “wiping off” or “blending in” 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 MINI FELT wheels or SEE-THRU Felt Polishing Discs 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.
