These 3M Scratch Erasers are the perfect balance between the Mini 1/2" size and the Chubby Scratch Erasers. They clean castings and remove scratches in hard-to-reach areas: inside smaller rings, tubular items, and can also be used for bracelets, cuffs, larger rings. The coarser grades are great for deburring and the finer grades are amazing for burnishing metal & leaving a pre-polished look. Shank/mandrel diameter is 3/32″ (2.38 mm). (Shank for COARSE grade is different due to material rigidity). Works great with the "SAVE-YOUR-HANDS TOOL" or the JOOLTOOL Flexshaft & HD Handpiece. This is one of Anie’s favorite abrasives. Available in MEDIUM, FINE and VERY FINE grades. The FULL SET includes all 3 grades.Jewelry applications: This material is 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 = NO GOLD LOSS! Instead, it burnishes and spreads it along the surface. Simply follow up with the FELT wheel for a finished, polished look. Automotive, Woodworking and other 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.
