BIG MINI SCRATCH ERASERS 3/4"

These 3M Scratch Erasers are the perfect balance between the Mini 1/2" size and the Chubby Scratch Erasers. They Remove Scratches (!) in hard-to-reach areas: inside larger rings, tubular items, and can also be used for bracelets and cuffs. 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). (Actual shank may look different than pictured) Works great with the "SAVE-YOUR-HANDS TOOL" or the JOOLTOOL Flexshaft & HD Handpiece. This is one of Anie’s favorite abrasives. This COMBO SET includes COARSE, MEDIUM, FINE, SOFT FINE and VERY FINE variants.  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. Instead, it burnishes and spreads it along the surface. Simply follow up with the FELT wheel for a finished, polished look.   Note: Pictures below show the Chubby Scratch Erasers but the Skinny Scratch Erasers can be used in a similar manner. 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.
