3M WetorDry Polishing Papers, 6-Piece Assortment
Innovations in the jewelry industry have taken certain polishing processes away from tedious buffing with large machines and have placed control back into the hands of the jeweler with the aid of the flex-shaft. These 3M Polishing Papers work well either mounted onto a flat surface, such as a paint stick or small piece of wood, or in the Split Mandrel flexible shaft accessory. Used like sandpaper, its abrasive load is much higher than those of WetorDry paper.
Flexible papers of silicon oxide are coated in varying concentrations of abrasive measured in microns in a range equivalent to 400 – 8000 grit in sandpaper. They can be used with a split or tapered mandrel (use higher speeds and in steps from higher microns to lower to achieve an excellent polish), on a flat surface or wrapped around a piece of wood. Although they work well on all metals, their soft, flexible construction will give a very good final polish on silver, gold and platinum.

Cleverwerx offers an excellent assortment of polishing papers especially chosen for beginners seeking an alternative to polishing with a solid bar compound. With a split cylinder mandrel or tapered mandrel, load a strip of polishing paper the same way you would sandpaper. You can guide your handpiece into tight corners, and in and around rings. These little papers will speed up your fabrication process. When used, send your used papers to the refinery. No waste here!
You will find a 6-pc, Assorted, 1-30 Micron*, 4-1/4 x11-in., Aluminum Oxide / Silicon Carbide.
The technical info: 3M polishing papers with super-flexible, non-woven backings for polishing flat or curved softer surfaces like acrylic, polyurethane, solid surface composites, fiberglass, aluminum, precious metals and finished wood. A package includes one each of 1, 2, 3, 9, 15 and 30 micron sheets. Use with or without water. Work in sequence from coarsest to finest grade. Cut into strips for Sanding Sticks or make bands using tape for Finger Sanders.
*What's a Micron and how does it differ from a Grit? Good question, and we have the answer. The term "grit" pertains to little uneven chunks of abrasive particles scattered over a square inch. For example, 400 grit is essentially 400 tiny little pieces of sand sprinkled to make one square inch. The HIGHER the number, the SMOOTHER the abrasive surface. A Micron is a calibrated size of the individual abrasive. A 4 micron particle is much TINIER than an 80 micron particle. A 4 micron is your golfball, and an 80 micron is your beachball. Therefore lots of beachballs will be a rough surface and lots of golfballs will be a smoother surface. Trying to feel the roughness between your fingers can be difficult, therefore 3M has colored-coded their polishing sheets by micron.
