Turn your Dremel rotary tool into a powerful polisher with the 422 Felt Polishing Cone. Good for polishing metals, plastics, stones, ceramics and glass. Fits the 401 Dremel mandrel and likely most other rotary tools.

In fossil preparation, these felt wheels can be used with tin oxide powder, mixed into a paste, to complete a final polish on a fossil or stone. The cone will help you get into smaller spaces, polish between ammonite ribs and any irregular surface. 

  • Do not run in excess of 35,000RPM
  • 3/8" (9.5mm) Felt Polishing Wheel
  • 13mm total length
  • Pack of 4

Please note that these are not to be used with the Dremel 290 engraver (which does not have a rotary action). 

    • Guaranteed safe checkout

    What is fossil polishing?

    Polishing can be a the perfect way to enhance the beauty of a fossil. It is an aesthetic approach to fossil preparation, usually performed on fossils which either are found so abundantly that their scientific value is limited, or fossils that just 'look best' when they're polished. Sometimes they are used in arts, crafts and jewellery in their polished form. 

    Some fossils are cut before being polished, and others are left whole. Fossil polishing is something you can do at home with some very basic supplies - some good quality wet-and-dry paper in various grits (different coarseness), tin oxide polishing powder, a rotary tool with a felt wheel and some water. And of course a fossil. The best fossils and rocks for polishing are crystalline ones (e.g. calcite). The rock must be hard and non-porous for it to take a polish.
