The Dremel is a power tool that allows craftsmen to carve, engrave, sand and polish using a large number of attachments. The Dremel is often thought of as a tool for woodworkers, but with its array of stone-polishing attachments, it is ideal for stone sculptors and rock collectors as well. The variety of polishing attachments offered for the Dremel allows artists who work with stone to give a final high-gloss polish to any type of rock, soft or hard, to bring out the best in stone carvings and add an impressive shine to rock collections.

  1. 1

    Decide the type of attachment you'll need based on the stone you want to polish. Dremel offers a variety of polishing attachments. Harder stones may require brass or stainless steel polishing brushes; medium-hard might be better served with a bristle polisher, and nylon or abrasive polishers work best on soft stone.

  2. 2

    Find a well-lit area to work on your stone. Use a jeweller clamp to secure the stone you want to polish. Apply polishing agent liberally to the surface of your stone as you polish. Start with the attachment that best fits your stone type and keep a light pressure on the surface of the stone as you polish, moving the polishing attachment in small, slow circles over the surface of the stone. Avoid staying in one place too long unless you are trying to remove an imperfection.

  3. 3

    Turn the stone in the clamp when the shine begins to come through. Continue to polish the entire stone until you have a shine over the entire stone, then switch to a nylon attachment for the final polishing. Wipe the finished stones free of excess polishing agent with a dry, lint-free rag.

Tips and warnings

  • Apply a little water to your stone from time to time. This acts as a protective element and will help bring out the polish.
