For grinding, attach grinding stones which can be fixed to the mandrel/shaft. Slide the grinding stone into the front of the tool where it is fully inserted and tighten. Turn your Dremel on and grind on a low setting so you don't overheat the material. Gently hold the grinding stone against the material until it wears down. You can use grinding stones, grinding wheels, chain saw sharpening stones, abrasive wheels and abrasive points to grind a material. Carbide bits tend to work best on metal, porcelain, or ceramic. Use cylindrical or triangular tips for round grinds. To grind a notch into something or grind an inside corner, use a flat disc shape. Or, use cylindrical or triangular tips for round grinds. Select a sandpaper bit and secure it in your Dremel. Sandpaper bits are available in fine through course grits, and all grades should fit on the same mandrel. Tighten the screw at the end of the sandpaper bit. Turn on your Dremel and set it between 2 and 10. Choose lower settings if you're sanding or polishing plastics or woods. Select a higher setting if you're sanding metal. While holding the material secure, run the bit across the material so that the sandpaper bit completely comes into contact with your material and sharpens or sands it. Make sure that the sanding bits are in good shape so they don't scuff or mark your material. They should fit in the drill snugly and shouldn't be worn. Have several sanding bits on hand so you can quickly replace them. To sand, you can use sanding bands, sanding discs, flap wheels, shaping wheels and finishing and detail abrasive brushes. If you've got a big job, begin with coarser bits before moving to softer bits. This can help you sand out larger scratches quickly and then you can have more control over working through the material. If you skip the coarse bit and begin with a softer bit, it will take you longer and you'll wear out the softer bit. Check the bit every minute or two to see if the bit is worn or torn. Remember to turn off and unplug the Dremel while you do this. The Dremel is an excellent tool for fine-detail polishing or polishing in tight spots. Rub a polishing compound over the surface of your object and fit your Dremel with a felt polishing tip or wheel. Start your drill at a low speed (2) and run it against the polishing compound. You should work the wheel in circles until the material is polished. Avoid using a much higher speed (don't go over 4). You can polish without using a compound, but you'll get shinier results with it. For cleaning and polishing jobs, use rubber polishing points, cloth or felt polishing wheels, and polishing brushes. Be sure to get the right kind of coarse polishing brush for the job. These bits are good for taking old paint off of metal furniture or cleaning up tools and grills.
