Diamond-dust Felt-tip Brush Trio
Left to right: 5x12 Cone, 8x12 Egg and 9x16 Cone.
These tools can be used in a battery-powered dremel or by hand in a pin vise.
Three excellent brushes to Diamond Dust your coin's ancient patina to an incredible luster. Each of these felt-tipped Dremel tools can be used with any diamond grit. And, they can be used over and over. Changing grits? No problem. Just rinse off the grit under running water. Let Dry, and use again. These same three tips have lasted me for over two years. Don't forget, you'll need the diamond dust, as well as some water-solvent KY jelly.
One last reminder, always begin with the 1200 Grit diamond dust!
